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.

Captured at a location called “Falbreen,” this enhanced-color mosaic features decep-tively blue skies and the 43rd rock abrasion (the white patch at center-left) of the NASA Perseverance rover’s mission at Mars. The 96 images stitched together to create this 360-degree view were acquired May 26, 2025.NASA/JPL-Caltech/ASU/MSSS In this natural-color version of the “Falbreen” panorama, colors have not been enhanced and the sky appears more reddish. Visible still is Perseverance’s 43rd rock abrasion (the white patch at center-left). The 96 images stitched together to create this 360-degree view were acquired May 26, 2025.NASA/JPL-Caltech/ASU/MSSS ‘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 Boulder
One detail that caught the science team’s attention is a large rock that appears to sit atop a dark, crescent-shaped sand ripple to the right of the mosaic’s center, about 14 feet (4.4 meters) from the rover. Geologists call this type of rock a “float rock” because it was more than likely formed someplace else and transported to its current location. Whether this one arrived by a landslide, water, or wind is unknown, but the science team suspects it got here before the sand ripple formed.
The bright white circle just left of center and near the bottom of the image is an abrasion patch. This is the 43rd rock Perseverance has abraded since it landed on Mars. Two inches (5 centimeters) wide, the shallow patch is made with the rover’s drill and enables the science team to see what’s beneath the weathered, dusty surface of a rock before deciding to drill a core sample that would be stored in one of the mission’s titanium sample tubes.
The rover made this abrasion on May 22 and performed proximity science (a detailed analysis of Martian rocks and soil) with its arm-mounted instruments two days later. The science team wanted to learn about Falbreen because it’s situated within what may be some of the oldest terrain Perseverance has ever explored — perhaps even older than Jezero Crater.
Tracks from the rover’s journey to the location can be seen toward the mosaic’s right edge. About 300 feet (90 meters) away, they veer to the left, disappearing from sight at a previous geologic stop the science team calls “Kenmore.”
A little more than halfway up the mosaic, sweeping from one edge to the other, is the transition from lighter-toned to darker-toned rocks. This is the boundary line, or contact, between two geologic units. The flat, lighter-colored rocks nearer to the rover are rich in the mineral olivine, while the darker rocks farther away are believed to be much older clay-bearing rocks.

This view of tracks trailing NASA’s Curiosity rover was captured July 26, 2025, as the rover simultaneously relayed data to a Mars orbiter.NASA/JPL-Caltech NASA’s Curiosity rover captured a view of its tracks on July 26, 2025. The robotic scientist is now exploring a region of lower Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain. The pale peak of the mountain can be seen at top right; the rim of Gale Crater, within which the mountain sits, is on the horizon at top left. Curiosity touched down on the crater floor 13 years ago.
Recently, the rover rolled into a region filled with boxwork formations. Studying these formations could reveal whether microbial life could have survived in the Martian subsurface eons ago, extending the period of habitability farther into when the planet was drying out.

NASA’s SpaceX Crew-10 Looks Back at Science Mission
NASA’s SpaceX Crew-10 mission with agency astronauts Anne McClain and Nichole Ayers, JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov is preparing to return to Earth in early August after a long-duration mission aboard the International Space Station. During their stay, McClain, Ayers, and Onishi completed dozens of experiments and technology demonstrations, helping push the boundaries of scientific discovery aboard the orbiting laboratory.
Here’s a look at some scientific milestones accomplished during the Crew-10 mission:
Orbital effects on plants
NASA The canisters floating in the cupola of the International Space Station contain wild-type and genetically-modified thale cress plants for the Rhodium Plant LIFE experiment. The investigation studies how radiation and gravity environments at different orbital altitudes affect plant growth by comparing Crew-10 data with plants flown aboard the Polaris Dawn mission, which flew deeper into space. Studies have shown microgravity affects growth rates, and a better understanding of the mechanisms behind this could improve plant growth techniques in space and on Earth.
Solar spacewalk
NASA NASA astronaut Anne McClain conducts a spacewalk to upgrade the International Space Station’s power generation systems, which include main solar arrays like the one visible behind her. McClain is installing hardware to support an IROSA (International Space Station Roll-Out Solar Array), a type of array that is more compact and produces more power than the station’s original ones. The IROSAs were first demonstrated aboard the orbiting laboratory in June 2017, and eight have been installed to augment the power available for scientific research and other activities.
Microalgae on the menu
NASA NASA astronaut Nichole Ayers uses the International Space Station’s Space Automated Bioproduct Laboratory to process samples for SOPHONSTER, a study of microgravity’s effects on the protein yield of microalgae. These organisms are highly nutritious, producing amino acids, fatty acids, B vitamins, iron, and fiber. The microalgae could provide sustainable meat and dairy alternatives during long-duration space missions. It also could be used to make biofuels and bioactive compounds in medicines in space and on Earth.
Looking down on lightning
NASA The International Space Station orbits more than 250 miles above Earth, giving astronauts a unique view of their home planet, where they can photograph familiar places and interesting phenomena. While passing over a stormy night, NASA astronaut Nichole Ayers captured this image of simultaneous lightning at the top of two thunderstorms. Scientists use instruments installed on the space station to study lightning and other weather conditions in Earth’s upper atmosphere. This research helps protect communication systems and aircraft while improving atmospheric models and weather predictions.
Testing the tips of DNA

NASA In this time-lapse video, JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi and NASA astronaut Nichole Ayers harvest samples for the APEX-12 investigation, which examines how space radiation affects telomere activity in thale cress plants. Telomeres, which are repetitive DNA sequences that protect the ends of chromosomes, become shorter each time a cell divides and indicate cell aging. The APEX-12 investigation could clarify the role of telomeres in aging and diseases and help scientists equip plants and other organisms for the stress of long-duration spaceflight.
Microscopic motion
NASA A fluorescent microscope, known as ELVIS, captures the motion of microscopic algae and bacteria in 3D, a new capability aboard the International Space Station. The technology could be helpful in various applications in space and on Earth, such as monitoring water quality and detecting potentially infectious organisms. NASA astronaut Anne McClain prepares bacterial samples for viewing with the microscope.
How cells sense gravity
NASA Individual cells in our bodies can respond to the effects of gravity, but how they do this is largely unknown. The Cell Gravisensing investigation is an effort to observe the mechanism that enables cells to sense gravity and could lead to therapies to treat muscle and bone conditions, like muscle atrophy during long-duration spaceflight and osteoporosis on Earth. JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi processes research samples in the International Space Station’s Kibo laboratory module.
Water works
NASA NASA astronauts Nichole Ayers and Anne McClain work on installing hardware for the International Space Station’s Exploration Potable Water Dispenser. Scientists are evaluating the device’s water sanitization and microbial growth reduction technology. The dispenser provides room temperature and hot water for crew consumption and food preparation. This technology could be adopted for future exploration missions.
Free-flying camera
NASA Astronaut Takuya Onishi of JAXA (Japan Aerospace Exploration Agency) monitors the JEM Internal Ball Camera 2 as it floats through the International Space Station. The free-flying, rechargeable camera provides a visual field outside the other cameras installed aboard the space station. JAXA is testing the robot’s ability to capture video and imagery of scientific experiments and other activities, which could free up crew time for research and other duties.
Two rings to pin them all
NASA NASA astronaut Nichole Ayers sets up the space station’s Ring Sheared Drop device, which uses surface tension to pin a drop of liquid between two rings. The device makes it possible to study liquid proteins without a solid container, eliminating interactions between the solutions and container walls that can affect results. The Ring Sheared Drop-IBP-2 experiment studies the behavior of protein fluids in microgravity and tests predictive computer models. Better models could help advance manufacturing processes in space and on Earth for next-generation medicines to treat cancers and other diseases.
Crystallization research
NASA NASA astronaut Anne McClain swaps out hardware in the International Space Station’s Advanced Space Experiment Processor-4, which enables physical science and crystallization research. A current investigation uses the processor to demonstrate technology that may be able to produce medications during deep space missions and improve pharmaceutical manufacturing on Earth.
Monitoring astronaut health
NASA NASA astronaut Anne McClain helps JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi collect a sample of his blood. Analysis of blood samples is one tool NASA uses to continuously monitor crew health, including cardiovascular and immune system functions, bone and muscle mass changes, nutritional and metabolic status, and mental well-being. Crew members aboard the International Space Station also participate in various ongoing studies to better understand how different body systems adapt to weightlessness.
Catching a corona
NASA/KASI/INAF/CODEX This animated, color-coded heat map shows temperature changes in the Sun’s outer atmosphere, or corona, over several days, with red indicating hotter regions and purple showing cooler ones. Scientists can observe these changes thanks to the International Space Station’s CODEX, which collected data during the Crew-10 mission. The instrument uses a coronagraph to block out sunlight and reveal details in the Sun’s corona. Data from this investigation could help scientists understand the energy source of the solar wind, a flow of charged particles from the Sun that constantly bombards Earth.
Expanding in-space crystallization
NASA Astronaut Takuya Onishi of JAXA (Japan Aerospace Exploration Agency) services the International Space Station’s Advanced Space Experiment Processor-4 in preparation for ADSEP-Industrial Crystallization Cassette. This investigation tests new hardware that scales up research and could enable in-space production of pharmaceuticals and other materials for commercial space applications.
Sowing seeds in space
NASA NASA astronaut Nichole Ayers prepares mixture tubes containing samples for Nanoracks Module-9 Swiss Chard. This student-designed experiment examines whether the size, shape, color, and nutritional content of Swiss chard seeds germinated in space differ from those grown on Earth. The International Space Station hosts ongoing plant research as a source of food and other benefits, including contributing to astronaut well-being, for future long-duration missions.
Protecting astronaut vision
NASA Spaceflight can cause changes to eye structure and vision, so crew members monitor eye health throughout their missions. Astronaut Takuya Onishi of JAXA (Japan Aerospace Exploration Agency), assisted by NASA astronaut Nichole Ayers, conducts an eye exam aboard the International Space Station using optical coherence tomography. This technology uses reflected light to produce 3D images of the retina, nerve fibers, and other eye structures and layers.

Feeling the Heat: Perseverance Looks for Evidence of Contact Metamorphism
NASA’s Mars Perseverance rover acquired this image of the boulders along the contact at Westport, using its Mastcam-Z Left Camera, one of a pair of cameras located high on the rover’s mast. The rover acquired the image on July 10, 2025 — Sol 1560, or Martian day 1,560 of the Mars 2020 mission — at the local mean solar time of 11:23:38. NASA/JPL-Caltech/ASU Written by Melissa Rice, Professor of Planetary Science at Western Washington University
Following a short break for the July 4th holiday, Perseverance drove westward to a site called “Westport,” where the clay-bearing “Krokodillen” unit meets an olivine-bearing rock formation. It is possible that the olivine-rich rocks are an intrusive igneous unit, meaning they could have formed when molten magma from deep within Mars got pushed upwards and cooled under the surface. If that’s the case, Westport could preserve a dramatic moment in Mars’ history when hot, molten material intruded into existing rock formations.
Those intrusive processes are common on Earth, and the heat of the intruding magma can fundamentally alter the surrounding geology through a process called “contact metamorphism.” The heat from the intrusion will “bake” nearby rocks, creating new minerals and potentially new environments for microbial life. Conversely, the intrusive rocks get rapidly “chilled” where they meet preexisting solid rock formations.
At Westport, Perseverance is looking for evidence that the Krokodillen rocks at the contact were baked, and that the olivine-bearing rocks at the contact were chilled. Images from the Mastcam-Z instrument reveal that the contact is littered with intriguing dark, rubbly rocks alongside lighter-toned, smooth boulders. Both rock types are proving challenging to study.
The dark fragments are too small and rough for Perseverance’s standard abrasion techniques, but the rover cleared off the surface of a rock called “Holyrood Bay” with its gas Dust Removal Tool (gDRT). Perseverance also tried to abrade a nearby boulder named “Drake’s Point,” but the rock shifted to the side, causing the abrasion to stop short. The science questions here are compelling enough, however, that Perseverance will keep trying to look within the rocks at this important boundary.
