Former NASA astronaut Shane Kimbrough is photographed as he left the airlock hatch during a spacewalk on Jan. 13, 2017. Kimbrough performed nine spacewalks during his three spaceflights. He retired in July 2022.
Astronauts conduct spacewalks to perform maintenance on the space station, install new equipment, or deploy science experiments. These activities also inform future missions like the Artemis campaign and exploring Mars; through NASA’s Extravehicular Activity and Human Surface Mobility Program, the agency develops next-generation spacesuits, human-rated rovers (pressurized and unpressurized), and tools, along with all the necessary spacewalking support systems for use in microgravity, on the lunar surface and, eventually, on other planets.

NASA Seeks Proposals for 2026 Human Exploration Rover Challenge
3 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater)NASA now is accepting proposals from student teams for a contest to design, build, and test rovers for Moon and Mars exploration through Sept. 15.
Known as the Human Exploration Rover Challenge, student rovers should be capable of traversing a course while completing mission tasks. The challenge handbook has guidelines for remote-controlled and human-powered divisions.
The cover of the HERC 2026 handbook, which is now available online.“Last year, we saw a lot of success with the debut of our remote-controlled division and the addition of middle school teams,” said Vemitra Alexander, the activity lead for the challenge at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “We’re looking forward to building on both our remote-controlled and human-powered divisions with new challenges for the students, including rover automation.”
This year’s mission mimics future Artemis missions to the lunar surface. Teams are challenged to test samples of soil, water, and air from sites along a half-mile course that includes a simulated field of asteroid debris, boulders, erosion ruts, crevasses, and an ancient streambed. Human-powered rover teams will play the role of two astronauts in a lunar terrain vehicle and must use a custom-built task tool to manually collect samples needed for testing. Remote-controlled rover teams will act as a pressurized rover, and the rover itself will contain the tools necessary to collect and test samples onboard.
“NASA’s Human Exploration Rover Challenge creates opportunities for students to develop the skills they need to be successful STEM professionals,” said Alexander. “This challenge will help students see themselves in the mission and give them the hands-on experience needed to advance technology and become the workforce of tomorrow.”
Seventy-five teams comprised of more than 500 students participated in the agency’s 31st rover challenge in 2025. Participants represented 35 colleges and universities, 38 high schools, and two middle schools, across 20 states, Puerto Rico, and 16 nations around the world.
The 32nd annual competition will culminate with an in-person event April 9-11, 2026, at the U.S. Space & Rocket Center near NASA Marshall.
The rover challenge is one of NASA’s Artemis Student Challenges, reflecting the goals of the Artemis campaign, which seeks to explore the Moon for scientific discovery, technology advancement, and to learn how to live and work on another world as we prepare for human missions to Mars. NASA uses such challenges to encourage students to pursue degrees and careers in the fields of science, technology, engineering, and mathematics.
Since its inception in 1994, more than 15,000 students have participated in the rover challenge – with many former students now working at NASA or within the aerospace industry.

Hubble Examines Low Brightness, High Interest Galaxy This NASA/ESA Hubble Space Telescope image features a portion of the spiral galaxy NGC 45. ESA/Hubble & NASA, D. Calzetti, R. Chandar; Acknowledgment: M. H. ÖzsaraçThis NASA/ESA Hubble Space Telescope image zooms in on the feathery spiral arms of the galaxy NGC 45, which lies just 22 million light-years away in the constellation Cetus (the Whale).
The portrait uses data drawn from two complementary observing programs. The first took a broad view of 50 nearby galaxies, leveraging Hubble’s ability to observe ultraviolet through visible into near-infrared light to study star formation in these galaxies. The second program examined many of the same nearby galaxies as the first, narrowing in on a particular wavelength of red light called H-alpha. Star-forming nebulae are powerful producers of H-alpha light, and several of these regions are visible across NGC 45 as bright pink-red patches.
These observing programs aimed to study star formation in galaxies of different sizes, structures, and degrees of isolation — and NGC 45 is a particularly interesting target. Though it may appear to be a regular spiral galaxy, NGC 45 is a remarkable type called a low surface brightness galaxy.
Low surface brightness galaxies are fainter than the night sky itself, making them incredibly difficult to detect. They appear unexpectedly faint because they have relatively few stars for the volume of gas and dark matter they carry. In the decades since astronomers serendipitously discovered the first low surface brightness galaxy in 1986, researchers have learned that 30–60% of all galaxies may fall into this category. Studying these hard-to-detect galaxies is key to understanding how galaxies form and evolve, and Hubble’s sensitive instruments are equal to the task.

Summer Triangle Corner: Altair
3 min read
Summer Triangle Corner: Altair A map of the asterism known as the Summer Triangle. This asterism is made up of three stars: Vega in the Lyra constellation, Altair in the Aquila constellation, and Deneb in the Cygnus constellation. Stellarium WebAltair is the last stop on our trip around the Summer Triangle! The last star in the asterism to rise for Northern Hemisphere observers before summer begins, brilliant Altair is high overhead at sunset at the end of the season in September. Altair might be the most unusual of the three stars of the Triangle, due to its great speed: this star spins so rapidly that it appears “squished.”
Altair is the brightest star in the constellation of Aquila, the Eagle. A very bright star, Altair holds a notable place in the mythologies of cultures around the world. As discussed in a previous article, Altair represents the cowherd in the ancient tale “Cowherd and the Weaver Girl.” While described as part of an eagle by ancient peoples around the Mediterranean, it was also seen as part of an eagle by the Koori people in Australia. They saw the star itself as representing a wedge-tailed eagle, and two nearby stars as his wives, a pair of black swans. More recently, one of the first home computers was named after the star: the Altair 8800.
A rapidly spinning star darkens and exhibits a bulge at the equator, as shown by the model at left. At right, an actual CHARA interferometer image of the star Altair. NASA/NSF/Center for High Angular Resolution Astronomy/Zina DeretskyAltair’s rapid spinning was first detected in the 1960s. The close observations that followed tested the limits of technology available to astronomers, eventually resulting in direct images of the star’s shape and surface by using a technique called interferometry, which combines the light from two or more instruments to produce a single image. Predictions about how the surface of a rapidly spinning massive star would appear held true to the observations; models predicted a squashed, almost “pumpkin-like” shape instead of a round sphere, along with a dimming effect along the widened equator, and the observations confirmed this!
This equatorial dimming is due to a phenomenon called gravity darkening. Altair is wider at the equator than it is at the poles due to centrifugal force, resulting in the star’s mass bulging outwards at the equator. This results in the denser poles of the star being hotter and brighter, and the less dense equator being cooler and therefore dimmer. This doesn’t mean that the equator of Altair or other rapidly spinning stars are actually dark, but rather that the equator is dark in comparison to the poles; this is similar in a sense to sunspots. If you were to observe a sunspot on its own, it would appear blindingly bright, but it is cooler than the surrounding plasma in the Sun and so appears dark in contrast.
As summer winds down, you can still take a Trip Around the Summer Triangle with this activity from the Night Sky Network. Mark some of the sights in and around the Summer Triangle at: bit.ly/TriangleTrip.

Curiosity Blog, Sols 4627-4628: A Ridge Stop in the Boxworks NASA’s Mars rover Curiosity acquired this close-up view of the rock target “Bococo” at the intersection of several boxwork ridges, showing bright millimeter-scale nodules likely to be calcium sulfate. Curiosity acquired this image using its Mars Hand Lens Imager (MAHLI), located on the turret at the end of the rover’s robotic arm, which uses an onboard focusing process to merge multiple images of the same target, acquired at different focus positions, to bring all (or, as many as possible) features into focus in a single image. Curiosity performed the merge on Aug. 10, 2025 — Sol 4625, or Martian day 4,625 of the Mars Science Laboratory mission — at 08:00:39 UTC. NASA/JPL-Caltech/MSSSEarth planning date: Monday Aug. 11, 2025
Written by Lucy Lim, Planetary Scientist at NASA’s Goddard Space Flight Center
On the Curiosity team, we’re continuing our exploration of the boxwork-forming region in Gale Crater. A successful 25-meter drive (about 82 feet) brought the rover from the “peace sign” ridge intersection to a new ridge site. Several imaging investigations were pursued in today’s plan, including Mastcam observations of a potential incipient hollow (“Laguna Miniques”), and of a number of troughs to examine how fractures transition from bedrock to regolith.
With six wheels on the ground, Curiosity was also ready to deploy the rover arm for some contact science. APXS and MAHLI measurements were planned to explore the local bedrock at two points with a brushed (DRT) measurement (“Santa Catalina”) and a non-DRT measurement (“Puerto Teresa”). A third MAHLI observation will be co-targeted with one of the LIBS geochemical measurements on a light-toned block, “Palma Seca.” Because we’re in nominal sols for this plan, we were able to plan a second targeted LIBS activity to measure the composition of a high-relief feature on another block, “Yavari” before the drive.
The auto-targeted LIBS (AEGIS) that executed post-drive on sol 4626 had fallen on a bedrock target and will be documented in high resolution via Mastcam imaging.
Two long-distance imaging mosaics were planned for the ChemCam remote imager (RMI): one on a potential scarp and lens in sediments exposed on the “Mishe Mokwa” butte in the strata above the rover’s current position, and the second on an east-facing boxwork ridge with apparently exposed cross-bedding that may be related to the previously explored “Volcán Peña Blanca” ridge.
As usual, the modern Martian environment will also be observed with camera measurements of the atmospheric opacity, a Navcam movie to watch for dust lifting, and the usual REMS and DAN passive monitoring of the temperature, humidity, and neutron flux at the rover’s location.
The next drive is planned to bring us to a spot in a hollow where we hope to plan contact science on the erosionally recessive hollow bedrock in addition to imaging with a good view of the rock layers exposed in the wall of another prominent ridge.

NASA Seeks Industry Feedback on Fission Surface Power
As part of the agency’s initiative to return humanity to the Moon and eventually send the first astronaut – an American – to Mars, NASA is surveying industry for interest and feedback on a fission surface power system, through a Request for Information issued Thursday.
Earlier this month, NASA declared its intent to put a nuclear reactor on the Moon by the mid-2030s to support lunar exploration, provide power generation on Mars, and strengthen national security in space.
“Today’s call for industry input is an important step toward engaging the commercial space industry in powering the lunar economy and enabling future human exploration on Mars,” said Steve Sinacore, Fission Surface Power program executive at NASA’s Glenn Research Center in Cleveland. “Developing a safe, reliable, and efficient power supply is key to unlocking the future of human space exploration and ensuring America retains its dominance in space.”
Building on its previous work, NASA will work with industry to design a fission surface power system that would provide at least 100 kilowatts of electrical power, have a mass allocation of less than 15 metric tons, and use a closed Brayton cycle power conversion system, which converts heat to electricity.
NASA’s new Fission Surface Power effort builds on more than 60 years of agency experience in exploration technology. In 2022, NASA awarded three contracts for fission surface power system concepts for the Moon. In addition, NASA has used nuclear power sources in spacecraft and rovers over the years.
The size, weight, and power capability of fission systems make them an effective continuous power supply regardless of location. Additionally, a nuclear reactor could be placed in lunar regions where sunlight cannot reach and could sustain nights on the Moon which can last more than 14 Earth days near the poles.
Nuclear power is a key element for NASA’s Artemis missions and supporting a robust lunar economy. The Request for Information invites innovators to contribute to this effort, allowing NASA to access industry expertise and bolstering American ingenuity.
Responses to the Request for Information are due Thursday, Aug. 21, and could be used to finalize a potential opportunity later this year.
The Fission Surface Power effort is managed through NASA Glenn. The power system development is funded by the agency’s Exploration Systems Development Mission Directorate Moon to Mars Program.

When the Crew-11 astronauts launched to the International Space Station on August 1, 2025, they carried with them another chapter in space farming: the latest VEG-03 experiments, complete with seed pillows ready for planting.
Growing plants provides nutrition for astronauts, as well as psychological benefits that help maintain crew morale during missions.
During VEG-03 MNO, astronauts will be able to choose what they want to grow from a seed library including Wasabi mustard greens, Red Russian Kale, and Dragoon lettuce.
From Seed to Space Salad
The experiment takes place inside Veggie, a chamber about the size of carry-on luggage. The system uses red, blue, and green LED lights to provide the right spectrum for plant growth. Clear flexible bellows — accordion-like walls that expand to accommodate maturing plants — create a semi-controlled environment around the growing area.
Astronauts plant thin strips containing their selected seeds into fabric “seed pillows” filled with a special clay-based growing medium and controlled-release fertilizer. The clay, similar to what’s used on baseball fields, helps distribute water and air around the roots in the microgravity environment.
Crew members will monitor the plants, add water as needed, and document growth through regular photographs. At harvest time, astronauts will eat some of the fresh produce while freezing other samples for return to Earth, where scientists will analyze their nutritional content and safety.
How this benefits space explorationFresh food will become critical as astronauts venture farther from Earth on missions to the Moon and Mars. NASA aims to validate different kinds of crops to add variety to astronaut diets during long-duration space exploration missions, while giving crew members more control over what they grow and eat.
How this benefits humanityThe techniques developed for growing crops in space’s challenging conditions may also improve agricultural practices on Earth. Indoor crop cultivation approaches similar to what astronauts do in Veggie might also be adapted for horticultural therapy programs, giving elderly or disabled individuals new ways to experience gardening when traditional methods aren’t accessible.

When the Crew-11 astronauts launched to the International Space Station on August 1, 2025, they carried with them another chapter in space farming: the latest VEG-03 experiments, complete with seed pillows ready for planting.
Growing plants provides nutrition for astronauts, as well as psychological benefits that help maintain crew morale during missions.
During VEG-03 MNO, astronauts will be able to choose what they want to grow from a seed library including Wasabi mustard greens, Red Russian Kale, and Dragoon lettuce.
From Seed to Space Salad
The experiment takes place inside Veggie, a chamber about the size of carry-on luggage. The system uses red, blue, and green LED lights to provide the right spectrum for plant growth. Clear flexible bellows — accordion-like walls that expand to accommodate maturing plants — create a semi-controlled environment around the growing area.
Astronauts plant thin strips containing their selected seeds into fabric “seed pillows” filled with a special clay-based growing medium and controlled-release fertilizer. The clay, similar to what’s used on baseball fields, helps distribute water and air around the roots in the microgravity environment.
Crew members will monitor the plants, add water as needed, and document growth through regular photographs. At harvest time, astronauts will eat some of the fresh produce while freezing other samples for return to Earth, where scientists will analyze their nutritional content and safety.
How this benefits space explorationFresh food will become critical as astronauts venture farther from Earth on missions to the Moon and Mars. NASA aims to validate different kinds of crops to add variety to astronaut diets during long-duration space exploration missions, while giving crew members more control over what they grow and eat.
How this benefits humanityThe techniques developed for growing crops in space’s challenging conditions may also improve agricultural practices on Earth. Indoor crop cultivation approaches similar to what astronauts do in Veggie might also be adapted for horticultural therapy programs, giving elderly or disabled individuals new ways to experience gardening when traditional methods aren’t accessible.

After Storied 34 Year Career, Steve Platnick Retires from NASA
Dr. Steven “Steve” Platnick stepped down from his role at NASA on August 8, 2025, after more than three decades of public service. Steve began his career at NASA as a physical scientist at Goddard Space Flight Center in 2002. He moved to the Earth Science Division in 2009, where he has served in various senior management roles, including as the Earth Observing System (EOS) Senior Project Scientist. In this role, he led the EOS Project Science Office and continued periodic meetings of the EOS Project Scientists, initiated by Michael King during his tenure. Steve expanded these meetings to include representatives of non-EOS Earth observing missions and representatives from Earth Science Mission Operations (ESMO). In addition, Steve was named Deputy Director for Atmospheres in the Earth Science Division in January 2015 and served in this position until July 2024.
Dr. Steve Platnick Image credit: NASADuring his time at NASA, Steve played an integral role in the development, sustainability, and advancement of NASA’s Earth Observing System platforms. From January 2003 – February 2010, Steve served as Deputy Project Scientist for Aqua. In this role, he applied his expertise in theoretical and experimental studies of satellite, aircraft, and ground-based cloud remote sensing to improve algorithms to benefit the data gathered from remote observing systems.
Taking the Lead to Improve Algorithms
Steve was actively involved in the Moderate Resolution Imaging Spectroradiometer (MODIS) Science Team, serving as the MODIS Atmosphere Team Lead. Steve helped advance several key components of the MODIS instrument, which flies on NASA’s Terra and Aqua platforms. He led a team that enhanced, maintained, and evaluated MODIS algorithms that support the Level-2 (L2) Cloud Optical/Microphysical Properties components (e.g., COD06 and MYD06) for MODIS on Terra and Aqua. The algorithms were designed to retrieve thermodynamic phase, optical thickness, effective particle radius, and water path for liquid and ice clouds. The team’s work also contributes to L3 products that address cloud mask, aerosols, clouds, and clear sky radiance for data within 1° grids over one-day, eight-day, and one-month repeat cycles. Under Steve’s leadership, the team also developed L2 products (e.g., MODATML2 and MYDATML2) that include essential atmosphere datasets of samples collected at 5–10 km (3–6 mi) that is consistent with L3 products to ease storage requirements of core atmospheric data.
Steve is also a member of the Suomi-National Polar-orbiting Partnership (Suomi NPP) Atmosphere Team, working on operational cloud optical and microphysical products. In this role, he contributed to algorithm development and refinement for the Cloud Product. In particular, he helped address a critical gap in the Visible Infrared Imaging Radiometer Suite (VIIRS) spectral channel, which was not designed to collect information for carbon dioxide (CO2) slicing and water vapor data in the same way as MODIS. Steve and his colleagues developed a suite of L2 algorithms for the spectral channels that were common to both MODIS and VIIRS to address cloud mask and cloud optical/microphysical properties. Through these efforts, the project has established a continuous cloud data record gathered from both instruments from 2017 to the present.
Steve also participated in numerous other working groups during the past 30 years. He participated in the Global Energy and Water Exchanges (GEWEX) Cloud Assessment Working Group (2008–present), Arctic Radiation-Cloud-Aerosol-Surface Interaction Experiment (ARCSIX) Science Team (2023–present), ObseRvations of Aerosols above CLouds and their intEractionS (ORACLES) Earth–Venture Suborbital (EVS)-2 Science Team (2014–2023), Deep Space Climate Observatory (DSCOVR) Science Team (2014–present), Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) Science Team (2014–2023), PACE Science Definition Team, Deputy Chair (2011–2012), Glory Science Team (2010–2014) NASA Observations for Modeling Intercomparison Studies (obs4MIPs) Working Group (2011), Advanced Composition Explorer (ACE) Science Definition Team (2009–2011), and Geostationary Operational Environmental Satellites (GOES) R-series Advanced Baseline Imager (ABI) Cloud Team (2005–2009).
Steve has also participated in numerous major airborne field campaigns in various roles, including: GSFC Lidar Observation and Validation Experiment (GLOVE, 2025), PACE Postlaunch Airborne eXperiment (PAX, 2024), the Westcoast & Heartland Hyperspectral Microwave Sensor Intensive Experiment (WH2yMSIE, 2024), ORACLES Science Team (2015–2019), Studies of Emissions and Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys (SEAC4RS) Science Team (2011–2015), Tropical Composition, Cloud and Climate Coupling (TC4) Management Team (2007), Cirrus Regional Study of Tropical Anvils and Cirrus Layers – Florida Area Cirrus Experiment (CRYSTAL-FACE) Science Management Team (2002), Southern Africa Fire-Atmosphere Research Initiative (SAFARI, 2000), First ISCCP Regional Experiment (FIRE) Arctic Cloud Experiment (ACE) (1998), Mikulski Archive for Space Telescopes (MAST, 1994), and ACE (1992).
Supporting Earth Science Communications
Through his senior leadership roles within ESD Steve has been supportive of the activities of NASA’s Science Support Office (SSO). He has participated in many NASA Science exhibits at both national and international scientific conferences, including serving as a Hyperwall presenter numerous times. He has met with task leaders frequently and has advocated on behalf of the SSO to management at NASA Headquarters, GSFC, and Global Sciences & Technology Inc.
For The Earth Observer newsletter publication team in particular, Steve replaced Michael King as Acting EOS Senior Project Scientist in June 2008, taking over the authorship of “The Editor’s Corner” beginning with the May–June 2008 issue [Volume 20, Issue 3]. The Acting label was removed beginning with the January–February 2010 issue [Volume 22, Issue 1]. Steve has been a champion of continuing to retain a historical record of NASA meetings to maintain a chronology of advances made by different groups within the NASA Earth Science community. He was supportive of the Executive Editor’s efforts to create a series called “Perspectives on EOS,” which ran from 2008–2011 and told the stories of the early years of the EOS Program from the point of view of those who lived them. He also supported the development of articles to commemorate the 25th and 30th anniversary of The Earth Observer. Later, Steve helped guide the transition of the newsletterfrom a print publication – the November–December 2022 issue was the last printed issue – to fully online by July 2024, a few months after the publication’s 35th anniversary. The Earth Observer team will miss Steve’s keen insight, historical perspective, and encouragement that he has shown through his leadership for the past 85 issues of print and online publications.

Small Companies Win Big in NASA’s TechLeap Challenge
NASA announced 10 winning teams for its latest TechLeap Prize — the Space Technology Payload Challenge — on June 26. The winners emerged from a record-breaking field of more than 200 applicants to earn cash prizes worth up to $500,000, if they have a flight-ready unit. Recipients may also have the opportunity to flight test their technologies.
NASA’s Biological and Physical Sciences (BPS) division is supporting the emerging space economy through challenges like TechLeap. The projects receive funding through the Commercially Enabled Rapid Space Science (CERISS) initiative, which pairs government research goals with commercial innovation.
Two awardees’ capabilities specifically address BPS research priorities, which include conducting investigations that inform future space crops and advance precision health.
Ambrosia Space Manufacturing Corporation is developing a centrifuge system to separate nutrients from cell cultures — potentially creating space-based food processing that could turn algae into digestible meals for astronauts.
Helogen Corporation is building an automated laboratory system that can run biological experiments without requiring astronaut involvement and may be able to transmit real-time data to researchers on Earth without having to wait for physical samples to return.
“The innovations of these small- and midsize businesses could enable NASA to accelerate the pace of critical research,” says Dan Walsh, BPS’s program executive for CERISS. “It’s also an example of NASA enabling the emerging space industry to grow and thrive beyond big corporations.”
Small Packages with Big AmbitionsEvery inch and ounce counts on a spacecraft, which means the winning teams have to think small while solving big problems.
Commercial companies play a pivotal role in enabling space-based research — they bring fresh approaches to ongoing challenges. But space missions demand a different kind of innovation, and TechLeap teams face both time and size constraints for their experiments.
Winners have six to nine months to demonstrate that their concepts work. That’s a significant contrast from traditional space technology development, which can stretch for years.
The research serves a larger purpose as well. The technology helps NASA “know before we go” on longer, deep-space missions to the Moon and Mars. Understanding how technologies behave in microgravity or extreme environments can prevent costly failures when astronauts are far from Earth.
Small investments in proof-of-concept technologies can bring in a high ROI. With the TechLeap Prize, BPS is betting that big ideas will come in small packages.
