Preparations for Next Moonwalk Simulations Underway (and Underwater) Ocean currents swirl around North America (center left) and Greenland (upper right) in this data visualization created using NASA’s ECCO model. Advanced computing is helping oceanographers decipher hot spots of phytoplankton growth.NASA’s Scientific Visualization StudioAs Greenland’s ice retreats, it’s fueling tiny ocean organisms. To test why, scientists turned to a computer model out of JPL and MIT that’s been called a laboratory in itself.
Runoff from Greenland’s ice sheet is kicking nutrients up from the ocean depths and boosting phytoplankton growth, a new NASA-supported study has found. Reporting in Nature Communications: Earth & Environment, the scientists used state-of-the art-computing to simulate marine life and physics colliding in one turbulent fjord. Oceanographers are keen to understand what drives the tiny plantlike organisms, which take up carbon dioxide and power the world’s fisheries.
Greenland’s mile-thick ice sheet is shedding some 293 billion tons (266 billion metric tons) of ice per year. During peak summer melt, more than 300,000 gallons (1,200 cubic meters) of fresh water drain into the sea every second from beneath Jakobshavn Glacier, also known as Sermeq Kujalleq,the most active glacier on the ice sheet. The waters meet and tumble hundreds of feet below the surface.
Teal-colored phytoplankton bloom off the Greenland coast in this satellite image captured in June 2024 by NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission.NASAThe meltwater plume is fresh and more buoyant than the surrounding saltwater. As it rises, scientists have hypothesized, it may be delivering nutrients like iron and nitrate — a key ingredient in fertilizer — to phytoplankton floating at the surface.
Researchers track these microscopic organisms because, though smaller by far than a pinhead, they’re titans of the ocean food web. Inhabiting every ocean from the tropics to the polar regions, they nourish krill and other grazers that, in turn, support larger animals, including fish and whales.
Previous work using NASA satellite data found that the rate of phytoplankton growth in Arctic waters surged 57% between 1998 and 2018 alone. An infusion of nitrate from the depths would be especially pivotal to Greenland’s phytoplankton in summer, after most nutrients been consumed by prior spring blooms. But the hypothesis has been hard to test along the coast, where the remote terrain and icebergs as big as city blocks complicate long-term observations.
“We were faced with this classic problem of trying to understand a system that is so remote and buried beneath ice,” said Dustin Carroll, an oceanographer at San José State University who is also affiliated with NASA’s Jet Propulsion Laboratory in Southern California. “We needed a gem of a computer model to help.”
Sea of DataTo re-create what was happening in the waters around Greenland’s most active glacier, the team harnessed a model of the ocean developed at JPL and the Massachusetts Institute of Technology in Cambridge. The model ingests nearly all available ocean measurements collected by sea- and satellite-based instruments over the past three decades. That amounts to billions of data points, from water temperature and salinity to pressure at the seafloor. The model is called Estimating the Circulation and Climate of the Ocean-Darwin (ECCO-Darwin for short).
Simulating “biology, chemistry, and physics coming together” in even one pocket along Greenland’s 27,000 miles (43,000 kilometers) of coastline is a massive math problem, noted lead author Michael Wood, a computational oceanographer at San José State University. To break it down, he said the team built a “model within a model within a model” to zoom in on the details of the fjord at the foot of the glacier.
Using supercomputers at NASA’s Ames Research Center in Silicon Valley, they calculated that deepwater nutrients buoyed upward by glacial runoff would be sufficient to boost summertime phytoplankton growth by 15 to 40% in the study area.
More Changes in StoreCould increased phytoplankton be a boon for Greenland’s marine animals and fisheries? Carroll said that untangling impacts to the ecosystem will take time. Melt on the Greenland ice sheet is projected to accelerate in coming decades, affecting everything from sea level and land vegetation to the saltiness of coastal waters.
“We reconstructed what’s happening in one key system, but there’s more than 250 such glaciers around Greenland,” Carroll said. He noted that the team plans to extend their simulations to the whole Greenland coast and beyond.
Some changes appear to be impacting the carbon cycle both positively and negatively: The team calculated how runoff from the glacier alters the temperature and chemistry of seawater in the fjord, making it less able to dissolve carbon dioxide. That loss is canceled out, however, by the bigger blooms of phytoplankton taking up more carbon dioxide from the air as they photosynthesize.
Wood added: “We didn’t build these tools for one specific application. Our approach is applicable to any region, from the Texas Gulf to Alaska. Like a Swiss Army knife, we can apply it to lots of different scenarios.”

NASA’s Perseverance Rover Captures Mars Vista As Clear As Day
‘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.”
Buoyant BoulderOne 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” Wilmore Retires
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.”

Curiosity Looks Back Toward Its Landing Site
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. Read more about the detective work Curiosity is doing on Mars.

Mississippi Attorney Serves NASA and the Nation
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-CaltechWritten 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 Selects Six Companies to Provide Orbital Transfer Vehicle Studies
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’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 NASAThe 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 NASANASA 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 NASANASA 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 NASAThe 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.

NASAIn 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 NASAA 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 NASAIndividual 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 NASANASA 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 NASAAstronaut 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 NASANASA 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 NASANASA 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 NASANASA 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.
Catching a corona NASA/KASI/INAF/CODEXThis 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 NASAAstronaut 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 NASANASA 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 NASASpaceflight 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 LibrariesOn 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!”
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.

What is NASA’s Distributed Spacecraft Autonomy?
Software designed to give spacecraft more autonomy could support a future where swarms of satellites navigate and complete scientific objectives with limited human intervention.

Credit: NASA/Brandon Torres NavarreteAstronauts 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 WorkloadThe 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.
Advanced testing of DSA onboard Starling shows that distributed autonomy in spacecraft swarms can improve efficiencies while reducing the workload on human operators.Credit: NASA/Daniel Rutter A Helping Hand in OrbitAfter 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 SwarmingTo 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 SwarmsOrbital 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.

Curiosity Blog, Sols 4616-4617: Standing Tall on the Ridge NASA’s Mars rover Curiosity acquired this image, showing the impressive landscape it is currently navigating. The rover is standing tall on the ridge, its shadow casting forward, and Mount Sharp towers over the scene in the distance. Curiosity captured this image with its Front Hazard Avoidance Camera (Front Hazcam) on July 30, 2025 — Sol 4614, or Martian day 4,614 of the Mars Science Laboratory mission — at 02:24:02 UTC.

Earth planning date: Wednesday, July 30, 2025
The day started with a little celebration of NISAR, a new Earth observation satellite that made it successfully into orbit a few hours before our planning started. We joined in by saying “GO NISAR, NASA, JPL, and ISRO” (the Indian Space Research Organisation, NASA’s mission partner, which launched NISAR). Learn more at the NISAR mission hub. Although our team studies Mars, Earth is a planet, too, and we are very happy for our colleagues’ successful launch!
On Mars, it’s still winter and the topic of every planning is how to maximize the science we can do given the increased power needs for heating our rover at this time of the year. Curiosity is parked on top of the main ridge, nicknamed the “autobahn.” It turned out to be not as smooth as its terrestrial namesake, as you can see in the image above. To arrive at this parking position, our rover drivers decided to take a small detour down into a flatter area and back up onto the ridge for safe off-road driving. The rover’s parking position allows for beautiful views around us, laying out the land of hollows and ridges perfectly to plan our next steps and to admire Mount Sharp in the distance.
Standing tall on the ridge, we got several investigations of the ridge-forming materials into today’s plan. APXS, MAHLI, and ChemCam are all teaming up to investigate the target “El Salto.” This is a target that could get us a glimpse into what formed the central line that is running along the big ridge. If you look closely at the images there are subtle differences in color and texture, and we are all curious whether that translates to chemical differences, too.
Of course, it’s not all about chemistry. Mastcam is busy documenting a small mound, and its context with veins and the hollow surrounding it, at the target “Llullaillaco.” The target “Cementerio De Tortugas” will capture sand ripples within a trough area, there is an extension of the workspace imaging in the plan for more context of today’s observations, and finally the ridge intersection is of interest at the target “Villa Abecia.” Of course, Mastcam didn’t forget the documentation of the ChemCam target “El Salto” and the AEGIS target from the last plan. Speaking of ChemCam: It’s using its imaging capabilities to document the side of the ridge to give finer details of the sedimentary structures of the target “Llullaillaco.”
Atmospheric observations are also of highest interest at this time of the day. We continue our atmospheric monitoring by looking for dust devils as well as up toward the clouds in a joint observation with the CASSIS instrument, which is aboard the European Space Agency’s Trace Gas Orbiter. In addition, Curiosity continues to monitor wind and temperature throughout the plan, and the DAN (dynamic albedo of neutrons) instrument observes the rocks underneath the rover for their water content.
After completing the observations at the current parking location, Curiosity will be driving off the ridge again, but this time to stay within the hollow, so we can make observations of the material that forms those hollows. Let’s see if we can find any chemical differences between those materials that might explain why one is standing up tall and the other one is weathering out. If you want to get a better impression of what I am talking about when I say ridges and troughs, have a look at this recent navigation camera mosaic.

STEM Educators Are Bringing Hands-On NASA Science into Virginia ClassroomsProfessional learning experiences are integral to the enhancement of classroom instruction. Teachers, at the forefront of Science, Technology, Engineering, & Mathematics (STEM) education, play a key role in the advancement of STEM learning ecosystems and citizen science.
On June 24-25, 2025 – despite a major east coast heat wave – twenty-four educators from eight school districts in the Hampton Roads region of southeastern Virginia (Newport News, Hampton City, Virginia Beach City, Isle of Wight County, Poquoson City, Norfolk, York County, and Suffolk Public Schools) converged at the National Institute of Aerospace (NIA) in Hampton, VA for a professional development workshop led by experts from NASA Langley Research Center and the NASA Science Activation program’s NIA-led NASA eClips team. Developed in collaboration with another NASA Science Activation team, GLOBE (Global Learning and Observations to Benefit the Environment) Mission Earth, and with support from the Coastal Virginia STEM Hub (COVA STEM) – a “STEM learning ecosystem targeting pre-K to adult residents in Coastal Virginia” – this two-day training, also provided comprehensive resources, including lesson plans, pacing guides, classroom activities, and books, all designed for integration into Hampton Roads classrooms.
The NASA Langley team led workshop participants through a training about GLOBE, a program dedicated to advancing Earth System science through data collected by volunteer members of the public, also known as ‘citizen scientists’. GLOBE invites educators, students, and members of the public worldwide (regardless of citizenship) to collect and submit cloud, surface temperature, and land cover observations using the GLOBE Observer app – a real-time data collection tool available right on their smartphones. These observations are then used to help address scientific questions at local, regional, and global scales. Through this training, the educators participated in K-20 classroom-friendly sample lessons, hands-on activities, and exploring the GLOBE Observer app, ultimately qualifying them as GLOBE Certified Educators. Earth System science lessons, activities, and information on how to download the GLOBE Observer citizen science app are available on the GLOBE website. Similarly, NASA eClips, which focuses on increasing STEM literacy in K-12 students, provided educators with free, valuable, standards-based classroom resources such as educator guides, informational videos, engineering design packets, and hands-on activities, which are available to educators and students alike on the NASA eClips’ website. Throughout the training, educators collaborated in grade-level groups, brainstorming new ways to integrate these standards-based NASA science resources.
One educator envisioned incorporating GLOBE’s cloud resources and supportive NASA eClips videos into her energy budget unit. Others explored modifying a heat-lamp experiment to include humidity and heat capacity. One teacher enthusiastically noted in response to a GLOBE urban heat island lesson plan, “The hands-on elements are going to be really great deliverables!” The creative energy and passion for education were palpable.
The dedication of both NIA and NASA Langley to education and local community support was evident. This professional learning experience offered educators immediately-applicable classroom activities and fostered connections among NASA science, NASA eClips, the GLOBE Program, and fellow educators across district lines. One educator highlighted the value of these networking opportunities, stating, “I do love that we’re able to collaborate with our colleagues so we can plan for our future units during the school year”. Another participant commented, “This is a great program…I am going to start embedding [this] in our curriculum.”

NASA’s Lunar Trailblazer Moon Mission Ends
The small satellite was to map lunar water, but operators lost contact with the spacecraft the day after launch and were unable to recover the mission.
NASA’s Lunar Trailblazer ended its mission to the Moon on July 31. Despite extensive efforts, mission operators were unable to establish two-way communications after losing contact with the spacecraft the day following its Feb. 26 launch.
The mission aimed to produce high-resolution maps of water on the Moon’s surface and determine what form the water is in, how much is there, and how it changes over time. The maps would have supported future robotic and human exploration of the Moon as well as commercial interests while also contributing to the understanding of water cycles on airless bodies throughout the solar system.
Lunar Trailblazer shared a ride on the second Intuitive Machines robotic lunar lander mission, IM-2, which lifted off at 7:16 p.m. EST on Feb. 26 aboard a SpaceX Falcon 9 rocket from the agency’s Kennedy Space Center in Florida. The small satellite separated as planned from the rocket about 48 minutes after launch to begin its flight to the Moon. Mission operators at Caltech’s IPAC in Pasadena established communications with the small spacecraft at 8:13 p.m. EST. Contact was lost the next day.
Without two-way communications, the team was unable to fully diagnose the spacecraft or perform the thruster operations needed to keep Lunar Trailblazer on its flight path.
“At NASA, we undertake high-risk, high-reward missions like Lunar Trailblazer to find revolutionary ways of doing new science,” said Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “While it was not the outcome we had hoped for, mission experiences like Lunar Trailblazer help us to learn and reduce the risk for future, low-cost small satellites to do innovative science as we prepare for a sustained human presence on the Moon. Thank you to the Lunar Trailblazer team for their dedication in working on and learning from this mission through to the end.”
The limited data the mission team had received from Lunar Trailblazer indicated that the spacecraft’s solar arrays were not properly oriented toward the Sun, which caused its batteries to become depleted.
For several months, collaborating organizations around the world — many of which volunteered their assistance — listened for the spacecraft’s radio signal and tracked its position. Ground radar and optical observations indicated that Lunar Trailblazer was in a slow spin as it headed farther into deep space.
“As Lunar Trailblazer drifted far beyond the Moon, our models showed that the solar panels might receive more sunlight, perhaps charging the spacecraft’s batteries to a point it could turn on its radio,” said Andrew Klesh, Lunar Trailblazer’s project systems engineer at NASA’s Jet Propulsion Laboratory in Southern California. “The global community’s support helped us better understand the spacecraft’s spin, pointing, and trajectory. In space exploration, collaboration is critical — this gave us the best chance to try to regain contact.”
However, as time passed, Lunar Trailblazer became too distant to recover as its telecommunications signals would have been too weak for the mission to receive telemetry and to command.
Technological LegacyThe small satellite’s High-resolution Volatiles and Minerals Moon Mapper (HVM3) imaging spectrometer was built by JPL to detect and map the locations of water and minerals. The mission’s Lunar Thermal Mapper (LTM) instrument was built by the University of Oxford in the United Kingdom and funded by the UK Space Agency to gather temperature data and determine the composition of silicate rocks and soils to improve understanding of why water content varies over time.
“We’re immensely disappointed that our spacecraft didn’t get to the Moon, but the two science instruments we developed, like the teams we brought together, are world class,” said Bethany Ehlmann, the mission’s principal investigator at Caltech. “This collective knowledge and the technology developed will cross-pollinate to other projects as the planetary science community continues work to better understand the Moon’s water.”
Some of that technology will live on in the JPL-built Ultra Compact Imaging Spectrometer for the Moon (UCIS-Moon) instrument that NASA recently selected for a future orbital flight opportunity. The instrument, which has has an identical spectrometer design as HVM3, will provide the Moon’s highest spatial resolution data of surface lunar water and minerals.
More About Lunar TrailblazerLunar Trailblazer was selected by NASA’s SIMPLEx (Small Innovative Missions for Planetary Exploration) competition, which provides opportunities for low-cost science spacecraft to ride-share with selected primary missions. To maintain the lower overall cost, SIMPLEx missions have a higher risk posture and less-stringent requirements for oversight and management. This higher risk acceptance bolsters NASA’s portfolio of targeted science missions designed to test pioneering mission approaches.
Caltech, which manages JPL for NASA, led Lunar Trailblazer’s science investigation, and Caltech’s IPAC led mission operations, which included planning, scheduling, and sequencing of all spacecraft activities. Along with managing Lunar Trailblazer, NASA JPL provided system engineering, mission assurance, the HVM3 instrument, and mission design and navigation. Lockheed Martin Space provided the spacecraft, integrated the flight system, and supported operations under contract with Caltech. The University of Oxford developed and provided the LTM instrument, funded by the UK Space Agency. Lunar Trailblazer, a project of NASA’s Lunar Discovery and Exploration Program, was managed by NASA’s Planetary Missions Program Office at Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate in Washington.

Marking 13 Years on Mars, NASA’s Curiosity Picks Up New Skills
5 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) This view of tracks trailing NASA’s Curiosity was captured July 26, 2025, as the rover simultaneously relayed data to a Mars orbiter. Combining tasks like this more efficiently uses energy generated by Curiosity’s nuclear power source, seen here lined with rows of white fins at the back of the rover.NASA/JPL-Caltech This is the same view of Curiosity’s July 25 mosaic, with labels indicating some key parts of the rover involved in recent efficiency improvements, plus a few prominent locations in the distance.NASA/JPL-CaltechNew capabilities allow the rover to do science with less energy from its batteries.
Thirteen years since Curiosity landed on Mars, engineers are finding ways to make the NASA rover even more productive. The six-wheeled robot has been given more autonomy and the ability to multitask — improvements designed to make the most of Curiosity’s energy source, a multi-mission radioisotope thermoelectric generator (MMRTG). Increased efficiency means the rover has ample power as it continues to decipher how the ancient Martian climate changed, transforming a world of lakes and rivers into the chilly desert it is today.
Explore the view Curiosity captured while multitaskingCuriosity recently rolled into a region filled with boxwork formations. These hardened ridges are believed to have been created by underground water billions of years ago. Stretching for miles on this part of Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain, the formations might 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.
NASA’s Curiosity viewed this rock shaped like a piece of coral on July 24, 2025, the 4,608th Martian day of the mission. The rover has found many rocks that — like this one — were formed by minerals deposited by ancient water flows combined with billions of years of sandblasting by wind.NASA/JPL-Caltech/MSSSCarrying out this detective work involves a lot of energy. Besides driving and extending a robotic arm to study rocks and cliffsides, Curiosity has a radio, cameras, and 10 science instruments that all need power. So do the multiple heaters that keep electronics, mechanical parts, and instruments operating at their best. Past missions like the Spirit and Opportunity rovers and the InSight lander relied on solar panels to recharge their batteries, but that technology always runs the risk of not receiving enough sunlight to provide power.
Instead, Curiosity and its younger sibling Perseverance each use their MMRTG nuclear power source, which relies on decaying plutonium pellets to create energy and recharge the rover’s batteries. Providing ample power for the rovers’ many science instruments, MMRTGs are known for their longevity (the twin Voyager spacecraft have relied on RTGs since 1977). But as the plutonium decays over time, it takes longer to recharge Curiosity’s batteries, leaving less energy for science each day.
The team carefully manages the rover’s daily power budget, factoring in every device that draws on the batteries. While these components were all tested extensively before launch, they are part of complex systems that reveal their quirks only after years in the extreme Martian environment. Dust, radiation, and sharp temperature swings bring out edge cases that engineers couldn’t have expected.
“We were more like cautious parents earlier in the mission,” said Reidar Larsen of NASA’s Jet Propulsion Laboratory in Southern California, which built and operates the rover. Larsen led a group of engineers who developed the new capabilities. “It’s as if our teenage rover is maturing, and we’re trusting it to take on more responsibility. As a kid, you might do one thing at a time, but as you become an adult, you learn to multitask.”
More Efficient ScienceGenerally, JPL engineers send Curiosity a list of tasks to complete one by one before the rover ends its day with a nap to recharge. In 2021, the team began studying whether two or three rover tasks could be safely combined, reducing the amount of time Curiosity is active.
For example, Curiosity’s radio regularly sends data and images to a passing orbiter, which relays them to Earth. Could the rover talk to an orbiter while driving, moving its robotic arm, or snapping images? Consolidating tasks could shorten each day’s plan, requiring less time with heaters on and instruments in a ready-to-use state, reducing the energy used. Testing showed Curiosity safely could, and all of these have now been successfully demonstrated on Mars.
Another trick involves letting Curiosity decide to nap if it finishes its tasks early. Engineers always pad their estimates for how long a day’s activity will take just in case hiccups arise. Now, if Curiosity completes those activities ahead of the time allotted, it will go to sleep early.
By letting the rover manage when it naps, there is less recharging to do before the next day’s plan. Even actions that trim just 10 or 20 minutes from a single activity add up over the long haul, maximizing the life of the MMRTG for more science and exploration down the road.
Miles to GoIn fact, the team has been implementing other new capabilities on Curiosity for years. Several mechanical issues required a rework of how the robotic arm’s rock-pulverizing drill collects samples, and driving capabilities have been enhanced with software updates. When a color filter wheel stopped turning on one of the two cameras mounted on Mastcam, Curiosity’s swiveling “head,” the team developed a workaround allowing them to capture the same beautiful panoramas.
JPL also developed an algorithm to reduce wear on Curiosity’s rock-battered wheels. And while engineers closely monitor any new damage, they aren’t worried: After 22 miles (35 kilometers) and extensive research, it’s clear that, despite some punctures, the wheels have years’ worth of travel in them. (And in a worst-case scenario, Curiosity could remove the damaged part of the wheel’s “tread” and still drive on the remaining part.)
Together, these measures are doing their job to keep Curiosity as busy as ever.

Perseids Meteor Shower
In this 30 second exposure photograph, a meteor streaks across the sky during the annual Perseid and Alpha Capricornids meteor showers, Sunday, Aug. 3, 2025, in Spruce Knob, West Virginia.
The Perseids meteor shower, which peaks in mid-August, is considered the best of the year. With swift and bright meteors, Perseids frequently leave long “wakes” of light and color behind them as they streak through Earth’s atmosphere. The Perseids are one of the most plentiful showers with about 50 to 100 meteors seen per hour.
This year, visibility will be hampered by an 84%-full Moon on the peak night. A few bright meteors may still be seen in the pre-dawn hours, but viewing conditions are not ideal.

NASA’s Artemis Crew Trains in Moonbound Orion Ahead of Mission
The first crew slated to fly in NASA’s Orion spacecraft during the Artemis II mission around the Moon early next year entered their spacecraft for a multi-day training at the agency’s Kennedy Space Center in Florida. Crew donned their spacesuits July 31 and boarded Orion to train and experience some of the conditions they can expect on their mission.
NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen participated in a suited crew test and crew equipment interface test, performing launch day and simulated orbital activities inside Orion.

“In about six months, Artemis II astronauts will journey around the Moon for the first time in 53 years,” Duffy said. “America rallied behind Apollo because it represented the best of us – now it’s Artemis’ turn. They’re not just carrying a flag – they’re carrying the pride, power, and promise of the United States of America.”
With Orion powered on, the suited crew test was a close representation of what the crew can expect on launch day. The crew began the day by suiting up inside the spaceport’s Multi-Operation Support Building, donning their Orion crew survival system spacesuits, boarding the zero-emission crew transportation vehicles, and entering Orion, which is currently inside the Multi-Payload Processing Facility, where engineers have loaded its propellants over the course of several weeks.
Once in Orion, the crew performed several launch day activities, including communications checkouts and suit leak checks. For the first time, the crew was connected to the spacecraft and its communications and life control systems, and all umbilicals were connected while the spacecraft operated on full power.
Teams simulated several different ground and flight conditions to give the crew more experience managing them in real time. Some of the activities simulated scenarios where the crew was challenged to address potential issues while in space such as leaks and failure of the air revitalization system fan, which is needed to provide oxygen and remove carbon dioxide from the cabin. Getting this hands-on experience and learning how to act fast to overcome potential challenges during flight helps ensure the crew is ready for any scenario.
The test provides astronauts the ability to train on the actual hardware they will use during flight, allowing them and support teams the opportunity to familiarize themselves with the equipment in configurations very close to what will be experienced during flight. It also allows teams to verify compatibility between the equipment and systems with flight controller procedures, so they can make any final adjustments ahead of launch.

“It signifies the immense amount of work that our operations and development teams put into making sure we are ready for launch.” Quinn said. “They have meticulously planned each operation, timing them to perfection – and now we put it to the test.”
Exchanging their spacesuits for cleanroom garments for the crew equipment interface test, and with the spacecraft powered off, the crew also performed many of the activities they are likely to do in flight and conducted additional equipment checks. The crew practiced removing and stowing the foot pans on the pilot and commander seats, which will allow them to have more open space in the cabin after launch. They also accessed the stowage lockers and familiarized themselves with cameras, associated cables and mounts, and the environmental control and life support system hardware.
In addition to getting practical experience with the actual hardware they’ll use in space, they also prepared for life in deep space, reviewing cabin labels, sleep arrangements and checklists, and the hygiene bay.
Through the Artemis campaign, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars – for the benefit of all.
Mark Cavanaugh: Integrating Safety into the Orion Spacecraft
Before astronauts venture around the Moon on Artemis II, the agency’s first crewed mission to the Moon since Apollo, Mark Cavanaugh is helping make sure the Orion spacecraft is safe and space-ready for the journey ahead.
As an Orion integration lead at NASA’s Johnson Space Center in Houston, he ensures the spacecraft’s critical systems— in both the U.S.-built crew module and European-built service module—come together safely and seamlessly.

He oversees the technical integration of the European Service Module, which provides power, propulsion, and life support to Orion during Artemis missions to the Moon. His work includes aligning and verifying essential systems to keeping the crew alive, including oxygen, nitrogen, water storage, temperature regulation, and spacecraft structures.
In addition to his integration work, Cavanaugh is an Orion Mission Evaluation Room (MER) manager. The MER is the engineering nerve center during Artemis flights, responsible for real-time monitoring of the Orion spacecraft and real-time decision-making. From prelaunch to splashdown, Cavanaugh will lead a team of engineers who track vehicle health and status, troubleshoot anomalies, and communicate directly with the flight director to ensure the mission remains safe and on track.

That passion only deepened after a fifth-grade trip from Philadelphia to Houston with his grandfather. “My dream of working at NASA Johnson started when I visited the center for the first time,” he said. “Going from being a fifth grader riding the tram on the tour to contributing to the great work done at Johnson has been truly incredible.”
Turning that childhood dream into reality did not come with a straight path. Cavanaugh graduated from Pennsylvania State University in 2011, the same year NASA’s Space Shuttle Program ended. With jobs in the space industry in short supply, he took a position with Boeing in Houston, working on the International Space Station’s Passive Thermal Control System. He later supported thermal teams for the Artemis Moon rocket called the Space Launch System, and the Starliner spacecraft that flew astronauts Butch Wilmore and Suni Williams during their Boeing Crew Flight Test mission, before a mentor flagged a NASA job posting that turned out to be the perfect fit.
He joined NASA as the deputy system manager for Orion’s Passive Thermal Control System, eventually stepping into his current leadership role on the broader Orion integration team. “I’ve been very lucky to work with some of the best and most supportive teammates you can imagine,” he said.

That mindset helps keep things constructive and prevents misunderstandings.”
He also emphasizes the importance of creative problem-solving. “For me, overcoming technical challenges comes down to seeking different perspectives, questioning assumptions, and not being afraid to try something new—even if it sounds a little ridiculous at first.”

When he is not on the track or in the control room, Cavanaugh gives back through student outreach. “The thing I always stress when I talk to students is that nothing is impossible,” he said. “I never thought I’d get to work in the space industry, let alone at NASA. But I stayed open to opportunities—even the ones that didn’t match what I originally imagined for myself.”
