The team’s project focuses on electric propulsion, integrated aircraft technologies, and vehicle design.Electra Picture yourself at an airport a few decades from now. What does your airliner look like? It’s more efficient, with lower emissions than today’s aircraft – what kinds of designs or technology make that possible? NASA is working to answer those questions by commissioning five new design studies looking to push the boundaries of possibility for sustainable aircraft. Through NASA’s Advanced Aircraft Concepts for Environmental Sustainability (AACES) 2050 initiative, the agency asked industry and academia to come up with studies looking at aircraft concepts, key technologies, and designs that could offer the transformative solutions needed to secure commercial aviation’s sustainable future by 2050. NASA issued five awards, worth a total of $11.5 million, to four companies and one university. These new NASA-funded studies will help the agency identify and select promising aircraft concepts and technologies for further investigations. Artist’s concept of a future airliner based on the NASA Advanced Aircraft Concepts for Environmental Sustainability 2050 submission from awardee Georgia Institute of Technology. The team’s project focuses on exploring scenarios and technologies based on an aircraft concept the institute has developed, known as ATH2ENA.Georgia Institute of Technology “Through initiatives like AACES, NASA is positioned to harness a broad set of perspectives about how to further increase aircraft efficiency, reduce aviation’s environmental impact and enhance U.S. technological competitiveness in the 2040s, 2050s, and beyond,” said Bob Pearce, NASA associate administrator for the Aeronautics Research Mission Directorate. “As a leader in U.S. sustainable aviation research and development, these awards are one example of how we bring together the best ideas and most innovative concepts from the private sector, academia, research agencies, and other stakeholders to pioneer the future of aviation.” For decades, NASA has connected government agencies, industry, and academia to develop sustainable aviation technologies. In 2021, NASA launched its Sustainable Flight National Partnership, focused on technologies that could be incorporated into aircraft by the 2030s. The partnership’s research and development led to current NASA work including the experimental X-66 Sustainable Flight Demonstrator aircraft, its Electrified Powertrain Flight Demonstration project, and the development of more efficient engine cores and processes for the rapid manufacturing of lightweight composite materials.

The Pratt & Whitney project focuses on commercial aviation propulsion technologies targeting thermal and propulsive efficiency improvements to reduce fuel consumption and greenhouse gas emissions.Pratt & Whitney The new AACES awards are initiating a similar process, but on a longer timeline, focusing on technologies to help transform aviation beyond SFNP with aircraft that could enter service by 2050. The kinds of partnerships NASA develops through SFNP and AACES are critical for the agency to support the U.S. goal of net-zero aviation emissions by 2050 and to help put aviation on a path toward energy-resilience. “The AACES 2050 solicitation drew significant interest from the aviation community and as a result the award process was highly competitive,” said Nateri Madavan, director for NASA’s Advanced Air Vehicles Program. “The proposals selected come from a diverse set of organizations that will provide exciting and wide-ranging explorations of the scenarios, technologies, and aircraft concepts that will advance aviation towards its transformative sustainability goals.” An artist’s concept of JetZero’s blended wing body, which the company’s team will use to evaluate technologies for the NASA Advanced Aircraft Concepts for Environmental Sustainability 2050 initiative.

NASA expects the awardees to complete their studies by mid-2026. The new awardee institutions are: Aurora Flight Sciences, a Boeing Company, whose team will perform a comprehensive, “open-aperture” exploration of technologies and aircraft concepts for the 2050 timeframe. This will include examining new alternative aviation fuels, propulsion systems, aerodynamic technologies, and aircraft configurations along with other technology areas that arise throughout the study. The Electra-led team will explore extending Electra’s novel distributed electric propulsion and its unique aerodynamic design capabilities to develop innovative wing and fuselage integrations that deliver sustainable aviation focused on enabling community-friendly emission reduction, noise reduction, and improved air travel access. The company’s existing small aircraft prototype has been flying for over a year, demonstrating Electra’s technology that aims to transform air travel with reduced environmental impact and improved operational efficiency. Georgia Institute of Technology will perform a comprehensive exploration of sustainability technologies, including alternative fuels, propulsion systems, and aircraft configurations. The institute’s team will then explore new aircraft concepts incorporating the selected technologies with their Advanced Technology Hydrogen Electric Novel Aircraft (ATH2ENA) as a starting point. JetZero will explore technologies that enable cryogenic, liquid hydrogen to be used as a fuel for commercial aviation to reduce greenhouse gas emissions. These technologies will be evaluated on both tube-and wing and JetZero’s blended wing body – an airplane shape that provides more options for larger hydrogen fuel tanks within the aircraft. Pratt and Whitney a division of RTX Corporation, will explore a broad suite of commercial aviation propulsion technologies targeting thermal and propulsive efficiency improvements to reduce fuel consumption and greenhouse gas emissions. The Pratt & Whitney team will then down-select high-priority and alternative propulsion concepts for potential integration studies with various airframe concepts for aircraft in 2050 and beyond.

Name: Matthew Kowalewski Title: Dragonfly Mass Spectrometer (DraMS) Lead Instrument Systems Engineer Formal Job Classification: Aerospace Engineer Organization: Instrument and Payload Systems Engineering Branch (Code 592) Matthew Kowalewski is the lead instrument systems engineer for NASA’s Dragonfly Mass Spectrometer (DraMS). Photo courtesy of Matthew Kowalewski What do you do and what is most interesting about your role here at Goddard? As the DraMS lead instrument systems engineer for NASA’s Dragonfly mission, I lead the coordinated technical development, integrating systems and making sure communications across subsystems is maintained within the instruments as well as with the lander. I enjoy the diversity and complexity of this instrument. What do you enjoy most about your current position as the DraMS lead instrument systems engineer? I started this position in March 2023 and it has been like drinking from a fire hose ever since, but in a good way. The complexity of the instrument and the number of subsystems means this is really three separate instruments in one, and that makes my job exciting. I have to keep up with a range of disciplines across everything that Goddard does including mechanisms, lasers, mass spectrometers, gas flow systems, mechanical systems, thermal systems and electrical systems. I am always challenged and excited by those challenges too. Everything we do is necessary to meet the broad science requirements. Our goal is studying prebiotic chemistry on the surface of Titan. What is your educational background? Why did you become an aerospace engineer? I have a B.A. in astronomy and physics from Boston University and a master’s in physics from Johns Hopkins University. As a child, I was more interested in astronomy and physics. In college, I developed an extreme interest in experimental physics including the engineering required to perform these experiments. How did you come to Goddard? After college, I worked in missile defense for a private company supporting the Midcourse Space Experiment. After three years, in 1998, my wife and I wanted to move closer to family, so I came to Goddard as an instrument engineer supporting the Total Ozone Mapping Spectrometer-Earth Probe (TOMS/EP) mission. I have also supported the Ozone Monitoring Instrument on Aura, The Ozone Mapping Profiler Suite (OMPS) on Suomi NPP and JPSS, various airborne field campaigns, and the New Opportunities Office. What interesting field work did you do prior to joining DraMS? I largely did field work supporting Earth science research and new business development. We flew remote sensing instruments on high altitude aircraft in the United States, Costa Rica, South Korea [whose official name is the Republic of Korea], and Canada. Most field campaigns lasted about a month where we were housed in hotels or military bases. While supporting the New Opportunities Office, we developed instrument and mission concepts, evaluated and prioritized technologies, and fostered relationships with industry, universities, and other government organizations. How do you lead across multiple teams? I lead a large team engineers and technicians spanning across over six teams. Communication is the key. I rely on the expertise of our systems team and all of the subsystem leads. We have daily and weekly meetings where everyone is heard and they are free to approach me whenever they have concerns. I try to encourage open discussions including contrarian thoughts and ideas. I listen to all the options and opinions in an attempt to make the best-informed decision. Then I move forward with my decision. In a cost- and schedule-constrained environment, like most missions are, we cannot get stuck in the decision-making process. At some point, a decision needs to be made and the team then moves forward. Where have you traveled for work? I have been to multiple NASA centers and military bases in this country. In addition to Costa Rica, South Korea and Canada, I have also been to the Netherlands and France for mission development. What is the most memorable moment you have had at Goddard? In 2003, I was supporting the space shuttle Columbia mission, STS-107. We had a small payload in the shuttle cargo bay called a Hitchhiker. I was second shift in the Hitchhiker mission operations center. I got to interact with the astronauts both prelaunch and on orbit. It meant a lot to me. My last shift was just prior to their reentry. It really impacted me when I learned, after my shift, that the shuttle disintegrated with all hands lost. I had the honor of meeting these astronauts. It reminded me of the importance of the work that we do as we continue sending astronauts into orbit for missions. When you mentor someone, what do you advise them to do? I tell them to learn as much about everything that they can. For example, if they are an engineer, they should learn about science and other disciplines because a broad knowledge base will help them in the future. They will also learn why building a small piece of hardware is important for accomplishing the mission’s science goals. An electrical engineer building a circuit is actually building something for a far larger purpose. It is also very important to get along with others. We work with others every day, in all aspects of our lives, and we have to understand their perspectives and respect their opinions. There is more to our jobs than building things. Establishing relationships with others is what truly allows us to accomplish our goals. What do you do for fun? I have four kids and enjoy spending time with them. I coach soccer, mentor a robotics club, and participate in endurance swim races. This is my second year as a mentor to my son’s robotics club, which participates in an annual, national robotics competition to build a robot from scratch. This year we have a highly mobile, fast robot with a multi-jointed arm to manipulate objects. I think we have a good shot at going to nationals. Who would you like to thank? I wish to thank my wife Angie for supporting me over all these years as my career developed. She was often home alone with four kids during long stints of travel. I would not be where I am without her. I also owe much to my mentors, Scott Janz, Glenn Jaross, and Jay Al-Saadi for all their guidance, support and opportunities over the many years. Nobody can work alone, no matter how smart you are. What is your “five-word or phrase memoir”? A five-word or phrase memoir describes something in just five words or phrases. Understanding. Compassionate. Persistent. Hard-working. Curious about too many things. By Elizabeth M. Jarrell NASA’s Goddard Space Flight Center, Greenbelt, Md.

Name: Dr. Inia Soto Ramos Title and Formal Job Classification: Associate Research Scientist Organization: Ocean Ecology Laboratory (Code 616) via Morgan State University and GESTAR II cooperative agreement Dr. Inia Soto Ramos is an associate research scientist with NASA’s PACE — the Plankton, Aerosol, Cloud, ocean Ecosystem mission — at the agency’s Goddard Space Flight Center in Greenbelt, Md.Photo courtesy of Inia Soto Ramos What do you do and what is most interesting about your role here at Goddard? I am currently co-leading the validation efforts for PACE, NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem mission. I am also part of NASA’s SeaBASS (SeaWiFS Bio-optical Archive and Storage System) team, which is responsible for archiving, distributing, and managing field data used for validation and development of satellite ocean color data products. It has been exciting to be a part of a satellite mission, to see it being built, tested and launched. And now, be able to validate the data and in the near future, use the data to do science. What is your educational background? I graduated with a bachelor’s degree in biology from The University of Puerto Rico, Mayagüez Campus, and I have a master’s and Ph.D. in Biological Oceanography from the University of South Florida. How did you get your foot in the door at NASA? While I was a student at the University of Puerto Rico, I saw a flyer for a program called PaSCoR (Partnership for Spatial and Computational Research). It was a partnership between universities, NASA and other institutions with the intent to train students in remote sensing and Geographical Information Systems. Although, this program was targeted mainly for engineers, I decided to apply. That took me to the first remote sensing classes I had taken. That’s how I started learning that you can study the ocean from space. I had no idea that could be done. That program planted the curiosity about satellite oceanography and gave me the tools to go into graduate school in that field. How did you first gain exposure to oceanography and diving? I am from Puerto Rico and grew up all the way in the mountains. There wasn’t much of a connection to the ocean for me, only a few trips to the beach. I remember my dad taking me to a small beach called La Poza del Obispo in Arecibo and he held me while I used a small snorkel underwater. That was the first connection I had with marine life. I started diving sometime when I was about 18 years old, and I remember saying, “This is the most amazing thing ever,” and that’s when I decided I needed to pursue a life in that field. What interested you in phytoplankton as a specialty? Initially, I was curious about harmful algal blooms in the West Florida Shelf, which I studied when I moved to Florida to do my grad studies. I learned that the blooms can produce neurotoxins, and those can affect humans in different ways. So, if you have asthma, they can make you feel worse. I remember developing asthma that night after going to the beach and having go to the ER. I didn’t see the connection at the time until I learned about these events and how toxins can get in the air. It felt like something important that I could study to help people or do something that’s meaningful. It’s amazing that we can see something so tiny from space and study them. How does your identity, being a Latina, show up at NASA? This is kind of a dream come true. It is so amazing to be able to fulfill that dream. I came from a small town. There appeared to me no chances to come all the way to NASA. So, having this opportunity is exciting, and bringing it back to my community and saying, “Hey, anyone can actually do it.” One of the advantages is that you speak a different language, so you can make connections with different countries. What do you look forward to in the future? What are some of your goals? I would love to keep growing in my field. As a mother, sometimes is hard to visualize where I want to be in the future, so I find it best to focus on the present. My priority right now is my family, however in the future I would love to engage in a job in which I can transfer my knowledge and love to the oceans to future generations; and be more involved in the community. When you think of your village and growing up in Puerto Rico, what is a memory you have that makes you smile? I still remember going to collect coffee with my mom and dad. My dad had a small basket for me that I would fill with only the most beautiful red grains of coffee. I was around 5 years old, and I remember the toys that my mom would take, and they’d settle me under the coffee trees. I still go to Puerto Rico, and I am fascinated when I see the coffee trees; it reminds me of my childhood. What advice would you give to other little girls who might not think NASA is a dream they can achieve? I was the little girl with the dream of being a scientist at NASA, and then I was a teenager, an adult, and a mother, all with the same dream! It took me several decades and many life stages to get here. Many times, along my path, I thought of giving up. Others, I thought I was completely off track and I would never fulfill my dream. I had limited resources while growing up. There were no fancy swimming or piano classes, but I had amazing teachers and mentors who guided me along the way. So, no matter how young or old you are, you can still fulfill that dream. The key to success is to know where you want to go, surround yourself with people that believe in you, and if you fall, just shake it off and try again!

The camera is located high on the rover’s mast and aids in driving. The image was acquired on Oct. 27, 2024 (Sol 1311) at the local mean solar time of 16:02:45. NASA/JPL-Caltech Perseverance acquired this image of a possible breccia outcrop on the Jezero crater rim using its Left Mastcam-Z camera. Mastcam-Z is a pair of cameras located high on the rover’s mast. This image was acquired on Oct. 27, 2024 (Sol 1311) at the local mean solar time of 12:52:58. NASA/JPL-Caltech/ASU During its recent exploration of the crater rim, Perseverance diverted to explore a strange, scattered field of bright white rocks which sparked the interest of the team scientists. Perseverance has been climbing up the steep slopes of the Jezero crater rim for over two months now, and ever since approaching the edge of the crater has been spying increasingly diverse and strange-looking rocks. Back in the Jezero inlet channel, Neretva Vallis, Perseverance spotted a whole host of colourful boulders at Mount Washburn, and more recently the science team and internet alike were mesmerised by Freya Castle – a rock striped like a zebra! The crater rim hasn’t finished delivering surprises yet though… Just as we humans were preparing for Halloween back on Earth, a ghostly field of bright white rocks appeared in Perseverance’s view, at the base of a mound in the crater rim termed “Mist Park”, and sparking a new mystery for the science team to unravel. On Earth, we find white rocks in a wide array of geologic settings, and that’s not surprising given the diverse array of light-toned minerals which can be generated across Earth’s various tectonic settings. On Mars however, with its lack of plate tectonics and a basaltic crust dominated by dark minerals like olivine and pyroxene, white rocks are a rare find. The science team planned several observations using Perseverance’s remote sensing instruments to assess the composition of these peculiar pebbles, including multispectral imaging with Mastcam-Z and zapping them with Supercam’s laser. Hopefully these observations can shed light on how these white rocks formed all the way up here on the crater rim. Unfortunately, none of the rocks were big enough to safely inspect them up close with Perseverance’s robotic arm instruments, but the team are on the lookout for larger blocks or outcrops of this strange lithology as we continue traversing upslope. Aside from their composition, another mystery is just how these rocks got here. The blocks are all float (float = loose rocks, not in their original location), and scattered over just a few square meters. Perhaps these could be erosional leftovers of some kind of resistant vein or rock layer, where the softer, surrounding lithologies have eroded away? Or could these blocks have tumbled downslope from a more continuous bedrock exposure of enigmatic white material? Who knows, but Perseverance will be keeping its eyes peeled for more of these bizarre blocks as it continues to summit new heights… Written by Alex Jones, PhD student at Imperial College London Downloads Perseverance Raw Images Mars Perseverance Sol 1311: Right Navigation Camera (Navcam) Nov 12, 2024 PNG () Mars Perseverance Sol 1311: Left Mastcam-Z Camera Nov 12, 2024 PNG () Share Details Last Updated Nov 12, 2024 Related Terms Blogs Explore More 2 min read Sols 4359-4361: The Perfect Road Trip Destination For Any Rover!

A Mangrove stand lines the bank of Shark River, an Everglades distributary that carries water into the Gulf of Mexico’s Ponce De Leon Bay. Photo credit: Nathan Marder/NASA’s Goddard Space Flight Center (GSFC) Introduction Along the southernmost rim of the Florida Peninsula, the arching prop roots or “knees” of red mangroves (Rhizophora mangle) line the coast – see Photo 1. Where they dip below the water’s surface, fish lay their eggs, enjoying the protection from predators that the trees provide. Among their branches, wading birds, such as the great blue heron and the roseate spoonbill establish rookeries to rear their young. The tangled matrix of roots collects organic matter and ocean-bound sediments, adding little-by-little to the coastline and shielding inland biology from the erosive force of the sea. In these ways, mangroves are equal parts products and engineers of their environment, but their ecological value extends far beyond this local sphere of influence. Mangroves are an important carbon dioxide (CO2) sink – responsible for removing CO2 from the atmosphere with impressive efficiency. Current estimates suggest mangroves sequester CO2 10 times faster and store up to 5 times more carbon than rainforests and old-growth forests. But as part of the ever-changing line between land and sea, they’re exceptionally vulnerable to climate disturbances such as sea level rise, hurricanes, and changes in ocean salinity. As these threats intensify, Florida’s sub-tropical wetlands – and their role as a critical sink of CO2 – face an uncertain future. NASA’s BlueFlux Campaign, a three-year (2021–2024), $1.5-million project operating under the agency’s Carbon Monitoring System, used field, aircraft, and satellite data to study the impact of both natural and anthropogenic pressures on South Florida’s coastal ecology. BlueFlux consists of a series of ground-based and airborne fieldwork campaigns, providing a framework for the development of a satellite-based data product that will estimate daily rates of surface-atmosphere gas transfer or gaseous flux across coastal ecosystems in Florida and the Caribbean. “The goal is to enhance our understanding of how blue-carbon ecosystems fit into the global carbon market,” said Ben Poulter [NASA’s Goddard Space Flight Center (GSFC)—Project Lead]. “BlueFlux will ultimately answer scientific questions and provide policy-related solutions on the role that coastal wetlands play in reducing atmospheric greenhouse gas (GHG) concentrations.” This article provides an overview of BlueFlux fieldwork operations – see Figure 1 – and outlines how the project might help refine global GHG budgets and support the restoration of Florida’s wetland ecology. Figure 1. A map of South Florida overlaying a true-color image captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on board NASA’s Terra satellite. Red triangles mark locations of primary ground-based fieldwork operations described in this article. Figure Credit: NASA’s Goddard Space Flight Center (GSFC) BlueFlux Ground-based Fieldwork Across the street from the Flamingo Visitors center, at the base of the Everglades National Park, there was once a thriving mangrove population. Now, the skeletal remains of the trees form one of the Everglades’ largest ghost forests – see Photo 2. When Hurricane Irma made landfall in September 2017, violent winds battered the shore and a storm surge swept across the coast, decimating large swaths of the mangrove forest. Most of Florida’s mangroves recovered swiftly. But seven years later, this site and others like it have seen little to no growth. “At this point, I doubt they’ll ever recover,” said David Lagomasino [East Carolina University]. Photo 2. A mangrove ghost forest is all that remains of a once-thriving mangrove stand, preserving an image of Hurricane Irma’s lasting impact on South Florida’s wetland ecology. Most of the ghost forests in the region are a product of natural depressions in the landscape that collect saltwater following severe storms. Photo credit: Nathan Marder/NASA’s Goddard Space Flight Center (GSFC) Lagomasino was in the Everglades this summer conducting research as part of the fifth leg of BlueFlux fieldwork – see Photo 3. His team focused on measuring how changes in wetland ecology affect the sequestration and emission rates of both CO2 and methane (CH4). In areas where vegetative health is severely degraded, like in ghost forests, a general decline in CO2 uptake is accompanied by an increase in CH4 production, the net effect of which could dramatically amplify the atmosphere’s ability to trap heat. Ghost forests offer an example at one end of an extreme, but defining the way more subtle gradients among wetland variables – such as changes in water level, tree height, canopy coverage, ocean salinity, or mangrove species distribution – might influence flux is harder to tease out of the limited data available. Photo 3. Assistant professor David Lagomasino and Ph.D. candidate Daystar Babanawo [both from East Carolina University] explore the lower Everglades by boat. Due to the relative inaccessibility of the region, measurements of flux in wetland ecosystems are limited. The plant life here consists almost entirely of Florida’s three Mangrove species (red, black, and white), which are among the only vegetation that can withstand the brackish waters characteristic of coastal wetlands. Photo credit: Nathan Marder/NASA’s Goddard Space Flight Center (GSFC) In the Everglades, flux measurements are confined to a handful of eddy covariance towers – or flux towers – constructed as part of the National Science Foundation’s (NSF) Long-Term Ecological Research (LTER) Network. The first flux tower in this network, erected in June 2003, stands near the edge of Shark River at a research site called SRS-6, short for Shark River Slough site 6. A short walk from the riverbank, across a snaking path of rain-weathered, wooden planks, sits a small platform where the flux tower is anchored to the forest floor – see Photo 4. About 20 m (65 feet) above the platform, the tower breaches the canopy, where a suite of instruments continuously measures wind velocity, temperature, humidity, and the vertical movement of trace atmospheric gases, such as water vapor (H2Ov), CO2, and CH4. It’s these measurements collectively that are used to calculate flux. Photo 4. At SRS-6, an eddy covariance tower measures C02 and CH4 flux among a dense grove of red, black, and white mangroves. The term eddy covariance refers to the statistical technique used to calculate gaseous flux based on the meteorological and scalar atmospheric data collected by the flux towers. Photo credit: Nathan Marder/NASA’s Goddard Space Flight Center (GSFC) “Hundreds of research papers have come from this site,” said Lagomasino. The abundance of research generated from the data captured at SRS-6 speaks in part to the value of the measurements that the tower makes. It also points to the gaps that exist just beyond each tower’s reach. A significant goal of the BlueFlux campaign is to explain flux on a scale that isn’t covered by existing data – to fill in the gaps between the towers. One way to do that is by gathering data by hand. On Lagomasino’s boat is a broad, black case carrying a tool called a Russian peat auger. The instrument is designed to extract core samples from soft soils – see Photo 5. Everglades peat, which is made almost entirely of the partially decomposed roots, stems, and leaves of the surrounding mangroves, offers a perfect study subject. Each thin, half-cylinder sample gets sealed and shipped back to the lab, where it will be sliced into flat discs. The discs will be analyzed for their age and carbon content by Lagomasino’s team and partners at Yale University. These cores are like biomass time capsules. In Florida’s mangrove forests, a 1-m (3-ft) core might represent more than 300 years of carbon accumulation. On average, a 1 to 3 mm (0.04 to 0.12 in) layer of matter is added to the forest floor each year, building up over time like sand filling an hourglass. Photo 5. David Lagomasino holds a Russian peat auger containing a sample of Everglades peat. The primary source of the soil’s elevated carbon content – evident from its coarse, fibrous texture – is the partially decayed plant tissue of the surrounding mangroves. Photo credit: Nathan Marder/NASA’s Goddard Space Flight Center (GSFC) Although coastal wetlands account for less than 2% of the planet’s land-surface area, they house a disproportionate amount of blue carbon – carbon stored in marine and coastal environments. In the Everglades, the source of this immense accumulation of organic material is the quick-growing vegetation – see Photo 6. When a CO2 molecule finds its way through one of the many small, porous openings on a mangrove leaf ­– called stomata – its next step is one of creation, where it plays a part in the miraculous transformation of inorganic matter into living tissue. Inside the leaf’s chloroplasts, energy from stored sunlight kickstarts a long chain of chemical reactions that will ultimately divide CO2 into its constituent parts. Oxygen atoms are returned to the atmosphere as the byproduct of photosynthesis, but the carbon stays behind to help build the sugar molecules that will fuel new plant growth. In short, the same carbon that once flowed through the atmosphere defines the molecular structure of all wetland vegetation. When a plant dies or a gust of wind pulls a leaf to the forest floor, this carbon-based matter finds its way into the soil, where it can stay locked in place for thousands of years thanks to a critical wetland ingredient: water. The inundated, anoxic – an environment deficient or absent of oxygen – peat soils characteristic of wetlands host microbial populations that are uniquely adapted to their environment. In these low- to no-oxygen conditions, the prevailing microbiota consumes organic material slowly, leading to an accumulation of carbon in the soil. As wetland conditions change, the soil’s microbial balance shifts. For example, a decline in water level, which can increase the oxygen-content of the soil, produces conditions favorable to aerobic bacteria. These oxygen-breathing lifeforms consume organic matter far more rapidly than their anaerobic counterparts – and release more CO2 into the atmosphere as a result. Water level isn’t the only environmental condition that influences rates of carbon sequestration. The soil cores collected during the campaign will be analyzed alongside records of interrelated variables such as water salinity, sea surface height, and temperature to understand not just the timescales associated with blue carbon development in mangrove forests but how and why rates of soil deposition change in response to specific environmental pressures. In many parts of the Everglades, accumulated peat can reach depths of up to 3 m (9.8 feet) – holding thousands of years’ worth of insights that would otherwise be lost to time. Photo 6. Mangroves are viviparous plants. Their propagules – or seedlings – germinate while still attached to their parent tree. Propagules that fall to the forest floor are primed to begin life as soon as they hit the ground. But even those that fall into bodies of water and are carried out to sea can float for months before finding a suitable place to lay their roots. The high growth rate of mangroves contributes to the efficiency with which mangrove forests remove CO2 from the atmosphere. Photo credit: Nathan Marder/NASA’s Goddard Space Flight Center (GSFC) Lola Fatoyinbo [NASA’s Goddard Space Flight Center (GSFC), Biospheric Sciences Lab] and Peter Raymond [Yale University’s School of the Environment] led additional fieldwork teams tasked with collecting forest inventory data in locations where vegetation was dead, regenerating, or recently disturbed by severe weather events. A terrestrial laser system was used to obtain three-dimensional (3D) images of mangrove forest structure, which provided maps of stem density, vertical distributions of biomass, and stand volume surface area. Spectroradiometers were also used to acquire visible, near infrared, and shortwave infrared spectra, delivering detailed information about species composition, vegetative health, water levels, and soil properties. To tie these variables to flux, the researchers made measurements using chambers – see Figure 2 – designed to adhere neatly to points where significant rates of gas exchange occur, (i.e., mangrove lenticels—cell-sized breathing pores found on tree bark and root systems— and the forest floor). As an example, black mangroves (Avicennia germinans) possess unique aerial roots called pneumatophores that, similar to the prop roots of red mangroves, provide them with access to atmospheric oxygen. Pneumatophores sprout vertically from the forest floor and line up like matchsticks around the base of each tree. The team used cylindrical chambers to measure the transfer of gas between a single pneumatophore and the atmosphere – see Figure 2a. These observations are archived in NASA’s Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC) and publicly available to researchers who wish to monitor and identify trends in the data. After nearly three years of field work, these data have already given scientists a more detailed picture of how Florida’s wetlands are responding to environmental pressures. Research based on data from early BlueFlux fieldwork deployments confirms that aerobic, methanogenic microbes living in flooded, wetland soils naturally release a significant amount of CH4 as a byproduct of the process by which they create their own energy. “We’re especially interested in this methane part,” said Fatoyinbo. “It’s the least understood, and there’s a lot more of it than we previously thought.” Fatoyinbo also noted a “significant difference in CO2 and CH4 fluxes between healthy mangroves and degraded ones.” In areas where mangrove health is in decline, due to reduced freshwater levels or as the result of damage sustained during severe weather events, “you can end up with more ‘bad’ gases in the atmosphere,” she said. Since CH4 is roughly 80 times more potent than CO2 over 100-year period, these emissions can undermine some of the net benefits that blue carbon ecosystems provide as a sink of atmospheric carbon. Figure 2. To directly measure the emission and sequestration rates of CO2 and CH4 in mangrove forests, chambers were designed to adhere to specific targets where gas exchange occurs (i.e. mangrove lenticles, root systems, and the forest floor).

Even with over 20 years of tower data and the extensive measurements from ground-based fieldwork operations, making comprehensive inferences about the entire ecosystem is tenuous work. To provide flux data at scale – and help quantify the atmospheric influence that Florida’s coastal wetlands carry as a whole – NASA’s BlueFlux campaign relies on a relatively new, airborne technique for measuring flux – see Photo 7. Photo 7. At the Miami Executive Airfield, members of NASA’s BlueFlux airborne science team stand in front of the Beechcraft 200 King Air before the final flight of the fieldwork campaign. Photo credit: Nathan Marder/NASA’s Goddard Space Flight Center (GSFC) Between 2022 and 2024, over 5 deployments, the team conducted more than 34 carefully planned flights – see Figure 3 – collecting flux data over Florida’s wetlands by plane. Each flight is equipped with a payload known colloquially as “CARAFE,” short for the CARbon Airborne Flux Experiment, which is the airborne campaign’s primary means of data collection. “This is one of the first times an instrument like this has flown over a mangrove forest anywhere in the world,” said Fatoyinbo. “So, it’s really just kind of groundbreaking.” Figure 3. An example of flight paths from eight BlueFlux airborne deployments flown in April 2023. The flight paths are highlighted in blue. The legs of each flight where flux measurements were taken are highlighted in green. Accurate flux calculations rely on stable measurements of the aircraft’s speed and orientation, which is why the flux legs of each flight are flown in straight lines. Credit: GSFC In the air, GHG concentrations are measured using a well-established technique called cavity ringdown spectroscopy, which involves firing a laser into a small cavity where it will ping back and forth between two highly reflective mirrors. Most gas-phase molecules absorb light at specific wavelengths, depending on their atomic makeup. Since the target molecules in this case are CO2 and CH4, the laser is configured to emit light at a wavelength that only these molecules will absorb. As the laser bounces between the mirrors, a fraction of the light is absorbed by any molecules present in the chamber. The rate of the light’s decay is used to estimate CO2 and CH4 concentrations, generating a time series with continuous readings of gas concentrations, measured in parts per million – see Photo 8. This information is combined with measurements of vertical wind velocity to calculate a corresponding time series of fluxes along the flight track. While these measurements are important on their own, a priority for the airborne team is understanding GHG fluxes in relation to what’s happening on the ground. Photo 8. The CARAFE payload is responsible for taking readings of atmospheric CO2, CH4, and H2Ov levels using a wind probe and two optical spectroscopy instruments manufactured by Picarro: the G2401m Gas Concentration Analyzer and the G2311f Gas Concentration Analyzer. The readings pictured above were made by the G2311f, which measures gas concentrations at a faster rate than the G2401m. The G2401m makes slower but more stable measurements, which are necessary for verifying the accuracy of measurements made by the G2311f. Photo credit: Nathan Marder/NASA’s Goddard Space Flight Center (GSFC) Unlike flux towers, which only collect data within a 100 m2 (328 ft2) “footprint,” airborne readings have a footprint that can stretch up to 1 km (0.6 mi) in upwind directions. The plane’s speed, position, and orientation are used to help link flux data to fixed points along the flight’s path – so the team can make comparisons between aerial measurements and those made by the ground-based towers – see Photo 9. “One challenge with that is the flux towers are much lower to the ground, and their footprint is much smaller,” said Glenn Wolfe [GSFC—BlueFlux Flight Lead]. “So, we have to be really careful with our airborne observations, to make sure they closely resemble our ground-based measurements.” Part of decoding the airborne data involves overlaying each footprint with detailed maps of different surface properties, such as vegetation cover, soil water depth, or leaf-area index, so the team can constrain the measurements and assign fluxes to specific sources – whether its mangroves, sawgrass, or even water. Photo 9. The BlueFlux airborne science team collects flux measurements from 90m (300ft) above Florida’s mangrove forests. Photo credit: Nathan Marder/NASA’s Goddard Space Flight Center (GSFC) Data Upscaling – Making Daily Flux Predictions from Space The coupling of BlueFlux’s ground-based and airborne data provides the framework for the production of a broader, regional image of GHG flux. “The eddy flux towers give us information about the temporal variability,” said Cheryl Doughty [GSFC]. “And the airborne campaign gives us this great intermediate dataset that allows us to go from individual trees to a much larger area.” Doughty is now using BlueFlux data to train a remote-sensing data product, the prototype of which is called Daily Flux Predictions for South Florida. The product’s underlying model relies on machine learning algorithms and an ensemble modeling technique called random forest regression. It will make flux predictions based on surface reflectance data captured by the Moderate Resolution Imaging Spectroradiometer (MODIS), an instrument that flies on NASA’s polar-orbiting Aqua and Terra satellites – see Figure 4. “We’re really at the mercy of the data that’s out there,” said Doughty. “One of the things we’re trying to produce as part of this project is a daily archive of fluxes, so MODIS is an amazing resource, because it has over 20 years of data at a daily temporal resolution.” This archival flux data will help researchers explain how fluxes change in relation to processes that are directly described by MODIS surface reflectance data, including sea-level rise, land use, water management, and disturbances from hurricanes and fires. Figure 4. Sample of methane flux upscaling, in which MODIS surface reflectance retrievals are used to predict CH4 flux for South Florida at a regional scale [bottom row, left]. The model inputs rely on a composite of MODIS Nadir Bidirectional Reflectance Distribution Function (BRDF)-Adjusted Radiance (NBAR) measurements from all available MODIS land bands: [top row, left to right]: red (620–670 nm), green (545–565 nm), blue (459–479 nm); [middle row, left to right] near infrared 1, or NIR1 (841–876 nm), NIR2 (1230–1250 nm), shortwave IR 1, or SWIR1 (1628–1652 nm), and SWIR 2 (2105–2155 nm). The Everglades National Park boundary is indicated on each image with a white line. Output of the model is shown [bottom row, left] as well as a comparison between modeled fluxes of MODIS NBAR with Terra and Aqua [bottom row, right]. Credit: GSFC To help validate the model, researchers must reformat flux measurements from the airborne campaign to match the daily temporal resolution and 500m2 (0.3mi2) spatial resolution of MODIS reflectance retrievals. “It’s best practice to meet the data at the coarsest resolution,” said Doughty. “So, we have to take an average of the hourly estimates to match MODIS’ daily scale.” The matching process is slightly more complicated for spatial datasets. BlueFlux’s airborne flux measurements produce roughly 20 data points for each 500 m2 (0.3 mi2) area, the same resolution as a single MODIS pixel. “We’re essentially taking an average of all those CARAFE points to get an estimate that corresponds to one pixel,” said Doughty. This symmetry is critical, allowing the team to test, train, and tune the model using measurements that capture what’s really happening on the ground – ensuring the accuracy of flux measurements generated from satellite data alone. Researchers don’t expect the model to serve as a perfect reconstruction of reality. The heterogenous nature of Florida’s wetland terrain – which consists of a patchwork of sawgrass marshland, mangrove forests, hardwood hammocks, and freshwater swamps – contributes to high degree of variability in CO2 removal rates within and across its distinct regions. The daily flux product accounts for some of this complexity by making hundreds of calculations at a time, each with slightly different parameters based on in-situ measurements. “The goal isn’t to just give people one flux measurement but an estimate of the uncertainty that is so inherent to these wetlands,” explained Doughty. The prototype of the product will be operational by early 2025 and accessible to the public through NASA’s ORNL­ DAAC. Doughty hopes it will help stakeholders and decision makers evaluate policies related to water management, land use, and conservation that might impact critical stocks of blue carbon. From Drainage to Restoration in the Florida Everglades In the late 19th century, land developers were drawn to South Florida, where they hoped the fertile soil and tropical climate could support year-round cultivation of commodities such as exotic fruits, vegetables, and sugar cane. There was just one thing standing in the way – the water. If they could find a way to tame Florida’s wilderness, to drain the wetland of its excess water, Florida would offer Americans a new agricultural frontier. Progress was made incrementally, but the Everglades drainage project idled for more than 50 years as its organizers wrestled with the literal and political morass surrounding South Florida’s wetland topography. It was mother nature’s hand that ultimately accelerated the drainage project. In 1926 and 1928, two large hurricanes tore through the barrier along Lake Okeechobee’s southern shore built to prevent water from spilling onto the newly settled, small-scale farmland just south of the lake. The second of the two storms – 1928’s Okeechobee Hurricane – made landfall in early September and resulted in nearly 3,000 recorded fatalities. In some areas, the torrent of flood water was deep enough that even those who sought refuge from the flood on the roofs of their homes were swept away by the current. The federal government was forced to step in. By 1938, the U.S. Army Corps of Engineers had completed construction of the Hoover Dike, adding to a collection of four canals responsible for siphoning water away from Lake Okeechobee’s floodplain and into the Atlantic Ocean. Seasonal flooding was brought under control, but the complete reclamation of South Florida’s wetlands proved more challenging than anticipated. As water levels fell and freshly cleared lands dried out, the high organic content of the soil fueled tremendous peat and muck fires that could burn for days, spreading through underground seams where water once flowed. In some areas, fires consumed the entire topsoil layer – exposing the limestone substrata to the atmosphere for the first time in thousands of years. The engineers in charge of Florida’s early wetland reclamation projects underestimated the value of the state’s hydrological system and overestimated its capacity to withstand human interference. “Those initial four canals were enough to drain the everglades three times over,” said Fred Sklar [South Florida Water Management District—Everglades System Sciences Director]. “And they still exist, but now there are more than seven million people who rely on them for drinking water and flood control.” Today, much of the Water Management District’s work involves unwinding the damage wrought by earlier drainage efforts. “One thing we’re trying to do is make sure these peat fires never happen again,” said Sklar. But restoring natural water flow to the Everglades ­– which is critical to the region’s ecological health – isn’t an option. Even if drainage could be reversed, it would subject Florida’s residents to the same flood risks that made drainage a priority. Some residents, including members of the Miccosukee and Seminole tribes, live directly alongside or within Everglades wilderness areas, where the risk of flooding is even greater than it is in the state’s highly populated coastal communities. These areas are also out of reach of the Water Management District’s existing infrastructure. It’s not as simple as turning the tap on and off. Photo 10. The Tamiami Trail Canal runs across the Florida Peninsula from west to east, towards a saltwater treatment facility near the Miami River. Construction was completed in 1928, shortly after the first four drainage canals opened. It quickly became apparent that the canal and its adjacent roadway dramatically impede water flow to the Everglades wilderness areas to their south, cutting off the region’s vegetation and wildlife from a critical source of freshwater. New modifications to the canal are currently underway, which aim to introduce a hydrological regime that more closely resembles the pre-drainage system. Photo credit: U.S. National Park Service Florida’s Water Management District works with federal agencies, including the U.S. Army Corps of Engineers, to monitor and govern the flow of Florida’s freshwater. The District has overseen the construction and management of dozens of canals, dikes, levees, dredges, and pumps over the last half-century that offer a higher degree of control over Florida’s complex hydrological network – see Photo 10. “The goal is to restore as much acreage as we can, but we also need to restore it functionally, without degrading the whole system or putting residents at risk,” summarized Sklar. “To do this effectively, we need a detailed understanding of how the hydrology functions and how it influences all of these other systems, such as carbon sequestration.” Since the 1920s, more than half of Florida’s original wetland coverage has been lost. The present system also carries 65% less peat coverage and 77% less stored carbon than it did prior to drainage. As atmospheric CO2 concentrations climb at unprecedented rates, an accompanying rise in sea levels, severe weather, and ocean salinity all present serious threats to Florida’s wetland ecology – see Figure 5. “We’re worried about losing that stored carbon,” said Poulter. “But blue carbon also offers tremendous opportunities for climate mitigation if conservation and restoration are properly supported by science.” Figure 5. A map of the BlueFlux study region, showing mangrove extent (green) and the paths of tropical storms and hurricanes from 2011 to 2021 (red). These storms drive losses in mangrove forest coverage – the result of erosion and wind damage. The inset regions at the top of the image highlight proposed targets for the airborne component of NASA’s BlueFlux Campaign. Figure credit: GSFC Conclusion – The Future of Flux Every few years, the Intergovernmental Panel on Climate Change (IPCC) releases emissions data and budget reports that have important policy implications related to the Paris Agreement’s goal of limiting global warming to between 1.5°C (2.7°F) and 2°C (3.6°F) compared to pre-industrial levels. Refining the accuracy of global carbon budgets is paramount to reaching that goal, and wetland ecosystems – which have been historically under-represented in climate research – are an important part of the equation. Early estimates based on BlueFlux fieldwork deployments and upscaled using MODIS surface reflectance data suggest that wetland CH4 emissions in South Florida offset CO2 removal in the region by about 5% based on a 100-year CH4 warming potential, resulting in a net annual CO2 removal of 31.8 Tg (3.18 million metric tons) per year. This is a small fraction of total CO2 emissions in the U.S. and an even smaller fraction of global emissions. In 2023, an estimated 34,800 Tg (34.8 billion metric tons) of CO2 were released into the atmosphere. But relative to their size, the CO2 removal services provided by tropical wetlands are hardly dismissible. “We’re finding that massive amounts of CO2 are removed and substantial amounts of CH4 are produced, but overall, these ecosystems provide a net climate benefit by removing more greenhouse gases than they produce,” Poulter said. Access to a daily satellite data product also provides researchers with the means to make more regular adjustments to budgets based on how Florida’s mutable landscape is responding to climate disturbances and restoration efforts in real time. With the right resources in hand, the scientists who dedicate their careers to understanding and restoring South Florida’s ecology share a hopeful outlook. “Nature and people can absolutely coexist,” said Meenakshi Chabba [The Everglades Foundation—Ecologist and Resilience Scientist]. “But what we need is good science and good management to reach that goal.” The Everglades Foundation provides scientific evaluation and guidance to the elected officials and governmental institutions responsible for the implementation of the Comprehensive Everglades Restoration Plan (CERP), a federal program approved by Congress in 2000 that outlines a 30-year plan to restore Florida’s wetland ecology. The Foundation sees NASA’s BlueFlux campaign as an important accompaniment to that goal. “The [Daily Flux Predictions for South Florida] data product is incredibly valuable, because it provides us with an indicator of the health of the whole system,” said Steve Davis [The Everglades Foundation—Chief Science Officer]. “We know how valuable the wetlands are, but we need this reliable science from NASA and the BlueFlux Campaign to help translate those benefits into something we can use to reach people as well as policymakers.” Researchers hope the product can inform decisions about the management of Florida’s wetlands, the preservation of which is not only a necessity but – to many – a responsibility. “These impacts are of our own doing,” added Chabba. “So, now it’s incumbent upon us to make these changes and correct the mistakes of the past.” Next, the BlueFlux team is shifting their focus to what they call BlueFlux 2. This stage of the project centers around further analysis of the data collected during fieldwork campaigns and outlines the deployment of the beta version of Daily BlueFlux Predictions for South Florida, which will help generate a more accurate evaluation of flux for the many wetland ecosystems that exist beyond Florida’s borders. “We’re trying to contribute to a better understanding of global carbon markets and inspire further and more ambitious investments in these critical stocks of blue carbon,” said Poulter. “First, we want to scale this work to the Caribbean, where we have these great maps of mangrove distribution but limited data on flux.” An additional BlueFlux fieldwork deployment is slated for 2026, with plans to make flux measurements above sites targeted by the state for upcoming restoration initiatives, such as the Everglades Agricultural Area Environmental Protection District. In the Agricultural Area, construction is underway on a series of reservoirs that will store excess water during wet seasons and provide a reserve source of water for wildlife and residents during dry seasons. As the landscape evolves, BlueFlux will help local officials evaluate how Florida’s wetlands are responding to efforts designed to protect the state’s most precious natural resource – and all those who depend on it.

MuSat2 at Vandenberg Air Force Base, prior to launch. MuSat2 leverages a dual-frequency science antenna developed with support from NASA to measure phenomena such as ocean wind speed. Muon Space A science antenna developed with support from NASA’s Earth Science Technology Office (ESTO) is now in low-Earth orbit aboard MuSat2, a commercial remote-sensing satellite flown by the aerospace company Muon Space. The dual-frequency science antenna was originally developed as part of the Next Generation GNSS Bistatic Radar Instrument (NGRx). Aboard MuSat2, it will help measure ocean surface wind speed—an essential data point for scientists trying to forecast how severe a burgeoning hurricane will become. “We’re very interested in adopting this technology and pushing it forward, both from a technology perspective and a product perspective,” said Jonathan Dyer, CEO of Muon. Using this antenna, MuSat2 will gather signals transmitted by navigation satellites as they scatter off Earth’s surface and back into space. By recording how those scattered navigation signals change as they interact with Earth’s surface, MuSat2 will provide meteorologists with data points they can use to study severe weather. “We use the standard GPS signals you know—the navigation signals that work for your car and your cell phone,” explained Chris Ruf, director of the University of Michigan Space Institute and principal investigator for NGRx. Ruf designed the entire NGRx system to be an updated version of the sensors on NASA’s Cyclone Global Navigation Satellite System (CYGNSS), another technology he developed with support from ESTO. Since 2016, data from CYGNSS has been a critical resource for people dedicated to forecasting hurricanes. The science antenna aboard MuSat2 enables two key improvements to the original CYGNSS design. First, the antenna allows MuSat2 to gather measurements from satellites outside the U.S.-based GPS system, such as the European Space Agency’s Galileo satellites. This capability enables MuSat2 to collect more data as it orbits Earth, improving its assessments of conditions on the planet’s surface. Second, whereas CYGNSS only collected cross-polar radar signals, the updated science antenna also collects co-polar radar signals. This additional information could provide improved information about soil moisture, sea ice, and vegetation. “There’s a whole lot of science value in looking at both polarization components scattering from the Earth’s surface. You can separate apart the effects of vegetation from the effects of surface, itself,” explained Ruf. Hurricane Ida, as seen from the International Space Station. NASA-developed technology onboard MuSat2 will help supply the U.S. Air Force with critical data for producing reliable weather forecasts. NASA For Muon Space, this technology infusion has been helpful to the company’s business and science missions. Dallas Masters, Vice President of Muon’s Signals of Opportunity Program, explains that NASA’s investments in NGRx technology made it much easier to produce a viable commercial remote sensing satellite. According to Masters, “NGRx-derived technology allowed us to start planning a flight mission early in our company’s existence, based around a payload we knew had flight heritage.” Dyer agrees. “The fact that ESTO proves out these measurement approaches – the technology and the instrument, the science that you can actually derive, the products from that instrument – is a huge enabler for companies like ours, because we can adopt it knowing that much of the physics risk has been retired,” he said. Ultimately, this advanced antenna technology for measuring ocean surface wind speed will make it easier for researchers to turn raw data into actionable science products and to develop more accurate forecasts. “Information is absolutely precious. When it comes to forecast models and trying to understand what’s about to happen, you have to have as good an idea as you can of what’s already happening in the real world,” said oceanographer Lew Gramer, an Associate Scientist with the Cooperative Institute For Marine And Atmospheric Studies and NOAA’s Hurricane Research Division.

Earth Observer Earth Home Earth Observer Home Editor’s Corner Feature Articles Meeting Summaries News Science in the News Calendars In Memoriam More Archives 22 min read Summary of the Second OMI–TROPOMI Science Team Meeting Introduction The second joint Ozone Monitoring Instrument (OMI)–TROPOspheric Monitoring Instrument (TROPOMI) Science Team (ST) meeting was held June 3–6, 2024. The meeting used a hybrid format, with the in-person meeting hosted at the National Center for Atmospheric Research (NCAR) in Boulder, CO. This was the first OMI meeting to offer virtual participation since the COVID-19 travel restrictions. Combining the onsite and virtual attendees, the meeting drew 125 participants – see Photo. OMI flies on NASA’s Earth Observing System (EOS) Aura platform, launched July 15, 2004. TROPOMI flies on the European Space Agency’s (ESA)–Copernicus Sentinel-5 Precursor platform. OMI has collected nearly 20 years of data and TROPOMI now has amassed 5 years of data. Meeting content was organized around the following four objectives: discussion of the final reprocessing of OMI data (called Collection 4) and of data preservation; discussion of OMI data continuity and enhancements using TROPOMI measurements; development of unique TROPOMI products [e.g., methane (CH4)], applications (e.g., tracking emissions – and using them as indicators of socioeconomic and military activities), and new focus regions (e.g., Africa); and leverage synergies between atmospheric composition (AC) and greenhouse gas (GHG) missions, which form the international constellation of low Earth orbit (LEO) and geostationary orbit (GEO) satellites. The remainder of this article summarizes the highlights from each day of the meeting. Photo. Group photo of the in-person participants at the OMI–TROPOMI Science Team meeting. Photo credit: Shaun Bush/NCAR’s Atmospheric Chemistry Observations & Modeling DAY ONE The topics covered on the first day of the meeting included OMI instrument performance, calibration, final Collection 4 reprocessing, and plans for data preservation. OMI and Data Products Update Pieternel Levelt [Royal Netherlands Meteorological Institute (KNMI)—OMI Principal Investigator (PI) and NCAR’s Atmospheric Chemistry Observations & Modeling (ACOM) Laboratory—Director] began her presentation by dedicating the meeting to the memory of Johan de Vries, whose untimely death came as a shock to the OMI and TROPOMI teams – see In Memoriam: Johan de Vries for a celebration of his accomplishments and contributions to the OMI-TROPOMI team. She then went on to give a status update on OMI, which is one of two currently operating instruments on EOS Aura [the other being the Microwave Limb Sounder (MLS)]. OMI is the longest operating and stable ultraviolet–visible (UV-VIS) spectrometer. It continues to “age gracefully” thanks to its design, contamination control measures undertaken after the launch, and stable optical bench temperature. Lessons learned during integration of OMI on the Aura spacecraft (e.g., provide additional charged couple device shielding) and operations (i.e., monitor partial Earth-view port blockages) guided the development and operations of the follow-on TROPOMI mission. Continued monitoring of OMI performance is crucial for extending science- and trend-quality OMI records to the end of the Aura mission (currently expected in 2026). Antje Ludewig [KNMI] described the new OMI Level-1B (L1B) processor (Collection 4), which is based on TROPOMI data flow and optimized calibrations. The processor has been transferred to the U.S. OMI ST, led by Joanna Joiner [NASA’s Goddard Space Flight Center (GSFC)]. Matthew Bandel [Science Systems and Applications, Inc. (SSAI)] described NASA’s new OMI monitoring tools. Sergey Marchenko [SSAI] discussed OMI daily spectral solar irradiance (SSI) data, which are used for monitoring solar activity and can be compared with the dedicated Total and Spectral Solar Irradiance Sensor (TSIS-1) on the International Space Station. Continuation of OMI measurements will allow comparisons with the upcoming NASA TSIS-2 mission. Antje Inness [European Centre for Medium-range Weather Forecasts (ECMWF)] described operational assimilation of OMI and TROPOMI near-real time data into the European Copernicus Atmosphere Monitoring Service (CAMS) daily analysis/forecast and re-analysis – see Figure 1. In Memoriam: Johan de Vries Johan de Vries June 10, 1956 – May 8, 2024 Johan de Vries [Airbus Netherlands—Senior Specialist Remote Sensing] passed away suddenly on May 8, 2024, after a distinguished career. As a member of the Ozone Monitoring Instrument (OMI)–TROPOspheric Monitoring Instrument (TROPOMI) program, Johan conceptualized the idea of using a two-dimensional (2D) charged couple detector (CCD) for the OMI imaging spectrometer. This “push-broom” design led to high-spatial resolution spectra combined with high-spatial resolution and daily global coverage capability. His pioneering design for OMI has now been repeated on several other U.S. and international atmospheric composition measuring instruments – in both low and geostationary orbits – that are either in orbit or planned for launch soon. This achievement ensures that Johan’s legacy will live on for many years to come as these push-broom Earth observing spectrometers result in unprecedented data for environmental research and applications. The OMI and TROPOMI teams express their deepest condolences to de Vries family and colleagues over this loss. Figure 1.

Updates on OMI and TROPOMI Level-2 Data Products The U.S. and Netherlands OMI STs continue to collaborate closely on reprocessing and improving OMI and TROPOMI L2 science products. During the meeting, one or more presenters reported on each product, which are described in the paragraphs that follow. Serena Di Pede [KNMI] discussed the latest algorithm updates to the Collection 4 OMI Total Column Ozone (O3) product, which is derived using differential absorption spectroscopy (DOAS). She compared results from the new algorithm with the previous Collection 3 and with both the TROPOMI and OMI NASA O3 total column (Collection 3) algorithms. Collection 4 improved on previous versions by reducing the retrieval fit error and the along-track stripes of the product. Juseon “Sunny” Bak and Xiong Liu [both from Smithsonian Astrophysical Observatory (SAO)] gave updates on the status of the Collection 4 O3 profile products. Lok Lamsal [GSFC/University of Maryland, Baltimore County (UMBC)] and Henk Eskes [KNMI] compared Collection 3 and Collection 4 of the nitrogen dioxide (NO2) products. Zolal Ayzpour [SAO] discussed the status of the OMI Collection 4 formaldehyde (HCHO) product. Hyeong-Ahn Kwon [SAO] presented a poster that updated the Glyoxal product. Omar Torres [GSFC] and Changwoo Ahn [GSFC/SSAI] presented regional trend analyses using the re-processed OMI Collection 4 absorbing aerosol product – see Figure 2. Figure 2. Reprocessed OMI records (from Collection 4) of monthly average aerosol optical depth (AOD) at 388 nm derived from the OMI aerosol algorithm (OMAERUV) over Western North America (WNA): 30°N–50°N, 110°W–128°W) [top] and over Eastern China (EC): 25°N–43°N, 112°E–124°E) [bottom]. A repeatable annual cycle over WNA occurred with autumn minimum at around 0.1 and a spring maximum in the vicinity of 0.4 during the 2005–2016 period. After 2017 much larger AOD maxima in the late summer are associated with wildfire smoke occurrence. Over EC (bottom) the 2005–2014 AOD record depicts a large spring maxima (0.7 and larger) due to long-range transport of dust and secondary pollution aerosols followed by late autumn minima (around 0.3). A significant AOD decrease is observed starting in 2015 with reduced minimum and maximum values to about 0.2 and 0.5 respectively. The drastic change in AOD load over this region is associated with pollution control measures enacted over the last decade. Figure credit: Changwoo Ahn/GSFC/SSAI and Omar Torres/GSFC Updates on EOS Synergy Products Several presenters and posters during the meeting gave updates on EOS synergy products, where OMI data are combined with data from another instrument on one of the EOS flagships. These are described below. Brad Fisher [SSAI] presented a poster on the Joint OMI–Moderate Resolution Imaging Spectroradiometer (MODIS) cloud products. Wenhan Qin [GSFC/SSAI] presented a poster on the MODIS–OMI Geometry Dependent Lambertian Equivalent Surface Reflectivity (GLER) product. Jerry Ziemke [GSFC and Morgan State University (MSU)] presented on the OMI–MLS Tropospheric Ozone product that showed post-COVID tropospheric O3 levels measured using this product, which are consistent with similar measurements obtained using other satellite O3 data – see Figure 3. Figure 3. Anomaly maps of merged tropospheric column O3 (TCO) satellite data (Dobson Units) for spring–summer 2020–2023. In this context, an anomaly is defined as deseasonalized O3 data. The anomaly maps are derived by first calculating seasonal climatology maps for 2016–2019 (i.e., pre-COVID pandemic) and then subtracting these climatology maps from the entire data record. Note: The sensors used in this analysis include: the Ozone Mapping and Profiler Suite (OMPS)/ Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2) and Cross-track Infrared Sounder (CrIS) on the Joint Polar Satellite System (JPSS) missions, which currently include the joint NASA–NOAA Suomi National Polar-orbiting Partnership (Suomi NPP), NOAA-20, and NOAA-21; the Earth Polychromatic Imaging Camera (EPIC)/MERRA-2 on the Deep Space Climate Observatory (DSCOVR); the Ozone Monitoring Instrument (OMI) and Microwave Limb Sounder (MLS), both on EOS Aura; the Infrared Atmospheric Sounding Interferometer (IASI)/ Fast Optimal Retrievals on Layers (FORLI), IASI/SOftware for Fast Retrievals of IASI Data (SOFRID), and IASI/Global Ozone Monitoring Experiment–2 (GOME2). IASI flies on the European MetOp-A, -B, and -C missions. The OMPS/MERRA-2 and EPIC/MERRA-2 products subtract coincident MERRA-2 stratospheric column O3 from total O3 to derive tropospheric column O3. Figure credit: Jerry Ziemke/GSFC and Morgan State University (MSU) Updates on Multisatellite Climate Data Records The OMI ST also discussed refining and analyzing multisatellite climate data records (CDRs) that have been processed with consistent algorithms. Several presenters reported on this work, who are mentioned below. Jenny Stavrakou [Koninklijk Belgisch Instituut voor Ruimte-Aeronomie, Royal Belgian Institute for Space Aeronomy (BIRA–IASB)], reported on work focusing on the OMI and TROPOMI HCHO CDR and Huan Yu [BIRA–IASB)] reported harmonized OMI and TROPOMI cloud height datasets based on improved O2-O2 absorption retrieval algorithm. Lok Lamsal [GSFC/UMBC, Goddard Earth Sciences Technology and Research (GESTAR) II], Henk Eskes, and Pepijn Veefkind [KNMI] reported on the OMI and TROPOMI NO2 CDRs – see Figure 4. Si-Wan Kim [Yonsei University, South Korea] reported on OMI and TROPOMI long-term NO2 trends. Figure 4. OMI nitrogen dioxide (NO2) time series bridging the first GOME mission (which flew on the European Remote Sensing Satellite–2 (ERS–2) from 1995–2011 with limited coverage after 2003) and measurements from the two currently operating missions – OMI (2004–present) and TROPOMI (2017–present) – offer consistent climate data records that allow for studying long-term changes. This example shows tropospheric NO2 column time series from three instruments over Phoenix, AZ. The overlap between the OMI and TROPOMI missions allows for intercomparison between the two, which is crucial to avoid continuity-gaps in multi-instrument time series. The ERS-2 (GOME) had a morning equator crossing time (10:30 AM), while Aura (OMI) and Metop (TROPOMI) have afternoon equator crossing times of 1:45 PM and 1:30 PM respectively. Figure credit: Lok Lamsal/GSFC/University of Maryland, Baltimore County (UMBC) Update on Aura’s Drifting Orbit Bryan Duncan [GSFC—Aura Project Scientist] closed out the first day with a presentation summarizing predictions of Aura’s drifting orbit. Overall, the impact of Aura’s drift is expected to be minor, and the OMI and MLS teams will be able to maintain science quality data for most data products. He thanked the OMI/TROPOMI ST and user community for expressing their strong support for continuing Aura observations until the end of the Aura mission in mid–2026. DAY TWO The second day of the meeting focused on current and upcoming LEO and GEO Atmospheric Composition (AC) missions. TROPOMI Mission and Data Product Updates Veefkind presented an update on the TROPOMI mission, which provides continuation and enhancements for all OMI products. Tobias Borssdorf [Stichting Ruimte Onderzoek Nederland (SRON), or Netherlands Institute for Space Research] explained how TROPOMI, with its innovative shortwave infrared (SWIR) spectrometer, measures CH4 and carbon monoxide (CO). This approach continues measurements that began by the Measurements of Pollution in the Troposphere (MOPITT) instrument on Terra. Hiren Jethva [NASA Airborne Science Program] and Torres presented new TROPOMI near-UV aerosol products, including a new aerosol layer optical centroid height product, which takes advantage of the TROPOMI extended spectral range – see Figure 5. Figure 5. Global gridded (0.10° x 0.10°) composite map of aerosol layer optical centroid height (AH) retrieved from TROPOMI O2-B band observations from May–September 2023. Figure credit: Hiren Jethva/NASA Airborne Science Program GEMS–TEMPO–Sentinel-4 (UVN): A Geostationary Air Quality Constellation TROPOMI global observations serve as a de facto calibration standard used to homogenize a new constellation of three missions that will provide AC observations for most of the Northern Hemisphere from GEO. Two of the three constellation members are already in orbit. Jhoon Kim [Yonsei University—PI] discussed the Geostationary Environmental Monitoring Spectrometer (GEMS), launched on February 19, 2020 aboard the Republic of Korea’s GEO-KOMPSAT-2B satellite. It is making GEO AC measurements over Asia. The GEMS team is working on validating measurements of NO2 diurnal variations using ground-based measurements from the PANDORA Global Network over Asia and aircraft measurements from the ASIA–AQ field campaign. Liu discussed NASA’s Tropospheric Emission Monitoring of Pollution (TEMPO) spectrometer, launched on April 7, 2023, aboard a commercial INTELSAT 40E satellite. From its GEO vantage point, TEMPO can observe the Continental U.S., Southern Canada, Mexico, and the coastal waters of the Northwestern Atlantic and Northeastern Pacific oceans. Gonzales Abad [SAO] presented the first measurements from TEMPO. He explained that TEMPO’s design is similar to GEMS, but GEMS includes an additional visible and near infrared (VNIR) spectral channel (540–740 nm) to measure tropospheric O3, O2, and water vapor (H2Ov). TEMPO can perform optimized morning scans, twilight scans, and scans with high temporal resolution (5–10 minutes) over selected regions. Abad reported that the TEMPO team released L1B spectra and the first provisional public L2 products (Version 3), including NO2, HCHO, and total column O3. Andrew Rollins [National Oceanic and Atmospheric Administration’s (NOAA) Chemical Sciences Laboratory (CSL)] reported that the TEMPO team is working on validation of provisional data using both ground-based data from PANDORA spectrometers and data collected during several different airborne campaigns completed during the summer of 2023 and compiled on the AGES+ website. Ben Veihelmann [ESA’s European Space Research and Technology Center—PI] explained that ESA’s Copernicus Sentinel-4 mission will be the final member of the GEO AC constellation. Veefkind summarized the Sentinel-4 mission, which is expected to launch on the Meteosat Third Generation (MTG)-Sounder 1 (MTG-S1) platform in 2025. The mission is dedicated to measuring air quality and O3 over Europe and parts of the Atlantic and North Africa. Sentinel-4 will deploy the first operational UV-Vis-NIR (UVN) imaging spectrometer on a geostationary satellite. (Airbus will build UVN, with ESA providing guidance.) Sentinel-4 includes two instruments launched in sequence on MTG-S1 and MTG-S2 platforms designed to have a combined lifetime of 15 years. The mission by the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) will operate Sentinel-4, and the Deutsches Zentrum für Luft- und Raumfahrt (DLR) or German Aerospace Center will be responsible for operational L2 processing. These three GEO AC missions, along with the upcoming ESA/EUMETSAT/Copernicus LEO (morning orbit, 9:30 a.m.) Sentinel-5 (S5) mission, will complete a LEO–GEO satellite constellation that will enable monitoring of the most industrialized and polluted regions in the Northern Hemisphere into the 2030s. Sentinel-5 will not continue the OMI–TROPOMI data record in the early afternoon; however, it will be placed in the morning orbit and follow ESA’s Global Ozone Monitoring Experiment (GOME) and EUMETSAT GOME-2 missions. By contrast, GEO AC observations over the Southern Hemisphere are currently not available. Several presenters described ongoing projects for capacity building for LEO satellite air quality data uptake and emission monitoring in Africa and advocated for the new geostationary measurements. Synergy with Other Current or Upcoming Missions Attendees discussed the synergy between upcoming AC, GHG, and ocean color missions. Current trends in satellite AC measurements are toward increased spatial resolution and combined observations of short-lived reactive trace gases – which are important for air quality (AQ) monitoring – and long-lived GHG – which are important for climate monitoring and carbon cycle assessments. Some trace gases (e.g., O3 and CH4) are both polluters and GHG agents. Others [e.g., NO2 and sulfur dioxide (SO2 )] are aerosol [particulate matter (PM)] and O3 precursors and are used as proxies and spatial indicators for anthropogenic CO2 and CH4 emissions. Yasjka Meijer [ESA—Copernicus Anthropogenic Carbon Dioxide Monitoring (CO2M) Mission Scientist]) reviewed the plans for CO2M, which includes high-resolution measurements [~4 km2 (~1.5 mi2)] of CO2 , CH4 , and NO2. Jochen Landgraf [SRON] described ESA’s new Twin Anthropogenic Greenhouse Gas Observers (TANGO) mission, which has the objective to measure CO2 , CH4 , and NO2 at even higher spatial resolution [~300 m (~984 ft)] using two small CubeSat spectrometers flying in formation. Hiroshi Tanimoto [National Institute for Environmental Studies, Japan] described the Japan Aerospace Exploration Agency’s (JAXA) Global Observing SATellite for greenhouse gases and water cycle (GOSAT-GW) mission, which includes the Total Anthropogenic and Natural Emission mapping SpectrOmeter (TANSO-3) spectrometer to simultaneously measure CO2 , CH4, and NO2 with ~1–3 km (~0.6–1.8 mi) spatial resolution in focus mode. GOSAT-GW will also fly the Advanced Microwave Scanning Radiometer 3 (AMSR3). Joanna Joiner [GSFC—Geostationary Extended Operations (GeoXO) Project Scientist and ACX Instrument Scientist] described the plans for the next-generation U.S. geosynchronous satellite constellation, which will consist of three satellites covering the full Earth disk: GEO-East, GEO-West, and GEO-Central. (By contrast, the current Geostationary Operational Environmental Satellite (GOES) series has two satellites: GOES–East and GOES–West.) GEO-Central will carry an advanced infrared sounder (GXS) for measuring vertical profiles of many trace gases, temperature and humidity, and a new UV-VIS spectrometer (ACX), which is a follow-on to TEMPO for AQ applications. Both GXS and ACX instruments will be built by BAE Systems, which acquired Ball Aerospace and Technology, and will also build the GeoXO ocean color spectrometer (OCX). Andrew Sayer [UMBC] described NASA’s Plankton, Aerosols, Clouds, and ocean Ecosystem (PACE), which launched on February 8, 2024. The PACE payload includes a high-spatial resolution [~1 km (~0.6 mi) at nadir] Ocean Color Instrument (OCI), which is a UV-Vis-NIR spectrometer with discrete SWIR bands presenting additional opportunities for synergistic observations with the AC constellation. Sayer presented OCI “first light” aerosol data processed using the unified retrieval algorithm developed by Lorraine Remer [UMBC]. The second day concluded with a joint crossover session with NASA’s Health and Air Quality Applied Sciences Team (HAQAST) followed by a poster session. Several OMI–TROPOMI STM participants presented on a variety of topics that illustrate how OMI and TROPOMI data are being used to support numerous health and AQ applications. Duncan, who is also a member of HAQAST team, presented “20 years of health and air quality applications enabled by OMI data.” He highlighted OMI contributions to AQ and health applications, including NO2 trend monitoring, inferring trends of co-emitted species [e.g., CO2, CO, some Volatile Organic Compounds (VOCs)], validation of new satellite missions (e.g., TEMPO, PACE), and burden of disease studies. DAY THREE Discussions on the third day focused on advanced retrieval algorithms, leading to new products and new applications for OMI and TROPOMI data. Several presentations described applications of TROPOMI CH4 data and synergy with small satellites. Advanced Retrieval Algorithms and New Data Products Ilse Aben [SRON] described TROPOMI global detection of CH4 super-emitters using an automated system based on Machine Learning (ML) techniques – see Figure 6. Berend Schuit [SRON] provided additional detail on these methods. He introduced the TROPOMI CH4 web site to the meeting participants. He explained how TROPOMI global CH4 measurements use “tip-and-cue” dedicated satellites with much higher spatial resolution instruments [e.g., GHGSat with ~25-m (~82-ft) resolution] to scan for individual sources and estimate emission rates. Most CH4 super-emitters are related to urban areas and/or landfills, followed by plumes from gas and oil industries and coal mines. Figure 6. Methane plume map produced by SRON shows TROPOMI large CH4 emission plumes for the week of the OMI–TROPOMI meeting (June 3–6, 2024). Figure credit: Itse Aben/Stichting Ruimte Onderzoek Nederland (SRON) Alba Lorente [Environmental Defense Fund—Methane Scientist] introduced a new MethaneSAT satellite launched in March 2024, which aims to fill the gap in understanding CH4 emissions on a regional scale [200 x 200 km2 (~77 x 77 mi2)] from at least 80% of global oil and gas production, agriculture, and urban regions. Alex Bradley [University of Colorado, Boulder] described improvements to TROPOMI CH4 retrievals that were achieved by correcting seasonal effects of changing surface albedo. Daniel Jacob [Harvard University] presented several topics, including the highest resolution [~30 m (~98 ft)] NO2 plume retrievals from Landsat-8 – see Figure 7 – and Sentinel-2 imagers. He also discussed using a ML technique trained with TROPOMI data to improve NO2 retrievals from GEMS and modeling NO2 diurnal cycle and emission estimates. He introduced the ratio of ammonia (NH3) to NO2 (NH3/NO2) as an indicator of particulate matter with diameters less than 2.5 µm (PM2.5) nitrate sensitivity regime. Jacob emphasized the challenges related to satellite NO2 retrievals (e.g., accounting for a free-tropospheric NO2 background and aerosols). Figure 7. Landsat Optical Land Imager (OLI) image, obtained on October 17, 2021 over Saudi Arabia, shows power plant exhaust, which contains nitrogen dioxide (NO2) drifting downwind from the sources (the two green circles are the stacks). The ultra-blue channel (430–450 nm) on OLI enables quantitative detection of NO2 in plumes from large point sources at 30-m (~98-ft) resolution. This provides a unique ability for monitoring point-source emissions of oxides of nitrogen (NOx). The two stacks in the image are separated by 2 km (~1.2 mi). Figure credit: Daniel Jacob – repurposed from a 2024 publication in Proceedings of the National Academies of Sciences (PNAS) Steffen Beirle [Max Planck Institute for Chemistry, Germany] explained his work to fit TROPOMI NO2 column measurements to investigate nitric oxide (NO) to NO2 processing in power plant plumes. Debra Griffin [Environment and Climate Change Canada (ECCC)] used TROPOMI NO2 observations and ML random forest technique to estimate NO2 surface concentrations. Sara Martinez-Alonso [NCAR] investigated geographical and seasonal variations in NO2 diurnal cycle using GEMS and TEMPO data. Ziemkecombined satellite O3 data to confirm a persistent low anomaly (~5–15%) in tropospheric O3 after 2020. Jethva presented advanced OMI and TROPOMI absorbing aerosol products. Yu described improved OMI and TROPOMI cloud datasets using the O2-O2 absorption band at 477 nm. Nicholas Parazoo [Jet Propulsion Laboratory (JPL)] described TROPOMI Fraunhofer line retrievals of red solar-induced chlorophyll fluorescence (SIF) near O2-B band (663–685 nm) to improve mapping of ocean primary productivity. Liyin He [Duke University] described using satellite terrestrial SIF data to study the effect of particulate pollution on ecosystem productivity. New Applications Zachary Fasnacht [SSAI] used OMI and TROPOMI spectra to train a neural network to gap-fill MODIS and Visible Infrared Imaging Radiometer Suite (VIIRS) ocean color data under aerosol, sun glint, and partly cloudy conditions. This ML method can also be applied to PACE OCI spectra. Anu-Maija Sundström [Finnish Meteorological Institute (FMI)] used OMI and TROPOMI SO2 and O3 data as proxies to study new particle formation events. Lindsey Anderson [University of Colorado, Boulder] described how she used TROPOMI NO2 and CO measurements to estimate the composition of wildfire emissions and their effect on forecasted air quality. Heesung Chong [SAO] applied OMI bromine oxide (BrO) retrievals to the NOAA operational Ozone Mapping and Profiling Suite Nadir Mapper (OMPS-NM) on joint NOAA–NASA Suomi-National Polar-orbiting Partnership (Suomi NPP) satellite with the possibility to continue afternoon measurements using similar OMPS-NM instruments on the four Joint Polar Satellite System missions (JPSS-1,-2,-3,-4) into the 2030s. (JPSS-1 and -2 are now in orbit and known as NOAA-20 and -21 respectively; JPSS-4 is planned for launch in 2027, with JPSS-3 currently targeted for 2032.) Kim demonstrated the potential for using satellite NO2 and SO2 emissions as a window into socioeconomic issues that are not apparent by other methods. For example, she showed how OMI and TROPOMI data were widely used to monitor air quality improvements in the aftermath of COVID-19 lockdowns. (Brad Fisher [SSAI] presented a poster on a similar topic.) Cathy Clerbaux [Center National d’Études Spatiale (CNES), or French Space Agency] showed how her team used TROPOMI NO2 data to trace the signal emitted by ships and used this information to determine how the shipping lanes through the Suez Canal changed in response to unrest in the Middle East. Iolanda Ialongo [FMI] showed a similar drop of NO2 emissions over Donetsk region due to the war in Ukraine. Levelt showed how OMI and TROPOMI NO2 data are used for capacity-building projects and for air quality reporting in Africa. She also advocated for additional geostationary AQ measurements over Africa. DAY FOUR Discussions on the final day focused on various methods of assimilating satellite data into air quality models for emission inversions and aircraft TEMPO validation campaigns. The meeting ended with Levelt giving her unique perspective on the OMI mission, as she reflected on more than two decades being involved with the development, launch, operation, and maintenance of OMI. Assimilating Satellite Data into Models for Emissions Brian McDonald [CSL] described advance chemical data assimilation of satellite data for emission inversions and the GReenhouse gas And Air Pollutants Emissions System (GRA2PES). He showed examples of assimilations using TROPOMI and TEMPO NO2 observations to adjust a priori emissions. He also showed that when TEMPO data are assimilated, NOx emissions adjust faster and tend to perform better at the urban scale. Adrian Jost [Max Planck Institute for Chemistry] described the ESA-funded World Emission project to improve pollutant and GHG emission inventories using satellite data. He showed examples of TROPOMI SO2 emissions from large-point sources and compared the data with bottom-up and NASA SO2 emissions catalogue. Ivar van der Velde [SRON] presented a method to evaluate fire emissions using new satellite imagery of burned area and TROPOMI CO. Helene Peiro [SRON] described her work to combine TROPOMI CO and burned area information to compare the impact of prescribed fires versus wildfires on air quality in the U.S. She concluded that prescribed burning reduces CO pollution. Barbara Dix [University of Colorado, Boulder, Cooperative Institute for Research in Environmental Sciences] derived NOx emissions from U.S. oil and natural gas production using TROPOMI NO2 data and flux divergence method. She estimated TROPOMI CH4 emissions from Denver–Julesburg oil and natural gas production. Dix explained that the remaining challenge is to separate oil and gas emissions from other co-located CH4 sources. Ben Gaubert [NCAR, Atmospheric Chemistry Observations and Modeling] described nonlinear and non-Gaussian ensemble assimilation of MOPITT CO using the data assimilation research testbed (DART). Andrew (Drew) Rollings [CSL] presented first TEMPO validation results from airborne field campaigns in 2023 (AGES+ ), including NOAA CSL Atmospheric Emissions and Reactions observed from Megacities to Marine Aeras (AEROMMA) and NASA’s Synergistic TEMPO Air Quality Science (STAQS) campaigns. A Reflection on Twenty Years of OMI Observations Levelt gave a closing presentation in which she reflected on her first involvement with the OMI mission as a young scientist back in 1998. This led to a collaboration with the international ST to develop the instrument, which was included as part of Aura’s payload when it launched in July 2004. She reminisced about important highlights from 2 decades of OMI, e.g., the 10-year anniversary STM at KNMI in 2014 (see “Celebrating Ten Years of OMI Observations,” The Earth Observer, May–Jun 2014, 26:3, 23–30), and the OMI ST receiving the NASA/U.S. Geological Survey Pecora award in 2018 and the American Meteorological Society’s Special award in 2021. Levelt pointed out that in this combined OMI–TROPOMI meeting the movement towards using air pollution and GHG data together became apparent. She ended by saying that the OMI instrument continues to “age gracefully” and its legacy continues with the TROPOMI and LEO–GEO atmospheric composition constellation of satellites that were discussed during the meeting. Conclusion Overall, the second OMI–TROPOMI STM acknowledged OMI’s pioneering role and TROPOMI’s unique enhancements in measurements of atmospheric composition: Ozone Layer Monitoring: Over the past two decades, OMI has provided invaluable data on the concentration and distribution of O3 in the Earth’s stratosphere. This data has been crucial for understanding and monitoring the recovery of the O3 layer following international agreements, such as the Montreal Protocol. Air Quality Assessment: OMI’s high-resolution measurements of air pollutants, such as NO2, SO2, and HCHO, have significantly advanced our understanding of air quality. This information has been vital for tracking pollution sources, studying their transport and transformation, and assessing their impact on human health and the environment. Climate Research: The data collected by OMI has enhanced our knowledge of the interactions between atmospheric chemistry and climate change. These insights have been instrumental in refining climate models and improving our predictions of future climate scenarios. Global Impact: The OMI instrument has provided near-daily global coverage of atmospheric data, which has been essential for scientists and policymakers worldwide. The comprehensive and reliable data from OMI has supported countless research projects and informed decisions aimed at protecting and improving our environment. OMI remains one of the most stable UV/Vis instruments over its two decades of science and trend quality data collection. The success of the OMI and TROPOMI instruments is a testament to the collaboration, expertise, and dedication of both teams.

Teams with NASA and Lockheed Martin prepare to conduct testing on NASA’s Orion spacecraft on Thursday, Nov. 7, 2024, in the altitude chamber inside the Neil A. Armstrong Operations and Checkout building at NASA’s Kennedy Space Center in Florida. Lockheed Martin/David Wellendorf Teams lifted NASA’s Orion spacecraft for the Artemis II test flight out of the Final Assembly and System Testing cell and moved it to the altitude chamber to complete further testing on Nov. 6 inside the Neil A. Armstrong Operations and Checkout building at NASA’s Kennedy Space Center in Florida. Engineers returned the spacecraft to the altitude chamber, which simulates deep space vacuum conditions, to complete the remaining test requirements and provide additional data to augment data gained during testing earlier this summer. The Artemis II test flight will be NASA’s first mission with crew under the Artemis campaign, sending NASA astronauts Victor Glover, Christina Koch, and Reid Wiseman, as well as CSA (Canadian Space Agency) astronaut Jeremy Hansen, on a 10-day journey around the Moon and back.

Researchers demonstrated the feasibility of 3D bioprinting a meniscus or knee cartilage tissue in microgravity. This successful result advances technology for bioprinting tissue to treat musculoskeletal injuries on long-term spaceflight or in extraterrestrial settings where resources and supply capacities are limited. BFF Meniscus-2 evaluated using the BioFabrication Facility to 3D print knee cartilage tissue using bioinks and cells. The meniscus is the first engineered tissue of an anatomically relevant shape printed on the station. Manufactured human tissues have potential as alternatives to donor organs, which are in short supply. Bioprinting in microgravity overcomes some of the challenges present in Earth’s gravity, such as deformation or collapse of tissue structures. A human knee meniscus 3D bioprinted in space using the International Space Station’s BioFabrication Facility.Redwire Complex cultures of central nervous system cells known as brain organoids can be maintained in microgravity for long periods of time and show faster development of neurons than cultures on Earth. These findings could help researchers develop treatments for neurodegenerative diseases on Earth and address potential adverse neurological effects of spaceflight. Cosmic Brain Organoids examined growth and gene expression in 3D organoids created with neural stem cells from individuals with primary progressive multiple sclerosis and Parkinson’s disease. Results could improve understanding of these neurological diseases and support development of new treatments. Researchers plan additional studies on the underlying causes of the accelerated neuron maturation. Neural growth in brain organoids that spent more than a month in space. Jeanne Frances Loring, National Stem Cell Foundation Researchers demonstrated that induced pluripotent stem cells (iPSCs) can be processed in microgravity using off the-shelf cell culture materials. Using standard laboratory equipment and protocols could reduce costs and make space-based biomedical research accessible to a broader range of scientists and institutions. Stellar Stem Cells Ax-2 evaluated how microgravity affects methods used to generate and grow stem cells into a variety of tissue types on the ground. iPSCs can give rise to any type of cell or tissue in the human body, and insight into processing in space could support their use in regenerative medicine and future large-scale biomanufacturing of cellular therapeutics in space.

NASA and the military have shared strong connections since the agency’s early days. From the nation’s earliest aeronautic research and the recruitment of test pilot astronauts to modern-day technology development, satellite management, and planetary defense, NASA has built a longstanding partnership with the military. This legacy of collaboration has created natural opportunities for former service members to join NASA’s ranks at the conclusion of their military careers. Lewis Swain is one of the many veterans working at Johnson Space Center in Houston today. Swain was recruited by NASA contractor McDonnell Douglas after leaving the military in 1980. He commissioned as a second lieutenant and served in the Air Force for 12 years, flying nearly 200 combat missions during two tours in Vietnam. “The shuttle program was starting, and they needed ex-military pilots to serve as simulation instructors,” he said. Swain specialized in control and propulsion systems instruction for several years before becoming the training team lead for shuttle missions. Following the Challenger accident in 1986, Swain transitioned to supporting the International Space Station Program and Return to Flight evaluations. He has been a civil servant since 1989 and a training facility manager since 2006. L. Jerry Swain during his Air Force career (left) and as a facility manager at Johnson Space Center in Houston (right).Images courtesy of L. Jerry Swain NASA’s Pathways Internship Program has also provided a point of entry for former service members. John Smith was studying mechanical engineering at the University of Texas at El Paso when he made an impactful Johnson connection. “I met with a former flight director, Ms. Ginger Kerrick, at a career fair hosted by my university,” he said. “Pathways happened to be accepting applications at the time and she enthusiastically encouraged me to apply. I never expected to get a response, much less an offer. I couldn’t say yes fast enough when it came!” For others, the NASA SkillBridge Program has been instrumental in transitioning from the military to civilian careers. The program connects individuals in their final months of military service with a NASA office or organization. SkillBridge fellows work anywhere from 90 to 180 days, contributing their unique skillsets to the agency while building their network and knowledge. Since fellows’ pay and benefits are provided by their military branch, their support comes at no additional cost to NASA. Johnson hosted the agency’s first-ever SkillBridge fellow in spring 2019, paving the way for many others to follow. Albert Meza, an Air Force space professional, was among this first wave of service members at NASA. Approaching retirement from the Air Force in November 2019, Meza planned to move his family back to Houston that summer, then join them in the fall once his military service ended. A colleague encouraged him to apply for SkillBridge because it would let Meza move with his family. Meza was skeptical, noting the military is not typically flexible on moves or timelines, but after a quick meeting with his commanding officer and finding a Johnson team to work with, he was on his way to Houston. “It was unbelievable,” he said. “It kind of fell into my lap.” Albert Meza visits Johnson Space Center’s Space Vehicle Mockup Facility while serving in the Air Force (left) and receives an award from NASA astronaut Rex J. Walheim during his retirement ceremony at Space Center Houston (right). Images courtesy of Albert Meza Today Meza is a payload integration manager for NASA’s CLPS (Commercial Lunar Payload Services) program, working within the Exploration Architecture, Integration, and Science Directorate at Johnson. In this role, he acts as a liaison between payload teams and the vendor developing a lander to help ensure flight requirements are understood and met. Meza is also one of SkillBridge’s on-site coordinators. He said that when he first arrived at Johnson, he realized the program was relatively unknown. “I thought, I need to take the responsibility for waving the flag for SkillBridge at NASA.” Meza works tirelessly to educate service members, military leaders, and NASA supervisors about the program’s benefits. He also emphasizes how easy it is for NASA supervisors to host a fellow. “You get someone for six months who is already disciplined, loyal, and has all of these highly trained credentials,” he said. “Any civil servant supervisor can host a SkillBridge fellow. The only real requirement is that the supervisor can provide IT assets and a work location.” Johnson has hosted more than 25 SkillBridge fellows since the program’s inception. Many fellows have since accepted full-time positions with NASA, including Patricia “Trish” Elliston.

NASA’s Mars rover Curiosity acquired this image of its workspace, which includes several targets for investigation — “Buttress Tree,” “Forester Pass,” “Crater Mountain,” “Mahogany Creek,” and “Filly Lake.” Curiosity used its Left Navigation Camera on Nov. 8, 2024 — sol 4357, or Martian day 4.357, of the Mars Science Laboratory mission — at 00:06:17 UTC. NASA/JPL-Caltech Earth planning date: Friday, Nov. 8, 2024 After the excitement of Wednesday’s plan, it was a relief to come in today to hear that the drive toward our exit from Gediz Vallis completed successfully and that we weren’t perched on any rocks or in any other precarious position. This made for a very smooth planning morning, which is always nice on a Friday after a long week. But that isn’t to say that Curiosity will be taking it easy for the weekend. Smooth planning means we have lots of time to pack in as much science as we can fit. Today, this meant that the geology group (GEO) got to name eight new targets, and the environmental group (ENV) got to spend some extra time contemplating the atmosphere. Reading through the list of target names from GEO felt a bit like reading a travel guide — top rocks to visit when you’re exiting Gediz Vallis! If you look to the front of your rover, what we refer to as the “workspace” (and which you can see part of in the image above), you’ll see an array of rocks. Take in the polygonal fractures of “Colosseum Mountain” and be amazed by the structures of “Tyndall Creek” and “Cascade Valley.” Get up close and personal with our contact science targets, “Mahogany Creek,” “Forester Pass,” and “Buttress Tree.” Our workspace has something for everyone, including the laser spectrometers in the family, who will find plenty to explore with “Filly Lake” and “Crater Mountain.” We have old favorites too, like the upper Gediz Vallis Ridge and the Texoli outcrop. After a busy day sightseeing, why not kick back with ENV and take a deep breath? APXS and ChemCam have you covered, watching the changing atmospheric composition. Look up with Navcam and you may see clouds drifting by, or spend some time looking for dust devils in the distance. Want to check the weather before planning your road trip? Our weather station REMS works around the clock, and Mastcam and Navcam are both keeping an eye on how dusty the crater is. All good vacations must come to an end, but know that when it’s time to drive away there will be many more thrilling sights to come!

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s Voyager 2 captured this image of Uranus while flying by the ice giant in 1986. New research using data from the mission shows a solar wind event took place during the flyby, leading to a mystery about the planet’s magnetosphere that now may be solved.NASA/JPL-Caltech NASA’s Voyager 2 flyby of Uranus decades ago shaped scientists’ understanding of the planet but also introduced unexplained oddities. A recent data dive has offered answers. When NASA’s Voyager 2 spacecraft flew by Uranus in 1986, it provided scientists’ first — and, so far, only — close glimpse of this strange, sideways-rotating outer planet. Alongside the discovery of new moons and rings, baffling new mysteries confronted scientists. The energized particles around the planet defied their understanding of how magnetic fields work to trap particle radiation, and Uranus earned a reputation as an outlier in our solar system. Now, new research analyzing the data collected during that flyby 38 years ago has found that the source of that particular mystery is a cosmic coincidence: It turns out that in the days just before Voyager 2’s flyby, the planet had been affected by an unusual kind of space weather that squashed the planet’s magnetic field, dramatically compressing Uranus’ magnetosphere. “If Voyager 2 had arrived just a few days earlier, it would have observed a completely different magnetosphere at Uranus,” said Jamie Jasinski of NASA’s Jet Propulsion Laboratory in Southern California and lead author of the new work published in Nature Astronomy. “The spacecraft saw Uranus in conditions that only occur about 4% of the time.” The first panel of this artist’s concept depicts how Uranus’s magnetosphere — its protective bubble — was behaving before the flyby of NASA’s Voyager 2. The second panel shows an unusual kind of solar weather was happening during the 1986 flyby, giving scientists a skewed view of the magnetosphere.NASA/JPL-Caltech Magnetospheres serve as protective bubbles around planets (including Earth) with magnetic cores and magnetic fields, shielding them from jets of ionized gas — or plasma — that stream out from the Sun in the solar wind. Learning more about how magnetospheres work is important for understanding our own planet, as well as those in seldom-visited corners of our solar system and beyond. That’s why scientists were eager to study Uranus’ magnetosphere, and what they saw in the Voyager 2 data in 1986 flummoxed them. Inside the planet’s magnetosphere were electron radiation belts with an intensity second only to Jupiter’s notoriously brutal radiation belts. But there was apparently no source of energized particles to feed those active belts; in fact, the rest of Uranus’ magnetosphere was almost devoid of plasma. The missing plasma also puzzled scientists because they knew that the five major Uranian moons in the magnetic bubble should have produced water ions, as icy moons around other outer planets do. They concluded that the moons must be inert with no ongoing activity. Solving the Mystery So why was no plasma observed, and what was happening to beef up the radiation belts? The new data analysis points to the solar wind. When plasma from the Sun pounded and compressed the magnetosphere, it likely drove plasma out of the system. The solar wind event also would have briefly intensified the dynamics of the magnetosphere, which would have fed the belts by injecting electrons into them. The findings could be good news for those five major moons of Uranus: Some of them might be geologically active after all. With an explanation for the temporarily missing plasma, researchers say it’s plausible that the moons actually may have been spewing ions into the surrounding bubble all along. Planetary scientists are focusing on bolstering their knowledge about the mysterious Uranus system, which the National Academies’ 2023 Planetary Science and Astrobiology Decadal Survey prioritized as a target for a future NASA mission. JPL’s Linda Spilker was among the Voyager 2 mission scientists glued to the images and other data that flowed in during the Uranus flyby in 1986. She remembers the anticipation and excitement of the event, which changed how scientists thought about the Uranian system. “The flyby was packed with surprises, and we were searching for an explanation of its unusual behavior. The magnetosphere Voyager 2 measured was only a snapshot in time,” said Spilker, who has returned to the iconic mission to lead its science team as project scientist. “This new work explains some of the apparent contradictions, and it will change our view of Uranus once again.” Voyager 2, now in interstellar space, is almost 13 billion miles (21 billion kilometers) from Earth.

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) María Fernanda Barbarena-Arias (left), an associate professor of biology and instructor for the OCEANOS internship, stands on the sand of Playa Melones, Culebra Island, during the field work section of the internship.NASA ARC/Milan Loiacono What is your name and your role with OCEANOS? My name is María Fernanda Barbarena-Arias. I am an associate professor of biology at the American University of Puerto Rico, Metropolitan Campus. I am also a co-PI in the OCEANOS project, and an instructor and mentor for the students during the internship. What is the importance of a program like OCEANOS, especially in Puerto Rico? I think it makes a difference for the students because it gives them the opportunity to learn and to become familiar with ocean science, and with coastal and marine natural resources. In particular with OCEANOS one of the great [elements] is that usually marine science is offered in the upper system, which is the public university in Puerto Rico, and OCEANOS is engaging a private university where usually students who cannot enter the public system can begin studying. They have those kind of opportunities, because of OCEANOS. What are some ways you’ve seen the students grow over the course of the internship? The growth and changes that I’ve seen in students is mostly gaining confidence in the water. I think it’s great! Their first time they are apprehensive, and then as time passes and they engage more into their projects they seem much more familiar with swimming. The students also become more familiar and more confident on their projects. The first time they try to collect data they ask a lot of questions, and then by the third day they already know what to do. They are really empowered and I love that. What is something you hope the students take with them after this program? I hope that the students learn and become voices to help spread the word about natural sciences: we can study it and work in marine science. Usually in Puerto Rico, natural sciences are seen like a first step when you’re going to be focused in medical science or human health-related disciplines, and so that’s in some ways the tradition; it’s what the public knows. I hope this experience helped the students to spread the word that other kinds of careers are an alternative. I also hope it made them aware that we live in a vulnerable island and that we need to take action to become conscious, and to take action to be ready and to protect our natural resources. How did you become involved in marine science, and eventually OCEANOS? I actually come from Colombia. I did a bachelors degree in biology there and a minor in entomology, because at that point in my life I wanted to work in agriculture and to do pest control. But then I took a class on insect ecology, and I had to do a project and that’s when I discovered that my passion is ecology. So I applied to the University of Puerto Rico and I came here and did my master’s and my bachelor’s in tropical biology, but actually related to forests. But in the meantime I got married to a Puerto Rican guy, so I decided to stay here. Three years later I was able to land a permanent position as a faculty in a private university, and I realized that I didn’t like the way we usually teach science in the classroom. So I began taking trainings and looking for opportunities to mentor students and to teach students in non-traditional settings. I got involved in many projects and I have a strong collaboration with University of Maryland, and we have had these kinds of projects/training/research opportunities for students outside the classroom for many years. And that I why I think one PI called me and invited me to OCEANOS, and here I am.

Suleiman is also the Executive Director of Sociedad Ambiente Marino: a Puerto Rican NGO that works in conservation and coral reef restoration.NASA ARC/Milan Loiacono What is your name and your role with OCEANOS? My name is Samuel Suleiman and I am the Executive Director of Sociedad Ambiente Marino: an NGO in Puerto Rico that has been working for the last 25 years to conserve our coastline and our reefs. During the OCEANOS internship, I am one of the Co-PIs (a co-instructor) for the project, and I’m in charge of the marine ecosystem in Culebra Island. What is the importance of a program like OCEANOS, especially in Puerto Rico? The OCEANOS internship is pretty important for those students that don’t have the opportunity to go directly to our natural resources. Puerto Rico is an archipiélago – an island surrounded with other small islands – and most of the population that we have on the island doesn’t appreciate or understand or protect our resources, because they haven’t had the opportunity to learn about it. OCEANOS provide this experience for these kids and also allows them to grow in different areas; not just in the in the lectures and the information and the marine science data, but also about working together as collaborators. What are some ways you’ve seen the students grow over the course of the internship? They have become more confident in the water compared to where we started, and they have start collaborating amongst themselves in their different research groups. They have also been changing their minds and attitudes, [which is] what we need for a better Puerto Rico and a better world. How did you get into science? I started in science because I wanted to be a pediatrician when I was a kid. I started in the Natural Science College at the University of Puerto Rico, then I changed to education in science. And I try to mix together my experience from the past: I almost drowned when I was five years old. Instead of paralyzing myself with fear of the water, I tried to explore, and I have been exploring since then; since I was five years old. Every time that I have the opportunity, I learn something new from the ocean. What is something that has been rewarding about working with these students? I think that we have to create a new kind of people that protect our resources. People that are willing to take what is needed to make a better world, and a better Puerto Rico. What is something you hope the students take with them after this program? I hope they feel a sense of belonging with the ocean, our coastline, our beaches, our resources, our reefs, our marine ecosystems. And I hope they can be ambassadors of these places.

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Roy Armstrong, an instructor for the OCEANOS internship and marine sciences professor, pilots a small boat around the cays off the coast of La Parguera, Puerto Rico. NASA ARC/Milan Loiacono What is your name and your role with OCEANOS? My name is Ray Armstrong and I am a professor in the Department of Marine Sciences of the University of Puerto Rico. I came to be involved in OCEANOS because my ex-student and good friend Juan Torres-Perez, who works at NASA Ames Research Center, came up with this idea of having an internship for Hispanic students in Puerto Rico in the areas of remote sensing and oceanography, as a way of motivating Hispanic students to pursue careers in technology and oceanography. What is the importance of a program like OCEANOS, especially in Puerto Rico? Puerto Rico is an island and surrounded by ocean, and yet there is a lack of interest in marine sciences and oceanography compared to other disciplines. So we think that we need to promote the study and also conservation of our marine resources, and to use high technology – such as remote sensing – to study and monitor our oceans and deal with things like water quality and the status of coral reefs, mangroves communities and so forth. What is something that has been rewarding about working with these students? Mostly the enthusiasm of the students when they go in the water or they look at mangroves for the first time, and learn more about their importance for fisheries and the coastline and so forth. Also sharing some of our stories and experiences in marine sciences, and listening to the students at the end of the program say that because of this experience they would like to pursue careers in marine sciences. What has been a challenge of the program? Well, one thing is the logistics, because it involves going out in boats in the ocean and there’s a limit of how many students can be in one place or in the water for safety reasons. So that that sets a limitation on the number of students for different activities. This year we started a virtual component where we are also teaching a cohort of students and teachers on the use of NASA remote sensing technology in a virtual way and they also participate in some of the projects that the in-person students developed for this project. How did you get into science? Oh, for me it was simple. I was in love with the ocean since I was a little kid. I had the opportunity of participating in what is called the ‘sea semester’ at Woods Hole Oceanographic Institution, also Boston University where I graduated, and that was a big difference. I immediately realized that that’s what I wanted to do the rest of my life. As someone born and raised in Puerto Rico, what are some of the environmental changes you’ve noticed in and around Puerto Rico? I was born in Ponce, which is the second largest city in Puerto Rico. I moved to Parguera to study marine sciences at the Department of Marine Sciences in 1976. So basically I have lived here all my life, as a student but also as a professor: this year is my 28th year as a professor of marine sciences. There were a lot of changes initially from hurricanes. In the late 1970s a couple of hurricanes destroyed huge areas of very shallow coral reef zones. After that there was a bloom of coral diseases. Through the years that has increased, decimating a lot of the coral populations in this area and in many other areas of the Caribbean and the world. More recently, in the last 5-10 years, more people in boats are coming to this area to a marine reserve, which put constant pressure on the ecosystem. When you have too many boats in one place, too many people in the water, and so forth, we don’t give the ecosystem a time to recover. What is the importance of a program like OCEANOS, particularly in Puerto Rico? We have seen that many professionals leave the island, in all disciplines. But if we can get younger people to be interested in what we do in the marine sciences in general. they will lhopefully ike to stay in Puerto Rico and work here and also make a difference in protecting our coastal ecosystems. What is something that you hope the students take with them when they leave? Even now, when the program is still going you can hear them say that the bonds they have established with fellow students and also with mentors and professors is very important. Some have also completely shifted their interest in other disciplines to marine science, or technology in general. And I’m very happy to hear that, because I think we’re having an effect on the on the people that come and the students that participate in this internship.

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) OCEANOS PI Juan Torres-Pérez, a research scientist at NASA Ames Research Center, holds two pieces of cyanobacteria in the waters of Playa Melones, Culebra Island (Puerto Rico) during the 2024 OCEANOS internship. The cyanobacteria overgrowth is likely caused by an on-land source of pollution leeching into the waters.NASA ARC/Milan Loiacono What is your name and your role with OCEANOS? My name is Juan Torres-Pérez. I am a research scientist at NASA Ames Research Center in the Earth Sciences division, biospheric sciences branch. I am the PI of OCEANOS, which stands for Ocean Community Engagement and Awareness with NASA Observations and Science for Hispanic/Latino students. What is the importance of a program like OCEANOS, particularly in Puerto Rico? When you look at the statistics in the in the US, the Hispanic/Latino community is one of the largest minorities across the continental US and jurisdictions like Puerto Rico. But in the geo sciences, the percentage of Hispanic and Latinos is very, very small, including in Puerto Rico. So that’s where we wanted to propose a project like OCEANOS: to engage Hispanic/Latino students in Puerto Rico in geosciences. Specifically, engaging students in oceanography and the use of remote sensing and NASA data to study coastal marine ecosystems. What are some of the activities that the students do as part of the program? For example here in Culebra, students study the coral reefs and their different components. What was the condition of the corals per se? The different coral species and their status. They’re also doing beach profiles, to measure whether the beaches have shrunk over time. One of the other things that they’re doing is measuring water quality in a few different sites in Culebra [Island] and also in la Parguera on the southwest coast of Puerto Rico, so they can compare the water quality in the east of Puerto Rico against the Southwest. What is something that has been rewarding about working with these students? Something rewarding is just to see their faces. Last year when they finished the program and this year as they go through the different experiences, you see how they’re learning. You see how they become engaged and how they participate in the in all the different activities. Most of the evenings, event late at night they’re still working on the data and they want to continue working with the data. So that tells you that this is something that they really enjoy and that they want to do for the future. What growth or change do you see in the students over the course of the internship? For one example, we’ve had students here that on the very first day told us that they didn’t swim, and we brought them to the water in the first week. We gave them some pointers, we talked to them about safety in the water, and taught them some techniques. And now, less than three weeks later they’re diving; they’re literally diving in the water collecting data and doing everything that we tell them to do. So that for us is a win-win situation. What has been a challenge of the program? A challenge for us is more on the on the logistics of bringing in so many students, particularly to the to the southwest coast and also to Culebra Island. These are both big tourism sites in Puerto Rico, which makes it tough for logistics like finding a place for them to stay. In the case of Culebra, we have to buy the ferry tickets to bring them to the island, the transportation and all of that. But at the end of the day it’s so rewarding that it’s definitely worth it. What is something that you hope the students take with them when they leave? We want the students to become agents of change. That means that they can pass on to their communities, their families, all their relatives, and their schools all the knowledge that they gain through this whole month, and eventually get others enthusiastic about not only engaging in activities like this, but also in preserving the ocean. We have some of the most beautiful coral reefs in the Caribbean here, and they’ve been suffering from a lot of different climate-related and anthropogenic activities. If we get them to tell others that we need to preserve this [marine ecosystem], and then they follow the same steps, that’s the long-term goal for us. What are some of the environmental changes you’ve noticed in and around Puerto Rico? One example is that nowadays there are several invasive species that have been affecting the coral reefs for at least the past couple decades and some of them even more recently. For instance, the introduction of the lionfish in the Caribbean has devastated some of the most important fish populations, such as groupers and snappers, which affects the whole food web. There are also a number of invasive seagrass species and also some other invertebrates that are literally colonizing all the areas that used to be covered by corals and the local seagrass species, and that disrupts the whole ecosystem. Many of them are a consequence of human introduction. Most of these species are actually from the Pacific, and come in or on ships as they go through the Panama canal and eventually they get into the Caribbean. Some of the larvae and such are in there, and then they find a new place to stay and reproduce. Some other species are probably related to climate change: the increase in surface temperatures the changes in currents and such. This is something that’s still being studied by a lot of scientists in the Caribbean and also in the in the Atlantic. Do you see any climate change-related effects in Puerto Rico? In particular one of the biggest changes that we have seen in terms of climate change and its impact on coral reefs is the increasing surface temperatures. We are literally going through a global coral bleaching event. That has been happening in the last in the last few years and that has affected many of the coral species in the Caribbean and many other parts in the world. Once the coral gets bleached it becomes weakened, and eventually a lot of these colonies die. Once they die they get covered by filamentous algae, and there’s no way back from there. That affects the whole ecosystem, including fisheries and others. Also, some of the coral diseases may also be triggered by these changes related to climate.

The difference in elevation between these two wheels at this location caused the drive planned on Monday, Nov. 4, 2024, to end early. Curiosity captured the image on Nov. 5, 2024, on sol 4355 — Martian day 4,355 of the Mars Science Laboratory mission — at 23:35:56 UTC. NASA/JPL-Caltech Earth planning date: Wednesday, Nov. 6, 2024 Sols 4357–4358: Turning West If you’ve ever driven down a road that’s in need of repaving, you’ll know that it can be an uncomfortable experience. The same is true on Mars: even at our carefully slow driving speed, the rough, rocky terrain that we’ve found ourselves in since entering Gediz Vallis many months ago continues to present challenges for our intrepid rover. Planning today began with the news that Curiosity only made it about halfway to its intended destination from Monday. The drive terminated early after the rover exceeded one of its “suspension limits.” This refers to our “rocker-bogie” suspension system, which allows the rover to drive over obstacles while minimizing the motion experienced by the rover body. In this case, our right middle wheel is down in a trough while the right rear wheel is perched on a rock, causing the angle of the “bogie” connecting the two wheels to exceed the maximum allowed value (Those maximums are set with a healthy amount of safety margin, so we’re not in any danger!). You can see the state of the bogie in the image above. On top of that, ending the drive early also meant that we didn’t have the images that we usually use to determine if the rover is stable enough to unstow the arm, so some creative work was necessary to determine whether or not we could. Unsurprisingly, the verdict was that we shouldn’t do so while in this awkward-looking position. As always, the team was quick to pivot to a remote sensing plan. The focus today was on getting any last-minute remote observations of the Gediz Vallis channel. This was because we decided that, rather than continuing to drive north, we would be starting our western turn toward the exit out of Gediz Vallis. The first sol of today’s plan contains a hefty two hours of science activities. These include LIBS observations of a bedrock target “North Dome” and a pair of ChemCam passive rasters of “Jewelry Lake” and “Merced River,” two smaller rocks near the rover, the latter of which appears to have been broken open as the rover drove over it. Mastcam will then take a documentation image of North Dome, as well as a mosaic of some more bedrock at “Earthquake Dome.” This first sol also includes a set of environmental science observations, including a lengthy 30-minute dust devil movie, just over 10 minutes of Navcam cloud movies, and some Navcam monitoring of dust and sand on the rover deck. We also sneak in a Navcam line-of-sight mosaic of the north crater rim, to measure the amount of dust in the air after our drive. The second sol is a fairly typical post-drive sol, beginning with a standard ChemCam AEGIS activity to let the rover autonomously select a LIBS target. The rest of the science time this sol is dedicated to environmental monitoring, including a Mastcam tau observation to monitor dust, some more Navcam deck monitoring, another Navcam cloud movie, and a 360-degree Navcam dust devil survey. No arm activities means the second sol also includes a Navcam shunt prevention activity (SPENDI) to burn off some extra power while also looking for clouds and dust devils. As always, REMS, RAD, and DAN will continue their standard activities throughout this plan. When I joined the mission back in 2020, I would occasionally look at Gediz Vallis on our HiRISE maps and imagine what the view would be like between those tall, steep channel walls. So it seems almost unbelievable that we will soon be leaving Gediz Vallis behind us as we continue our trek up Mount Sharp. It will probably still be a few more weeks before we can say that we’ve officially exited Gediz Vallis, but I don’t think anyone will be saying they were disappointed with what we accomplished during this long-anticipated phase of the mission.

Astrogram banner TIME Recognizes the Advanced Composite Solar Sail System In October, the Advanced Composite Solar Sail System a project managed at NASA Ames, was recognized by TIME Magazine as a “Top Invention of 2024”! TIME Magazine also recognized two other NASA missions this year: Europa Clipper, and the Deep Space Optical Communications experiment.   The Advanced Composite Solar Sail System is a demonstration of technologies that enable spacecraft to “sail on sunlight,” using solar radiation for propulsion. Results from this mission could provide an alternative to chemical and electric propulsion systems and guide the design of future larger-scale spacecraft for space weather early warning satellites, near-Earth asteroid reconnaissance missions, or communications relays for crewed exploration missions at the Moon and Mars. The Advanced Composite Solar Sail System a project managed at NASA Ames, was recognized by TIME Magazine as a “Top Invention of 2024.”NASA This twelve-unit (12U) CubeSat features a reflective sail held taut by composite booms made from flexible polymer and carbon fiber materials that are stiffer and lighter than previous designs. The square-shaped solar sail measures approximately 80 square meters, but the new boom technology could support future missions for solar sails up to 500 square meters.   The mission launched on April 23 via a Rocket Lab Electron rocket and met its primary objective in August by deploying the boom and sail system in space. Next, the team will attempt to demonstrate maneuverability in orbit using the sail.   Congratulations to the Advanced Composite Solar Sail System team and the Small Spacecraft Technology program office, based at Ames, for this well-earned recognition. Their contributions continue to push the boundaries of what we can achieve at NASA, and this acknowledgment highlights the capabilities and vision of our center.   Representative Anna Eshoo Recognized for 32 Years of Distinguished Public Service On Oct. 29, Ames hosted a recognition event for Representative Anna Eshoo to honor her 32 years of public service and to thank her for her enduring support for NASA and our center.

This work seeks to open the door for increased internet coverage, improved disaster response, expanded scientific missions, and even supersonic flight. The concept is referred to as an Upper-Class E traffic management, or ETM. There is currently no traffic management system or set of regulations in place for aircraft operating 60,000 feet and above. There hasn’t been a need for a robust traffic management system in this airspace until recently. That’s because commercial aircraft couldn’t function at such high altitudes due to engine constraints. NASA and partners from Aerostar and AeroVironment discuss a simulation of a high-altitude air traffic management system in the Airspace Operations Lab at NASA Ames.NASA photo by Don Richey However, recent advancements in aircraft design, power, and propulsion systems are making it possible for high- altitude, long-endurance vehicles — such as balloons, airships, and solar aircraft — to coast miles above our heads, providing radio relay for disaster response, collecting atmospheric data, and more. But before these aircraft can regularly take to the skies, operators must find a way to manage their operations without overburdening air traffic infrastructure and personnel. “We are working to safely expand high-altitude missions far beyond what is currently possible,” said Kenneth Freeman, a subproject manager for this effort at NASA’s Ames Research Center in California’s Silicon Valley. “With routine, remotely piloted high-altitude operations, we have the opportunity to improve our understanding of the planet through more detailed tracking of climate change, provide internet coverage in underserved areas, advance supersonic flight research, and more.” Current high-altitude traffic management is processed manually and on a case-by-case basis. Operators must contact air traffic control to gain access to a portion of the Class E airspace. During these operations, no other aircraft can enter this high-altitude airspace. This method will not accommodate the growing demand for high-altitude missions, according to NASA researchers. To address this challenge, NASA and its partners have developed an ETM traffic management system that allows aircraft to autonomously share location and flight plans, enabling aircraft to stay safely separated. During the recent traffic management simulation in the Airspace Operations Laboratory at Ames, data from multiple air vehicles was displayed across dozens of traffic control monitors and shared with partner computers off site. This included aircraft location, health, flight plans and more. Researchers studied interactions between a slow fixed-wing vehicle from AeroVironment and a high-altitude balloon from Aerostar operating at stratospheric heights. Each aircraft, connected to the ETM traffic management system for high altitude, shared location and flight plans with surrounding aircraft. This digital information sharing allowed Aerostar and AeroVironment high-altitude vehicle operators to coordinate and deconflict with each other in the same simulated airspace, without having to gain approval from air traffic control. Because of this, aircraft operators were able to achieve their objectives, including wireless communication relay. This simulation represents the first time a traffic management system was able to safely manage a diverse set of high-altitude aircraft operations in the same simulated airspace. Next, NASA researchers will work with partners to further validate this system through a variety of real flight tests with high-altitude aircraft in a shared airspace. The Upper-Class E traffic management concept was developed in coordination with the Federal Aviation Administration and high-altitude platform industry partners, under NASA’s National Airspace System Exploratory Concepts and Technologies subproject led out of Ames. Starship Super Heavy Breezes Through Wind Tunnel Testing at NASA Ames by Lee Mohon NASA and its industry partners continue to make progress toward Artemis III and beyond, the first crewed lunar landing missions under the agency’s Artemis campaign. SpaceX, the commercial Human Landing System (HLS) provider for Artemis III and Artemis IV, recently tested a 1.2% scale model of the Super Heavy rocket, or booster, in the transonic Unitary Plan Wind Tunnel at NASA Ames. The Super Heavy rocket will launch the Starship human landing system to the Moon as part of Artemis. A 1.2% scale model of the Super Heavy rocket that will launch the Starship human landing system to the Moon for future crewed Artemis missions was recently tested at NASA Ames’ transonic wind tunnel, providing valuable information on vehicle stability when re-entering Earth’s atmosphere.NASA During the tests, the wind tunnel forced an air stream at the Super Heavy scale model at high speeds, mimicking the air resistance and flow the booster experiences during flight. The wind tunnel subjected the Super Heavy model, affixed with pressure-measuring sensors, to wind speeds ranging from Mach .7, or about 537 miles per hour, to Mach 1.4, or about 1,074 miles per hour. Mach 1 is the speed that sound waves travel, or 761 miles per hour, at sea level. Engineers then measured how Super Heavy model responded to the simulated flight conditions, observing its stability, aerodynamic performance, and more. Engineers used the data to update flight software for flight 3 of Super Heavy and Starship and to refine the exterior design of future versions of the booster. The testing lasted about two weeks and took place earlier in 2024. After Super Heavy completes its ascent and separation from Starship HLS on its journey to the Moon, SpaceX plans to have the booster return to the launch site for catch and reuse. The Starship HLS will continue on a trajectory to the Moon. To get to the Moon for the Artemis missions, astronauts will launch in NASA’s Orion spacecraft aboard the SLS (Space Launch System) rocket from the agency’s Kennedy Space Center in Florida. Once in lunar orbit, Orion will dock with the Starship HLS or with Gateway. Once the spacecraft are docked, the astronauts will move from Orion or Gateway to the Starship HLS, which will bring them to the surface of the Moon. After surface activities are complete, Starship will return the astronauts to Orion or Gateway waiting in lunar orbit. The astronauts will transfer to Orion for the return trip to Earth. With Artemis, NASA will explore more of the Moon than ever before, learn how to live and work away from home, and prepare for future human exploration of the Red Planet. NASA’s SLS, exploration ground systems, and Orion spacecraft, along with the human landing system, next-generation spacesuits, Gateway lunar space station, and future rovers are NASA’s foundation for deep space exploration. 2024 NASA SmallSat In-Person LEARN Forum Held Audience members participate in a discussion during the 2024 NASA SmallSat Learning from Experience, Achievements, and Resolution, Navigation LEARN forum held Sept. 24 in the ballroom of Building 3 at NASA Research Park.NASA NASA Conjunction Assessment Program Officer Lauri Newman speaks at the 2024 NASA SmallSat Learning from Experience, Achievements, and Resolution, Navigation LEARN forum in the ballroom of Building 3 at NASA Research Park.NASA Attendees of the 2024 NASA SmallSat Learning from Experience, Achievements, and Resolution, Navigation LEARN forum read about other projects during the poster session in the ballroom of Building 3 at NASA Research Park.NASA NASA Astronauts, Leadership Visit Children’s Hospital, Cancer Moonshot Event NASA astronauts, scientists, and researchers, and leadership from the University of California, San Francisco (UCSF) met with cancer patients and gathered in a discussion about potential research opportunities and collaborations as part of President Biden and First Lady Jill Biden’s Cancer Moonshot initiative on Oct. 4. Roundtable discussions centered conversation around the five hazards of human spaceflight: space radiation, isolation and confinement, distance from Earth, gravity, and closed or hostile environments. Many of these hazards have direct correlations to a cancer patient’s lived experience, like the isolation of a hospital room and long-term effects of radiation.

Shown below is a test image of Earth taken by the payload camera, shortly after PTD-4 reached orbit. This camera will continue photographing the technology demonstration during the mission. Payload operations are now underway for the primary objective of the PTD-4 mission – the demonstration of a new power and communications technology for future spacecraft. The payload, a deployable solar array with an integrated antenna called the Lightweight Integrated Solar Array and anTenna, or LISA-T, has initiated deployment of its central boom structure. The boom supports four solar power and communication arrays, also called petals. Releasing the central boom pushes the still-stowed petals nearly three feet (one meter) away from the spacecraft bus. The mission team currently is working through an initial challenge to get LISA-T’s central boom to fully extend before unfolding the petals and beginning its power generation and communication operations. A test image of Earth taken by NASA’s Pathfinder Technology Demonstrator-4’s onboard camera. The camera will capture images of the Lightweight Integrated Solar Array and anTenna upon deployment.NASA Small spacecraft on deep space missions require more electrical power than what is currently offered by existing technology. The four-petal solar array of LISA-T is a thin-film solar array that offers lower mass, lower stowed volume, and three times more power per mass and volume allocation than current solar arrays. The in-orbit technology demonstration includes deployment, operation, and environmental survivability of the thin-film solar array. “The LISA-T experiment is an opportunity for NASA and the small spacecraft community to advance the packaging, deployment, and operation of thin-film, fully flexible solar and antenna arrays in space. The thin-film arrays will vastly improve power generation and communication capabilities throughout many different mission applications,” said Dr. John Carr, deputy center chief technologist at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “These capabilities are critical for achieving higher value science alongside the exploration of deep space with small spacecraft.” The Pathfinder Technology Demonstration series of missions leverages a commercial platform which serves to test innovative technologies to increase the capability of small spacecraft. Deploying LISA-T’s thin solar array in the harsh environment of space presents inherent challenges such as deploying large highly flexible non-metallic structures with high area to mass ratios. Performing experiments such as LISA-T on a smaller, lower-cost spacecraft allows NASA the opportunity to take manageable risk with high probability of great return. The LISA-T experiment aims to enable future deep space missions with the ability to acquire and communicate data through improved power generation and communication capabilities on the same integrated array. The PTD-4 small spacecraft is hosting the in-orbit technology demonstration called LISA-T. The PTD-4 spacecraft deployed into low Earth orbit from SpaceX’s Transporter-11 rocket which launched from Space Launch Complex 4E at Vandenberg Space Force Base in California on Aug. 16. NASA’s Marshall Space Flight Center in Huntsville, Alabama designed and built the LISA-T technology as well as LISA-T’s supporting avionics system. NASA’s Small Spacecraft Technology program, based at NASA’s Ames Research Center in California’s Silicon Valley and led by the agency’s Space Technology Mission Directorate, funds and manages the PTD-4 mission as well as the overall Pathfinder Technology Demonstration mission series. Terran Orbital Corporation of Irvine, California, developed and built the PTD-4 spacecraft bus, named Triumph. 2024 Silver Snoopy Awards Presented by Astronaut Nicole Mann On Oct. 24, Astronaut Nicole Mann presented the Silver Snoopy Awards in the Syvertson Auditorium at the center.

Faces of NASA – Ames’ Dr. Donald Mendoza, Chief Engineer “From my earliest childhood, flight had always captivated me. I lived out in the boonies and the farmlands, so I didn’t have neighbors to go and play with. If I wasn’t working, I was left to my own devices, and often, I would just be captivated by the wildlife and in particular, the birds of prey that I would see. Dr. Donald Menodoza, Chief Engineer, NASA Engineering and Safety Center at Ames.NASA photo by Dominic Hart “To me, they represented a freedom of some kind or another. These birds and the view they have — they can take in so much. So, from that point on, I knew I wanted to be involved in flight and aviation. “I [enjoyed] all things flight, all things spaceflight. I couldn’t get enough of it. I became an avid reader, whereas before, I wasn’t much of a reader. I couldn’t get enough material to read about my heroes from flight and space. They became my role models and the path that they took involved, at some point or another, a pretty rigorous education and dedication to doing well academically, physically, or athletically. So, I threw myself into that entire sort of mindset. “When I was working for the Air Force, I was able to fly and work on aircraft that I would dream about, looking at in the magazines Aviation Week and Space Technology. Here they are, right in front of me. “… So, my career has been as close as possible to that of a flight test engineer. And then, right on the heels of being captivated by atmospheric flight, working in human spaceflight has put me over the Moon.” —Dr. Donald Mendoza, Chief Engineer, NASA Engineering & Safety Center, NASA’s Ames Research Center Check out some of our other Faces of NASA.

We Are All Made of Cells: Space and the Immune System by Rachel Hoover Malcolm O’Malley and his mom sat nervously in the doctor’s office awaiting the results of his bloodwork. This was no ordinary check-up. In fact, this appointment was more urgent and important than the SATs the seventeen-year-old, college hopeful had spent months preparing for and was now missing in order to understand his symptoms. But when the doctor shared the results – he had off-the-charts levels of antibodies making him deathly allergic to shellfish – O’Malley realized he had more questions than answers. Like: Why is my immune system doing this? How is it working? Why is it reacting so severely and so suddenly (he’d enjoyed shrimp less than a year ago)? And why does the only treatment – an injection of epinephrine – have nothing to do with the immune system, when allergies appear to be an immune system problem? Years later, O’Malley would look to answer some of these questions while interning in the Space Biosciences Research Branch at NASA’s Ames Research Center in California’s Silicon Valley. Bone cells NASA/Eduardo Almeida and Cassie Juran “Anaphylaxis is super deadly and the only treatment for it is epinephrine; and I remember thinking, ‘how is this the best we have?’ because epinephrine does not actually treat the immune system at all – it’s just adrenaline,” said O’Malley, who recently returned to his studies as a Ph.D. student of Biomedical Engineering at the University of Virginia (UVA) in Charlottesville. “And there’s a thousand side effects, like heart attacks and stroke – I remember thinking ‘these are worse than the allergy!’” O’Malley’s curiosity and desire to better understand the mechanisms and connections between what triggers different immune system reactions combined with his interest in integrating datasets into biological insights inspired him to shift his major from computer science to biomedical engineering as an undergraduate student. With his recent allergy diagnosis and a lifelong connection to his aunt who worked at the UVA Heart and Vascular Center, O’Malley began to build a bridge between the immune system and heart health. By the time he was a senior in college, he had joined the Cardiac Systems Biology Lab, and had chosen to focus his capstone project on better understanding the role of neutrophils, a specific type of immune cell making up 50 to 70% of the immune system, that are involved in cardiac inflammation in high blood pressure and after heart attacks. “The immune system is involved in everything,” O’Malley says. “Anytime there’s an injury – a paper cut, a heart attack, you’re sick – the immune system is going to be the first to respond; and neutrophils are the first responders.” jA preflight image of beating cardiac spheroid composed of iPSC-derived cardiomyocytes (CMs), endothelial cells (ECs), and cardiac fibroblasts (CFs).

Image credit: courtesy of Drs. Joseph Wu, Dilip Thomas and Xu Cao, Stanford Cardiovascular Institute O’Malley’s work to determine what regulates the immune system’s interrelated responses – like how one cell could affect other cells or immune processes downstream – provided a unique opportunity for him to support multiple interdisciplinary NASA biological and physical sciences research projects during his 10-week internship at NASA Ames over the summer of 2024. O’Malley applied machine learning techniques to the large datasets the researchers were using from experiments and specimens collected over many years to help identify possible causes of inflammation seen in the heart, brain, and blood, as well as changes seen in bones, metabolism, the immune system, and more when humans or other model organisms are exposed to decreased gravity, social isolation, and increased radiation. These areas are of keen interest to NASA due to the risks to human health inherent in space exploration and the agency’s plans to send humans on long-duration missions to the Moon, Mars, and beyond. “It’s exciting that we just never know what’s going to happen, how the immune system is going to react until it’s already been activated or challenged in some way,” said O’Malley. “I’m particularly interested in the adaptive immune system because it’s always evolving to meet new challenges; whether it’s a pandemic-level virus, bacteria or something on a mission to Mars, our bodies are going to have some kind of adaptive immune response.” During his NASA internship, O’Malley applied a statistical analysis techniques to plot and make more sense of the massive amounts of life sciences data. From there, researchers could find out which proteins, out of hundreds, or attributes – like differences in sex – are related to which behaviors or outcomes. For example, through O’Malley’s analysis, researchers were able to better pinpoint the proteins involved in inflammation of the brain that may play a protective role in spatial memory and motor control during and after exposure to radiation – and how we might be able to prevent or mitigate those impacts during future space missions and even here on Earth. “I had this moment where I realized that since my internship supports NASA’s Human Research Program that means the work I’m doing directly applies to Artemis, which is sending the first woman and person of color to the Moon,” reflected O’Malley. “As someone who’s both black and white, representation is important to me. It’s inspiring to think there will be people like me on the Moon – and that I’m playing a role in making this happen.” When O’Malley wasn’t exploring the mysteries of the immune system for the benefit of all at NASA Ames, he taught himself how to ride a bike and started to surf in the nearby waters of the Pacific Ocean. O’Malley considers Palmyra, Virginia, his hometown and he enjoys playing sports – especially volleyball, water polo, and tennis – reading science fiction and giving guest lectures to local high school students hoping to spark their curiosity. O’Malley’s vision for the future of biomedical engineering reflects his passion for innovation. “I believe that by harnessing the unique immune properties of other species, we can achieve groundbreaking advancements in limb regeneration, revolutionize cancer therapy, and develop potent antimicrobials that are considered science fiction today,” he said.

NASA SkillBridge Veterans touring Johnson Space Center’s Neutral Buoyancy Laboratory.Credit: NASA NASA is one of America’s Best Employers for Veterans, according to Forbes and Statista. Statista surveyed more than 24,000 military veterans – having served in the United States Armed Forces – working for companies with a minimum of 1,000 employees. Veterans were asked to share opinions about their employer on factors such as working conditions, salary and pay, and topics of interest to the veteran community. This is the fourth consecutive year NASA has earned this recognition. “NASA has a long history of collaboration and commitment to the military community,” said Deborah Sweet, NASA Veterans Employment Program Manager. “In addition to the many military members who have been part of our Astronaut program, many of our civil servants are Veterans who chose to continue serving by supporting NASA’s mission after they hung up the uniform.” Across the agency, veterans deliver subject matter expertise, years of on-the-job training, and advanced skills in everything from information technology to transportation logistics and from supply-chain management to public relations. NASA continues to increase efforts to bring veterans into its ranks. The agency recently expanded its SkillBridge Fellowship Program which provides transitioning members a chance to gain valuable work experience while learning about NASA. Veterans who served on active duty and separated under honorable conditions may also be eligible for special hiring authorities such as veterans’ preference, as well as other veteran specific hiring options when applying for full time roles at NASA.

Zamani (ESA/Hubble) This NASA/ESA Hubble Space Telescope image features NGC 1672, a barred spiral galaxy located 49 million light-years from Earth in the constellation Dorado. This galaxy is a multi-talented light show, showing off an impressive array of different celestial lights. Like any spiral galaxy, shining stars fill its disk, giving the galaxy a beautiful glow. Along its two large arms, bubbles of hydrogen gas shine in a striking red light fueled by radiation from infant stars shrouded within. Near the galaxy’s center are some particularly spectacular stars embedded within a ring of hot gas. These newly formed and extremely hot stars emit powerful X-rays. Closer in, at the galaxy’s very center, sits an even brighter source of X-rays, an active galactic nucleus. This X-ray powerhouse makes NGC 1672 a Seyfert galaxy. It forms as a result of heated matter swirling in the accretion disk around NGC 1672’s supermassive black hole. See more images of NGC 1672. Image credit: ESA/Hubble & NASA, O. Fox, L. Jenkins, S.

NASA HLS (Human Landing System) Program strategic communicator and U.S. Navy Reservist Public Affairs Officer Joe Vermette brings a wealth of public service to Artemis communication activities. NASA/Ken Hall Coming from a Navy family, Vermette was inspired to military service by the example of his brother, uncles and father, who admired President John Kennedy’s call to land on the Moon and for citizens to do what they can for our country. Photo courtesy Joe Vermette While some stand on the sidelines and witness history, others are destined to play a part in it. And then there are those who document it, bringing the people, the action, the images, the words, and the personalities to the world. U. S. Navy Reservist Public Affairs Officer and program strategic communicator for NASA’s HLS (Human Landing System) Joe Vermette stands at the nexus of all three. Spurred to action to serve his country by the events of September 11, 2001; veteran of numerous overseas deployments with the Navy, and responsible for communicating NASA’s return to the Moon through the Artemis campaign, Vermette has played a part in history while he communicates humanity’s greatest endeavors to the world. Vermette joined NASA in August 2020 during the COVID-19 pandemic, coming from the Federal Emergency Management Agency (FEMA), where he was a regional communications director. Right off the bat, he rose to the challenge of learning about space exploration, Artemis, and communicating the new way the HLS Program would work with commercial providers for Moon landing services, rather than specifying spacecraft to be built. “I was used to being right in the middle of the action,” Vermette said. “The pandemic challenged me to work in a new way. At the same time, NASA and HLS were working in a new way, having just brought on our first commercial provider, SpaceX,” he said. In May 2023, the HLS Program brought on a second commercial provider, Blue Origin, for human landing services. After earning a degree in military history with a minor in communications from Florida State University, Vermette worked as a video journalist and spot writer for CNN. But it was the terrorist attacks of September 11, 2001, that really shaped his career in government service. “Three weeks later, I went down to the recruiting office and began the process of joining the military. I saw an opportunity to help the country in the best capacity I could,” Vermette said. Since then, his career has been dotted by active deployments, from the Middle East to Europe to stateside; onboard Navy ships, at U.S. Central Command, at U. S. Special Operations Command, and more. NASA’s HLS Program and Artemis have benefitted from Vermette’s experience and steady hand helping guide strategic communications since 2020. He recently answered the call to active duty again but intends to return to NASA once his military obligations are fulfilled. “NASA is a different world than the military or disaster response. But I’ve been fortunate enough to see – and communicate about – government success stories in all three arenas, Vermette said. “Seeing NASA put astronauts on the Moon again will be the best ‘mission complete’ I could have.” With Artemis, NASA will explore more of the Moon than ever before, learn how to live and work away from home, and prepare for future human exploration of the Red Planet. NASA’s SLS (Space Launch System) rocket, exploration ground systems, and Orion spacecraft, along with the human landing system, next-generation spacesuits, Gateway lunar space station, and future rovers are NASA’s foundation for deep space exploration.

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The NISAR mission will help researchers get a better understanding of how Earth’s surface changes over time, including in the lead-up to volcanic eruptions like the one pictured, at Mount Redoubt in southern Alaska in April 2009.R.G. McGimsey/AVO/USGS Data from NISAR will improve our understanding of such phenomena as earthquakes, volcanoes, and landslides, as well as damage to infrastructure. We don’t always notice it, but much of Earth’s surface is in constant motion. Scientists have used satellites and ground-based instruments to track land movement associated with volcanoes, earthquakes, landslides, and other phenomena. But a new satellite from NASA and the Indian Space Research Organisation (ISRO) aims to improve what we know and, potentially, help us prepare for and recover from natural and human-caused disasters. The NISAR (NASA-ISRO Synthetic Aperture Radar) mission will measure the motion of nearly all of the planet’s land and ice-covered surfaces twice every 12 days. The pace of NISAR’s data collection will give researchers a fuller picture of how Earth’s surface changes over time. “This kind of regular observation allows us to look at how Earth’s surface moves across nearly the entire planet,” said Cathleen Jones, NISAR applications lead at NASA’s Jet Propulsion Laboratory in Southern California. Together with complementary measurements from other satellites and instruments, NISAR’s data will provide a more complete picture of how Earth’s surface moves horizontally and vertically. The information will be crucial to better understanding everything from the mechanics of Earth’s crust to which parts of the world are prone to earthquakes and volcanic eruptions. It could even help resolve whether sections of a levee are damaged or if a hillside is starting to move in a landslide. The NISAR mission will measure the motion of Earth’s surface — data that can be used to monitor critical infrastructure such as airport runways, dams, and levees. NASA/JPL-Caltech What Lies Beneath Targeting an early 2025 launch from India, the mission will be able to detect surface motions down to fractions of an inch. In addition to monitoring changes to Earth’s surface, the satellite will be able to track the motion of ice sheets, glaciers, and sea ice, and map changes to vegetation. The source of that remarkable detail is a pair of radar instruments that operate at long wavelengths: an L-band system built by JPL and an S-band system built by ISRO. The NISAR satellite is the first to carry both. Each instrument can collect measurements day and night and see through clouds that can obstruct the view of optical instruments. The L-band instrument will also be able to penetrate dense vegetation to measure ground motion. This capability will be especially useful in areas surrounding volcanoes or faults that are obscured by vegetation. “The NISAR satellite won’t tell us when earthquakes will happen. Instead, it will help us better understand which areas of the world are most susceptible to significant earthquakes,” said Mark Simons, the U.S. solid Earth science lead for the mission at Caltech in Pasadena, California. Data from the satellite will give researchers insight into which parts of a fault slowly move without producing earthquakes and which sections are locked together and might suddenly slip. In relatively well-monitored areas like California, researchers can use NISAR to focus on specific regions that could produce an earthquake. But in parts of the world that aren’t as well monitored, NISAR measurements could reveal new earthquake-prone areas. And when earthquakes do occur, data from the satellite will help researchers understand what happened on the faults that ruptured. “From the ISRO perspective, we are particularly interested in the Himalayan plate boundary,” said Sreejith K M, the ISRO solid Earth science lead for NISAR at the Space Applications Center in Ahmedabad, India. “The area has produced great magnitude earthquakes in the past, and NISAR will give us unprecedented information on the seismic hazards of the Himalaya.” Surface motion is also important for volcano researchers, who need data collected regularly over time to detect land movements that may be precursors to an eruption. As magma shifts below Earth’s surface, the land can bulge or sink. The NISAR satellite will help provide a fuller picture for why a volcano deforms and whether that movement signals an eruption. Finding Normal When it comes to infrastructure such as levees, aqueducts, and dams, NISAR’s ability to provide continuous measurements over years will help to establish the usual state of the structures and surrounding land. Then, if something changes, resource managers may be able to pinpoint specific areas to examine. “Instead of going out and surveying an entire aqueduct every five years, you can target your surveys to problem areas,” said Jones. The data could be equally valuable for showing that a dam hasn’t changed after a disaster like an earthquake. For instance, if a large earthquake struck San Francisco, liquefaction — where loosely packed or waterlogged sediment loses its stability after severe ground shaking — could pose a problem for dams and levees along the Sacramento-San Joaquin River Delta. “There’s over a thousand miles of levees,” said Jones. “You’d need an army to go out and look at them all.” The NISAR mission would help authorities survey them from space and identify damaged areas. “Then you can save your time and only go out to inspect areas that have changed. That could save a lot of money on repairs after a disaster.” More About NISAR The NISAR mission is an equal collaboration between NASA and ISRO and marks the first time the two agencies have cooperated on hardware development for an Earth-observing mission. Managed for the agency by Caltech, JPL leads the U.S. component of the project and is providing the mission’s L-band SAR. NASA is also providing the radar reflector antenna, the deployable boom, a high-rate communication subsystem for science data, GPS receivers, a solid-state recorder, and payload data subsystem. The U R Rao Satellite Centre in Bengaluru, India, which leads the ISRO component of the mission, is providing the spacecraft bus, the launch vehicle, and associated launch services and satellite mission operations. The ISRO Space Applications Centre in Ahmedabad is providing the S-band SAR electronics. To learn more about NISAR, visit: https://nisar.jpl.nasa.gov News Media Contacts Jane J.

Dr. Annie Meier (second from left) and her team inside the Applied Chemistry Lab at NASA’s Kennedy Space Center in Florida began supplementing their normal workload in mid-2023 with efforts to improve the lab’s sustainable practices. In 2024, the laboratory became the first at NASA to receive certification from the non-profit My Green Lab for its efforts in sustainability.NASA/Kim Shiflett NASA’s Kennedy Space Center in Florida has a long record of achievements in sustainability and recently added another to the list when the spaceport’s Applied Chemistry Lab became the first in the agency to be certified for its environmentally conscious practices. The My Green Lab Certification recognizes sustainability best practices in research facilities around the world. The certification program run by My Green Lab, a non-profit dedicated to creating a culture of sustainability through science, is considered a key measure of progress towards a zero-carbon future by the United Nations Race to Zero campaign. “When I heard our lab achieved certification, I was so happy,” said Dr. Annie Meier, one of the laboratory’s chemical engineers. “It meant we could now make a conscious effort to share these green practices with all who work in our lab. We even added them to our training materials for new and incoming members in the lab.” The lab performs research and technology development for a wide range of chemistry and engineering-related applications to solve the unique operational needs of NASA and outside partners. The lab primarily focuses on in-situ resource utilization and addressing technology gaps related to lunar and Martian sustainability. The lab’s scientists also provide expertise in the fields of logistics reduction, plasma science, hypergolic fuels, analytical instrumentation, and gas analysis. While sustainability has long been a focus of the lab, the journey to the certification began when Riley Yager, a doctoral student from University of Alabama at Birmingham – where Meier was a technical monitor – shared her knowledge of the program after pursuing green lab practices at her university. “I work as a sustainability ambassador at my university, so I knew of this program,” Yager said. “Sustainable practices are something woven into my everyday life, so naturally I wanted to bring those practices into my lab environments.” After learning about the program from Yager and discovering the many other academic institutions and companies certified globally, Meier submitted a proposal to NASA and obtained funding to pursue certification for the Applied Chemistry Lab. After a kickoff event hosted by My Green Lab in April 2023, the lab’s path to certification began with a self-assessment survey, in which members of the lab answered a series of questions about their practices in areas such as cold storage, green chemistry, infrastructure energy, resource management, waste reduction, and water. My Green Lab collected and analyzed the answers, providing a baseline assessment and recommendations to improve the lab’s sustainable practices. “We took their initial survey and learned we had lots of room for improvements as a lab,” Meier said. “Then I worked with a few interns over the summer to spearhead the ‘green team’ to implement changes and get momentum from the entire lab.” The lab began with minimizing purchases by improving efficiencies during the inventory process. The team also performed a waste audit of all seven of its laboratories. They adopted nitrile glove and pipette tip box recycling, reviewed the “12 principles of green chemistry” with the lab members, and installed stickers and signage about what can and cannot be unplugged to save energy. Additionally, they installed low-flow aerators on the lab tap sinks to reduce flow, and the lab now uses a recycling sink to save on water or solvents for cleaning parts. As luck would have it, Yager ended up working at the Applied Chemistry Lab on a NASA fellowship and became a member of the green team. “It was really fun to see that come full circle,” Meier said. “Almost all members of the lab, from our fellows to most senior members, used their self-motivation to get on the sustainability train.” The green team continued to grow as the lab implemented changes to become more sustainable. Just over six months after the kickoff event, they completed another assessment survey. With possible certification levels of bronze, silver, gold, platinum, and green – the level that adheres closest to My Green Lab’s highest standards – the ACL was certified green, marking the first time any NASA center obtained a My Green Lab Certification. “Our lab is looking to sustain these green practices and achieve the same status when we are reassessed in the future,” Meier said. “This effort could be a wonderful catalyst to inspire other work groups to lean towards more ‘green’ practices at the frontline in our laboratories.” The NASA Kennedy lab joined over 2,500 labs in a range of sectors that received the My Green Lab certification. Maintaining the distinction will require recertification every two years. View the full article

Successfully deployed from the space shuttle Challenger during the February 1984 STS-41B mission, the Westar 6 and Palapa B2 communications satellites ended up in incorrect orbits due to failures of their upper stage rockets. During STS-51A in November 1984, Discovery’s second trip into space, the crew of Commander Frederick H. “Rick” Hauck, Pilot David M. Walker, and Mission Specialists Joseph P. Allen, Anna L. Fisher, and Dale A. Gardner worked as a team to not only deploy two new satellites but also to retrieve the two wayward but otherwise healthy satellites for return to Earth. Hauck and Walker piloted Discovery to rendezvous with each satellite in turn, Allen and Gardner retrieved them during two spacewalks, and Fisher grappled and placed them in the payload bay for return to Earth. After refurbishment, both satellites returned to space. Left: The STS-51A crew of Dale A. Gardner, left, David M. Walker, Anna L. Fisher, Frederick “Rick” H. Hauck, and Joseph P. Allen. Right: The STS-51A crew patch. NASA originally designated Hauck, Walker, Allen, Fisher, and Gardner as a crew in November 1983 and assigned them to STS-41H, a mission aboard Challenger planned for late September 1984 to either deploy the second Tracking and Data Relay Satellite (TDRS) or fly a classified payload for the Department of Defense. Due to ongoing problems with the Inertial Upper Stage that failed to put the first TDRS satellite in its correct orbit during STS-6, NASA canceled STS-41H and shifted Hauck’s crew to STS-51A. In February 1984, an agreement between NASA and the Canadian government added an as-yet unnamed Canadian payload specialist to the STS-51A crew. Managers later named the Canadian as Marc Garneau and reassigned him to STS-41G. A shuffling of payloads following the STS-41D launch abort resulted in STS-51A now deploying the Anik D2 satellite for Canada and Leasat 1 (also known as Syncom IV-1) for the U.S. Navy. By early August, the launch date had slipped to Nov. 2, with NASA considering the possibility of retrieving the two wayward satellites from STS-41B, officially adding that task on Aug. 13. NASA selected Allen in 1967 as one of 11 scientist-astronauts, while the rest of the crew hail from the Class of 1978. Hauck, on his second mission after serving as pilot on STS-7, has the distinction as the first from his class to command a shuttle mission. Allen and Gardner had each flown one previous mission, STS-5 and STS-8, respectively, while for Walker and Fisher STS-51A represented their first flight. Fisher has the distinction as the first mother in space.

Middle: Workers lift Discovery to stack it with the ET and SRBs. Right: The completed stack prepares to leave the VAB for the rollout to Launch Pad 39A. Discovery arrived back at NASA’s Kennedy Space Center (KSC) in Florida on Sept. 10, returning from Edwards Air Force Base in California following the STS-41D mission. Workers towed it to the Orbiter Processing Facility (OPF) the next day to begin the process of refurbishing it for STS-51A. On Oct. 18, they rolled it over to the Vehicle Assembly Building (VAB), for stacking with an External Tank and twin Solid Rocket Boosters. At NASA’s Kennedy Space Center in Florida, space shuttle Discovery rolls out to Launch Pad 39A, with the Saturn V rocket on display in the foreground. The completed stack rolled out to Launch Pad 39A on Oct. 23. Two days later, the five-member STS-51A crew participated in the Terminal Countdown Demonstration Test, essentially a dress rehearsal for the actual countdown to launch. The crew returned to KSC on Nov. 5, the day the countdown began for a planned Nov. 7 launch. High upper-level winds that day forced a one-day delay. Left: STS-51A astronaut Dale A. Gardner trains for the capture of a satellite using the Apogee Kick Motor Capture Device. Middle: Astronaut Anna L. Fisher trains to use the Canadian-built Remote Manipulator System, or robotic arm. Right: As part of the Terminal Countdown Demonstration Test, the STS-51A astronauts practice rapid evacuation from the launch pad. Following deployment from Challenger during STS-41B, the upper stages of both the Westar 6 and Palapa B2 satellites malfunctioned, leaving them in non-useable 160-by-600-mile-high orbits instead of the intended 22,300-mile-high geostationary orbits required for their normal operations. While both satellites remained healthy, their own thrusters could not boost them to the proper orbits. NASA devised a plan to have astronauts retrieve the satellites during spacewalks using the jetpack known as the Manned Maneuvering Unit (MMU), after which the shuttle’s Canadian-built Remote Manipulator System (RMS) or robot arm would grapple them and place them into the cargo bay for return to Earth. Astronauts had demonstrated the capability of the MMU during the STS-41C Solar Max satellite repair mission in April 1984 and NASA felt confident of its ability to capture and return Westar and Palapa. In the weeks prior to STS-51A, ground controllers lowered the orbits of both satellites and reduced their spin rates from 50 to 1 rpm to enable capture by the shuttle astronauts. Engineers at NASA’s Johnson Space Center in Houston developed the Apogee Kick Motor Capture Device (ACD), otherwise known as the stinger due to its appearance, to allow an astronaut to capture the satellites while flying the MMU. Once relocated over the payload bay, a second astronaut would remove the satellite’s omnidirectional antenna with pruning shears and install an Antenna Bridge Structure (ABS) with a grapple fixture over the satellite’s main antenna dish. Allen would fly the MMU to capture Palapa, then he would switch roles with Gardner who would capture Westar. Fisher would use the RMS to grapple the satellites by this second fixture and lower them into specially built cradles to secure them into the payload bay.

Right: View inside Discovery’s payload bay shortly after orbital insertion – the top of Anik D2 is visible, with Leasat 1 hidden behind it. Space shuttle Discovery roared off KSC’s Launch Pad 39A on Nov. 8, 1984, to begin the STS-51A mission and mark the orbiter’s first return to space. For Gardner, launch day coincided with his 36th birthday. The launch took place just 26 days after the landing of the previous mission, STS-41G, a then record-breaking turnaround time between shuttle flights. Eight and a half minutes after liftoff, Discovery and its five-member crew reached space and shortly thereafter settled into a 182-by-172-mile-high initial orbit. As their first order of business, the crew checked out the RMS to ensure its functionality for the satellite captures later in the mission. They also performed the first rendezvous burn to begin the approach to the Palapa satellite. The crew then settled down for its first night’s sleep in orbit. Left: Nighttime deploy of the Anik D2 satellite. Middle: Deploy of the Leasat 1 satellite. Right: Leasat 1 as it departs from Discovery. The primary activity of the second flight day involved Allen deploying the 2,727-pound Anik D2 satellite via a spring ejection mechanism, occurring on time and with no issues. The crew also circularized the shuttle’s orbit at 186 miles. The next day, Gardner deployed the 17,000-pound Leasat 1 using the Frisbee style mechanism used to deploy the first Leasat during STS-41D two months earlier. With the satellite deployments complete, the crew began to focus on the rendezvous maneuvers to bring them close to the Palapa B2 satellite while Allen and Gardner verified the functionality of their spacesuits. On flight day 4, the astronauts reduced the pressure inside the shuttle from 14.7 pounds per square inch (psi) to 10.2 psi in order to prevent the spacewalking astronauts from developing the bends inside the spacesuits that operated at 4.3 psi. Left: During the first spacewalk, Jospeh P. Allen captures the Palapa B2 satellite. Middle: Anna L. Fisher grasps Allen and Palapa with the Remote Manipulator System, or robotic arm. Right: Allen, left, and Dale A. Gardner prepare to place Palapa in its cradle in the payload bay. On the fifth mission day, after Hauck and Walker piloted Discovery to within 35 feet of Palapa, Allen and Gardner exited the airlock to begin the spacewalk portion of the satellite capture. Allen donned the MMU mounted on the side wall of the cargo bay, attached the stinger to its arms, and flew out to Palapa. Once there, he inserted the stinger into the satellite’s Apogee Kick Motor bell and using the MMU’s attitude control system stopped Palapa’s spin. Fisher then steered the RMS to capture a grapple fixture mounted on the stinger between Allen and the satellite. She then maneuvered them over the payload bay where Gardner waited to remove its omnidirectional antenna and install the bridge structure. However, Gardner could not attach the ABS to the satellite due to an unexpected clearance issue on the satellite. Using a backup plan, Allen undocked from the stinger, leaving it attached to the satellite as well as the RMS, and stowed the MMU in the payload bay. With Allen now holding the satellite by its antenna, Gardner attached an adaptor to the bottom end of the satellite to secure it in its cradle in the payload bay. This plan worked and Allen and Gardner completed the spacewalk in exactly six hours. Left: Dale A. Gardner flies the Manned Maneuvering Unit to capture Westar 6 during the second spacewalk. Middle: Anna L. Fisher operates the Remote Manipulator System from Discovery’s aft flight deck. Right: Gardner, left, and Joseph P. Allen maneuver Westar prior to placing it in its cradle in the payload bay. Between the two spacewalk days, the crew serviced the spacesuits, conducted routine maintenance on the shuttle, and prepared for the second rendezvous, this time to retrieve Westar. Allen and Gardner switched roles for the second spacewalk on flight day seven, with Gardner flying the MMU to capture Westar. The astronauts repeated the procedure from the first spacewalk, except for not removing the omni antenna so they could use it as a handhold. With Westar secured in the payload bay, Gardner and Allen completed the second spacewalk in 5 hours and 42 minutes. Left: Dale A. Gardner, left, and Joseph P.

Right: View inside Discovery’s payload bay shortly before the deorbit burn, with Westar 6 in the foreground and Palapa B2 behind it. During their final full day in space, Discovery’s crew repressurized the shuttle’s cabin to 14.7 psi and tidied the cabin in preparation for reentry. On Nov. 16, the astronauts closed the payload bay doors and fired the Orbital Maneuvering System engines to begin the descent back to Earth. Hauck guided Discovery to a smooth landing at KSC, completing a flight of 7 days, 23 hours, and 45 minutes. The crew had traveled nearly 3.3 million miles and completed 127 orbits around the Earth. The next day, workers towed Discovery to the OPF to begin preparing it for its next flight, STS-51C in January 1985.

Right: NASA officials greet the STS-51A astronauts as they exit Discovery. As a postscript, STS-51A marked the last flight to use the MMUs, and the last untethered spacewalks until 1994 when STS-64 astronauts tested the Simplified Aid for EVA Rescue (SAFER). All subsequent spacewalks on the space shuttle and the International Space Station used safety tethers, with the SAFER as a backup in case a crew member disconnects from the vehicle.

Right: The STS-51A crew, with Lloyd’s of London representative Stephen Merritt, sitting at right, during their visit to London. On Dec. 7, 1984, in a ceremony at the White House, President Ronald W. Reagan presented the STS-51A crew with the Lloyd’s of London – the company had insured the two satellites they returned to Earth – Silver Medal for Meritorious Salvage Operations. Fisher has the distinction as only the second woman to receive that award. In February 1985, Lloyd’s flew the crew to London on the Concorde for a week of activities, including addressing the Lloyd’s underwriters and tea with Prince Charles at Kensington Palace. Hong Kong-based AsiaSat purchased the Westar 6 satellite, refurbished it, and relaunched it as AsiaSat 1 on April 7, 1990, on a Chinese CZ-3 rocket. Title to the Palapa B2 satellite returned to Indonesia after its relaunch as Palapa B2R on April 13, 1990, aboard a Delta rocket.
