Curiosity Blog, Sols 4604-4606: Taking a Deep Breath of Martian Air

Written by Lauren Edgar, Planetary Geologist at USGS Astrogeology Science Center

Earth planning date: Friday, July 18, 2025

Curiosity has started to investigate the main exposure of the boxwork structures! What was once a distant target is now on our doorstep, and Curiosity is beginning to explore the ridges and hollows that make up this terrain, to better understand their chemistry, morphology, and sedimentary structures.

I was on shift as Long Term Planner during this three-sol weekend plan, and the team put together a very full set of activities to thoroughly investigate this site — from the sky to the sand. The plan starts with Navcam and Mastcam observations to assess the amount of dust in the atmosphere, followed by a large Mastcam mosaic to characterize the resistant ridge on which the rover is parked. ChemCam will also acquire a LIBS observation on a target named “Vicuna” to assess the chemistry of a well-exposed vein. The team chose this parking location to characterize the chemistry and textures of this topographic ridge (to compare with topographic lows), so the next part of the plan involves contact science using APXS and MAHLI to look at different parts of the nodular bedrock in our workspace, at targets named “Totoral” and “Sillar.” There’s also a MAHLI observation of the same vein that ChemCam targeted.

The second sol involves more Mastcam imaging to look at different parts of this prominent ridge, along with a ChemCam LIBS observation on top of the ridge, and a ChemCam RMI mosaic to document the sedimentary structures in a distant boxwork feature. Navcam will also be used to look for dust devils. Then Curiosity will take a short drive of about 5 meters (about 16 feet) to explore the adjacent hollow (seen as the low point in the foreground of the above Navcam image). After the drive we’ll take more images for context, and to prepare for targeting in Monday’s plan.

After all of this work it’s time to pause and take a deep breath… of Martian atmosphere. The weekend plan involves an exciting campaign to look for variations in atmospheric chemistry between night and day. So Curiosity will take an overnight APXS atmospheric observation at the same time that two instruments within SAM assess its chemical and isotopic abundance.

On the third sol Curiosity will acquire a ChemCam passive sky observation, leading to a great set of atmospheric data. These measurements will be compared to even more atmospheric activities in Monday’s plan to get the full picture. As you can imagine, this plan requires a lot of power, but it’s worth it for all of the exciting science that we can accomplish here.

The road ahead has many highs and lows (literally), but I can’t wait to see what Curiosity will accomplish. The distant buttes remind us that there’s so much more to explore, and I look forward to continuing to see where Curiosity will take us.

NASA Tests New Heat Source Fuel for Deep Space Exploration

Tue, 07/22/2025 - 8:03am

To explore the unknown in deep space, millions of miles away from Earth, it’s crucial for spacecraft to have ample power. NASA’s radioisotope power systems (RPS) are a viable option for these missions and have been used for over 60 years, including for the agency’s Voyager spacecraft and Perseverance Mars rover. These nuclear batteries provide long-term electrical power for spacecraft and science instruments using heat produced by the natural radioactive decay of radioisotopes. Now, NASA is testing a new type of RPS heat source fuel that could become an additional option for future long-duration journeys to extreme environments.

Historically, the radioisotope plutonium-238 (plutonium oxide) has been NASA’s RPS heat source fuel of choice, but americium-241 has been a source of interest for the past two decades in Europe. In January, the Thermal Energy Conversion Branch at NASA’s Glenn Research Center in Cleveland and the University of Leicester, based in the United Kingdom, partnered through an agreement to put this new option to the test.

One method to generate electricity from radioisotope heat sources is the free-piston Stirling convertor. This is a heat engine that converts thermal energy into electrical energy. However, instead of a crankshaft to extract power, pistons float freely within the engine. It could operate for decades continuously without wear, as it does not have piston rings or rotating bearings that will eventually wear out. Thus, a Stirling convertor could generate more energy, allowing more time for exploration in deep space. Researchers from the University of Leicester — who have been leaders in the development of americium RPS and heater units for more than 15 years — and NASA worked to test the capabilities of a Stirling generator testbed powered by two electrically heated americium-241 heat source simulators.

“The concept started as just a design, and we took it all the way to the prototype level: something close to a flight version of the generator,” said Salvatore Oriti, mechanical engineer at Glenn. “The more impressive part is how quickly and inexpensively we got it done, only made possible by a great synergy between the NASA and University of Leicester teams. We were on the same wavelength and shared the same mindset.”

The university provided the heat source simulators and generator housing. The heat source simulator is the exact size and shape of their real americium-241 heat source, but it uses embedded electric heaters to create an equivalent amount of heat to simulate the decay of americium fuel and therefore drive generator operation. The Stirling Research Lab at Glenn provided the test station, Stirling convertor hardware, and support equipment.

“A particular highlight of this (testbed) design is that it is capable of withstanding a failed Stirling convertor without a loss of electrical power,” said Hannah Sargeant, research fellow at the University of Leicester. “This feature was demonstrated successfully in the test campaign and highlights the robustness and reliability of an Americium-Radioisotope Stirling Generator for potential future spaceflight missions, including long-duration missions that could operate for many decades.”

The test proved the viability of an americium-fueled Stirling RPS, and performance and efficiency targets were successfully met. As for what’s next, the Glenn team is pursuing the next version of the testbed that will be lower mass, higher fidelity, and undergo further environmental testing.

“I was very pleased with how smoothly everything went,” Oriti said of the test results. “Usually in my experience, you don’t accomplish everything you set out to, but we did that and more. We plan to continue that level of success in the future.”

NASA Shares How to Save Camera 370-Million-Miles Away Near Jupiter

Mon, 07/21/2025 - 1:54pm

5 min read

Preparations for Next Moonwalk Simulations Underway (and Underwater) The north polar region of Jupiter’s volcanic moon Io was captured by the JunoCam imager aboard NASA’s Juno during the spacecraft’s 57th close pass of the gas giant on Dec. 30, 2023. A technique called annealing was used to help repair radiation damage to the camera in time to capture this image. Image data: NASA/JPL-Caltech/SwRI/MSSS Image processing by Gerald Eichstädt

An experimental technique rescued a camera aboard the agency’s Juno spacecraft, offering lessons that will benefit other space systems that experience high radiation.

The mission team of NASA’s Jupiter-orbiting Juno spacecraft executed a deep-space move in December 2023 to repair its JunoCam imager to capture photos of the Jovian moon Io. Results from the long-distance save were presented during a technical session on July 16 at the Institute of Electrical and Electronics Engineers Nuclear & Space Radiation Effects Conference in Nashville.

JunoCam is a color, visible-light camera. The optical unit for the camera is located outside a titanium-walled radiation vault, which protects sensitive electronic components for many of Juno’s engineering and science instruments.

This is a challenging location because Juno’s travels carry it through the most intense planetary radiation fields in the solar system. While mission designers were confident JunoCam could operate through the first eight orbits of Jupiter, no one knew how long the instrument would last after that.

Throughout Juno’s first 34 orbits (its prime mission), JunoCam operated normally, returning images the team routinely incorporated into the mission’s science papers. Then, during its 47th orbit, the imager began showing hints of radiation damage. By orbit 56, nearly all the images were corrupted.

The graininess and horizontal lines seen in this JunoCam image show evidence that the camera aboard NASA’s Juno mission suffered radiation damage. The image, which captures one of the circumpolar cyclones on Jupiter’s north pole, was taken Nov. 22, 2023. NASA/JPL-Caltech/SwRI/MSSS Long Distance Microscopic Repair

While the team knew the issue may be tied to radiation, pinpointing what, specifically, was damaged within JunoCam was difficult from hundreds of millions of miles away. Clues pointed to a damaged voltage regulator that is vital to JunoCam’s power supply. With few options for recovery, the team turned to a process called annealing, where a material is heated for a specified period before slowly cooling. Although the process is not well understood, the idea is that the heating can reduce defects in the material.

“We knew annealing can sometimes alter a material like silicon at a microscopic level but didn’t know if this would fix the damage,” said JunoCam imaging engineer Jacob Schaffner of Malin Space Science Systems in San Diego, which designed and developed JunoCam and is part of the team that operates it. “We commanded JunoCam’s one heater to raise the camera’s temperature to 77 degrees Fahrenheit — much warmer than typical for JunoCam — and waited with bated breath to see the results.”

Soon after the annealing process finished, JunoCam began cranking out crisp images for the next several orbits. But Juno was flying deeper and deeper into the heart of Jupiter’s radiation fields with each pass. By orbit 55, the imagery had again begun showing problems. 

“After orbit 55, our images were full of streaks and noise,” said JunoCam instrument lead Michael Ravine of Malin Space Science Systems. “We tried different schemes for processing the images to improve the quality, but nothing worked. With the close encounter of Io bearing down on us in a few weeks, it was Hail Mary time: The only thing left we hadn’t tried was to crank JunoCam’s heater all the way up and see if more extreme annealing would save us.”

Test images sent back to Earth during the annealing showed little improvement the first week. Then, with the close approach of Io only days away, the images began to improve dramatically. By the time Juno came within 930 miles (1,500 kilometers) of the volcanic moon’s surface on Dec. 30, 2023, the images were almost as good as the day the camera launched, capturing detailed views of Io’s north polar region that revealed mountain blocks covered in sulfur dioxide frosts rising sharply from the plains and previously uncharted volcanos with extensive flow fields of lava.

Testing Limits

To date, the solar-powered spacecraft has orbited Jupiter 74 times. Recently, the image noise returned during Juno’s 74th orbit.

Since first experimenting with JunoCam, the Juno team has applied derivations of this annealing technique on several Juno instruments and engineering subsystems.

“Juno is teaching us how to create and maintain spacecraft tolerant to radiation, providing insights that will benefit satellites in orbit around Earth,” said Scott Bolton, Juno’s principal investigator from the Southwest Research Institute in San Antonio. “I expect the lessons learned from Juno will be applicable to both defense and commercial satellites as well as other NASA missions.”

More About Juno

NASA’s Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Juno mission for the principal investigator, Scott Bolton, of the Southwest Research Institute in San Antonio. Juno is part of NASA’s New Frontiers Program, which is managed at NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate in Washington. The Italian Space Agency, Agenzia Spaziale Italiana, funded the Jovian InfraRed Auroral Mapper. Lockheed Martin Space in Denver built and operates the spacecraft. Various other institutions around the U.S. provided several of the other scientific instruments on Juno.

GLOBE-Trotting Science Lands in Chesapeake with NASA eClips

On June 16-17, 2025, 50 students at Camp Young in Chesapeake, Virginia traded their usual summer routines for microscopes. The NASA eClips team from the National Institute of Aerospace Center for Integrative STEM Education (NIA-CISE) taught two engaging lessons focused on macroinvertebrates and plankton, with a surprising star of the show – mosquitoes!

Camp Young, a Title I camp program serving students from Norfolk Public Schools, provides year-round, environmental science-based learning. The NASA eClips’ visit reinforced their mission to help students explore their environment on the Elizabeth River while seeing its place in the Earth System.

The lessons, designed for students in grades 3 through 8, were inspired by NASA’s GLOBE (Global Learning and Observations to Benefit the Environment) program, which encourages people around the world to collect and share environmental data as ‘citizen scientists’. This is where mosquitos stole the show! The lesson focuses on how these tiny insects can serve as indicators of climate and habitat change. By identifying mosquito larvae and understanding their breeding environments, students contributed to the bigger picture of global health and environmental monitoring, right from their own backyard.

During this experience, Camp Young’s stunning waterfront on the Elizabeth River was turned into a living laboratory. With phytoplankton nets, petri dishes, and sample jars in hand, campers ventured into the field to collect real environmental data, bringing their findings back to a cabin-turned-classroom to analyze them with scientific tools, including microscopes provided by the NASA eClips team.

Rather than just reading about ecosystems and the kinds of scientific questions that arise within them, students got to experience them firsthand and experience real science in the field. “It’s one thing to talk about microscopic marine organisms,” one instructor noted, “but it’s another thing entirely when students can actually see them swimming in a droplet from the river.”

The NASA eClips project provides educators with standards-based videos, activities, and lessons to increase STEM literacy through the lens of NASA. It is supported by NASA under cooperative agreement award number NNX16AB91A and is part of NASA’s Science Activation Portfolio.

The Day Earth Smiled

Mon, 07/21/2025 - 12:22pm
On July 19, 2013, in an event celebrated the world over, NASA’s Cassini spacecraft slipped into Saturn’s shadow and turned to image the planet, seven of its moons, its inner rings, and, in the background, our home planet, Earth.NASA/JPL-Caltech/SSI

On July 19, 2013, NASA’s Cassini spacecraft had a rare opportunity to image Saturn and, far in the background, Earth. This image spans about 404,880 miles (651,591 kilometers) across.

With the Sun’s powerful and potentially damaging rays eclipsed by Saturn itself, Cassini’s onboard cameras were able to take advantage of this unique viewing geometry. They acquired a panoramic mosaic of the Saturn system that allows scientists to see details in the rings and throughout the system as they are backlit by the sun. This mosaic is special as it marks the third time our home planet was imaged from the outer solar system; the second time it was imaged by Cassini from Saturn’s orbit; and the first time ever that inhabitants of Earth were made aware in advance that their photo would be taken from such a great distance.

Before the mission ended in 2017, Cassini was already a powerful influence on future exploration. Lessons learned during Cassini’s mission are being applied in NASA’s Europa Clipper mission. The mission uses an orbital tour design derived from the way Cassini explored Saturn. Launched in 2024, Europa Clipper will reach Jupiter in April 2030 and make dozens of flybys of the planet’s icy moon to determine whether there are places below the surface that could support life.

5 Things to Know About Powerful New U.S.-India Satellite, NISAR

Mon, 07/21/2025 - 11:33am

6 min read

Preparations for Next Moonwalk Simulations Underway (and Underwater) Information provided by the NASA-ISRO Synthetic Aperture Radar mission (NISAR) will help to protect and inform communities around the world. The data will aid in managing agricultural fields, monitoring volcanoes, and tracking land-based ice including glaciers.NASA/JPL-Caltech

Lee esta historia en español aquí.

Data from NISAR will map changes to Earth’s surface, helping improve crop management, natural hazard monitoring, and tracking of sea ice and glaciers.

A new U.S.-India satellite called NISAR (NASA-ISRO Synthetic Aperture Radar) will provide high-resolution data enabling scientists to comprehensively monitor the planet’s land and ice surfaces like never before, building a detailed record of how they shift over time. Hailed as a critical part of a pioneering year for U.S.-India civil space cooperation by President Trump and Prime Minister Modi during their visit in Washington in February, the NISAR launch will advance U.S.-India cooperation and benefit the U.S. in the areas of disaster response and agriculture.

As the first joint satellite mission between NASA and the Indian Space Research Organisation (ISRO), NISAR marks a new chapter in the growing collaboration between the two space agencies. Years in the making, the launch of NISAR builds on a strong heritage of successful programs, including Chandrayaan-1 and the recent Axiom Mission 4, which saw ISRO and NASA astronauts living and working together aboard the International Space Station for the first time.

The information NISAR provides will help decision-makers, communities, and scientists monitor agricultural fields, refine understanding of natural hazards such as landslides and earthquakes, and help teams prepare for and respond to disasters like hurricanes, floods, and volcanic eruptions. The satellite will also provide key global observations of changes to ice sheets, glaciers, and permafrost, as well as forests and wetlands.

The NISAR mission is slated to launch no earlier than July 30 from Satish Dhawan Space Centre on India’s southeastern coast aboard an ISRO Geosynchronous Satellite Launch Vehicle.

Here are five things to know about NISAR:

1. The NISAR satellite will provide a 3D view of Earth’s land and ice.

Two synthetic aperture radars (SARs) aboard NISAR will detect changes in the planet’s surface down to fractions of an inch. The spacecraft will bounce microwave signals off Earth’s surface and receive the return signals on a radar antenna reflector measuring 39 feet (12 meters) across. The satellite’s ability to “see” through clouds and light rain, day and night, will enable data users to continuously monitor earthquake- and landslide-prone areas and determine how quickly glaciers and ice sheets are changing. It also will offer unprecedented coverage of Antarctica, information that will help with studying how the continent’s ice sheet changes over time.

2. Data from NISAR will provide critical insights to help governments and decision-makers plan for natural and human-caused hazards.

Earthquakes, volcanoes, and aging infrastructure can pose risks to lives and property. Able to see subtle changes in Earth’s surface, NISAR can help with hazard-monitoring efforts and potentially give decision-makers more time to prepare for a possible disaster. For earthquakes, NISAR will provide insights into which parts of a fault slowly move without producing quakes and which are locked together and could potentially slip. The satellite will be able to monitor the area around thousands of volcanoes, detecting land movement that could be a precursor to an eruption. When it comes to infrastructure such as levees, aqueducts, and dams, NISAR data collected over time can help managers detect if nearby land motion could jeopardize key structures, and then assess the integrity of those facilities.

3. The most advanced radar system ever launched as part of a NASA or ISRO mission, NISAR will generate more data on a daily basis than any previous Earth satellite from either agency.

About the length of a pickup truck, NISAR’s main body contains a dual-radar payload — an L-band system with a 10-inch (25-centimeter) wavelength and an S-band system with a 4-inch (10-centimeter) wavelength. Each system is sensitive to land and ice features of different sizes and specializes in detecting certain attributes, such as moisture content, surface roughness, and motion. By including both radars on one spacecraft — a first — NISAR will be more capable than previous SAR missions. These two radars, one from NASA and one from ISRO, and the data they will produce, exemplify how collaboration between spacefaring allies can achieve more than either would alone.

The radars will generate about 80 terabytes of data products per day over the course of NISAR’s prime mission. That’s roughly enough data to fill about 150 512-gigabyte hard drives each day. The information will be processed, stored, and distributed via the cloud — and accessible to all.

4. The NISAR mission will help monitor ecosystems around the world.

The mission’s two radars will monitor Earth’s land and ice-covered surfaces twice every 12 days. Their near-comprehensive coverage will include areas not previously covered by other Earth-observing radar satellites with such frequency. The NISAR satellite’s L-band radar penetrates deep into forest canopies, providing insights into forest structure, while the S-band radar is ideal for monitoring crops. The NISAR data will help researchers assess how forests, wetlands, agricultural areas, and permafrost change over time.

5. The NISAR mission marks the first collaboration between NASA and ISRO on a project of this scale and marks the next step in a long line of Earth-observing SAR missions.

The NISAR satellite features components developed on opposite sides of the planet by engineers from ISRO and NASA’s Jet Propulsion Laboratory working together. The S-band radar was built at ISRO’s Space Applications Centre in Ahmedabad, while JPL built the L-band radar in Southern California. After engineers from JPL and ISRO integrated NISAR’s instruments with a modified ISRO I3K spacecraft bus and tested the satellite, ISRO transported NISAR to Satish Dhawan Space Centre in May 2025 to prepare it for launch.

The SAR technique was invented in the U.S. in 1952 and now countries around the globe have SAR satellites for a variety of missions. NASA first used the technique with a space-based satellite in 1978 on the ocean-observing Seasat, which included the first spaceborne SAR instrument for scientific observations. In 2012, ISRO began launching SAR missions starting with Radar Imaging Satellite (RISAT-1), followed by RISAT-1A in 2022, to support a wide range of applications in India.

More About NISAR

Managed by Caltech in Pasadena, JPL leads the U.S. component of the project and provided the L-band SAR. JPL also provided the radar reflector antenna, the deployable boom, a high-rate communication subsystem for science data, GPS receivers, a solid-state recorder, and payload data subsystem. NASA’s Goddard Space Flight Center manages the Near Space Network, which will receive NISAR’s L-band data.

The ISRO Space Applications Centre is providing the mission’s S-band SAR. The U R Rao Satellite Centre is providing the spacecraft bus. The rocket is from Vikram Sarabhai Space Centre, launch services are through Satish Dhawan Space Centre, and satellite mission operations are by the ISRO Telemetry Tracking and Command Network. The National Remote Sensing Centre is responsible for S-band data reception, operational products generation, and dissemination.

Catherine Staggs: Advancing Artemis Through Contracting Expertise

Mon, 07/21/2025 - 5:14am

A lifelong baseball fan, Catherine Staggs set out with her family to visit all 30 Major League Baseball stadiums across the United States. That love of the game eventually led them to settle in Houston about eight years ago – a choice that helped lead Staggs to NASA’s Johnson Space Center, where she is a contracting officer for the agency’s Commercial Lunar Payload Services (CLPS) initiative. Through CLPS, she helps manage the contracts with commercial companies delivering science and technology to the Moon. These efforts support NASA’s Artemis campaign and lay the groundwork for continuous human presence on the lunar surface.

Official portrait of Catherine Staggs.NASA

She joined NASA as a civil servant in 2018, but Staggs’ career in the federal government stretches back to her college days. She completed an accounting co-op with the Department of Defense as a student at Clemson University in Clemson, South Carolina, and secured a full-time accounting position with the agency following her graduation. She transitioned to a business financial manager position supporting U.S. Marine Corps projects while earning an MBA from The Citadel in Charleston, South Carolina. “That position is where I started to dabble in contracting,” she said.

Staggs moved to Texas in 2014 to be closer to her boyfriend – now husband – who was stationed at Fort Hood in Killeen. She was hired as a contract compliance manager for a small, Killeen-based business that specialized in government contracts, officially launching her career in contracting. When Staggs’ husband retired from the Army, the couple decided to move to Houston because they loved to watch the Houston Astros play ball. Staggs continued working for the contracting company from her new home but missed meeting new people and collaborating with colleagues in person.

“I applied for a contract specialist job with NASA to get back into the office, and the rest is history,” she said.

Her current role at Johnson involves managing the administrative contract functions for the 13 base contracts that support CLPS, which are valued at $2.6 billion. She is also the contracting officer for Firefly’s Blue Ghost Mission-3 and helps to train and develop up-and-coming contract specialists. “I love to see the development each contract specialist has over their career,” she said. “My first Pathways intern is now working full-time for NASA as a contract specialist, and they are working to become a limited warrant contracting officer.”

Her training experience provides valuable perspective on new team members. “Everyone starts at the bottom, not knowing what they don’t know,” she said. “We all have a beginning, and we need to remember that as we welcome new employees.”

Staggs said that navigating change has at times been difficult in her career, but she strives to remain flexible and open to adjusting work and life to meet the needs of the mission. “My time at NASA has helped develop my leadership skills through confidence in myself and my team,” she said.

Catherine Staggs received a 2023 Johnson Space Center Director’s Commendation Award. From left: Johnson Acting Center Director Steve Koerner, Jeremy Staggs, AJ Staggs, Catherine Staggs, NASA Acting Associate Administrator Vanessa Wyche. NASA

She looks forward to mentoring the Artemis Generation and sharing her contracting knowledge with new team members. She also anticipates crossing more baseball stadiums off her family’s list this summer.

NASA Tests Scalable Satellite Tech to Launch Sensors Quicker

Fri, 07/18/2025 - 6:18pm

4 min read

Preparations for Next Moonwalk Simulations Underway (and Underwater)

NASA’s Athena Economical Payload Integration Cost mission, or Athena EPIC, is a test launch for an innovative, scalable space vehicle design to support future missions. The small satellite platform is engineered to share resources among the payloads onboard by managing routine functions so the individual payloads don’t have to.

This technology results in lower costs to taxpayers and a quicker path to launch.

Fully integrated, the Athena EPIC satellite undergoes performance testing in a NovaWurks cleanroom to prepare the sensor for launch. The optical module payload element may be seen near the top of the instrument with the single small telescope.NovaWurks

“Increasing the speed of discovery is foundational to NASA. Our ability to leverage access to innovative space technologies across federal agencies through industry partners is the future,” said Clayton Turner, Associate Administrator for Space Technology Mission Directorate at NASA headquarters in Washington. “Athena EPIC is a valuable demonstration of the government at its best — serving humankind to advance knowledge with existing hardware configured to operate with new technologies.”

NOAA (National Oceanic and Atmospheric Administration) and the U.S. Space Force are government partners for this demo mission. Athena EPIC’s industry partner, NovaWurks, provided the space vehicle, which utilizes a small satellite platform assembled with a Hyper-Integrated Satlet, or HISat.

Engineers at NovaWurks in Long Beach prepare to mount the optical payload subassembly (center, silver) consisting of the payload optical module and single telescope mounted between gimbals on each of two HISats on either side of the module which will allow scanning across the Earth’s surface.NovaWurks

The HISat instruments are similar in nature to a child’s toy interlocking building blocks. They’re engineered to be built into larger structures called SensorCraft. Those SensorCraft can share resources with multiple payloads and conform to different sizes and shapes to accommodate them. This easily configurable, building-block architecture allows a lot of flexibility with payload designs and concepts, ultimately giving payload providers easier, less expensive access to space and increased maneuverability between multiple orbits.

Scientists at NASA’s Langley Research Center in Hampton, Virginia, designed and built the Athena sensor payload, which consists of an optical module, a calibration module, and a newly developed sensor electronics assembly. Athena EPIC’s sensor was built with spare parts from NASA’s CERES (Clouds and the Earth’s Radiant Energy System) mission. Several different generations of CERES satellite and space station instruments have tracked Earth’s radiation budget.

“Instead of Athena carrying its own processor, we’re using the processors on the HISats to control things like our heaters and do some of the control functions that typically would be done by a processor on our payload,” said Kory Priestley, principal investigator for Athena EPIC from NASA Langley. “So, this is merging an instrument and a satellite platform into what we are calling a SensorCraft. It’s a more integrated approach. We don’t need as many capabilities built into our key instrument because it’s being brought to us by the satellite host. We obtain greater redundancy, and it simplifies our payload.”

The fully assembled and tested Athena EPIC satellite which incorporates eight HISats mounted on a mock-up of a SpaceX provided launch pedestal which will hold Athena during launch.NovaWurks

This is the first HISat mission led by NASA. Traditional satellites, like the ones that host the CERES instruments — are large, sometimes the size of a school bus, and carry multiple instruments. They tend to be custom units built with all of their own hardware and software to manage control, propulsion, cameras, carousels, processors, batteries, and more, and sometimes even require two of everything to guard against failures in the system. All of these factors, plus the need for a larger launch vehicle, significantly increase costs.

This transformational approach to getting instruments into space can reduce the cost from billions to millions per mission.  “Now we are talking about something much smaller — SensorCraft the size of a mini refrigerator,” said Priestley. “If you do have failures on orbit, you can replace these much more economically. It’s a very different approach moving forward for Earth observation.”

The Athena EPIC satellite is shown here mounted onto a vibration table during pre-launch environmental testing. The optical payload is located at the top in this picture with the two solar arrays, stowed for launch, flanking the lower half sides of the satellite.NovaWurks

Athena EPIC is scheduled to launch July 22 as a rideshare on a SpaceX Falcon 9 rocket from Vandenberg Space Force Base, California. The primary NASA payload on the launch will be the TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) mission. The TRACERS mission is led by the University of Iowa for NASA’s Heliophysics Division within the Science Mission Directorate. NASA’s Earth Science Division also provided funding for Athena EPIC.

“Langley Research Center has long been a leader in developing remote sensing instruments for in-orbit satellites. As satellites become smaller, a less traditional, more efficient path to launch is needed in order to decrease complexity while simultaneously increasing the value of exploration, science, and technology measurements for the Nation,” added Turner.

Curiosity Blog, Sols 4602-4603: On Top of the Ridge

Curiosity Blog, Sols 4602-4603: On Top of the Ridge NASA’s Mars rover Curiosity acquired this image looking along the ridge it is exploring during its planned activities for July 16, 2025. Curiosity acquired this image using its Left Navigation Camera on July 15 — Sol 4600, or Martian day 4,600 of the Mars Science Laboratory mission — at 17:12:14 UTC. NASA/JPL-Caltech

Written by Alex Innanen, Atmospheric Scientist at York University

Earth planning date: Wednesday, July 16, 2025

As we hoped, we successfully climbed the 11-meter ramp (about 36 feet) and have arrived at the top of the ridge and the start of the main boxwork region. This means we’re moving into the next phase of the boxwork campaign, which is all about assessing these features and how we can navigate our way through them, and learning everything we can about their composition.

In support of that, we’re taking a good look around at the boxwork ridges with both ChemCam and Mastcam. Both instruments are taking mosaics of the more distant ridges to get a broader view of their features. A bit closer in, Mastcam has three more mosaics: two looking at different views of “El Corral” and “Chapare,” both of which we saw in Monday’s plan, and “Meson,” which is the ridge we’ll be heading for in today’s 15-meter drive (about 49 feet).

It’s not all looking ahead, though. The workspace in front of us has a lot to offer as well. Mastcam will be turning its sights to some nearby linear features. Our workspace is also full of nodular bedrock, which is getting lots of up-close attention. ChemCam will be turning its LIBS laser on a target called “Altamora,” and MAHLI and APXS will be examining another target called “Nocarane.”

With all the geological excitement, we can still manage to squeeze in some time to keep an eye on the environment. Though we don’t always mention them, REMS, RAD, and DAN are always there working steadily away to build up our understanding of Mars’ environment. We’ll also round out the plan with a suprahorizon cloud movie and a 360-degree dust-devil survey.

Stay Cool: NASA Tests Innovative Technique for Super Cold Fuel Storage

Fri, 07/18/2025 - 3:10pm
4 Min Read Stay Cool: NASA Tests Innovative Technique for Super Cold Fuel Storage The tank for NASA’s two-stage cooling tests is lowered into a vacuum chamber in Test Stand 300 at NASA’s Marshall Space Flight Center in Huntsville, Alabama. Credits: NASA/Kathy Henkel

In the vacuum of space, where temperatures can plunge to minus 455 degrees Fahrenheit, it might seem like keeping things cold would be easy. But the reality is more complex for preserving ultra-cold fluid propellants – or fuel – that can easily overheat from onboard systems, solar radiation, and spacecraft exhaust. The solution is a method called cryogenic fluid management, a suite of technologies that stores, transfers, and measures super cold fluids for the surface of the Moon, Mars, and future long-duration spaceflight missions.

Super cold, or cryogenic, fluids like liquid hydrogen and liquid oxygen are the most common propellants for space exploration. Despite its chilling environment, space has a “hot” effect on these propellants because of their low boiling points – about minus 424 degrees Fahrenheit for liquid hydrogen and about minus 298 for liquid oxygen – putting them at risk of boiloff.

In a first-of-its-kind demonstration, teams at NASA’s Marshall Space Flight Center in Huntsville, Alabama, are testing an innovative approach to achieve zero boiloff storage of liquid hydrogen using two stages of active cooling which could prevent the loss of valuable propellant.

“Technologies for reducing propellant loss must be implemented for successful long-duration missions to deep space like the Moon and Mars,” said Kathy Henkel, acting manager of NASA’s Cryogenic Fluid Management Portfolio Project, based at NASA Marshall. “Two-stage cooling prevents propellant loss and successfully allows for long-term storage of propellants whether in transit or on the surface of a planetary body.”

The new technique, known as “tube on tank” cooling, integrates two cryocoolers, or cooling devices, to keep propellant cold and thwart multiple heat sources. Helium, chilled to about minus 424 degrees Fahrenheit, circulates through tubes attached to the outer wall of the propellant tank.

Teams installed the propellant tank in a test stand at NASA Marshall in early June, and the 90-day test campaign is scheduled to conclude in September. The tank is wrapped in a multi-layer insulation blanket that includes a thin aluminum heat shield fitted between layers. A second set of tubes, carrying helium at about minus 298 Fahrenheit, is integrated into the shield. This intermediate cooling layer intercepts and rejects incoming heat before it reaches the tank, easing the heat load on the tube-on-tank system.

To prevent dangerous pressure buildup in the propellant tank in current spaceflight systems, boiloff vapors must be vented, resulting in the loss of valuable fuel. Eliminating such propellant losses is crucial to the success of NASA’s most ambitious missions, including future crewed journeys to Mars, which will require storing large amounts of cryogenic propellant in space for months or even years. So far, cryogenic fuels have only been used for missions lasting less than a week.  

“To go to Mars and have a sustainable presence, you need to preserve cryogens for use as rocket or lander return propellant,” Henkel said. “Rockets currently control their propellant through margin, where larger tanks are designed to hold more propellant than what is needed for a mission. Propellant loss isn’t an issue with short trips because the loss is factored into this margin. But, human exploration missions to Mars or longer stays at the Moon will require a different approach because of the very large tanks that would be needed.”

The Cryogenic Fluid Management Portfolio Project is a cross-agency team based at NASA Marshall and the agency’s Glenn Research Center in Cleveland. The cryogenic portfolio’s work is under NASA’s Technology Demonstration Missions Program, part of NASA’s Space Technology Mission Directorate, and is comprised of more than 20 individual technology development activities.

NASA-Derived Textiles are Touring France by Bike

Fri, 07/18/2025 - 1:40pm

3 min read

During the Tour de France, athletes have to maintain a constant speed while bike riding for dozens of miles through cold rains and summer heat. These cyclists need gear that adapts to the different environments they encounter. One company is using a material with NASA origins to ensure these athletes stay comfortable while taking their grand tours.

Phase-change materials use basic properties of matter to maintain a steady temperature. When a substance melts from a solid to a liquid, the material absorbs heat, and when it becomes solid again, it releases that heat. In the 1980s, Triangle Research Corporation received a NASA Small Business Innovation Research award to explore how phase-change materials could be incorporated into textiles to control temperatures in spacesuit gloves. By placing phase-change materials in small capsules woven throughout a textile, these temperature-regulating properties can be tuned to the comfort of the human body. While these textiles weren’t incorporated into any gloves flown on NASA missions, they formed the basis for a new product, sold under the name Outlast.

Spacesuit gloves have to be both dexterous enough to use tools and insulating enough to protect against the temperature extremes of working in space. Working with industry, NASA explored the use of phase-change materials for these purposes, which was later commercialized under the name Outlast.Credit: NASA

Outlast has since become one of the most widely distributed temperature-regulating fabrics, found in products such as bedding, loungewear, and office chairs. It has seen especially extensive use in activewear, ranging from jogging clothes to professional sports gear. 

Founded in 2001 and based in Fréjus, France, the company Ekoï makes clothing and accessories for cyclists, particularly those who bike competitively. The company first encountered Outlast at the Performance Days fabric trade fair in Munich, Germany, and was impressed with its capabilities as well as its NASA heritage.

“When you say NASA, it’s always impressive.” said Celine Milan, director of textiles at Ekoï. “At the beginning we were even saying in here in our offices, ‘Wow, this technology was developed by NASA.’ It’s on another level.”

Ekoi’s Outlast line officially launched in July 2022, during that year’s Tour de France. Over the course of that race, the company found it improved cyclists’ performance in the event’s mountain stages, where elevation changes mean wide swings in temperature. It also improved athletes’ aerodynamics, as their jerseys could stay closed in warmer environments, rather than opening them to let in wind.

Today, Ekoï sells several products that incorporate Outlast materials, including jerseys, gloves, and socks. These products are internationally known for their NASA heritage. Whether engineering for astronaut’s comfort in space or competitive athletes, NASA aims for excellence.

Hubble Snaps Galaxy Cluster’s Portrait

Fri, 07/18/2025 - 1:23pm
This NASA/ESA Hubble Space Telescope image features the galaxy cluster Abell 209.ESA/Hubble & NASA, M. Postman, P. Kelly

A massive, spacetime-warping cluster of galaxies is the setting of today’s NASA/ESA Hubble Space Telescope image. The galaxy cluster in question is Abell 209, located 2.8 billion light-years away in the constellation Cetus (the Whale).

This Hubble image of Abell 209 shows more than a hundred galaxies, but there’s more to this cluster than even Hubble’s discerning eye can see. Abell 209’s galaxies are separated by millions of light-years, and the seemingly empty space between the galaxies is filled with hot, diffuse gas that is visible only at X-ray wavelengths. An even more elusive occupant of this galaxy cluster is dark matter: a form of matter that does not interact with light. Dark matter does not absorb, reflect, or emit light, effectively making it invisible to us. Astronomers detect dark matter by its gravitational influence on normal matter. Astronomers surmise that the universe is comprised of 5% normal matter, 25% dark matter, and 70% dark energy.

Hubble observations, like the ones used to create this image, can help astronomers answer fundamental questions about our universe, including mysteries surrounding dark matter and dark energy. These investigations leverage the immense mass of a galaxy cluster, which can bend the fabric of spacetime itself and create warped and magnified images of background galaxies and stars in a process called gravitational lensing.

While this image lacks the dramatic rings that gravitational lensing can sometimes create, Abell 209 still shows subtle signs of lensing at work, in the form of streaky, slightly curved galaxies within the cluster’s golden glow. By measuring the distortion of these galaxies, astronomers can map the distribution of mass within the cluster, illuminating the underlying cloud of dark matter. This information, which Hubble’s fine resolution and sensitive instruments help to provide, is critical for testing theories of how our universe evolved.

What You Need to Know About NASA’s SpaceX Crew-11 Mission

Fri, 07/18/2025 - 10:02am
The four crew members of NASA’s SpaceX Crew-11 mission to the International Space Station train inside a SpaceX Dragon spacecraft in Hawthorne, California. From left to right: Roscosmos cosmonaut Oleg Platonov, NASA astronauts Mike Fincke and Zena Cardman, and JAXA astronaut Kimiya YuiSpaceX

Four crew members are preparing to launch to the International Space Station as part of NASA’s SpaceX Crew-11 mission to perform research, technology demonstrations, and maintenance activities aboard the orbiting laboratory.

During the mission, Crew-11 also will contribute to NASA’s Artemis campaign by simulating Moon landing scenarios that astronauts may encounter near the lunar South Pole, showing how the space station helps prepare crews for deep space human exploration. The simulations will be performed before, during, and after their mission using handheld controllers and multiple screens to identify how changes in gravity affect spatial awareness and astronauts’ ability to pilot spacecraft, like a lunar lander.

NASA astronauts Zena Cardman and Mike Fincke, JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, and Roscosmos cosmonaut Oleg Platonov will lift off no earlier than 12:09 p.m. EDT on Thursday, July 31, from Launch Complex 39A at the agency’s Kennedy Space Center in Florida on a long-duration mission. The cadre will fly aboard a SpaceX Dragon spacecraft, named Endeavour, which previously flew NASA’s SpaceX Demo-2, Crew-2, Crew-6, and Crew-8 missions, as well as private astronaut mission Axiom Mission 1.

The flight is the 11th crew rotation mission with SpaceX to the space station as part of NASA’s Commercial Crew Program. Overall, the Crew-11 mission is the 16th crewed Dragon flight to the space station, including Demo-2 in 2020 and 11 operational crew rotations for NASA, as well as four private astronaut missions.

As support teams progress through Dragon preflight milestones for Crew-11, they also are preparing a SpaceX Falcon 9 rocket booster for its third flight. Once all rocket and spacecraft system checkouts are complete and all components are certified for flight, teams will mate Dragon to Falcon 9 in SpaceX’s hangar at the launch site. The integrated spacecraft and rocket will then be rolled to the pad and raised vertically for the crew’s dry dress rehearsal and an integrated static fire test before launch.

Following liftoff, Falcon 9 will accelerate Dragon to approximately 17,500 mph. Once in orbit, the crew, NASA, and SpaceX mission control will monitor a series of maneuvers that will guide Dragon to the forward-facing port of the station’s Harmony module. The spacecraft is designed to dock autonomously, but the crew can pilot it manually, if necessary.

After docking, Crew-11 will be welcomed aboard the station by the seven-member Expedition 73 crew, before conducting a short handover period on research and maintenance activities with the departing Crew-10 crew members. Then, NASA astronauts Anne McClain, Nichole Ayers, JAXA astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov will undock from the space station and return to Earth. Ahead of Crew-10’s return, mission teams will review weather conditions at the splashdown sites off the coast of California before departure from the station.

Cardman, Fincke, and Yui will conduct scientific research to prepare for human exploration beyond low Earth orbit and benefit humanity on Earth. Participating crew members will simulate lunar landings, test strategies to safeguard vision, and advance other human spaceflight studies led by NASA’s Human Research Program. The crew also will study plant cell division and microgravity’s effects on bacteria-killing viruses, as well as perform experiments to produce a higher volume of human stem cells and generate on-demand nutrients.

While aboard the orbiting laboratory, Crew-11 will welcome a Soyuz spacecraft in November with three new crew members, including NASA astronaut Chris Williams.  They also will bid farewell to the Soyuz carrying NASA astronaut Jonny Kim. The crew also is expected to see the arrival of the Dragon, Roscosmos Progress spacecraft, and Northrop Grumman’s Cygnus spacecraft to resupply the station.

NASA’s SpaceX Crew-11 mission will be aboard the International Space Station on Nov. 2, when the orbiting laboratory surpasses 25 years of a continuous human presence. Since the first crew expedition arrived, the space station has enabled more than 4,000 groundbreaking experiments in the unique microgravity environment, while becoming a springboard for building a low Earth orbit economy and preparing for NASA’s future exploration of the Moon and Mars.

Vision Changes on Space Station

Fri, 07/18/2025 - 10:00am

When astronauts began spending six months and more aboard the International Space Station, they started to notice changes in their vision. For example, many found that, as their mission progressed, they needed stronger reading glasses. Researchers studying this phenomenon identified swelling in the optic disc, which is where the optic nerve enters the retina, and flattening of the eye shape. These symptoms became known as Space-Associated Neuro-Ocular Syndrome (SANS).

Microgravity causes a person’s blood and cerebrospinal fluid to shift toward the head and studies have suggested that these fluid shifts may be an underlying cause of SANS. A current investigation, Thigh Cuff, examines whether tight leg cuffs change the way fluid moves around inside the body, especially around the eyes and in the heart and blood vessels. If so, the cuffs could serve as a countermeasure against the problems associated with fluid shifts, including SANS. A simple and easy-to-use tool to counter the headward shift of body fluids could help protect astronauts on future missions to the Moon and Mars. The cuffs also could treat conditions on Earth that cause fluid to build up in the head or upper body, such as long-term bed rest and certain diseases.

The Fluid Shifts investigation, conducted from 2015 through 2020, was the first to reveal changes in how blood drains from the brain in microgravity. Vision Impairment and Intracranial Pressure (VIIP) began testing the role those fluid shifts and resulting increased brain fluid pressure might play in the development of SANS. This research used a variety of measures including clinical eye exams with and without dilatation, imaging of the retina and associated blood vessels and nerves, noninvasive imaging to measure the thickness of retinal structures, and magnetic resonance imaging of the eye and optic nerve. In addition, approximately 300 astronauts completed questionnaires to document vision changes during their missions.

In one paper published from the research, scientists described how these imaging techniques have improved the understanding of SANS. The authors summarized emerging research on developing a head-mounted virtual reality display that can conduct multimodal, noninvasive assessment to help diagnose SANS.

Other researchers determined that measuring the optic nerve sheath diameter shows promise as a way to identify and quantify eye and vision changes during spaceflight. The paper also makes recommendations for standardizing imaging tools, measurement techniques, and other aspects of study design.

Another paper reported on an individual astronaut who had more severe than usual changes after a six-month spaceflight and certain factors that may have contributed. Researchers also observed improvement in the individual’s symptoms that may have been due to B vitamin supplementation and lower cabin carbon dioxide levels following departure of some crew members. While a single case does not allow researchers to determine cause and effect, the magnitude of the improvements suggest this individual may be more affected by environmental conditions such as carbon dioxide. This may have been the first attempt to mitigate SANS with inflight B vitamin supplementation.

SANSORI, a CSA (Canadian Space Agency) investigation, used an imaging technique called Optical Coherence Tomography to examine whether reduced stiffness of eye tissue contributes to SANS. On Earth, changes in stiffness of the tissue around the eyeball have been associated with aging and conditions such as glaucoma and myopia. Researchers found that long-duration spaceflight affected the mechanical properties of eye tissues, which could contribute to the development of SANS. This finding could improve understanding of eye changes during spaceflight and in aging patients on Earth.

Genetic changes, artificial gravity

The MHU-8 investigation from JAXA (Japan Aerospace Exploration Agency), which examined changes in DNA and gene expression in mice after spaceflight, found changes in the optic nerve and retinal tissue. Researchers also found that artificial gravity may reduce these changes and could serve as a countermeasure on future missions.

These and other studies ultimately could help researchers prevent, diagnose, and treat vision impairment in crew members and people on Earth.

Hubble Digs Up Galactic Time Capsule

Hubble Digs Up Galactic Time Capsule This NASA/ESA Hubble Space Telescope image features the globular cluster NGC 1786.ESA/Hubble & NASA, M. Monelli; Acknowledgment: M. H. Özsaraç

This NASA/ESA Hubble Space Telescope image features the field of stars that is NGC 1786. The globular cluster is located in the Large Magellanic Cloud (LMC), a small satellite galaxy of the Milky Way Galaxy that is approximately 160,000 light-years away from Earth. NGC 1786 itself is in the constellation Dorado. It was discovered in the year 1835 by Sir John Herschel.

The data for this image comes from an observing program that compares old globular clusters in nearby dwarf galaxies — the LMC, the Small Magellanic Cloud, and the Fornax dwarf spheroidal galaxy — to globular clusters in the Milky Way galaxy. Our galaxy contains over 150 of these old, spherical collections of tightly-bound stars, which astronomers have studied in depth — especially with Hubble images like this one, which show them in previously unattainable detail. Being very stable and long-lived, globular clusters act as galactic time capsules, preserving stars from the earliest stages of a galaxy’s formation.

Astronomers once thought that stars in a globular cluster all formed together at about the same time, but the study of old globular clusters in our galaxy uncovered multiple populations of stars with different ages. To use globular clusters as historical markers, we must understand how they form and where these stars of varying ages come from. This observing program examined old globular clusters like NGC 1786 in these external galaxies to see if they, too, contain multiple populations of stars. This research can tell us more about how the LMC originally formed, but also the Milky Way Galaxy, too.
