When the asteroid Psyche has its first close-up with a NASA spacecraft, scientists hypothesize they will find a metal-rich asteroid. It could be part or all of the iron-rich interior of a planetesimal, an early planetary building block, that was stripped of its outer rocky shell as it repeatedly collided with other large bodies during the early formation of the solar system. New research from scientists at NASA’s Ames Research Center in California’s Silicon Valley suggests that is exactly what the agency’s Psyche mission will find. An artist’s concept depicting the metal-rich asteroid Psyche, which is located in the main asteroid belt between Mars and Jupiter. NASA/JPL-Caltech/ASU Led by Anicia Arredondo, the paper’s first author and a postdoctoral researcher at the Southwest Research Institute in San Antonio, Texas, and Maggie McAdam, Ames research scientist and principal investigator, the team observed Psyche in Feb. 2022 using NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA). The now-retired observatory was a Boeing 747SP aircraft modified to carry a reflecting telescope. As a flying telescope, SOFIA collected data that was not affected by Earth’s lower atmosphere and made observations from all over the world, including over the oceans. For the first time, SOFIA was able to gather data from every part of Psyche’s surface. It also allowed the team to collect data about the materials that make up Psyche’s surface – information that could not be gathered from ground-based telescopes. Psyche’s potential to answer many questions about planet formation is a key reason why it was selected for close observation by a spacecraft. Scientists believe that planets like Earth, Mars, and Mercury have metallic cores, but they are buried too far below the planets’ mantles and crusts to see or measure directly. If Psyche is confirmed to be a planetary core, it can help scientists understand what is inside the Earth and other large planetary bodies. Psyche’s size is also important for advancing scientific understanding of Earth-like planets. It is the largest M-type (metallic) asteroid in our solar system and is long enough to cover the distance from New York City to Baltimore, Maryland. This means Psyche is more likely to show differentiation, which is when the materials inside a planet separate from one another, with the heaviest materials sinking to the middle and forming cores. “Every time a new study of Psyche is published, it raises more questions,” said Arredondo, who was a postdoctoral researcher at Ames on the SOFIA mission when the Psyche observations were collected. “Our findings suggest the asteroid is very complex and likely holds many other surprises. The possibility of the unexpected is one of the most exciting parts of a mission to study an unexplored body, and we look forward to gaining a more detailed understanding of Psyche’s origins.” NASA’s Psyche spacecraft is shown in a clean room on June 26, 2023, at the Astrotech Space Operations facility near the agency’s Kennedy Space Center in Florida.NASA/Frank Michaux More about the Psyche and SOFIA missions: Arizona State University leads the Psyche mission. A division of Caltech in Pasadena, JPL is responsible for the mission’s overall management, system engineering, integration and test, and mission operations. Maxar Technologies in Palo Alto, California, provided the high-power solar electric propulsion spacecraft chassis. Psyche is the 14th mission selected as part of NASA’s Discovery Program, managed by the agency’s Marshall Space Flight Center in Huntsville, Alabama. NASA’s Launch Services Program, based at Kennedy, is managing the launch service. SOFIA was a joint project of NASA and the German Space Agency at DLR. DLR provided the telescope, scheduled aircraft maintenance, and other support for the mission. NASA’s Ames Research Center in California’s Silicon Valley managed the SOFIA program, science, and mission operations in cooperation with the Universities Space Research Association, headquartered in Columbia, Maryland, and the German SOFIA Institute at the University of Stuttgart. The aircraft was maintained and operated by NASA’s Armstrong Flight Research Center Building 703, in Palmdale, California. SOFIA achieved full operational capability in 2014 and concluded its final science flight on Sept. 29, 2022.

The National Aeronautics and Space Administration (NASA) was created on October 1, 1958, to perform civilian research related to space flight and aeronautics. President Eisenhower commissioned Dr. T. Keith Glennan, right, as the first administrator for NASA and Dr. Hugh L. Dryden as deputy administrator.NASA On July 29, 1958, President Dwight D. Eisenhower signed the National Aeronautics and Space Act “to provide for research into problems of flight within and outside the Earth’s atmosphere.” At the White House less than a month later, Eisenhower commissioned Dr. T. Keith Glennan, right, as the first administrator for NASA and Dr. Hugh L. Dryden as deputy administrator. NASA officially opened for business 65 years ago on Oct. 1, 1958, to oversee the United States’ nonmilitary space activities. It was based on its predecessor, the National Advisory Committee for Aeronautics, which was established in 1915 to “supervise and direct the scientific study of the problems of flight, with a view to their practical solution.” Learn more about the creation of NASA.

NASA astronaut Scott Kelly took this majestic image of the Earth at night highlighting the green and red hues of an Aurora. NASA NASA is asking American companies to provide input on the agency’s requirements for end-to-end services as part of the Commercial Low-Earth Orbit Development Program. In the future, the agency plans to transition its operations in low Earth orbit to commercially owned and operated destinations to ensure continued access and presence in space for research, technology development, and international collaboration after the planned retirement of the International Space Station. Through a request for information (RFI), NASA is seeking feedback from industry as the agency refines its anticipated requirements for new commercial space destinations. The requirements will help industry understand NASA’s human-rating standards that will be used by the agency to certify that the new systems meet NASA expectations for low Earth orbit operations and transportation. An industry briefing day is scheduled to take place Tuesday Oct. 12, with responses to the RFI due Wednesday, Nov. 17. “This RFI is a significant next step in transitioning low Earth orbit operations to the private sector, allowing NASA to be one of many customers for services” says Phil McAlister, director of commercial spaceflight at NASA Headquarters in Washington, D.C. “These requirements will be the foundation upon which the companies can design safe systems. But the requirements have to work for companies as well. Thus, we are seeking industry feedback on these draft requirements to ensure that the Commercial LEO destinations will be safe, reliable, and cost effective.” The agency is currently supporting the development of several new stations and destination concepts through both funded and unfunded agreements. However, a company does not need to have a current agreement with NASA in order to provide feedback via the RFI or to bid on future procurements to provide low Earth orbit services to the agency. “We’ve seen a tremendous amount of innovation and effort from industry thus far in developing their station designs,” says Angela Hart, manager of the Commercial Low Earth Orbit Development program at NASA’s Johnson Space Center in Houston. “We are working in lockstep with multiple companies to help guide them in a way that sets them up for success to meet our requirements. However, it’s crucial that we open feedback to as wide of an audience as possible. The more commercial stations that are successfully operating in low Earth orbit, the greater likelihood that we can continue to drive down costs and encourage innovation in this new commercial space industry.” NASA previously sought industry input in 2022 and early 2023, and has hosted two industry days on the agency’s assumptions and expectations for crew and technical requirements to guide companies’ technical and business plans. The feedback from industry will continue to inform the agency’s future commercial services strategy for low Earth orbit destinations. NASA’s goal is to enable a strong commercial marketplace in low Earth orbit where NASA is one of many customers for private industry. This strategy will provide services the government needs safely, at a lower cost, and enables the agency to focus on its Artemis missions to the Moon in preparation for Mars, while continuing to use low Earth orbit as a training and proving ground for those deep space missions. Information about how to attend the industry briefing day is contained in the RFI on SAM.gov. The dates for industry day and responses due are subject to change pending a government shutdown resolution and will be updated on SAM.gov when available.

2 min read Hubble Views A Vibrant Virgo Cluster Galaxy NASA’s Hubble Space Telescope, ESA, and J. Lee (Space Telescope Science Institute); Processing: Gladys Kober (NASA/Catholic University of America) It’s easy to get swept up in the swirling starry arms of this intermediate spiral galaxy, NGC 4654, in the constellation Virgo. The galaxy has a bright center and is labeled “intermediate” because it has characteristics of both unbarred and barred spirals. NGC 4654 is just north of the celestial equator, making it visible from the northern hemisphere and most of the southern hemisphere. The galaxy is around 55 million light-years from Earth. NGC 4654 is one of many Virgo Cluster galaxies that have an asymmetric distribution of stars and of neutral hydrogen gas. Astronomers reason that NGC 4654 may be experiencing a process called “ram pressure stripping,” where the gravitational pull of the Virgo galaxy cluster puts pressure on NGC 4654 as it moves through a superheated plasma made largely of hydrogen called the “intracluster medium.” This pressure feels like a gust of wind – think of a biker feeling wind even on a still day – that strips NGC 4654 of its gas. This process produced a long, thin tail of hydrogen gas on the galaxy’s southeastern side. Most galaxies that experienced ram pressure stripping hold very little cold gas, halting the galaxy’s ability to form new stars, since stars generate from dense gas. However, NGC 4654 has star formation rates consistent with other galaxies of its size. NGC 4654 also had an interaction with the companion galaxy NGC 4639 about 500 million years ago. The gravity of NGC 4639 stripped NGC 4654’s gas along its edge, limiting star formation in that region and causing the asymmetrical distribution of the galaxy’s stars. Scientists study galaxies like NGC 4654 to examine the connection between young stars and the cold gas from which they form. NASA’s Hubble Space Telescope took this image in visible, ultraviolet, and infrared light.

Discovery Alert: The Planet that Shouldn’t Be There Artist’s rendering of planet 8 Ursae Minoris b – also known as “Halla” – amid the field of debris after a violent merger of two stars. The planet might have survived the merger, but also might be an entirely new planet formed from the debris. W. M. Keck Observatory/Adam Makarenko By Pat Brennan NASA’s Exoplanet Exploration Program The discovery: A large planet is somehow orbiting a star that should have destroyed it. Key facts: Planet 8 Ursae Minoris b orbits a star some 530 light-years away that is in its death throes. A swollen red giant, the star would have been expected to expand beyond the planet’s orbit before receding to its present (still giant) size. In other words, the star would have engulfed and ripped apart any planets orbiting closely around it. Yet the planet remains in a stable, nearly circular orbit. The discovery of this seemingly impossible situation, relying on precise measurements using NASA’s Transiting Exoplanet Survey Satellite (TESS), shows that planet formation – and destruction – are likely far more intricate and unpredictable than many scientists might have thought. Details: As stars like our Sun approach the ends of their lives, they begin to exhaust their nuclear fuel. They become red giants, expanding to their maximum size. If that happened in this case, the star would have grown outward from its center to 0.7 astronomical units – that is, about three-quarters the distance from Earth to the Sun. It would have swallowed and destroyed any nearby orbiting planets in the process. But planet b, a large gaseous world, sits at about 0.5 astronomical units, or AU. Because the planet could not have survived engulfment, Marc Hon, the lead author of a recent paper on the discovery, instead proposes two other possibilities: The planet is really the survivor of a merger between two stars, or it’s a new planet – formed out of the debris left behind by that merger. The first scenario begins with two stars about the size of our Sun in close orbit around each other, the planet orbiting both. One of the stars “evolves” a bit faster than the other, going through its red giant phase, casting off its outer layers and turning into a white dwarf – the tiny but high-mass remnant of a star. The other just reaches the red giant stage before the two collide; what remains is the red giant we see today. This merger, however, stops the red giant from expanding further, sparing the orbiting planet from destruction. In the second scenario, the violent merger of the two stars ejects an abundance of dust and gas, which forms a disk around the remaining red giant. This “protoplanetary” disk provides the raw material for a new planet to coalesce. It’s a kind of late-stage second life for a planetary system – though the star still is nearing its end. Fun facts: How can astronomers infer such a chaotic series of events from present-day observations? It all comes down to well understood stellar physics. Planet-hunting TESS also can be used to observe the jitters and quakes on distant stars, and these follow known patterns during the red-giant phase. (Tracking such oscillations in stars is known as “asteroseismology.”) The pattern of oscillations on 8 Ursae Minoris, the discovery team found, match those of red giants at a late, helium-burning stage – not one that is still expanding as it burns hydrogen. So it isn’t that the star is still growing and hasn’t yet reached the planet. The crisis has come and gone, but the planet somehow continues to exist. The discoverers: The paper describing the TESS result, “A close-in giant planet escapes engulfment by its star,” was published in the journal Nature in June 2023 by an international science team led by astronomer Marc Hon of the University of Hawaii.

NASA logoCredits: NASA NASA has selected four small explorer missions to conduct concept studies. These studies aim to expand knowledge of the dynamics of the Sun and related phenomena, such as coronal mass ejections, aurora, and solar wind to better understand the Sun-Earth connection. Any missions selected to move forward after the concept studies are conducted will join the current heliophysics mission fleet, which not only provides deeper insight into the mechanics of our universe, but also offers critical information to help protect astronauts, satellites, and communications signals, and helps enable space exploration. “These four mission concept studies were selected because they address compelling science questions and could greatly impact the field of heliophysics,” said Nicky Fox, the associate administrator for science at NASA Headquarters in Washington. “These mission proposals are exciting because they build upon and complement the science of our current mission fleet, have the potential for broad impact and could provide new and deeper insight into the solar atmosphere and space weather.” CINEMA The Cross-scale Investigation of Earth’s Magnetotail and Aurora (CINEMA) mission would work to understand the structure and evolution of Earth’s plasma sheet – a long sheet of denser space plasma in the magnetic fields flowing behind Earth, known as the magnetotail — using a constellation of nine CubeSats flown in sun-synchronous, low Earth orbit. The primary purpose of this mission is to study the role of plasma sheet structure, as well as how Earth’s magnetic fields transfer heat and change over time at multiple scales. CINEMA will complement current heliophysics missions, such as the THEMIS (Time History of Events and Macroscale Interactions during Substorms), MMS (Magnetospheric Multiscale) mission, and the planned Geospace Dynamics Constellation mission. The principal investigator for the CINEMA mission concept study is Robyn Millan from Dartmouth College, in Hanover, New Hampshire. CMEx The Chromospheric Magnetism Explorer (CMEx) mission would attempt to understand the magnetic nature of solar eruptions and identify the magnetic sources of the solar wind. CMEx proposes to obtain the first continuous observations of the solar magnetic field in the chromosphere – the layer of solar atmosphere directly above the photosphere or visible surface of the Sun. These observations would improve our understanding of how the magnetic field on the Sun’s surface connects to the interplanetary magnetic field. The principal investigator for this mission concept study is Holly Gilbert from the National Center for Atmospheric Research in Boulder, Colorado. EUV CME and Coronal Connectivity Observatory The Extreme ultraviolet Coronal Mass Ejection and Coronal Connectivity Observatory (ECCCO) consists of a single spacecraft with two instruments, a wide-field extreme ultra-violet imager and a unique imaging EUV spectrograph. ECCCO’s observations would contribute to understanding the middle corona, the dynamics of eruptive events leaving the Sun, and the conditions that produce the outward streaming solar wind. The mission would address fundamental questions about where the mass and energy flow linking the Sun to the outer corona and heliosphere originate ECCCO’s concept study principal investigator is Katharine Reeves from the Smithsonian Astrophysical Observatory, in Cambridge, Massachusetts. MAAX The primary objective of the Magnetospheric Auroral Asymmetry Explorer (MAAX) mission would be to improve our understanding of how electrodynamic coupling between Earth’s magnetosphere and ionosphere regulates auroral energy flow. The mission would use two identical spacecraft equipped with dual-wavelength ultraviolet imagers to provide global imaging of northern and southern aurora. The principal investigator for the MAAX concept study is Michael Liemohn from the University of Michigan in Ann Arbor. “These mission concept study selections provide so much promise to ongoing heliophysics research,” said Peg Luce, acting Heliophysics division director at NASA Headquarters. “The potential to gain new insights and answer longstanding questions in the field while building on the research and technology of our current and legacy missions is incredible..” Funding and management oversight for these mission concept studies is provided by the Heliophysics Explorers Program, managed by the Explorers Program Office at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

SpaceX’s Dragon will deliver new science investigations, food, supplies, and equipment to the international crew. The research includes work to understand interactions between weather on Earth and space, and laser communications. NASA’s Atmospheric Waves Experiment (AWE) will study atmospheric gravity waves –powerful waves formed by weather disturbances on Earth such as strong thunderstorms or brewing hurricanes – to understand the flow of energy through Earth’s upper atmosphere and space. Another experiment – Integrated Laser Communications Relay Demonstration Low-Earth-Orbit User Modem and Amplifier Terminal – (ILLUMA-T) aims to test high data rate laser communications from the space station to Earth. This will complete NASA’s first two-way, end-to-end laser relay system by sending high-resolution data to the agency’s Laser Communications Relay Demonstration, which launched in December 2021. Other investigations that will launch with the resupply mission include ESA’s (European Space Agency) Aquamembrane-3, which will test water filtration using proteins found in nature for water recycling and recovery, and Plant Habitat-06, which will evaluate the effects of spaceflight on plant defense responses using multiple genotypes of tomato. Commercial resupply by U.S. companies significantly increases NASA’s ability to conduct more investigations aboard the orbiting laboratory. These investigations lead to new technologies, medical treatments, and products that improve life on Earth. Other U.S. government agencies, private industry, and academic and research institutions can also conduct microgravity research through the agency’s partnership with the International Space Station National Laboratory. Humans have occupied the space station continuously since November 2000. In that time, 273 people and a variety of international and commercial spacecraft have visited the orbital outpost. It remains the springboard to NASA’s next great leap in exploration, including future missions to the Moon under Artemis, and ultimately, human exploration of Mars.

5 min read To Study Atmosphere, NASA Rockets Will Fly into Oct. Eclipse’s Shadow A NASA sounding rocket mission will launch three rockets during the 2023 annular eclipse in October to study how the sudden drop in sunlight affects our upper atmosphere. On Oct. 14, 2023, viewers of an annular solar eclipse in the Americas will experience the Sun dimming to 10% its normal brightness, leaving only a bright “ring of fire” of sunlight as the Moon eclipses the Sun. Those in the vicinity of the White Sands Missile Range in New Mexico, however, might also notice sudden bright streaks across the sky: trails of scientific rockets, hurtling toward the eclipse’s shadow. A NASA sounding rocket mission will launch three rockets to study how the sudden drop in sunlight affects our upper atmosphere. The mission, known as Atmospheric Perturbations around the Eclipse Path or APEP, is led by Aroh Barjatya, a professor of engineering physics at Embry-Riddle Aeronautical University in Daytona Beach, Florida, where he directs the Space and Atmospheric Instrumentation Lab. Some 50 miles up and beyond, the air itself becomes electric. Scientists call this atmospheric layer the ionosphere because it is where the UV component of sunlight can pry electrons away from atoms to form a sea of high-flying ions and electrons. The Sun’s constant energy keeps these mutually attracted particles separated throughout the day. But as the Sun dips below the horizon, many recombine into neutral atoms for the night, only to part ways again at sunrise. During a solar eclipse, the sunlight vanishes and reappears over a small part of the landscape almost at once. In a flash, ionospheric temperature and density drop, then rise again, sending waves rippling through the ionosphere. “If you think of the ionosphere as a pond with some gentle ripples on it, the eclipse is like a motorboat that suddenly rips through the water,” Barjatya said. “It creates a wake immediately underneath and behind it, and then the water level momentarily goes up as it rushes back in.” The animation shows the changes in the number of electrons (total electron content or TEC) in the ionosphere over the US during the 2017 eclipse. Overlaid on the measurements are the contours that represent location of the outer shadow of the eclipse as it moves across the sky. Credit: Mrak, S., Semeter, J., Drob, D., & Huba, J. D. (2018).

So did critical infrastructure like GPS and communications satellites that we rely on every day. “All satellite communications go through the ionosphere before they reach Earth,” Barjatya said. “As we become more dependent on space-based assets, we need to understand and model all perturbations in the ionosphere.” Aroh Barjatya, of Embry-Riddle Aeronautic University in Daytona Beach, Florida, leads the APEP mission.

It was said that Apep pursued Ra and every so often nearly consumed him, resulting in an eclipse. The APEP team plans to launch three rockets in succession – one about 35 minutes before local peak eclipse, one during peak eclipse, and one 35 minutes after. They will fly just outside the path of annularity, where the Moon passes directly in front of the Sun. Each rocket will deploy four small scientific instruments that will measure changes in electric and magnetic fields, density, and temperature. If they are successful, these will be the first simultaneous measurements taken from multiple locations in the ionosphere during a solar eclipse. Barjatya chose sounding rockets to answer the team’s science questions because they can pinpoint and measure specific regions of space with high fidelity. They can also measure changes that happen at different altitudes as the suborbital rocket ascends and falls back to Earth. The APEP rockets will take measurements between 45 and 200 miles (70 to 325 kilometers) above the ground along their trajectory. “Rockets are the best way to look at the vertical dimension at the smallest possible spatial scales,” said Barjatya. “They can wait to launch at just the right moment and explore the lower altitudes where satellites can’t fly.” While the in-situ rocket instruments are all being built by Embry-Riddle and Dartmouth College in New Hampshire, a host of ground-based observations will also support the mission. Co-investigators from the Air Force Research Laboratory at Kirtland Air Force Base in Albuquerque, New Mexico, will collect ionospheric density and neutral wind measurements. Co-investigators from the Massachusetts Institute of Technology’s Haystack Observatory in Westford, Massachusetts, will run their radar to measure ionospheric perturbations farther away from the eclipse path. Finally, a team of students from Embry-Riddle will deploy high-altitude balloons (reaching 100,000 feet) every 20 minutes to measure weather changes as the eclipse passes by. All of these measurements will aid ionosphere modeling efforts led by scientists at the University of Colorado Boulder and Embry-Riddle. This won’t be the only APEP launch. The APEP rockets launched in New Mexico will be recovered and then relaunched from NASA’s Wallops Flight Facility in Virginia, on April 8, 2024, when a total solar eclipse will cross the U.S. from Texas to Maine. The April launches are farther from the eclipse path than for the October annular eclipse, but will present an opportunity to measure just how widespread the effects of an eclipse are.

5 min read To Study Atmosphere, NASA Rockets Will Fly into Oct. Eclipse’s Shadow On Oct. 14, 2023, viewers of an annular solar eclipse in the Americas will experience the Sun dimming to 10% its normal brightness, leaving only a bright “ring of fire” of sunlight as the Moon eclipses the Sun. Those in the vicinity of the White Sands Missile Range in New Mexico, however, might also notice sudden bright streaks across the sky: trails of scientific rockets, hurtling toward the eclipse’s shadow. A NASA sounding rocket mission will launch three rockets to study how the sudden drop in sunlight affects our upper atmosphere. The mission, known as Atmospheric Perturbations around the Eclipse Path or APEP, is led by Aroh Barjatya, a professor of engineering physics at Embry-Riddle Aeronautical University in Daytona Beach, Florida, where he directs the Space and Atmospheric Instrumentation Lab. Some 50 miles up and beyond, the air itself becomes electric. Scientists call this atmospheric layer the ionosphere because it is where the UV component of sunlight can pry electrons away from atoms to form a sea of high-flying ions and electrons. The Sun’s constant energy keeps these mutually attracted particles separated throughout the day. But as the Sun dips below the horizon, many recombine into neutral atoms for the night, only to part ways again at sunrise. During a solar eclipse, the sunlight vanishes and reappears over a small part of the landscape almost at once. In a flash, ionospheric temperature and density drop, then rise again, sending waves rippling through the ionosphere. “If you think of the ionosphere as a pond with some gentle ripples on it, the eclipse is like a motorboat that suddenly rips through the water,” Barjatya said. “It creates a wake immediately underneath and behind it, and then the water level momentarily goes up as it rushes back in.” The animation shows the changes in the number of electrons (total electron content or TEC) in the ionosphere over the US during the 2017 eclipse. Overlaid on the measurements are the contours that represent location of the outer shadow of the eclipse as it moves across the sky.Credit: Mrak, S., Semeter, J., Drob, D., & Huba, J. D. (2018).

3 min read NASA’s New Horizons to Continue Exploring Outer Solar System NASA has announced an updated plan to continue New Horizons’ mission of exploration of the outer solar system. Beginning in fiscal year 2025, New Horizons will focus on gathering unique heliophysics data, which can be readily obtained during an extended, low-activity mode of operations. While the science community is not currently aware of any reachable Kuiper Belt object, this new path allows for the possibility of using the spacecraft for a future close flyby of such an object, should one be identified. It also will enable the spacecraft to preserve fuel and reduce operational complexity while a search is conducted for a compelling flyby candidate. “The New Horizons mission has a unique position in our solar system to answer important questions about our heliosphere and provide extraordinary opportunities for multidisciplinary science for NASA and the scientific community,” said Nicola Fox, associate administrator for NASA’s Science Mission Directorate in Washington. “The agency decided that it was best to extend operations for New Horizons until the spacecraft exits the Kuiper Belt, which is expected in 2028 through 2029.” This new, extended mission will be primarily funded by NASA’s Planetary Science Division and jointly managed by NASA’s Heliophysics and Planetary Science Divisions. NASA will assess the budget impact of continuing the New Horizons mission so far beyond its original plan of exploration. As a starting point, funding within the New Frontiers program (including science research and data analysis) will be rebalanced to accommodate extended New Horizons operations, and future projects may be impacted. Launched on January 18, 2006, NASA’s New Horizons spacecraft has helped scientists understand worlds at the edge of our solar system by visiting the dwarf planet Pluto (its primary mission) and then venturing farther out for a flyby of the Kuiper belt object Arrokoth, a double-lobed relic of the formation of our solar system, and other more remote observations of similar bodies. The Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, designed, built and operates the New Horizons spacecraft, and manages the mission for NASA’s Science Mission Directorate. The Marshall Space Flight Center Planetary Management Office provides the NASA oversight for the New Horizons. Southwest Research Institute, based in San Antonio, directs the mission via Principal Investigator Stern, and leads the science team, payload operations and encounter science planning. New Horizons is part of the New Frontiers Program managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama.

3 min read Two NASA Goddard Earth Scientists Receive AGU Awards The American Geophysical Union (AGU) announced this month that two Earth scientists at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, were receiving medals from the organization. Dr. Dalia Kirschbaum was awarded a Joanne Simpson Medal for Mid-Career Scientists, and Dr. John Bolten received the AGU International Award. Kirschbaum is director of Goddard’s Earth Sciences Division, and Bolten leads the center’s Hydrological Sciences Lab. Dr. Dalia Kirschbaum, director of the Earth Science Division at NASA’s Goddard Space Flight Center in Greenbelt, Md., is one of three recipients of the American Geophysical Union’s 2023 Simpson Medal. Credit: NASANASA’s Goddard Space Flight Center “To receive an award named after such a prolific and impactful woman is a true honor,” Kirschbaum said. Dr. Joanne Simpson was the first woman to receive a doctorate in meteorology. As a tribute to her, AGU awards the medal to individuals with exceptional leadership qualities and an unwavering passion for scientific advancement for public service. Like Simpson’s groundbreaking research on tropical clouds and hurricanes, this award highlights mid-career scientists who have also made significant scientific breakthroughs. Kirschbaum is one of three recipients of AGU’s Simpson medal this year. “When I was an intern and Ph.D. researcher, I was fortunate enough to work at NASA and actually sit in Joanne Simpson’s office,” Kirschbaum said. “She had since retired but I was surrounded by her awards, her publications, and her contributions to NASA. She was one of the key scientific leaders to campaign for the Tropical Rainfall Measuring Mission (TRMM) and after the Global Precipitation Measurement (GPM) mission, which is still flying today. I have worked on TRMM and then GPM for my entire scientific career, which was all enabled by her tenacity, creativity, intelligence, and insight.” The award highlights the achievements of a broad Earth science team working to benefit humanity, Kirschbaum said. TRMM and GPM data, for example, has helped communities around the globe estimate where rainfall-triggered landslides may occur. Bolten’s award likewise commemorates work with a global impact. AGU selected Bolten for their International Award “for dedication to improving lives in Southeast Asia and Africa through development and training in the use of hydrological datasets and tools,” according to their citation. Dr. John Bolten, who leads NASA Goddard’s Hydrological Sciences Lab, received AGU’s 2023 International Award.NASA’s Goddard Space Flight Center Bolten has developed several research products to aid in water resources management around the world. Much of the work has been supported by NASA’s Applied Science Program, which enables the agency’s data products to deliver societal benefits. Bolten served as the associate program manager for water resources in the program from 2014 to 2022. “It is an incredible honor to serve the international community and to be recognized in this way,” Bolten said. “Thanks and kudos should be shared with the numerous NASA colleagues and collaborators I’ve had the privilege to work with. I am grateful for their contributions and am thrilled to be a part of the NASA family and make a positive impact in the world.” Kirschbaum echoed the globally minded mentality: Among her priorities as director of Goddard’s Earth Sciences Division is to “bring together the best of what NASA provides for societal benefit,” she said. “Our team will continue to innovate and improve these capabilities to support the agency, the nation, and the world.” Kirschbaum, who also received fellowship in AGU as part of her award, and Bolten will be recognized during the organization’s annual meeting in December.

NASA astronaut Jasmin Moghbeli works on microbe samples aboard the International Space Station. Studies newly funded by NASA’s Human Research Program aim to assess how astronauts adjust to spaceflight. Credit: NASA NASA is funding eight new studies aimed at better understanding how the human body reacts to spaceflight. These studies will be done on Earth without the need for samples and data from astronauts. Collectively, these studies will help measure physiological and psychological responses to physical and mental challenges that astronauts may encounter during spaceflight. With this information, NASA may be better able to mitigate risks and protect astronaut health and performance during future long-duration missions to the International Space Station, the Moon, Mars, and beyond. The selected research projects were chosen from 60 proposals submitted in response to the 2023 Human Exploration Research Opportunities, Appendix A solicitation. They will address numerous spaceflight risks related to muscle and bone health, sex differences, crew autonomy and behavior, balance and disorientation, and inflammation of the brain or spinal cord. Proposals were independently reviewed by subject matter experts in academia, industry, and government using a dual anonymous peer review process to assess scientific merit. Top scoring proposals were assessed by NASA for relevance to the agency’s Human Research Roadmap before final selections were made. The cumulative award totals about $1.2 million in funding, spread across the projects. Funding for each project will last up to one year. The selected investigators and their teams are: Heather Allaway, Louisiana State University and A&M College, “A time course of bone microarchitectural and material property changes in male and female mice during simulated unloading and spaceflight.” Kelly Crowe, Xavier University, “Assessment of Sialylation in Skeletal Muscle Atrophy due to Simulated Microgravity.” Anthony Lau, College of New Jersey, “Effects of Acute and Protracted Proton Radiation Exposure on Bone Health.” Ranjana Mehta, Texas A&M Engineering Experiment Station, “Characterizing and mitigating the interactive impacts of fatigue- and altered gravity-related stressors on sensorimotor, behavioral, and operational outcomes.” Kathleen Mosier, Teamscape LLC, “Negotiating Crew Autonomy during Space Operations.” Talmo Pereira, Salk Institute for Biological Studies, “Automated deep learning for spaceflight rodent behavior quantification and health phenotyping.” Shubhankar Suman, Georgetown University, “Senescent cell targeting to alleviate space radiation-induced neuroinflammation.” Danyal Turkoglu, Ultra Safe Nuclear Corporation – Space, “Radioisotope to Enable X-Ray Based Inflight Space Radiology.” ______ NASA’s Human Research Program, or HRP, pursues the best methods and technologies to support safe, productive human space travel.

Crew members aboard the International Space Station conducted a variety of scientific investigations during the week ending Sept. 29, 2023, including FLARE. This JAXA (Japan Aerospace Exploration Agency) investigation explores the flammability of materials in microgravity. Current tests of materials that are used in crewed spacecraft do not consider gravity, which significantly affects combustion phenomena. The ability for flames to spread over solid materials, for example, is affected by the forces of buoyancy, which are absent in microgravity. Removing the effects of buoyancy by conducting combustion experiments in microgravity also gives researchers a better understanding of specific flame behaviors. JAXA astronaut Satoshi Furukawa sets up hardware for the FLARE investigation. NASA Other investigations on the space station have examined the behavior, spread, and growth of fire. This work helps guide selection of spacecraft cabin materials, improve understanding of early fire growth behavior, validate models used to determine material flammability, and identify optimal fire suppression techniques. Developing ways to prevent and extinguish fire is of critical importance to the safety of crew members and vehicles in space and in confined spaces such as aircraft on Earth. These settings limit the options for suppressing fires and can be difficult to evacuate from. Burning and Suppression of Solids (BASS) was one of the first investigations to examine how to extinguish a variety of fuels burning in microgravity. Putting out fires in space must consider the geometry of the flame and characteristics of the materials and methods used to extinguish it, as those used on the ground could be ineffective or even make the flame worse. Analysis of 59 BASS burn tests provided data on heat flow, flame size, effects of fuel mixture flow, and other important parameters. BASS-II examined the burning and extinction characteristics of a variety of fuel samples to test the hypothesis that materials burn as well if not better in microgravity than in normal gravity, given adequate ventilation and identical conditions such as pressure, oxygen concentration, and temperature. A number of papers have been published based on results from BASS-II, with findings including a report on the differences between flame spread and fuel regression and comparison of flame spread rates. Image of a flame burning during the BASS experiments on extinguishing burning fuels. NASA Solid Fuel Ignition and Extinction – Growth and Extinction Limit (SoFIE-GEL), a research collaboration between NASA and Roscosmos, analyzes how the temperature of a fuel affects material flammability. Researchers report that experimental observations agree with trends predicted by the models. This investigation is the first in a series using the SoFIE insert for the station’s Combustion Integrated Rack. ESA (European Space Agency) astronaut Samantha Cristoforetti works on the SoFIE-GEL investigation of materials flammability.NASA Saffire is a series of experiments conducted aboard uncrewed Cygnus cargo spacecraft after they depart the station. Using these cargo vehicles provides distance from the crewed station and enables tests of larger fires. Results have shown that a flame spreading over thin fabrics in microgravity reaches a steady spread rate and a limiting length, which can be used to establish the rate of heat release in a spacecraft, and found that reducing pressure slows down the flame spread. A sample of fabric burns inside an uncrewed Cygnus cargo craft for the Saffire-IV experiment. NASA Confined Combustion, sponsored by the ISS National Lab, examines the behavior of flame spread in confined spaces of different shapes. Confinement has been shown to have significant effects on fire characteristics and hazards. Researchers report specifics on interactions between a flame and its surrounding walls and the fate of the flame, such as growth or extinction. These data provide guidance for design of structures and fire safety codes and response in space and on Earth. Other results suggest that confinement can increase or decrease solid fuel flammability depending on conditions. Researchers also demonstrated that color pyrometry – capturing flame emission simultaneously at three broad spectral bands – can determine the temperature of a flame without disrupting its spread. Flame studies help keep crews in space and people on Earth safe. This research also can lead to more efficient combustion, reducing impurities and producing greener and more efficient flames for uses on Earth such as heating and transportation.

5 min read Life Encapsulated: Inside NASA’s Orion for Artemis II Moon Mission Artemis II crew members, shown inside the Neil Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida, stand in front of their Orion crew module on Aug. 8, 2023. From left are: Jeremy Hansen, mission specialist; Victor Glover, pilot; Reid Wiseman, commander; and Christina Hammock Koch, mission specialist. On NASA’s upcoming Artemis II mission, four astronauts will fly inside the Orion spacecraft and venture around the Moon, becoming the first to lay their eyes on our celestial neighbor at a relatively close distance in more than 50 years. Orion will be home for NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and Canadian Space Agency (CSA) astronaut Jeremy Hansen during their 600,000-mile, nearly 10-day journey. They will live and work in Orion’s crew module while its service module provides the essential commodities astronauts need to stay alive, including potable water and nitrogen and oxygen to breathe. As the first time astronauts will fly aboard Orion, Artemis II will include several objectives to check out many of the spacecraft’s life support systems operating in space for the first time. The crew will provide valuable feedback for future Artemis missions to the Moon. Artemis II crew members inspect their Orion crew module inside the high bay of the Neil A. Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida, on Aug. 7, 2023. Spacecraft Life Orion’s cabin has a habitable volume of 330 cubic feet, giving the crew about as much living space as two minivans. After their ride to space atop NASA’s SLS (Space Launch System) rocket, the crew will stow Koch and Hansen’s seats until the day of return, giving them more room to move around during the flight. The backs of Wiseman and Glover’s seats, as commander and pilot respectively, will remain out but their foot pans will be stowed. Orion has nearly 60 percent more space than the Apollo command module’s 210 cubic feet. A view of the interior of the Orion spacecraft medium-fidelity mockup used for astronaut training and systems familiarization at NASA’s Johnson Space Center in Houston. What’s on the Menu? Food scientists in the Space Food Systems Laboratory at the agency’s Johnson Space Center in Houston are working with the crew to pre-select their meals long before departing Earth. While they won’t have the day-to-day options that a space station crew has during their expeditions, the Artemis II astronauts will have a set menu based on their personal preferences and nutritional needs. Orion is outfitted with a water dispenser and food warmer to rehydrate and heat food, and the crew will have dedicated meal times in their schedule to refuel. Artemis II crew members undergo food testing in the Space Food Systems Laboratory at NASA’s Johnson Space Center, where they rate and choose foods that they want to bring with them on their journey around the Moon.NASA/James Blair Fit for Flight Each astronaut will dedicate 30 minutes daily to exercise, minimizing the muscle and bone loss that occurs without gravity. Orion is equipped with a flywheel, a small device installed directly below the side hatch used to enter and exit Orion and will conveniently be used as a step when the crew get inside Orion on launch day. The flywheel is a simple cable-based device for aerobic exercises like rowing and resistance workouts like squats and deadlifts. It works like a yo-yo, giving astronauts as much load as they put into it, maxing out at 400 pounds. On the International Space Station, astronauts have several exercise machines that collectively weigh more than 4,000 pounds and occupy about 850 cubic feet. While effective for space station crew members, Orion’s exercise equipment must accommodate more stringent mass and volume constraints. The flywheel weighs approximately 30 pounds and is slightly smaller than a carry-on suitcase. The Artemis II crew will exercise on Orion using a flywheel, a simple cable-based device for aerobic exercises like rowing and resistance workouts like squats and deadlifts. It works like a yo-yo, giving astronauts as much load as they put into it, maxing out at 400 pounds. Keeping it Clean The hygiene bay includes doors for privacy, a toilet, and space for the crew to bring in their personal hygiene kits. The kits typically include items like a hairbrush, toothbrush and toothpaste, soap, and shaving supplies. Astronauts can’t shower in space but use liquid soap, water, and rinseless shampoo to remain clean. When nature inevitably comes calling, crew members will use Orion’s toilet, the Universal Waste Management System, a feature Apollo crews did not have. Nearly identical to a version flying on NASA’s space station, the system collects urine and feces separately. Urine will be vented overboard while feces are collected in a can and safely stowed for disposal upon return. Should the toilet malfunction, the crew will be able to use collapsible contingency urinals, a system that collects urine in a bag and interfaces with the venting system to send the urine overboard. With two different styles designed to accommodate both females and males, the bags hold about a liter of urine each. Should the UWMS fail, the crew will still use the toilet for fecal collection, only without the fan that helps with fecal separation. A team member at Johnson Space Center in Houston demonstrates lifting the urine hose of the Universal Waste Management System out of its cradled position like a crew member would for use. A funnel (not shown) is attached to the open end of this hose and can then be easily replaced or removed for disinfection. Medical Care In case of minor medical needs during the mission, Orion will have a medical kit on board that includes everything from basic first aid items to diagnostic tools, such as a stethoscope and an electrocardiogram, that can be used to provide data to physicians on the ground. The crew will also have regular private medical conferences with flight surgeons in mission control to discuss their health and well-being. Catching Some Shuteye With a jam-packed schedule, the Artemis II crew will have a full eight hours of sleep built into their schedule to ensure they’re well rested and can make the most of their mission. For most of the mission, all four crew will sleep at the same time, attaching sleeping bags to Orion’s walls for some shuteye. Artemis II crew sleeping bag configurations are tested in the Orion spacecraft medium-fidelity mockup at NASA’s Johnson Space Center in Houston, used for astronaut training and systems familiarization. Keeping in Touch Inside Orion, the astronauts will use a handheld microphone and speaker or wear a headset to communicate with mission controllers, conduct medical checks with flight physicians, and catch up with their families. The crew will also have tablets and laptops they can use to review procedures and load entertainment onto before launch. Artemis II will confirm all Orion’s systems operate as designed with crew aboard in the actual environment of deep space. The mission will pave the way for future lunar surface missions, including by the first woman and first person of color, establishing long-term lunar science and exploration capabilities, and inspire the next generation of explorers – The Artemis Generation.
