      Crew members are kicking off operations for several biological experiments that recently launched to the International Space Station aboard NASA’s 32nd SpaceX commercial resupply services mission. These include examining how microgravity affects production of protein by microalgae, testing a microscope to capture microbial activity, and studying genetic activity in biofilms.
      Microalgae in microgravity
      Sophie’s BioNutrients This ice cream is one of several products made with a protein powder created from Chorella microalgae by researchers for the SOPHONSTER investigation, which looks at whether the stress of microgravity affects the algae’s protein yield. Microalgae are nutrient dense and produce proteins with essential amino acids, beneficial fatty acids, B vitamins, iron, and fiber. These organisms also can be used to make fuel, cooking oil, medications, and materials. Learning more about microalgae growth and protein production in space could support development of sustainable alternatives to meat and dairy. Such alternatives could provide a food source on future space voyages and for people on Earth and be used to make biofuels and bioactive compounds in medicines.
      Microscopic motion
      Portland State University These swimming microalgae are visible thanks to the Extant Life Volumetric Imaging System or ELVIS, a fluorescent 3D imaging microscope that researchers are testing aboard the International Space Station. The investigation studies both active behaviors and genetic changes of microscopic algae and marine bacteria in response to spaceflight. ELVIS is designed to autonomously capture microscopic motion in 3D, a capability not currently available on the station. The technology could be useful for a variety of research in space and on Earth, such as monitoring water quality and detecting potentially infectious organisms.
      Genetics of biofilms
      BioServe This preflight image shows sample chambers for the Genetic Exchange in Microgravity for Biofilm Bioremediation (GEM-B2) investigation, which examines the mechanisms of gene transfer within biofilms under microgravity conditions. Biofilms are communities of microorganisms that collect and bind to a surface. They can clog and foul water systems, often leave a residue that can cause infections, and may become resistant to antibiotics. Researchers could use results from this work to develop genetic manipulations that inhibit biofilm formation, helping to maintain crew health and safety aboard the International Space Station and on future missions.

New SCALPSS hardware delivered for Blue Origin’s Blue Mark 1 mission also is enhancing lunar landing models, helping build precision landing systems for the Moon and Mars. The LuGRE (Lunar Global Navigation Satellite System Receiver Experiment) on Blue Ghost acquired Earth navigation signals from the Moon, advancing autonomous positioning systems crucial for lunar and Mars operations. The Electrodynamic Dust Shield successfully cleared lunar dust, demonstrating a critical technology for protecting equipment on the Moon and Mars. Astronauts aboard the space station conducted studies to advance understanding of how to keep crews healthy on long-duration Mars missions. NASA’s Moon to Mars Architecture Workshop gathered industry, academic, and international partners to refine exploration plans and identify collaboration opportunities. Artemis Milestones
      NASA completed stacking the twin solid rocket boosters for Artemis II, the mission that will send American astronauts around the Moon for the first time in more than 50 years. This is a powerful step toward returning our nation to deep space. At NASA’s Kennedy Space Center in Florida, teams joined the core stage with the solid rocket boosters inside the Vehicle Assembly Building. Engineers lifted the launch vehicle stage adapter atop the SLS (Space Launch System) core stage, connecting key systems that will soon power NASA’s return to the Moon. Teams received the Interim Cryogenic Propulsion Stage and moved the SLS core stage into the transfer aisle, clearing another milestone as the agency prepares to fully integrate America’s most powerful rocket. NASA attached the solar array wings that will help power the Orion spacecraft on its journey around the Moon, laying the groundwork for humanity’s next giant leap. Technicians installed the protective fairings on Orion’s service module to shield the spacecraft during its intense launch and ascent phase, as NASA prepares to send astronauts farther than any have gone in more than half a century. The agency’s next-generation mobile launcher continues to take shape, with the sixth of 10 massive modules being installed. This structure will carry future Artemis rockets to the launch pad. NASA and the Department of Defense teamed up aboard the USS Somerset for Artemis II recovery training, ensuring the agency and its partners are ready to safely retrieve Artemis astronauts after their historic mission around the Moon. NASA unveiled the Artemis II mission patch. The patch designates the mission as “AII,” signifying not only the second major flight of the Artemis campaign but also an endeavor of discovery that seeks to explore for all and by all. America First in Space
      NASA announced the first major science results from asteroid Bennu, revealing ingredients essential for life, a discovery made possible by U.S. leadership in planetary science through the OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) mission. The team found salty brines, 14 of the 20 amino acids used to make proteins, and all five DNA nucleobases, suggesting that the conditions and ingredients for life were widespread in our early solar system. And this is just the beginning – these results were from analysis of only 0.06% of the sample. NASA was named one of TIME’s Best Companies for Future Leaders, underscoring the agency’s role in cultivating the next generation of American innovators. NASA awarded contracts to U.S. industry supporting Earth science missions,  furthering our understanding of the planet while strengthening America’s industrial base. As part of the Air Traffic Management-Exploration project, NASA supported Boeing’s test of digital and autonomous taxiing with a Cessna Caravan at Moffett Federal Airfield. The test used real-time simulations from the agency’s Future Flight Central to gather data that will help Boeing refine its systems and safely integrate advanced technologies into national airspace, demonstrating American aviation leadership. NASA successfully completed its automated space traffic coordination objectives between the agency’s four Starling spacecraft and SpaceX’s Starlink constellation. Teams demonstrated four risk mitigation maneuvers, autonomously resolving close approaches between two spacecraft with different owner/operators.   In collaboration with the National Institute of Aeronautics, NASA selected eight finalists in a university competition aimed at designing innovative aviation solutions that can help the agriculture industry. NASA’s Gateways to Blue Skies seeks ways to apply American aircraft and aviation technology to enhance the productivity, efficiency, and resiliency of American farms.  In Houston, United Airlines pilots successfully conducted operational tests of NASA-developed technologies designed to reduce flight delays. Using technologies from the Air Traffic Management Exploration project, pilots flew efficient re-routes, avoiding airspace with bad weather upon departure. United plans to expand the use of these capabilities, another example of how NASA innovations benefit all humanity.  On March 11, NASA’s newest astrophysics observatory, SPHEREx, launched on its journey to answer fundamental questions about our universe, thanks to the dedication and expertise of the agency’s team. Riding aboard a SpaceX Falcon 9 from Vandenberg Space Force Base, SPHEREx will scan the entire sky to study how galaxies formed, search for the building blocks of life, and look back to the universe’s earliest moments. After launch, SPHEREx turned on its detectors, and everything is performing as expected. Also onboard were four small satellites for NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission, which will help scientists understand how the Sun’s outer atmosphere becomes solar wind. These missions reflect the best of the agency – pushing the boundaries of discovery and expanding our understanding of the cosmos. On March 14, NASA’s EZIE (Electrojet Zeeman Imaging Explorer) mission launched from Vandenberg Space Force Base. This trio of small satellites will study auroral electrojets, or intense electric currents flowing high above Earth’s poles, helping the agency better understand space weather and its effects on our planet. The mission has taken its first measurements, demonstrating that the spacecraft and onboard instrument are working as expected. The X-59 quiet supersonic aircraft cleared another hurdle on its way to first flight. The team successfully completed an engine speed hold test, confirming the “cruise control” system functions as designed.  NASA researchers successfully tested a prototype that could help responders fight and monitor wildfires, even in low-visibility conditions. The Portable Airspace Management System, developed by NASA’s Advanced Capabilities for Emergency Response Operations project, safely coordinated simulated operations involving drones and other aircraft, tackling a major challenge for those on the front lines. This is just one example of how NASA’s innovation is making a difference where it’s needed most.  NASA’s Parker Solar Probe completed its 23rd close approach to the Sun, coming within 3.8 million miles of the solar surface while traveling at 430,000 miles per hour – matching its own records for distance and speed. That same day, Parker Solar Probe was awarded the prestigious Collier Trophy, a well-earned recognition for its groundbreaking contributions to heliophysics.  In response to severe weather that impacted more than 10 states earlier this month, the NASA Disasters Response Coordination System activated to support national partners. NASA worked closely with the National Weather Service and the Federal Emergency Management Agency serving the central and southeastern U.S. to provide satellite data and expertise that help communities better prepare, respond, and recover.  As an example of how NASA’s research today is shaping the transportation of tomorrow, the agency’s aeronautics engineers began a flight test campaign focused on safely integrating air taxis into the national airspace. Using a Joby Aviation demonstrator aircraft, engineers are helping standardize flight test maneuvers, improving tools to assist with collision avoidance and landing operations, and ensuring safe and efficient air taxis operations in various weather conditions. NASA premiered “Planetary Defenders,” a new documentary that follows the dedicated team behind asteroid detection and planetary defense. The film debuted at an event at the agency’s headquarters with digital creators, interagency and international partners, and now is streaming on NASA+, YouTube, and X. In its first 24 hours, it saw 25,000 views on YouTube – 75% above average – and reached 4 million impressions on X.  Finland became the 53rd nation to sign the Artemis Accords, reaffirming its commitment to the peaceful, transparent, and responsible exploration of space. This milestone underscores the growing global coalition led by the United States to establish a sustainable and cooperative presence beyond Earth. In Dhaka, Bangladesh, NASA welcomed a new signatory to the Artemis Accords. Bangladesh became the 54th nation to commit to the peaceful, safe, and responsible exploration of space. It’s a milestone that reflects our shared values and growing global momentum, reaffirming the United States’ leadership in building a global coalition for peaceful space exploration.  At NASA’s Armstrong Flight Research Center in Edwards, California, engineers conducted calibration flights for a new shock-sensing probe that will support future flight tests of the X-59 quiet supersonic demonstrator. Mounted on a research F-15D that will follow the X-59 closely in flight, the probe will gather data on the shock waves the X-59 generates, providing important data about its ability to fly faster than sound, but produce only a quiet thump. In its second asteroid encounter, Lucy flew by the asteroid Donaldjohanson and gave NASA a close look at a uniquely shaped fragment dating back 150 million years – an impressive performance ahead of its main mission target in 2027. A celebration of decades of discovery, NASA’s Hubble Space Telescope celebrated its 35th anniversary with new observations ranging from nearby solar system objects to distant galaxies – proof that Hubble continues to inspire wonder and advance our understanding of the universe. The SPHEREx team rang the closing bell at the New York Stock Exchange, spotlighting NASA’s newest space telescope and its bold mission to explore the origins of the universe. NASA received six Webby Awards and six People’s Voice Awards across platforms – recognition of America’s excellence in digital engagement and public communication. The NASA Electric Aircraft Testbed and Advanced Air Transport Technology project concluded testing of a 2.5-megawatt Wright Electric motor designed to eventually serve large aircraft. The testing used the project’s capabilities to simulate altitude conditions of up to 40,000 feet while the electric motor, the most powerful tested so far at the facility, ran at both full voltage and partial power. NASA partnered with the Department of Energy on the tests. U.S. entities can now request the Glenn Icing Computational Environment (GlennICE) tool from the NASA Software Catalog and discover solutions to icing challenges for novel engine and aircraft designs. A 3D computational tool, GlennICE allows engineers to integrate icing-related considerations earlier in the aircraft design process and enable safer, more efficient designs while saving costs in the design process.

      Help Classify Galaxies Seen by NASA’s James Webb Space Telescope!
      The Galaxy Zoo classification interface shows you an image from NASA’s Webb telescope and asks you questions about it. Image credit: Galaxy Zoo, Zooniverse. Inset galaxy: NASA/STScI/CEERS/TACC/S. Finkelstein/M. Bagley/Z. Levay/A. Pagan NASA needs your help identifying the shapes of thousands of galaxies in images taken by our James Webb Space Telescope with the Galaxy Zoo project. These classifications will help scientists answer questions about how the shapes of galaxies have changed over time, what caused these changes, and why. Thanks to the light collecting power of Webb, there are now over 500,000 images of galaxies on website of the Galaxy Zoo citizen science project—more images than scientists can classify by themselves. 
      “This is a great opportunity to see images from the newest space telescope,” said volunteer Christine Macmillan from Aberdeen, Scotland. “Galaxies at the edge of our universe are being seen for the first time, just as they are starting to form. Just sign up and answer simple questions about the shape of the galaxy that you are seeing. Anyone can do it, ages 10 and up!”  
      As we look at more distant objects in the universe, we see them as they were billions of years ago because light takes time to travel to us. With Webb, we can spot galaxies at greater distances than ever before. We’re seeing what some of the earliest galaxies ever detected look like, for the first time. The shapes of these galaxies tell us about how they were born, how and when they formed stars, and how they interacted with their neighbors. By looking at how more distant galaxies have different shapes than close galaxies, we can work out which processes were more common at different times in the universe’s history.   
      At Galaxy Zoo, you’ll first examine an image from the Webb telescope. Then you will be asked several questions, such as ‘Is the galaxy round?’, or ‘Are there signs of spiral arms?’. If you’re quick, you may even be the first person to see the galaxies you’re asked to classify.  
      “I’m amazed and honored to be one of the first people to actually see these images! What a privilege!” said volunteer Elisabeth Baeten from Leuven, Belgium.
      Galaxy Zoo is a citizen science project with a long history of scientific impact. Galaxy Zoo volunteers have been exploring deep space since July 2007, starting with a million galaxies from a telescope in New Mexico called the Sloan Digital Sky Survey and then, moving on to images from space telescopes like NASA’s Hubble Space Telescope and ESA (European Space Agency)’s Euclid telescope. The project has revealed spectacular mergers, taught us about how the black holes at the center of galaxies affect their hosts, and provided insight into how features like spiral arms form and grow.  
      Now, in addition to adding new data from Webb, the science team has incorporated an AI algorithm called ZooBot, which will sift through the images first and label the ‘easier ones’ where there are many examples that already exist in previous images from the Hubble Space Telescope. When ZooBot is not confident on the classification of a galaxy, perhaps due to complex or faint structures, it will show it to users on Galaxy Zoo to get their human classifications, which will then help ZooBot learn more. Working together, humans and AI can accurately classify limitless numbers of galaxies. The Galaxy Zoo science team acknowledges support from the International Space Sciences Institute (ISSI), who provided funding for the team to get together and work on Galaxy Zoo. Join the project now.

      5 Min Read NASA 3D Wind Measuring Laser Aims to Improve Forecasts from Air, Space
      3D wind measurements from NASA's Aerosol Wind Profiler instrument flying on board a specially mounted aircraft along the East Coast of the U.S. and across the Great Lakes region on Oct. 15, 2024. Credits: NASA/Scientific Visualization Studio Since last fall, NASA scientists have flown an advanced 3D Doppler wind lidar instrument across the United States to collect nearly 100 hours of data — including a flight through a hurricane. The goal? To demonstrate the unique capability of the Aerosol Wind Profiler (AWP) instrument to gather extremely precise measurements of wind direction, wind speed, and aerosol concentration – all crucial elements for accurate weather forecasting.
      Weather phenomena like severe thunderstorms and hurricanes develop rapidly, so improving predictions requires more accurate wind observations.
      “There is a lack of global wind measurements above Earth’s surface,” explained Kris Bedka, the AWP principal investigator at NASA’s Langley Research Center in Hampton, Virginia. “Winds are measured by commercial aircraft as they fly to their destinations and by weather balloons launched up to twice per day from just 1,300 sites across the globe. From space, winds are estimated by tracking cloud and water vapor movement from satellite images.”
      However, in areas without clouds or where water vapor patterns cannot be easily tracked, there are typically no reliable wind measurements. The AWP instrument seeks to fill these gaps with detailed 3D wind profiles.
      The AWP instrument (foreground) and HALO instrument (background) was integrated onto the floorboard of NASA’s G-III aircraft. Kris Bedka, project principal investigator, sitting in the rear of the plane, monitored the data during a flight on Sept. 26, 2024. NASA/Maurice Cross Mounted to an aircraft with viewing ports underneath it, AWP emits 200 laser energy pulses per second that scatter and reflect off aerosol particles — such as pollution, dust, smoke, sea salt, and clouds — in the air. Aerosol and cloud particle movement causes the laser pulse wavelength to change, a concept known as the Doppler effect.
      The AWP instrument sends these pulses in two directions, oriented 90 degrees apart from each other. Combined, they create a 3D profile of wind vectors, representing both wind speed and direction.
      We are measuring winds at different altitudes in the atmosphere simultaneously with extremely high detail and accuracy.
      Kris bedka
      NASA Research Physical Scientist
      “The Aerosol Wind Profiler is able to measure wind speed and direction, but not just at one given point,” Bedka said. “Instead, we are measuring winds at different altitudes in the atmosphere simultaneously with extremely high detail and accuracy.”
      Vectors help researchers and meteorologists understand the weather, so AWP’s measurements could significantly advance weather modeling and forecasting. For this reason, the instrument was chosen to be part of the National Oceanic and Atmospheric Administration’s (NOAA) Joint Venture Program, which seeks data from new technologies that can fill gaps in current weather forecasting systems. NASA’s Weather Program also saw mutual benefit in NOAA’s investments and provided additional support to increase the return on investment for both agencies.
      On board NASA’s Gulfstream III (G-III) aircraft, AWP was paired with the agency’s High-Altitude Lidar Observatory (HALO) that measures water vapor, aerosols, and cloud properties through a combined differential absorption and high spectral resolution lidar.
      Working together for the first time, AWP measured winds, HALO collected water vapor and aerosol data, and NOAA dropsondes (small instruments dropped from a tube in the bottom of the aircraft) gathered temperature, water vapor, and wind data.
      The AWP and HALO instrument teams observing incoming data on board NASA’s G-III aircraft over Tennessee while heading south to observe Hurricane Helene. Sept. 26, 2024. NASA/Maurice Cross “With our instrument package on board small, affordable-to-operate aircraft, we have a very powerful capability,” said Bedka. “The combination of AWP and HALO is NASA’s next-generation airborne weather remote sensing package, which we hope to also fly aboard satellites to benefit everyone across the globe.”

      The animation below, based on AWP data, shows the complexity and structure of aerosol layers present in the atmosphere. Current prediction models do not accurately simulate how aerosols are organized throughout the breadth of the atmosphere, said Bedka.

      This visualization shows AWP 3D measurements gathered on Oct. 15, 2024, as NASA’s G-III aircraft flew along the East Coast of the U.S. and across the Great Lakes region. Laser light that returns to AWP as backscatter from aerosol particles and clouds allows for measurement of wind direction, speed, and aerosol concentration as seen in the separation of data layers. NASA/Scientific Visualization Studio “When we took off on this particular day, I thought that we would be finding a clear atmosphere with little to no aerosol return because we were flying into what was the first real blast of cool Canadian air of the fall,” described Bedka. “What we found was quite the opposite: an aerosol-rich environment which provided excellent signal to accurately measure winds.” 
      During the Joint Venture flights, Hurricane Helene was making landfall in Florida. The AWP crew of two pilots and five science team members quickly created a flight plan to gather wind measurements along the outer bands of the severe storm.

      This video shows monitors tracking the AWP science team’s location in the western outer bands of Hurricane Helene off the coast of Florida with views outside of the aircraft looking at turbulent storm clouds on Sept. 26, 2024. NASA/Kris Bedka “A 3D wind profile can significantly improve weather forecasts, particularly for storms and hurricanes,” said Harshesh Patel, NOAA’s acting Joint Venture Program manager. “NASA Langley specializes in the development of coherent Doppler wind lidar technology and this AWP concept has potential to provide better performance for NOAA’s needs.”

NASA/John Cooney The flights of the AWP lidar are serving as a proving ground for possible integration into a future satellite mission.
      “The need to improve global 3D wind models requires a space-based platform,” added Patel. “Instruments like AWP have specific space-based applications that potentially align with NOAA’s mission to provide critical data for improving weather forecasting.”
