Advancing Technology for Aeronautics on Earth

The future of flight looks very exciting, and the public is helping NASA see it more clearly. For more than a century, NASA and its predecessor, the National Advisory Committee for Aeronautics, have been the global leader in aeronautics research. NASA’s innovative contributions to aviation benefit the U.S. economy, air transportation system, aviation industry, and passengers and businesses who rely on flight every day. NASA is with you when you fly, and the agency continues to revolutionize research and development activities for the aviation industry of tomorrow.  

NASA’s public prize competitions, challenges, and crowdsourcing activities illuminate what is on the horizon for air and aviation on Earth. These research and development challenges yield innovative ideas, including future forecasts to inform strategies for the next era of aviation, algorithms to predict runway traffic changes at U.S. airports, and more. 

Future Forecasts to Prepare for the Next Era of Aeronautics

NASA’s vision for aeronautical research for the next 25 years and beyond encompasses a range of technologies for safe, efficient, flexible, and environmentally sustainable air transportation. To prepare for this future, NASA’s Convergent Aeronautics Solutions project conducted a challenge that prompted the public to imagine the state of aviation in 25 years. 

NASA’s Future-Scaping Our Skies Challenge asked participants to predict and describe future aviation using timelines and storylines, including data sources, references, and multimedia illustrations when possible. The contest awarded $21,000 to nine top winners. Judges evaluated the contest submissions based on their descriptions of possible future scenarios and the key events and trends leading to the proposed outcomes. 

According to Team Sparkletron, which placed first in the competition, advanced computation and machine learning might be modeling changes in aviation and the future of aviation better than ever. Such models could apply to commercial and personal flying applications.

Ground Control Software for Unmanned Aircraft Systems

In 2021, more than 873,000 Unmanned Aircraft Systems (UAS)—also known as drones—were registered to fly in the United States. With a host of potential applications, including delivery of products, search and rescue, and agricultural monitoring, drone numbers will likely rise.1

Working in partnership with the Federal Aviation Administration for more than 25 years, NASA is researching technologies for traffic management of drones. A large portion of air traffic management is ground control, which manages aircraft on the runways. To help develop ground control software for small drones, NASA asked the public to modify and enhance an existing application through an Unmanned Aircraft Systems Ground Control Station Software Challenge series. During the course of about a year, a series of challenges received 92 entries from 58 countries. Altogether, NASA awarded a total of $30,700 to 47 winners for the development of ground control software for small drones.

Algorithms to Predict Runway Traffic Changes at U.S. Airports

The National Airspace System (NAS) is undergoing modernization to make flying safer, more efficient, and more predictable2—and NASA is involved in this transformation. The NAS is made up of more than 29 million square miles that include airspace, air navigation facilities, airports and landing areas, and more.

To enable more cohesive decision-making in current and future NAS operations, NASA is building a cloud-based Digital Information Platform (DIP) for advanced data-driven digital services. Through DIP, NASA identified a need for algorithms that can accurately predict changes in the configuration of runways at U.S. airports. Runway configuration, or the direction that traffic is moving on runways, can adjust multiple times per day and can significantly impact flight delays and decisions across the NAS.3

The goal of the Run-way Functions: Predict Reconfigurations at U.S. Airports Challenge was to design algorithms to automatically predict airport configuration changes from real-time data sources. Submissions tested using a mock data set of 10 airports, and judges scored the algorithms based on how the predictions compared to the ground truth. The top four solutions, which came from New York University; Massachusetts Institute of Technology, Cambridge; University of Maryland, College Park; and Pennsylvania State University, State College, won awards totaling $40,000.

An App to Uncover How People Operate Autonomous Systems

Human-autonomy teaming (HAT) aims to understand how people work together with autonomous systems like drones. For example, how long can a person safely operate a drone piloted by remote control or onboard computers? Can one person effectively operate multiple autonomous vehicles at once? 

NASA opened the Human-Autonomy Teaming Task Battery (HATTB) App contest to develop software to run an existing battery of tasks that simulate pilot responsibilities during flight. The potential app could support researchers in evaluating the performance of research participants while participants monitored virtual autonomous machines and performed other tasks simultaneously. More than $160,000 was awarded to 33 contest winners. 

The HATTB app could help NASA and other researchers understand how well people and autonomous systems communicate and collaborate. The app is incorporated into a study by students at Old Dominion University in Norfolk, Virginia, to examine the effect of time on HAT.4

A More Efficient Wind Tunnel Design to Minimize Downtime

NASA facilities are home to a variety of wind tunnels for testing aircraft and spacecraft. By simulating the movement of air around vehicles during flight, NASA uses wind tunnels to test new vehicle shapes, materials, and other design elements.

The NASA concept study, “New Wind Tunnel Landscape,” aims to develop new options to support wind tunnel testing in the next 20-50 years. One opportunity for advancement is the test section—the area where researchers place the components, exposing them to airflow. When preparing the test section for a new model, the wind tunnel is unusable due to the time-consuming process.

To address the downtime, NASA called on the public through the New Transonic Wind Tunnel Test Section Challenge. This $7,000 competition sought new designs for a wind tunnel facility with test sections capable of efficient, rapid reconfiguration. 

Winning designs addressed the inefficiency of data and instrumentation system connections that delay reconfiguring the test section, ground-level carts to simplify transferring models to and from the test section, and modular test section containers that include everything needed for a quick swap.

      The Earth Observer Editor’s Corner: July–September 2025
      NOTE TO READERS: After more than three decades associated with or directly employed by NASA, Steve Platnick [GSFC—Deputy Director for Atmospheres, Earth Sciences Division] stepped down effective August 8, 2025. Steve began his civil servant career at GSFC in 2002, but his GSFC association went back to 1993, first as a contractor and then as one of the earliest employees of the Joint Center for Earth Systems Technology (JCET). During his time at NASA, Steve played an integral role in the sustainability and advancement of NASA’s Earth Observing System platforms and data. He was actively involved in the Moderate Resolution Imaging Spectroradiometer (MODIS) Science Team, where he helped advance several key components of the MODIS instrument. He was also the NASA Lead/co-Lead for the Suomi National Polar-orbiting Partnership (Suomi NPP), Atmosphere Discipline from 2012–2020 where he focused on operational cloud optical and microphysical products.
      In 2008, Steve became the Earth Observing System (EOS) Senior Project Scientist. In this role, he led the EOS Project Science Office that supported airborne sensors, ground networks, and calibration labs. The Kudos article titled “Steve Platnick Steps Down from NASA After 34 Years of Service” includes a more detailed account of Steve’s career and includes a list of awards he has received.
      Steve’s departure leaves a vacancy in the author’s chair for “The Editor’s Corner” – another role Steve filled as EOS Senior Project Scientist. Barry Lefer [NASA Headquarters—Associate Director of Research, Earth Science Division] graciously agreed to serve as guest author of the editorial in the current compilation. I want to thank Steve for all his support for The Earth Observer over the years and thank Barry for stepping in as the author of “The Editor’s Corner” for the time being.
      –Alan Ward, Executive Editor, The Earth Observer
      I begin this editorial with news of a successful Earth science launch. At 5:40 PM Indian Standard Time (IST), or 8:10 AM Eastern Daylight Time (EDT), on July 30, 2025, the joint NASA–Indian Space Research Organization (ISRO) Synthetic Aperture Radar, or NISAR, mission launched from the Satish Dhawan Space Centre on India’s southeastern coast aboard an ISRO Geosynchronous Satellite Launch Vehicle (GSLV) rocket 5. The ISRO ground controllers began communicating with NISAR about 20 minutes after launch, at just after 8:29 AM EDT, and confirmed it is operating as expected.
      NISAR will use two different radar frequencies (L-band SAR and S-band SAR) to penetrate clouds and forest canopies. Including L-band and S-band radars on one satellite is an evolution in SAR airborne and space-based missions that, for NASA, started in 1978 with the launch of Seasat. In 2012, ISRO began launching SAR missions starting with Radar Imaging Satellite (RISAT-1), followed by RISAT-1A in 2022, to support a wide range of applications in India.
      Combining the data from these two radars will allow researchers to systematically and globally map Earth – measuring changes of our planet’s surface down to a centimeter (~0.4 inches). With this detailed view, researchers will have an unprecedented ability to observe and measure complex processes from ecosystem disturbances to natural hazards to groundwater issues. All NISAR science data will be freely available and open to the public.
      Following the successful launch, NISAR entered an approximately 90-day commissioning phase to test out systems before science operations begin. A key milestone of that phase was the completion of the deployment of the 39-ft (12-m) radar antenna reflector on August 15 – see Video. The process began on August 9, when the satellite’s boom, which had been tucked close to its main body, started unfolding one joint at a time until it was fully extended about four days later. The reflector assembly is mounted at the end of the boom. On August 15, small explosive bolts that held the reflector assembly in place were fired, enabling the antenna to begin a process called the bloom – its unfurling by the release of tension stored in its flexible frame while stowed like an umbrella. Subsequent activation of motors and cables pulled the antenna into its final, locked position.
      Video: NISAR mission team members at NASA JPL, working with colleagues in India, executed the deployment of the satellite’s radar antenna reflector on Aug. 15, 2025. About 39 feet (12 meters) in diameter, the reflector directs microwave pulses from NISAR’s two radars toward Earth and receives the return signals. Credit: NASA/JPL-Caltech The radar reflector will be used to direct and receive microwave signals from the two radars. By interpreting the differences between the L-band and S-band measurements, researchers will be able to discern characteristics about the surface below. As NISAR passes over the same locations twice every 12 days, scientists can evaluate how those characteristics have changed over time to reveal new insights about Earth’s dynamic surfaces.
      With the radar reflector now in full bloom, scientists have turned their attention to tuning and testing the radar and preparing NISAR for Science Operations, which are anticipated to start around the beginning of November. Congratulations to the NISAR team on a successful launch and deployment of the radar reflector. Along with the science community, I am excited to see what new discoveries will result from the data collected by the first Earth System Observatory mission.
      Turning now to news from active missions, the Soil Moisture Active Passive (SMAP) mission has collected over 10 years of global L-band radiometry observations that have resulted in surface soil moisture, vegetation optical depth (VOD), and freeze/thaw state estimates that outperform past and current products. A decade of SMAP soil moisture observations has led to scientific achievements, including quantifying the linkages of the three main metabolic cycles (e.g., carbon, water, and energy) on land. The data have been widely used by the Earth system science community to improve drought assessments and flood prediction as well as the accuracy of numerical weather prediction models.
      SMAP’s Early Adopter program has helped connect SMAP data with people and organizations that need it. The program has increased the awareness of SMAP mission products, broadened the user community, increased collaboration with potential users, improved knowledge of SMAP data product capabilities, and expedited the distribution and uses of mission products for a suite of 16 products available. For example, the L-band VOD, which is related to water content in vegetation, is being used to better understand water exchanges in the soil–vegetation–atmosphere continuum.
      The SMAP Active–Passive (AP) algorithm – based on data from SMAP and the European Copernicus Program Sentinel-1 C-band synthetic aperture radar (SAR) – will be adapted to work with L-band data from the newly launched NISAR mission. The result will be estimates of global soil moisture at a spatial resolution of 1 km (0.62 mi) or better approximately once per week.
      In addition, the data collected during the SMAP mission would be continued and further enhanced by the European Union’s Copernicus Imaging Microwave Radiometer (CIMR) mission if it launches. This proposed multichannel microwave radiometry observatory includes L-band and four other microwave channels sharing a large mesh reflector – like the one used with SMAP. The plan calls for CIMR to follow a similar approach as SMAP for RFI detection and meet the instrument thermal noise and data latency of SMAP for next-mission desired characteristics.
      To learn more about what SMAP has accomplished see “A Decade of Global Water Cycle Monitoring: NASA Soil Moisture Active Passive Mission.”
      NASA’s Orbiting Carbon Observatory-2 (OCO-2) has been the “gold standard” for atmospheric carbon dioxide (CO2) observations from space for over a decade. The data returned from OCO-2 provide insights into plant health, forest management, forecasting crop yields, fire-risk models, and anticipating droughts. 
      OCO-3, constructed from spare parts left after OCO-2, was launched to the International Space Station (ISS) in 2019, where it has operated for over five years. OCO-3 extends the global CO2 measurement record while adding new capabilities made possible by being on ISS (e.g., detailed views of urban and tropical regions). 
      The overarching OCO mission hasn’t just about been about data and hardware. Although both those elements are parts of the story, the human stories woven through the mission’s successes and setbacks are really what holds the mission together. The feature, “A Tapestry of Tales: 10th Anniversary Reflections from NASA’s OCO-2 Mission,” sheds light on some of these personal stories from the OCO-2 and OCO-3 missions.
      The individual tales contained in this article reveal the grit and determination behind the scenes of the success of OCO-2 and OCO-3, from the anxiety and excitement surrounding the launch of OCO-2, to moments of fieldwork in the Nevada desert, to internships where wildfire responders turned to OCO-2 data to improve fire-risk models. Taken together, these stories form a “tapestry” that reveals how the OCO-2 and OCO-3 missions continue to illuminate the dynamics of Earth’s atmosphere – one breath at a time.
      These personal perspectives underscore that science is not just numbers; it’s people pushing boundaries, navigating failure, and inspiring ways to make our planet safer and healthier. In a time such as this, this is an important reminder.
      The joint NASA–U.S. Geological Survey (USGS) Landsat program has been a cornerstone of Earth observation for over 50 years. On July 13, Landsat 9 collected its millionth image: a stunning shot of the Arctic National Wildlife Refuge in Alaska – see Figure. Landsat 9, the most recent satellite in the Landsat series, orbits Earth alongside Landsat 8. Together, these satellites collect invaluable data about Earth’s changing land surface every eight days.
      Figure: This Landsat 9 image showing the Beaufort Sea shoreline off Alaska and Canada is just one of the scenes captured and processed on July 13, 2025— the same day the USGS EROS archive reached a milestone of one million Landsat 9 Level-1 products. This false color image was made with bands 6, 5, and 4 from the Operational Land Imager. This remote area allows the pristine wilderness environment to support a diverse wildlife and unique ecosystem that includes various species of mammals, birds, and fish. Landsat Level-1 products from Landsat 1 through Landsat 9 can be downloaded at no charge from a number of systems – visit the Landsat Data Access webpage to learn more.  Credit: Public Domain After collecting more than 3.3 million images over the course of more than 26 years in orbit, Landsat 7 was decommissioned on June 4, 2025. A YouTube video released at the time of decommissioning provides a concise visual summary of the Landsat 7 mission’s achievements – and the technical challenges overcome. In addition, The Earth Observer did a feature for the 20th anniversary of Landsat 7 in the July–August 2019 issue, called “The Living Legacy of Landsat 7: Still Going Strong After 20 Years in Orbit” [Volume 31, Issue 4, pp. 4–14] that is a useful resource to learn more about the history and achievements (through 20 years) of the mission.
      One of the strengths of the Landsat program is its potential for data integration with other satellites. The Harmonized Landsat and Sentinel-2 (HLS) product exemplifies this collaborative approach by combining data from Landsat 8 and 9 with data from the European Space Agency’s Copernicus Sentinel-2 A, B, and C missions. Whereas Landsat alone has a repeat time of eight days (i.e., combining Landsat 8 and 9 data); the combined HLS dataset provides imagery for the same location on Earth every 1.6 days – enabling researchers to monitor short-term changes in Earth’s land surface much more effectively than using Landsat or Sentinel-2 data alone.
      HLS became one of the most-downloaded NASA data products in fiscal year 2024, with continued growth on the horizon. In February 2025, the program expanded with nine new vegetation indices based on HLS data, with historical processing back to 2013 scheduled for completion by early 2026. Low-latency HLS products will also be available in late 2026. For the full story of how HLS came to be – see the feature: “Harmonized Landsat and Sentinel-2: Collaboration Drives Innovation.”
      Following a 13-month hibernation, the Global Ecosystem Dynamics Investigation (GEDI) mission was reinstalled to its original location aboard the ISS and resumed operations on April 22, 2024. Since this storage period, GEDI’s lasers have been operating nominally and the mission has continued to produce high-quality observations of the Earth’s three-dimensional structure, amassing 33 billion land surface returns as of November 27, 2024.
      The mission team has been actively processing and releasing post-storage data to the public, with Version 2.1 – GEDI L1B, L2A, L2B, and L4A data products, which include data through November 2024, all available for download. The new L4C footprint-level Waveform Structural Complexity Index (WSCI) product using pre-storage data has also been released. Looking ahead, the team is preparing Version 3.0 (V3) of all data products, which will incorporate post-storage data while improving quality filtering, geolocation accuracy, and algorithm performance.
      The 2025 GEDI Science Team Meeting (STM) brought together the mission science team, competed science team, representatives from the distributed active archive centers (DAACs), collaborators, stakeholders, and data users. Notably, it marked the first in-person gathering of the second competed science team, who shared updates on their research projects. The STM held an important space for brainstorming, knowledge-sharing, and discussion as the GEDI mission continues to flourish in its second epoch. To learn more, see “Summary of the 2025 GEDI Science Team Meeting.”
      Shifting focus to the boreal forests of North America, the NASA Arctic–Boreal Vulnerability Experiment (ABoVE) is now in its final year, marking the end of a decade-long scientific endeavor that has transformed our understanding of environmental change in Alaska and western Canada. This ambitious campaign, funded primarily by NASA’s Terrestrial Ecology Program, has successfully progressed through three distinct phases: ecosystem dynamics (2015–2018), ecosystem services (2017–2022), and the current analysis and synthesis phase (2023–present).
      As ABoVE approaches its conclusion, the program has grown to encompass 67 NASA-funded projects with over 1000 participating researchers – a testament to the collaborative scale required to address complex Arctic–boreal ecosystem questions. The program’s integrated approach, combining field research, airborne campaigns, and satellite remote sensing, has generated unprecedented insights into how environmental changes in these northern regions affect both vulnerable ecosystems and society.
      The recent 11th – and final – ABoVE Science Team Meeting was an opportunity to showcase the program’s evolution from data collection to synthesis, highlighting successful community engagement initiatives, cutting-edge research on carbon dynamics and ecosystem responses, and innovative science communication strategies that have made this complex research accessible to diverse audiences. With synthesis activities now underway, ABoVE is positioned to deliver comprehensive insights that will inform Arctic and boreal research for years to come. To learn more, see “Summary of the 11th and Final ABoVE Science Team Meeting.”
      Last but certainly not least, I want to both recognize and congratulate Compton J. Tucker [GSFC—Senior Researcher]. Compton retired from NASA in March 2025 after 48 years of public service, and then in April, was among 149 newly elected members to the National Academy of Sciences (NAS) – which is one of the highest honors in American science. This recognition from NAS brings Compton’s career full circle. He came to GSFC as a NAS postdoc before joining NASA as a civil servant. Compton is a pioneer in the field of satellite-based environmental analysis, using data from various Landsat missions and from the National Oceanographic and Atmospheric Administration’s (NOAA) Advanced Very High Resolution Radiometer (AVHRR) instrument. His research has focused on global photosynthesis on land, determining land cover, monitoring droughts and food security, and evaluating ecologically coupled disease outbreaks. The Kudos, “Compton J. Tucker Retires from NASA and is Named NAS Fellow,” provides more details about Compton’s research achievements and all of the other scientific awards and honors received throughout his career.

      Artwork: NASA, ESA, CSA, STScI, Joseph Olmsted (STScI) Scientists are in the midst of observing the exoplanet TRAPPIST-1 e with NASA’s James Webb Space Telescope. Careful analysis of the results so far presents several potential scenarios for what the planet’s atmosphere and surface may be like, as NASA science missions lay key groundwork to answer the question, “are we alone in the universe?” 
      “Webb’s infrared instruments are giving us more detail than we’ve ever had access to before, and the initial four observations we’ve been able to make of planet e are showing us what we will have to work with when the rest of the information comes in,” said Néstor Espinoza of the Space Telescope Science Institute in Baltimore, Maryland, a principal investigator on the research team. Two scientific papers detailing the team’s initial results are published in the Astrophysical Journal Letters.
      Image A: Trappist-1 e (Artist’s Concept)
      This artist’s concept shows the volatile red dwarf star TRAPPIST-1 and its four most closely orbiting planets, all of which have been observed by NASA’s James Webb Space Telescope. Webb has found no definitive signs of an atmosphere around any of these worlds yet.  Artwork: NASA, ESA, CSA, STScI, Joseph Olmsted (STScI) Of the seven Earth-sized worlds orbiting the red dwarf star TRAPPIST-1, planet e is of particular interest because it orbits the star at a distance where water on the surface is theoretically possible — not too hot, not too cold — but only if the planet has an atmosphere. That’s where Webb comes in. Researchers aimed the telescope’s powerful NIRSpec (Near-Infrared Spectrograph) instrument at the system as planet e transited, or passed in front of, its star. Starlight passing through the planet’s atmosphere, if there is one, will be partially absorbed, and the corresponding dips in the light spectrum that reaches Webb will tell astronomers what chemicals are found there. With each additional transit, the atmospheric contents become clearer as more data is collected. 
      Primary atmosphere unlikely
      Though multiple possibilities remain open for planet e because only four transits have been analyzed so far, the researchers feel confident that the planet does not still have its primary, or original, atmosphere. TRAPPIST-1 is a very active star, with frequent flares, so it is not surprising to researchers that any hydrogen-helium atmosphere with which the planet may have formed would have been stripped off by stellar radiation. However many planets, including Earth, build up a heavier secondary atmosphere after losing their primary atmosphere. It is possible that planet e was never able to do this and does not have a secondary atmosphere. Yet researchers say there is an equal chance there is an atmosphere, and the team developed novel approaches to working with Webb’s data to determine planet e’s potential atmospheres and surface environments. 
      World of (fewer) possibilities
      The researchers say it is unlikely that the atmosphere of TRAPPIST-1 e is dominated by carbon dioxide, analogous to the thick atmosphere of Venus and the thin atmosphere of Mars. However, the researchers also are careful to note that there are no direct parallels with our solar system.
      “TRAPPIST-1 is a very different star from our Sun, and so the planetary system around it is also very different, which challenges both our observational and theoretical assumptions,” said team member Nikole Lewis, an associate professor of astronomy at Cornell University. 
      If there is liquid water on TRAPPIST-1 e, the researchers say it would be accompanied by a greenhouse effect, in which various gases, particularly carbon dioxide, keep the atmosphere stable and the planet warm.  
      “A little greenhouse effect goes a long way,” said Lewis, and the measurements do not rule out adequate carbon dioxide to sustain some water on the surface. According to the team’s analysis, the water could take the form of a global ocean, or cover a smaller area of the planet where the star is at perpetual noon, surrounded by ice. This would be possible because, due to the TRAPPIST-1 planets’ sizes and close orbits to their star, it is thought that they all are tidally locked, with one side always facing the star and one side always in darkness.

Narrow colored bands show the most likely locations of data points for each model. Illustration: NASA, ESA, CSA, STScI, Joseph Olmsted (STScI) Innovative new method
      Espinoza and co-principal investigator Natalie Allen of Johns Hopkins University are leading a team that is currently making 15 additional observations of planet e, with an innovative twist. The scientists are timing the observations so that Webb catches both planets b and e transiting the star one right after the other. After previous Webb observations of planet b, the planet orbiting closest to TRAPPIST-1, scientists are fairly confident it is a bare rock without an atmosphere. This means that signals detected during planet b’s transit can be attributed to the star only, and because planet e transits at nearly the same time, there will be less complication from the star’s variability. Scientists plan to compare the data from both planets, and any indications of chemicals that show up only in planet e’s spectrum can be attributed to its atmosphere. 
      “We are really still in the early stages of learning what kind of amazing science we can do with Webb. It’s incredible to measure the details of starlight around Earth-sized planets 40 light-years away and learn what it might be like there, if life could be possible there,” said Ana Glidden, a post-doctoral researcher at Massachusetts Institute of Technology’s Kavli Institute for Astrophysics and Space Research, who led the research on possible atmospheres for planet e. “We’re in a new age of exploration that’s very exciting to be a part of,” she said.
      The four transits of TRAPPIST-1 e analyzed in the new papers published today were collected by the JWST Telescope Scientist Team’s DREAMS (Deep Reconnaissance of Exoplanet Atmospheres using Multi-instrument Spectroscopy) collaboration.
      The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

      NASA and Northrop Grumman are preparing to send the company’s next cargo mission to the International Space Station, flying research to support Artemis missions to the Moon and human exploration of Mars and beyond, while improving life on Earth. SpaceX’s Falcon 9 rocket will launch Northrop Grumman’s 23rd commercial resupply services mission to the orbiting laboratory.
      The investigations aboard the Cygnus spacecraft aim to refine semiconductor crystals for next-generation technologies, reduce harmful microbes, improve medication production, and manage fuel pressure.
      NASA, Northrop Grumman, and SpaceX are targeting launch in mid-September from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.
      Read about some of the investigations traveling to the space station:
      Better semiconductor crystals
      Optical micrograph of a semiconductor composite wafer with embedded semimetal phases extracted from a space grown crystal in the SUBSA facility during Mission 1United Semiconductors LLC Researchers are continuing to fine-tune in-space production of semiconductor crystals, which are critical for modern devices like cellphones and computers.
      The space station’s microgravity environment could enable large-scale manufacturing of complex materials, and leveraging the orbiting platform for crystal production is expected to lead to next-generation semiconductor technologies with higher performance, chip yield, and reliability.
      “Semiconductor devices fabricated using crystals from a previous mission demonstrated performance gain by a factor of two and device yield enhanced by a factor of 10 compared to Earth-based counterparts,” said Partha S. Dutta, principal investigator, United Semiconductors LLC in Los Alamitos, California.
      Dutta highlighted that three independent parties validated microgravity’s benefits for growing semiconductor crystals and that the commercial value of microgravity-enhanced crystals could be worth more than $1 million per kilogram (2.2 pounds).
      Space-manufactured crystals could help meet the need for radiation-hardened, low-power, high-speed electronics and sensors for space systems. They also could provide reduced power use, increased speed, and improved safety. The technology also has ground applications, including electric vehicles, waste heat recovery, and medical tools.

      Lethal light
      Germicidal Ultraviolet (UV) light is emitted by an optical fiber running through the center of an agar plateArizona State University Researchers are examining how microgravity affects ultraviolet (UV) light’s ability to prevent the formation of biofilms — communities of microbes that form in water systems. Investigators developed special optical fibers to deliver the UV light, which could provide targeted, long-lasting, and chemical-free disinfection in space and on Earth.
      “In any water-based system, bacterial biofilms can form on surfaces like pipes, valves, and sensors,” said co-investigator Paul Westerhoff, a professor at Arizona State University in Tempe. “This can cause serious problems like corrosion and equipment failure, and affect human health.”
      The UV light breaks up DNA in microorganisms, preventing them from reproducing and forming biofilms. Preliminary evidence suggests biofilms behave differently in microgravity, which may affect how the UV light reaches and damages bacterial DNA.
      “What we’ll learn about biofilms and UV light in microgravity could help us design safer water and air systems not just for space exploration, but for hospitals, homes, and industries back on Earth,” Westerhoff said.

      Sowing seeds for pharmaceuticals
      NASA astronaut Loral O’Hara displays the specialized sample processor used for pharmaceutical research aboard the International Space StationNASA An investigation using a specialized pharmaceutical laboratory aboard the space station examines how microgravity may alter and enhance crystal structures of drug molecules. Crystal structure can affect the production, storage, effectiveness, and administration of medications.
      “We are exploring drugs with applications in cardiovascular, immunologic, and neurodegenerative disease as well as cancer,” said principal investigator Ken Savin of Redwire Space Technologies in Greenville, Indiana. “We expect microgravity to yield larger, more uniform crystals.”
      Once the samples return to Earth, researchers at Purdue University in West Lafayette, Indiana, will examine the crystal structures.
      The investigators hope to use the space-made crystals as seeds to produce significant numbers of crystals on Earth.
      “We have demonstrated this technique with a few examples, but need to see if it works in many examples,” Savin said. “It’s like being on a treasure hunt with every experiment.”
      This research also helps enhance and expand commercial use of the space station for next-generation biotechnology research and in-space production of medications.

      Keeping fuel cool
      iss0NASA astronaut Joe Acaba installs hardware for the first effort in 2017 aboard the International Space Station to test controlling pressure in cryogenic fuel tanksNASA Many spacecraft use cryogenic or extremely cold fluids as fuel for propulsion systems. These fluids are kept at hundreds of degrees below zero to remain in a liquid state, making them difficult to use in space where ambient temperatures can vary significantly. If these fluids get too warm, they turn into gas and boiloff, or slowly evaporate and escape the tank, affecting fuel efficiency and mission planning.
      A current practice to prevent this uses  onboard fuel to cool systems before transferring fuel, but this practice is wasteful and not feasible for Artemis missions to the Moon and future exploration of Mars and beyond. A potential alternative is using special gases that do not turn into liquids at cold temperatures to act as a barrier in the tank and control the movement of the fuel.
      Researchers are testing this method to control fuel tank pressure in microgravity. It could save an estimated 42% of propellant mass per year, according to Mohammad Kassemi, a researcher at NASA’s National Center for Space Exploration Research and Case Western Reserve University in Cleveland.
      The test could provide insights that help improve the design of lightweight, efficient, long-term in-space cryogenic storage systems for future deep space exploration missions.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      Researchers Kelly Gilkey, Cy Peverill, Daniel Phan, Chase Haddix, and Ariel Tokarz test portable, handheld X-ray systems for use during future long-duration space missions at NASA’s Glenn Research Center in Cleveland on Friday, March 21, 2025. Credit: NASA/Sara Lowthian-Hanna As NASA plans future human exploration missions to the Moon, Mars, and beyond, new and unique challenges emerge — like communication delays and limited return-to-Earth options — so enhanced medical care capabilities are critical. Crews will need non-invasive imaging technology to diagnose medical conditions, like broken bones or dental injuries.  
      Scientists at NASA’s Glenn Research Center in Cleveland are testing portable, handheld X-ray systems for use during future extended space missions. Having portable X-ray capabilities aboard spacecraft would allow astronauts to immediately assess and treat potential injuries or identify equipment issues without having to disassemble the gear. 
      “Technological innovations like that of the mini-X-ray will help keep our astronauts healthy as we endeavor farther into space than ever before,” said acting NASA Administrator Sean Duffy. “Future missions to the Moon and Mars will be safer due to the research of our scientists at NASA Glenn.” 
      NASA reviewed more than 200 commercial systems — analyzing size, weight, image quality, ease-of-use, cost, and safety — and selected three systems for further testing: MinXray, Remedi, and Fujifilm. 
      “We’re working to provide evidence on why a mini-X-ray system should be included in future space exploration,” said Dr. Chase Haddix, a senior biomedical engineering research contractor working for Universities Space Research Association at NASA Glenn. “These X-rays could be used to detect both clinical and non-clinical diagnostics, meaning they can check an astronaut’s body or identify the location of a tear in an astronaut suit.”

Credit: NASA/Sara Lowthian-Hanna NASA Glenn is collaborating with other centers, including NASA’s Johnson Space Center in Houston and NASA’s Langley Research Center in Hampton, Virginia, and radiography experts at University Hospitals and Cuyahoga Community College in Cleveland. 
      “We’re fortunate to have enthusiastic medical and radiography experts right here in our community,” said Dr. Cy Peverill, project task lead at NASA Glenn. “Their knowledge and experience are invaluable as we work to test medical technologies that could significantly improve management of astronaut health on future missions to the Moon or Mars.” 
      Cuyahoga Community College contributed anatomical phantoms, which are lifelike models of the human body, in its radiography laboratory on the Western Campus and dental hygiene clinical facility at the Metropolitan Campus. Faculty and students consulted with NASA researchers on essential imaging principles, including patient positioning, image acquisition, and image quality.   
      University Hospitals is partnering with NASA Glenn on a medical study with real patients to compare the performance of the X-ray systems against hospital-grade equipment, focusing on usability, image clarity, and diagnostic accuracy.   
      “Astronauts live and work in small quarters, much smaller spaces than in a hospital,” Haddix said. “The system must be easy to use since astronauts may not be experienced in radiography. The data from these tests will guide the selection of the most suitable system for future missions.”

Credit: NASA/Sara Lowthian-Hanna Using portable X-rays to improve health care in inaccessible areas is not new, with systems deployed to diagnose medical issues in places such as base camps in Nepal and remote villages in South Africa. NASA researchers theorize that if these systems are successful in high elevations and extreme temperatures on Earth, perhaps they are durable enough for space missions. 
      Glenn researchers will continue to collect data from all collaborators, including from an X-ray system sourced by SpaceX that launched in April during the Fram2 mission. The crew captured the first human X-ray images in space during their four-day mission to low Earth orbit. NASA plans to select a device near the end of 2025 and will test the chosen system aboard the International Space Station in 2026 or early 2027.  
      The Mars Campaign Office at NASA Headquarters in Washington and the agency’s Human Research Program at NASA Johnson fund this work as both organizations focus on pursuing technologies and methods to support safe, productive human space travel.
