Captured at a location called “Falbreen,” this enhanced-color mosaic features decep-tively blue skies and the 43rd rock abrasion (the white patch at center-left) of the NASA Perseverance rover’s mission at Mars. The 96 images stitched together to create this 360-degree view were acquired May 26, 2025.NASA/JPL-Caltech/ASU/MSSS In this natural-color version of the “Falbreen” panorama, colors have not been enhanced and the sky appears more reddish.

‘Float rocks,’ sand ripples, and vast distances are among the sights to see in the latest high-resolution panorama by the six-wheeled scientist.

The imaging team of NASA’s Perseverance Mars rover took advantage of clear skies on the Red Planet to capture one of the sharpest panoramas of its mission so far. Visible in the mosaic, which was stitched together from 96 images taken at a location the science team calls “Falbreen,” are a rock that appears to lie on top of a sand ripple, a boundary line between two geologic units, and hills as distant as 40 miles (65 kilometers) away. The enhanced-color version shows the Martian sky to be remarkably clear and deceptively blue, while in the natural-color version, it’s reddish.

“Our bold push for human space exploration will send astronauts back to the Moon,” said Sean Duffy, acting NASA administrator. “Stunning vistas like that of Falbreen, captured by our Perseverance rover, are just a glimpse of what we’ll soon witness with our own eyes. NASA’s groundbreaking missions, starting with Artemis, will propel our unstoppable journey to take human space exploration to the Martian surface. NASA is continuing to get bolder and stronger.”

The rover’s Mastcam-Z instrument captured the images on May 26, 2025, the 1,516th Martian day, or sol, of Perseverance’s mission, which began in February 2021 on the floor of Jezero Crater. Perseverance reached the top of the crater rim late last year.

“The relatively dust-free skies provide a clear view of the surrounding terrain,” said Jim Bell, Mastcam-Z’s principal investigator at Arizona State University in Tempe. “And in this particular mosaic, we have enhanced the color contrast, which accentuates the differences in the terrain and sky.”

One detail that caught the science team’s attention is a large rock that appears to sit atop a dark, crescent-shaped sand ripple to the right of the mosaic’s center, about 14 feet (4.4 meters) from the rover. Geologists call this type of rock a “float rock” because it was more than likely formed someplace else and transported to its current location. Whether this one arrived by a landslide, water, or wind is unknown, but the science team suspects it got here before the sand ripple formed.

The bright white circle just left of center and near the bottom of the image is an abrasion patch. This is the 43rd rock Perseverance has abraded since it landed on Mars. Two inches (5 centimeters) wide, the shallow patch is made with the rover’s drill and enables the science team to see what’s beneath the weathered, dusty surface of a rock before deciding to drill a core sample that would be stored in one of the mission’s titanium sample tubes.

The rover made this abrasion on May 22 and performed proximity science (a detailed analysis of Martian rocks and soil) with its arm-mounted instruments two days later. The science team wanted to learn about Falbreen because it’s situated within what may be some of the oldest terrain Perseverance has ever explored — perhaps even older than Jezero Crater.

Tracks from the rover’s journey to the location can be seen toward the mosaic’s right edge. About 300 feet (90 meters) away, they veer to the left, disappearing from sight at a previous geologic stop the science team calls “Kenmore.”

A little more than halfway up the mosaic, sweeping from one edge to the other, is the transition from lighter-toned to darker-toned rocks. This is the boundary line, or contact, between two geologic units. The flat, lighter-colored rocks nearer to the rover are rich in the mineral olivine, while the darker rocks farther away are believed to be much older clay-bearing rocks.

NASA Astronaut Barry “Butch” WilmoreNASA/Aubrey Gemignani

After 25 years at NASA, flying in four different spacecraft, accumulating 464 days in space, astronaut and test pilot Butch Wilmore has retired from NASA.

The Tennessee native earned a bachelor’s and a master’s degree in electrical engineering from Tennessee Technological University and a master’s degree in aviation systems from the University of Tennessee.

Wilmore is a decorated U.S. Navy captain who has flown numerous tactical aircraft operationally while deploying aboard four aircraft carriers during peacetime and combat operations. A graduate of the U.S. Naval Test Pilot School, he went on to serve as a test pilot before NASA selected him to become an astronaut in 2000.

“Butch’s commitment to NASA’s mission and dedication to human space exploration is truly exemplary,” said Steve Koerner, acting director of NASA’s Johnson Space Center in Houston. “His lasting legacy of fortitude will continue to impact and inspire the Johnson workforce, future explorers, and the nation for generations. On behalf of NASA’s Johnson Space Center, we thank Butch for his service.”

During his time at NASA, Wilmore completed three missions launching aboard the space shuttle Atlantis, Roscosmos Soyuz, and Boeing Starliner to the International Space Station. Wilmore also returned to Earth aboard a SpaceX Dragon spacecraft. Additionally, he conducted five spacewalks, totaling 32 hours outside the orbital laboratory.  

“Throughout his career, Butch has exemplified the technical excellence of what is required of an astronaut. His mastery of complex systems, coupled with his adaptability and steadfast commitment to NASA’s mission, has inspired us all,” said Joe Acaba, chief of the Astronaut Office at NASA Johnson. “As he steps into this new chapter, that same dedication will no doubt continue to show in whatever he decides to do next.”

Most recently, Wilmore launched aboard Boeing’s Starliner spacecraft on June 5, 2024, for its first crewed flight test mission, arriving at the space station the following day. While aboard the station, Wilmore completed numerous tasks, including a spacewalk to help remove a radio frequency group antenna assembly from the station’s truss and collected samples and surface material for analysis from the Destiny laboratory and the Quest airlock.

“From my earliest days, I have been captivated by the marvels of creation, looking upward with an insatiable curiosity. This curiosity propelled me into the skies, and eventually to space, where the magnificence of the cosmos mirrored the glory of its creator in ways words can scarcely convey,” said Wilmore. “Even as I ventured beyond Earth’s limits, I remained attuned to the beauty and significance of the world below, recognizing the same intricate design evident among the stars is also woven into the fabric of life at home.”

This view of tracks trailing NASA’s Curiosity rover was captured July 26, 2025, as the rover simultaneously relayed data to a Mars orbiter.NASA/JPL-Caltech

NASA’s Curiosity rover captured a view of its tracks on July 26, 2025. The robotic scientist is now exploring a region of lower Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain. The pale peak of the mountain can be seen at top right; the rim of Gale Crater, within which the mountain sits, is on the horizon at top left. Curiosity touched down on the crater floor 13 years ago.

Recently, the rover rolled into a region filled with boxwork formations. Studying these formations could reveal whether microbial life could have survived in the Martian subsurface eons ago, extending the period of habitability farther into when the planet was drying out.

Nathan Jermyn frequented NASA Stennis on field trips when he was younger. Now, he works as an attorney-advisor supporting NASA Stennis and the NASA Shared Services Center. NASA/Danny Nowlin

Before Nathan Jermyn could dig into the legal frameworks at NASA, he had to answer a different call.

Jermyn participated in a one-day orientation in the summer of 2023 to begin work as an attorney-advisor supporting NASA’s Stennis Space Center and the NASA Shared Services Center near Bay St. Louis, Mississippi.

However, the Biloxi, Mississippi, native shipped out just a week later with the Mississippi Army National Guard to provide military legal counsel for nearly six months in support of Operation Spartan Shield and Operation Inherent Resolve.

The decorated military veteran returned to NASA in January 2024 to fully immerse himself as a member of the contract and procurement practice group for the NASA Office of the General Counsel.

“Even though I have been working here for two years, sometimes it does not feel real,” Jermyn said.

As a member of the contract and procurement law team, Jermyn assists with contract- and procurement-related topics for NASA Stennis and the NASA Shared Services Center to ensure taxpayer funds are used responsibly.

He also is a member of NASA’s Freedom of Information Act (FOIA) team and provides legal reviews and advice for FOIA requests as the agency creates a cohesive and effective knowledge-sharing environment.

The most interesting thing about his work is seeing how the big picture comes together, how each small detail and decision adds up to something more meaningful.  

“Our office is a small piece, and it is amazing to see how our efforts intertwine with NASA Stennis and the NASA Shared Services Center operations and NASA,” he said. “It is also amazing the lengths everyone will go to help each other accomplish the mission.”

Before joining NASA, Jermyn graduated from The University of Southern Mississippi with a bachelor’s degree in business administration and a law degree from Mississippi College School of Law.

The Gulfport, Mississippi, resident initially practiced criminal law. Jermyn credits the team he works with at NASA for helping him navigate the complexities of government contract law.

“Having a team that supports you and teaches you every day really expedites the learning process,” he said. “Our team puts a heavy emphasis on learning, development, and teamwork.”

Jermyn is most excited to see how NASA continues to explore the universe moving forward, which includes the Artemis campaign of exploring the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars. Artemis II is scheduled for 2026.

“I wholeheartedly believe humanity is destined for the stars and NASA is in prime position to lead that charge,” he said.

Curiosity Blog, Sols 4618-4619: The Boxwork Structures Continue to Call to Us NASA’s Mars rover Curiosity acquired this image using its Left Navigation Camera on Aug. 1, 2025 — Sol 4616, or Martian day 4,616 of the Mars Science Laboratory mission — at 03:36:56 UTC.NASA/JPL-Caltech

Written by Ashley Stroupe, Mission Operations Engineer and Rover Planner at NASA’s Jet Propulsion Laboratory

Earth planning date: Friday, Aug. 1, 2025.

Now that we have reached August, our “landiversary” (anniversary of landing — Aug. 5 PDT) is less than a week away! The team is looking forward to being able to celebrate the milestone of our rover becoming a teenager at 13. Today’s image is a beautiful back-lit late afternoon image of the nearby mountains and the distant crater rim. These views make working on Mars never get old!

The first sol of today’s plan is very busy because we will only have data from the first sol down in time for planning on Monday. Today I was working as a Rover Planner, supporting both arm and drive activities. We start first thing with arm activities; we DRT brush and do APXS integration on the target “San Cristóbal,” which is a bedrock target, and the only place in the workspace smooth and flat enough for us to brush. 

After a brief nap, we have an extensive imaging campaign. We take Mastcam images of the AEGIS target from the previous plan and two potential vein targets “Rio Satja” and “Río Ichilo.”  We then take Mastcam stereo mosaics of boxwork targets “Pontezuelo” and “Catedrales de Tara.”  Additionally we have stereo mosaics of “Llanos de Challe,” a transition between the bedrock in the boxwork hollow and the boxwork ridge, a nearby light-toned exposure, and some additional troughs and ridges. ChemCam then takes a LIBS observation of “Airport Domes,” which is another hollow in the boxworks. Finally, we take a ChemCam RMI and a Mastcam of Pontezuelo.

After finishing all the imaging, we continue with the rest of the arm activities. We split the arm activities to accommodate conflicting constraints — both APXS and ChemCam both need to be as early as possible. In this set of arm activities, we begin with MAHLI imaging of the two targets, San Cristóbal and “Salar de Agua Amara,” which consists of delicate branching structures likely made by groundwater. 

After another short nap, we do a small adjustment in our position to get another interesting piece of bedrock ridge in our workspace. In order to approach it at a good angle, we first drive parallel to the ridge to be lined up with the target, and then we turn and drive straight to it. Due to constraints on how we like to park at targets, sometimes these shorter drives can be more complicated than longer ones — but today it was simpler. After completing the drive, we unstow the arm to get a clear view of our workspace for Monday’s planning as well as our standard post-drive imaging and then Curiosity goes to sleep for the night. 

The second sol of the plan is a bit more leisurely. Around midday, Curiosity will be taking some atmospheric observations, including a Navcam dust-devil survey and a south-facing suprahorizon movie, followed by an AEGIS activity where the rover gets to pick targets and observe them herself. Then, early the next morning, Curiosity will wake up to take some additional atmospheric observations, including Navcam zenith and suprahorizon movies, Navcam line-of-sight toward the crater rim, and a Mastcam solar tau to measure dust in the atmosphere. Finally, she’ll get a short nap before waking up to start the next plan.

NASA has selected six companies to produce studies focused on lower-cost ways to launch and deliver spacecraft of various sizes and forms to multiple, difficult-to-reach orbits.

The firm-fixed-price awards comprise nine studies with a maximum total value of approximately $1.4 million. The awardees are:

• Arrow Science and Technology LLC, Webster, Texas
• Blue Origin LLC, Merritt Island, Florida
• Firefly Aerospace Inc., Cedar Park, Texas
• Impulse Space Inc., Redondo Beach, California
• Rocket Lab, Long Beach, California
• United Launch Services LLC, Centennial, Colorado

“With the increasing maturity of commercial space delivery capabilities, we’re asking companies to demonstrate how they can meet NASA’s need for multi-spacecraft and multi-orbit delivery to difficult-to-reach orbits beyond current launch service offerings,” said Joe Dant, orbital transfer vehicle strategic initiative owner for the Launch Services Program at NASA’s Kennedy Space Center in Florida. “This will increase unique science capability and lower the agency’s overall mission costs.”

Each of the six companies will deliver studies exploring future application of orbital transfer vehicles for NASA missions:

Arrow will partner with Quantum Space for its study. Quantum’s Ranger provides payload delivery service as a multi-mission spacecraft engineered for rapid maneuverability and adaptability, enabling multi-destination delivery for missions from low Earth orbit to lunar orbit.

Blue Origin will produce two studies, including one for Blue Ring, a large, high-mobility space platform providing full-service payload delivery, on-board edge computing, hosting, and end-to-end mission operations. It uses hybrid solar-electric and chemical propulsion capability to reach geostationary, cislunar, Mars, and interplanetary destinations. The second is a New Glenn upper stage study.

Firefly’s line of Elytra orbital vehicles offers on-demand payload delivery, imaging, long-haul communications, and domain awareness across cislunar space. Firefly’s Elytra Dark is equipped to serve as a transfer vehicle and enable ongoing operations in lunar orbit for more than five years.

Impulse Space will produce two studies. The company provides in-space mobility with two vehicles, Mira and Helios. Mira is a high-thrust, highly maneuverable spacecraft for payload hosting and deployment, while Helios is a high-energy kick stage to rapidly deliver payloads from low Earth to medium Earth orbits, geostationary orbits and beyond.

Rocket Lab’s two studies will feature the upper stage of the company’s Neutron rocket, as well as a long-life orbital transfer vehicle based on its Explorer spacecraft. Both vehicles are equipped with their own propulsion systems and other subsystems for missions to medium Earth and geosynchronous orbit and deep space destinations like the Moon, Mars, and near-Earth asteroids.

United Launch Alliance will assess the cislunar mission capabilities of an extended-duration Centaur V upper stage. Centaur would be capable of directly delivering multiple rideshare spacecraft to two different orbital destinations in cislunar space, avoiding the need for an additional rocket stage or orbital transfer vehicle.

The studies will be complete by mid-September. NASA will use the findings to inform mission design, planning, and commercial launch acquisition strategies for risk-tolerant payloads, with a possibility of expanding delivery services to larger-sized payloads and to less risk-tolerant missions in the future.

NASA’s Launch Services Program selected providers through the agency’s VADR (Venture-Class Acquisition of Dedicated and Rideshare Launch Services) contract, which helps foster growth of the U.S. commercial launch market, enabling greater access to space at a lower cost for science and technology missions.

NASA has selected six companies to produce studies focused on lower-cost ways to launch and deliver spacecraft of various sizes and forms to multiple, difficult-to-reach orbits.

The firm-fixed-price awards comprise nine studies with a maximum total value of approximately $1.4 million. The awardees are:

• Arrow Science and Technology LLC, Webster, Texas
• Blue Origin LLC, Merritt Island, Florida
• Firefly Aerospace Inc., Cedar Park, Texas
• Impulse Space Inc., Redondo Beach, California
• Rocket Lab, Long Beach, California
• United Launch Services LLC, Centennial, Colorado

“With the increasing maturity of commercial space delivery capabilities, we’re asking companies to demonstrate how they can meet NASA’s need for multi-spacecraft and multi-orbit delivery to difficult-to-reach orbits beyond current launch service offerings,” said Joe Dant, orbital transfer vehicle strategic initiative owner for the Launch Services Program at NASA’s Kennedy Space Center in Florida. “This will increase unique science capability and lower the agency’s overall mission costs.”

Each of the six companies will deliver studies exploring future application of orbital transfer vehicles for NASA missions:

Arrow will partner with Quantum Space for its study. Quantum’s Ranger provides payload delivery service as a multi-mission spacecraft engineered for rapid maneuverability and adaptability, enabling multi-destination delivery for missions from low Earth orbit to lunar orbit.

Blue Origin will produce two studies, including one for Blue Ring, a large, high-mobility space platform providing full-service payload delivery, on-board edge computing, hosting, and end-to-end mission operations. It uses hybrid solar-electric and chemical propulsion capability to reach geostationary, cislunar, Mars, and interplanetary destinations. The second is a New Glenn upper stage study.

Firefly’s line of Elytra orbital vehicles offers on-demand payload delivery, imaging, long-haul communications, and domain awareness across cislunar space. Firefly’s Elytra Dark is equipped to serve as a transfer vehicle and enable ongoing operations in lunar orbit for more than five years.

Impulse Space will produce two studies. The company provides in-space mobility with two vehicles, Mira and Helios. Mira is a high-thrust, highly maneuverable spacecraft for payload hosting and deployment, while Helios is a high-energy kick stage to rapidly deliver payloads from low Earth to medium Earth orbits, geostationary orbits and beyond.

Rocket Lab’s two studies will feature the upper stage of the company’s Neutron rocket, as well as a long-life orbital transfer vehicle based on its Explorer spacecraft. Both vehicles are equipped with their own propulsion systems and other subsystems for missions to medium Earth and geosynchronous orbit and deep space destinations like the Moon, Mars, and near-Earth asteroids.

United Launch Alliance will assess the cislunar mission capabilities of an extended-duration Centaur V upper stage. Centaur would be capable of directly delivering multiple rideshare spacecraft to two different orbital destinations in cislunar space, avoiding the need for an additional rocket stage or orbital transfer vehicle.

The studies will be complete by mid-September. NASA will use the findings to inform mission design, planning, and commercial launch acquisition strategies for risk-tolerant payloads, with a possibility of expanding delivery services to larger-sized payloads and to less risk-tolerant missions in the future.

NASA’s Launch Services Program selected providers through the agency’s VADR (Venture-Class Acquisition of Dedicated and Rideshare Launch Services) contract, which helps foster growth of the U.S. commercial launch market, enabling greater access to space at a lower cost for science and technology missions.

7 Min Read NASA’s SpaceX Crew-10 Looks Back at Science Mission NASA’s SpaceX Crew-10 Looks Back at Science Mission

NASA’s SpaceX Crew-10 mission with agency astronauts Anne McClain and Nichole Ayers, JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov is preparing to return to Earth in early August after a long-duration mission aboard the International Space Station. During their stay, McClain, Ayers, and Onishi completed dozens of experiments and technology demonstrations, helping push the boundaries of scientific discovery aboard the orbiting laboratory.

Here’s a look at some scientific milestones accomplished during the Crew-10 mission:

Orbital effects on plants NASA

The canisters floating in the cupola of the International Space Station contain wild-type and genetically-modified thale cress plants for the Rhodium Plant LIFE experiment. The investigation studies how radiation and gravity environments at different orbital altitudes affect plant growth by comparing Crew-10 data with plants flown aboard the Polaris Dawn mission, which flew deeper into space. Studies have shown microgravity affects growth rates, and a better understanding of the mechanisms behind this could improve plant growth techniques in space and on Earth.

Solar spacewalk NASA

NASA astronaut Anne McClain conducts a spacewalk to upgrade the International Space Station’s power generation systems, which include main solar arrays like the one visible behind her. McClain is installing hardware to support an IROSA (International Space Station Roll-Out Solar Array), a type of array that is more compact and produces more power than the station’s original ones. The IROSAs were first demonstrated aboard the orbiting laboratory in June 2017, and eight have been installed to augment the power available for scientific research and other activities.

Microalgae on the menu NASA

NASA astronaut Nichole Ayers uses the International Space Station’s Space Automated Bioproduct Laboratory to process samples for SOPHONSTER, a study of microgravity’s effects on the protein yield of microalgae. These organisms are highly nutritious, producing amino acids, fatty acids, B vitamins, iron, and fiber. The microalgae could provide sustainable meat and dairy alternatives during long-duration space missions. It also could be used to make biofuels and bioactive compounds in medicines in space and on Earth.

Looking down on lightning NASA

The International Space Station orbits more than 250 miles above Earth, giving astronauts a unique view of their home planet, where they can photograph familiar places and interesting phenomena. While passing over a stormy night, NASA astronaut Nichole Ayers captured this image of simultaneous lightning at the top of two thunderstorms. Scientists use instruments installed on the space station to study lightning and other weather conditions in Earth’s upper atmosphere. This research helps protect communication systems and aircraft while improving atmospheric models and weather predictions.

In this time-lapse video, JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi and NASA astronaut Nichole Ayers harvest samples for the APEX-12 investigation, which examines how space radiation affects telomere activity in thale cress plants. Telomeres, which are repetitive DNA sequences that protect the ends of chromosomes, become shorter each time a cell divides and indicate cell aging. The APEX-12 investigation could clarify the role of telomeres in aging and diseases and help scientists equip plants and other organisms for the stress of long-duration spaceflight.

Microscopic motion NASA

A fluorescent microscope, known as ELVIS, captures the motion of microscopic algae and bacteria in 3D, a new capability aboard the International Space Station. The technology could be helpful in various applications in space and on Earth, such as monitoring water quality and detecting potentially infectious organisms. NASA astronaut Anne McClain prepares bacterial samples for viewing with the microscope.

How cells sense gravity NASA

Individual cells in our bodies can respond to the effects of gravity, but how they do this is largely unknown. The Cell Gravisensing investigation is an effort to observe the mechanism that enables cells to sense gravity and could lead to therapies to treat muscle and bone conditions, like muscle atrophy during long-duration spaceflight and osteoporosis on Earth. JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi processes research samples in the International Space Station’s Kibo laboratory module.

Water works NASA

NASA astronauts Nichole Ayers and Anne McClain work on installing hardware for the International Space Station’s Exploration Potable Water Dispenser. Scientists are evaluating the device’s water sanitization and microbial growth reduction technology. The dispenser provides room temperature and hot water for crew consumption and food preparation. This technology could be adopted for future exploration missions.

Free-flying camera NASA

Astronaut Takuya Onishi of JAXA (Japan Aerospace Exploration Agency) monitors the JEM Internal Ball Camera 2 as it floats through the International Space Station. The free-flying, rechargeable camera provides a visual field outside the other cameras installed aboard the space station. JAXA is testing the robot’s ability to capture video and imagery of scientific experiments and other activities, which could free up crew time for research and other duties.

Two rings to pin them all NASA

NASA astronaut Nichole Ayers sets up the space station’s Ring Sheared Drop device, which uses surface tension to pin a drop of liquid between two rings. The device makes it possible to study liquid proteins without a solid container, eliminating interactions between the solutions and container walls that can affect results. The Ring Sheared Drop-IBP-2 experiment studies the behavior of protein fluids in microgravity and tests predictive computer models. Better models could help advance manufacturing processes in space and on Earth for next-generation medicines to treat cancers and other diseases.

Crystallization research NASA

NASA astronaut Anne McClain swaps out hardware in the International Space Station’s Advanced Space Experiment Processor-4, which enables physical science and crystallization research. A current investigation uses the processor to demonstrate technology that may be able to produce medications during deep space missions and improve pharmaceutical manufacturing on Earth.

Monitoring astronaut health NASA

NASA astronaut Anne McClain helps JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi collect a sample of his blood. Analysis of blood samples is one tool NASA uses to continuously monitor crew health, including cardiovascular and immune system functions, bone and muscle mass changes, nutritional and metabolic status, and mental well-being. Crew members aboard the International Space Station also participate in various ongoing studies to better understand how different body systems adapt to weightlessness.

This animated, color-coded heat map shows temperature changes in the Sun’s outer atmosphere, or corona, over several days, with red indicating hotter regions and purple showing cooler ones. Scientists can observe these changes thanks to the International Space Station’s CODEX, which collected data during the Crew-10 mission. The instrument uses a coronagraph to block out sunlight and reveal details in the Sun’s corona. Data from this investigation could help scientists understand the energy source of the solar wind, a flow of charged particles from the Sun that constantly bombards Earth.

Expanding in-space crystallization NASA

Astronaut Takuya Onishi of JAXA (Japan Aerospace Exploration Agency) services the International Space Station’s Advanced Space Experiment Processor-4 in preparation for ADSEP-Industrial Crystallization Cassette. This investigation tests new hardware that scales up research and could enable in-space production of pharmaceuticals and other materials for commercial space applications.

Sowing seeds in space NASA

NASA astronaut Nichole Ayers prepares mixture tubes containing samples for Nanoracks Module-9 Swiss Chard. This student-designed experiment examines whether the size, shape, color, and nutritional content of Swiss chard seeds germinated in space differ from those grown on Earth. The International Space Station hosts ongoing plant research as a source of food and other benefits, including contributing to astronaut well-being, for future long-duration missions.

Protecting astronaut vision NASA

Spaceflight can cause changes to eye structure and vision, so crew members monitor eye health throughout their missions. Astronaut Takuya Onishi of JAXA (Japan Aerospace Exploration Agency), assisted by NASA astronaut Nichole Ayers, conducts an eye exam aboard the International Space Station using optical coherence tomography. This technology uses reflected light to produce 3D images of the retina, nerve fibers, and other eye structures and layers.

NASA Science Activation Teams Unite to Support Neurodiverse Learners with Public Libraries

On July 16, 2025, more than 400 public library staff from across the United States joined a powerful webinar, Serving Neurodiverse Library Patrons and Colleagues, hosted by two NASA Science Activation program teams: NASA@ My Library and NASA’s Neurodiversity Network (N3). The event brought together researchers, library professionals, and individuals with lived experience of neurodiversity to share insights and best practices for creating more inclusive and supportive environments in libraries.

Designed to equip library staff with tools and awareness, this interactive webinar explored how libraries can better serve neurodiverse patrons, such as those with autism, attention deficit hyperactivity disorder (ADHD), dyslexia, and other cognitive variations, while also supporting neurodiverse colleagues. Breakout rooms allowed participants to dive deeper into specific topics, including accessible program facilitation, supporting neurodiverse colleagues, and an “Ask Me Anything” space that encouraged open dialogue and learning.

Library staff everywhere are invited to watch the recorded webinar on YouTube and learn more about serving neurodiverse patrons and colleagues.

The collaboration between NASA@ My Library (led by the Space Science Institute), and NASA’s Neurodiversity Network (N3) (led by Sonoma State University), reflects a shared commitment to broadening participation in STEM (Science, Technology, Engineering, and Mathematics). NASA@ My Library works with public libraries nationwide to engage diverse communities in NASA science and discoveries. N3 focuses on empowering neurodiverse learners – particularly those in high school – with opportunities to engage with NASA science and explore potential STEM career pathways.

Participants left inspired, and the demand for more is clear: attendees and speakers alike expressed interest in continuing the conversation, requesting additional training, and expressing interest in organizing a future conference centered on neurodiversity and inclusion in libraries.

Youth Services Librarian and webinar panelist Molly Creveling shared, “This was such a great opportunity, and I’m extremely proud to have been able to contribute to it, I wish I was able to attend everyone’s break out room!” And participant Jason Wood expressed in the chat, “Really, really appreciate this webinar. This is one of those days I am extra proud to be a librarian. Thank you all.” Another enthusiast participant said, “This was the best webinar I’ve attended in years…more of this!”

Watch the recorded webinar.

As NASA continues to reach for the stars, it’s equally committed to ensuring that the journey is accessible to all – especially those whose unique ways of thinking and learning bring fresh perspectives to science, exploration, and discovery.

Software designed to give spacecraft more autonomy could support a future where swarms of satellites navigate and complete scientific objectives with limited human intervention.

Caleb Adams, Distributed Spacecraft Autonomy project manager, monitors testing alongside the test racks containing 100 spacecraft computers at NASA’s Ames Research Center in California’s Silicon Valley. The DSA project develops and demonstrates software to enhance multi-spacecraft mission adaptability, efficiently allocate tasks between spacecraft using ad-hoc networking, and enable human-swarm commanding of distributed space missions.

Astronauts living and working on the Moon and Mars will rely on satellites to provide services like navigation, weather, and communications relays. While managing complex missions, automating satellite communications will allow explorers to focus on critical tasks instead of manually operating satellites.  

Long duration space missions will require teaming between systems on Earth and other planets. Satellites orbiting the Moon, Mars, or other distant areas face communications delays with ground operators which could limit the efficiency of their missions.  

The solution lies within the Distributed Spacecraft Autonomy (DSA) project, led by NASA’s Ames Research Center in California’s Silicon Valley, which tests how shared autonomy across distributed spacecraft missions makes spacecraft swarms more capable of self-sufficient research and maintenance by making decisions and adapting to changes with less human intervention. 

Adding autonomy to satellites makes them capable of providing services without waiting for commands from ground operators. Distributing the autonomy across multiple satellites, operating like a swarm, gives the spacecraft a “shared brain” to accomplish goals they couldn’t achieve alone. 

The DSA software, built by NASA researchers, provides the swarm with a task list, and shares each spacecraft’s distinct perspective – what it can observe, what its priorities are – and integrates those perspectives into the best plan of action for the whole swarm. That plan is supported by decision trees and mathematical models that help the swarm decide what action to take after a command is completed, how to respond to a change, or address a problem. 

Sharing the Workload

The first in-space demonstration of DSA began onboard the Starling spacecraft swarm, a group of four small satellites, demonstrating various swarm technologies. Operating since July 2023, the Starling mission continues providing a testing and validation platform for autonomous swarm operations. The swarm first used DSA to optimize scientific observations, deciding what to observe without pre-programmed instructions. These autonomous observations led to measurements that could have been missed if an operator had to individually instruct each satellite. 

The Starling swarm measured the electron content of plasma between each spacecraft and GPS satellites to capture rapidly changing phenomena in Earth’s ionosphere – where Earth’s atmosphere meets space. The DSA software allowed the swarm to independently decide what to study and how to spread the workload across the four spacecraft. 

Because each Starling spacecraft operates as an independent member within the swarm, if one swarm member was unable to accomplish its work, the other three swarm members could react and complete the mission’s goals. 

The Starling 1.0 demonstration achieved several firsts, including the first fully distributed autonomous operation of multiple spacecraft, the first use of space-to-space communications to autonomously share status information between multiple spacecraft, the first demonstration of fully distributed reactive operations onboard multiple spacecraft, the first use of a general-purpose automated reasoning system onboard a spacecraft, and the first use of fully distributed automated planning onboard multiple spacecraft. These achievements laid the groundwork for Starling 1.5+, an ongoing continuation of the satellite swarm’s mission using DSA.

After DSA’s successful demonstration on Starling 1.0, the team began exploring additional opportunities to use the software to support satellite swarm health and efficiency. Continued testing of DSA on Starling’s extended mission included PLEXIL (Plan Execution Interchange Language), a NASA-developed programming language designed for reliable and flexible automation of complex spacecraft operations. 

Onboard Starling, the PLEXIL application demonstrated autonomous maintenance, allowing the swarm to manage normal spacecraft operations, correct issues, or distribute software updates across individual spacecraft.  

Enhanced autonomy makes swarm operation in deep space feasible – instead of requiring spacecraft to communicate back and forth between their distant location and Earth, which can take minutes or hours depending on distance, the PLEXIL-enabled DSA software gives the swarm the ability to make decisions collaboratively to optimize their mission and reduce workloads. 

Simulated Lunar Swarming 

To understand the scalability of DSA, the team used ground-based flight computers to simulate a lunar swarm of virtual small spacecraft. The computers simulated a swarm that provides position, navigation, and timing services on the Moon, similar to GPS services on Earth, which rely on a network of satellites to pinpoint locations. 

The DSA team ran nearly one hundred tests over two years, demonstrating swarms of different sizes at high and low lunar orbits. The lessons learned from those early tests laid the groundwork for additional scalability studies. The second round of testing, set to begin in 2026, will demonstrate even larger swarms, using flight computers that could later go into orbit with DSA software onboard. 

The Future of Spacecraft Swarms 

Orbital and simulated tests of DSA are a launchpad to increased use of distributed autonomy across spacecraft swarms. Developing and proving these technologies increases efficiency, decreases costs, and enhances NASA’s capabilities opening the door to autonomous spacecraft swarms supporting missions to the Moon, Mars, and beyond.

Astronauts living and working on the Moon and Mars will rely on satellites to provide services like navigation, weather, and communications relays. While managing complex missions, automating satellite communications will allow explorers to focus on critical tasks instead of manually operating satellites.  

Long duration space missions will require teaming between systems on Earth and other planets. Satellites orbiting the Moon, Mars, or other distant areas face communications delays with ground operators which could limit the efficiency of their missions.  

The solution lies within the Distributed Spacecraft Autonomy (DSA) project, led by NASA’s Ames Research Center in California’s Silicon Valley, which tests how shared autonomy across distributed spacecraft missions makes spacecraft swarms more capable of self-sufficient research and maintenance by making decisions and adapting to changes with less human intervention. 

Adding autonomy to satellites makes them capable of providing services without waiting for commands from ground operators. Distributing the autonomy across multiple satellites, operating like a swarm, gives the spacecraft a “shared brain” to accomplish goals they couldn’t achieve alone. 

The DSA software, built by NASA researchers, provides the swarm with a task list, and shares each spacecraft’s distinct perspective – what it can observe, what its priorities are – and integrates those perspectives into the best plan of action for the whole swarm. That plan is supported by decision trees and mathematical models that help the swarm decide what action to take after a command is completed, how to respond to a change, or address a problem. 

Sharing the Workload

The first in-space demonstration of DSA began onboard the Starling spacecraft swarm, a group of four small satellites, demonstrating various swarm technologies. Operating since July 2023, the Starling mission continues providing a testing and validation platform for autonomous swarm operations. The swarm first used DSA to optimize scientific observations, deciding what to observe without pre-programmed instructions. These autonomous observations led to measurements that could have been missed if an operator had to individually instruct each satellite. 

The Starling swarm measured the electron content of plasma between each spacecraft and GPS satellites to capture rapidly changing phenomena in Earth’s ionosphere – where Earth’s atmosphere meets space. The DSA software allowed the swarm to independently decide what to study and how to spread the workload across the four spacecraft. 

Because each Starling spacecraft operates as an independent member within the swarm, if one swarm member was unable to accomplish its work, the other three swarm members could react and complete the mission’s goals. 

The Starling 1.0 demonstration achieved several firsts, including the first fully distributed autonomous operation of multiple spacecraft, the first use of space-to-space communications to autonomously share status information between multiple spacecraft, the first demonstration of fully distributed reactive operations onboard multiple spacecraft, the first use of a general-purpose automated reasoning system onboard a spacecraft, and the first use of fully distributed automated planning onboard multiple spacecraft. These achievements laid the groundwork for Starling 1.5+, an ongoing continuation of the satellite swarm’s mission using DSA.

After DSA’s successful demonstration on Starling 1.0, the team began exploring additional opportunities to use the software to support satellite swarm health and efficiency. Continued testing of DSA on Starling’s extended mission included PLEXIL (Plan Execution Interchange Language), a NASA-developed programming language designed for reliable and flexible automation of complex spacecraft operations. 

Onboard Starling, the PLEXIL application demonstrated autonomous maintenance, allowing the swarm to manage normal spacecraft operations, correct issues, or distribute software updates across individual spacecraft.  

Enhanced autonomy makes swarm operation in deep space feasible – instead of requiring spacecraft to communicate back and forth between their distant location and Earth, which can take minutes or hours depending on distance, the PLEXIL-enabled DSA software gives the swarm the ability to make decisions collaboratively to optimize their mission and reduce workloads.

To understand the scalability of DSA, the team used ground-based flight computers to simulate a lunar swarm of virtual small spacecraft.

Science Observations Remain Paused for NASA’s NICER Telescope

Science operations by NASA’s NICER (Neutron star Interior Composition Explorer), an X-ray telescope on the International Space Station, remain paused as the team continues to evaluate the telescope’s systems after an issue developed with one of its motors. The motor is unable to move NICER beyond its current position side to side, and the telescope’s status has not changed since operations were halted June 17.

The primary goal is to move NICER into its stowed configuration in case it needs to accommodate space station activities, though the current placement does not pose a safety issue to the station or crew. The team currently does not have a timeframe for returning to science operations.

Photos taken by robotic cameras outside the station are helping eliminate external causes for the issue. Now the team is coordinating with space station personnel to perform troubleshooting maneuvers and determine potential causes within the payload.  

Since it began observing the X-ray universe in 2017, NICER has successfully demonstrated a form of deep space navigation that could be used for travel to Mars and beyond.

Designed for a prime mission of 18 months and now in its eighth year of operations, NICER has made groundbreaking measurements of neutron stars, which contain the densest matter in the universe that we can measure, and revolutionized our understanding of black holes, active galaxies, and other mysterious phenomena in our universe. Technology developed to test NICER before launch is being incorporated into prototype portable CT scanners, communications systems, and several other applications on Earth for the benefit of all.

NASA’s NICER Telescope Suspends Science Operations

NASA’s NICER (Neutron star Interior Composition Explorer), an X-ray telescope on the International Space Station, has paused observations due to a problem with one of the motors that drives its ability to track cosmic objects.

The NICER team paused operations June 17 when performance degradation in the motor began affecting science observations. Engineers are investigating the cause and potential solutions.

The telescope was installed near the space station’s starboard solar array in 2017. The NICER mission has successfully demonstrated a form of deep space navigation that could be used for travel to Mars and beyond. It has also made groundbreaking measurements of neutron stars, which contain the densest matter in the universe that we can measure, and revolutionized our understanding of black holes, active galaxies, and other mysterious phenomena in our universe.

Following Repair, NASA’s NICER Improves Daytime Measurements

A NASA X-ray telescope on the International Space Station called NICER, or Neutron star Interior Composition Explorer, has regained additional daytime observation capabilities thanks to repairs completed during a spacewalk and a reconfiguration of its detectors.

In May 2023, NICER developed a light leak in which unwanted sunlight began entering the instrument. Photos taken from inside the space station revealed several small areas of damage to the telescope’s thin thermal shields, which block sunlight while allowing X-rays through to the detectors. Nighttime observations were unaffected, and with operational adjustments, the NICER team was able to recover about 20% of station daytime observations.

In January, NASA astronaut Nick Hague installed nine patches to cover the largest areas of damage during a spacewalk. After resuming science operations, the NICER team determined the overall level of sunlight inside NICER had substantially reduced. Still, it experienced more visible-light interference than expected.

Close-up, high-resolution photos from the spacewalk allowed the team to see additional small holes and cracks in the thermal shields that were not previously visible. These accounted for the remaining sunlight intrusion.

After further analysis, the NICER team developed a novel approach to regaining additional daytime data collection.

Each X-ray that hits a NICER detector generates electrical charge that is sensed by a measurement/power unit (MPU). After so many hits, the detector resets — like emptying a cup before it overflows.

Sunlight can also create charge that accumulates in the detector, adding water to the metaphorical cup. There was so much sunlight entering NICER that the detectors were filling up with charge and resetting thousands of times for every X-ray detection. It overwhelmed the MPU’s ability to process the valid X-ray events.

Hague’s repair in January reduced the amount of sunlight entering NICER, which enabled the team to reconfigure the MPUs to ignore the sunlight-generated resets. After initial testing on the ground, the team updated one MPU before switching all seven. The changeover was completed March 12.

In combination with the patches, the reconfiguration has allowed NICER to return to collecting observations during more than 70% of station daytime, as the telescope continues to help us better understand the X-ray universe, including neutron stars, black holes, and other energetic phenomena. The team continues to look for more opportunities to improve NICER’s operations.

NASA’s NICER Continues Science Operations Post Repair

NASA crew aboard the International Space Station installed patches to the agency’s NICER (Neutron star Interior Composition Explorer) mission during a spacewalk on Jan. 16. NICER, an X-ray telescope perched near the station’s starboard solar array, resumed science operations later the same day.

The patches cover areas of NICER’s thermal shields where damage was discovered in May 2023. These thin filters block sunlight while allowing X-rays to pass through. After the discovery, the NICER team restricted their observations during the station’s daytime to avoid overwhelming the mission’s sensitive detectors. Nighttime observations were unaffected, and the team was able to continue collecting data for the science community to make groundbreaking measurements using the instrument’s full capabilities.

The repair went according to plan. Data since collected shows the detectors behind the patched areas are performing better than before during station night, and the overall level of sunlight inside NICER during the daytime is reduced substantially.

While NICER experiences less interference from sunlight than before, after analyzing initial data, the team has determined the telescope still experiences more interference than expected. The installed patches cover areas of known damage identified using astronomical observations and from photos taken by both external robotic cameras and astronauts inside the space station. Measurements collected since the repair and close-up, high-resolution photos obtained during the spacewalk are providing new information that may point the way toward further daytime data collection.

In the meantime, NICER continues operations with its full measurement capabilities during orbit night to enable further trailblazing discoveries in time domain and multimessenger astrophysics.

Sunlight ‘Leak’ Impacting NASA’s NICER Telescope, Science Continues

On Tuesday, May 22, NASA’s NICER (Neutron Star Interior Composition Explorer), an X-ray telescope on the International Space Station, developed a “light leak,” in which unwanted sunlight enters the instrument. While analyzing incoming data since then, the team identified an impact to daytime observations. Nighttime observations seem to be unaffected.

The team suspects that at least one of the thin thermal shields on NICER’s 56 X-ray Concentrators has been damaged, allowing sunlight to reach its sensitive detectors.

To mitigate the effects on measurements, the NICER team has limited daytime observations to objects far away from the Sun’s position in the sky. The team has also updated commands to NICER that automatically lower its sensitivity during the orbital day to reduce the effects from sunlight contamination. The team is evaluating these changes and assessing additional measures to reduce the impact on science observations.

To date, more than 300 scientific papers have used NICER observations, and the team is confident that NICER will continue to produce world-class science.
