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.

NASA’s Apollo Samples, LRO Help Scientists Predict Moonquakes
This mosaic of the Taurus-Littrow valley was made using images from the Narrow Angle Cameras onboard NASA’s Lunar Reconnaissance Orbiter. The orbiter has been circling and studying the Moon since 2009. The ancient-lava-filled valley is cut by the Lee-Lincoln thrust fault, visible as a sinuous, white line extending from South Massif (mountain in the bottom left corner) to North Massif (mountain in the top center) where the fault abruptly changes direction and cuts along the slope of North Massif. The Lee-Lincoln fault has been the source of multiple strong moonquakes causing landslides and boulder falls on both North and South massifs. The approximate location of the Apollo 17 landing site is indicated to the right of the fault with a white “x”. NASA/ASU/Smithsonian As NASA prepares to send astronauts to the surface of the Moon’s south polar region for the first time ever during the Artemis III mission, scientists are working on methods to determine the frequency of moonquakes along active faults there.
Faults are cracks in the Moon’s crust that indicate that the Moon is slowly shrinking as its interior cools over time. The contraction from shrinking causes the faults to move suddenly, which generates quakes. Between 1969 and 1977, a network of seismometers deployed by Apollo astronauts on the Moon’s surface recorded thousands of vibrations from moonquakes.
Moonquakes are rare, with the most powerful ones, about magnitude 5.0, occurring near the surface. These types of quakes are much weaker than powerful quakes on Earth (magnitude 7.0 or higher), posing little risk to astronauts during a mission lasting just a few days. But their effects on longer-term lunar surface assets could be significant. Unlike an earthquake that lasts for tens of seconds to minutes, a moonquake can last for hours, enough time to damage or tip over structures, destabilize launch vehicles on the surface, or interrupt surface operations.
“The hazard probability goes way up depending on how close your infrastructure is to an active fault,” said Thomas Watters, senior scientist emeritus at the Smithsonian’s National Air & Space Museum in Washington.
Watters is a long-time researcher of lunar geology and a co-investigator on NASA’s LRO (Lunar Reconnaissance Orbiter) camera. Recently, he and Nicholas Schmerr, a planetary seismologist at the University of Maryland in College Park, developed a new method for estimating the magnitude of seismic shaking by analyzing evidence of dislodged boulders and landslides in an area, as the scientists reported on July 30 in the journal Science Advances. Studies like these can help NASA plan lunar surface assets in safer locations.
Unlike an earthquake that lasts for tens of seconds to minutes, a moonquake can last for hours, enough time to damage or tip over structures, destabilize launch vehicles on the surface, or interrupt surface operations.
There are thousands of faults across the Moon that may still be active and producing quakes. Watters and his team have identified these faults by analyzing data from LRO, which has been circling the Moon since 2009, mapping the surface and taking pictures, providing unprecedented detail of features like faults, boulders, and landslides.
For this study, Watters and Schmerr chose to analyze surface changes from quakes generated by the Lee-Lincoln fault in the Taurus-Littrow valley. NASA’s Apollo 17 astronauts, who landed about 4 miles west of the fault on Dec. 11, 1972, explored the area around the fault during their mission.
By studying boulder falls and a landslide likely dislodged by ground shaking near Lee Lincoln, Watters and Schmerr estimated that a magnitude 3.0 moonquake — similar to a relatively minor earthquake — occurs along the Lee Lincoln fault about every 5.6 million years.
“One of the things we’re learning from the Lee-Lincoln fault is that many similar faults have likely had multiple quakes spread out over millions of years,” Schmerr said. “This means that they are potentially still active today and may keep generating more moonquakes in the future.”
The authors chose to study the Lee-Lincoln fault because it offered a unique advantage: Apollo 17 astronauts brought back samples of boulders from the area. By studying these samples in labs, scientists were able to measure changes in the boulders’ chemistry caused by exposure to cosmic radiation over time (the boulder surface is freshly exposed after breaking off a larger rock that would have otherwise shielded it).
This cosmic radiation exposure information helped the researchers determine how long the boulders had been sitting in their current locations, which in turn helped inform the estimate of possible timing and frequency of quakes along the Lee-Lincoln fault.
This 1972 image shows Apollo 17 astronaut Harrison H. Schmitt sampling a boulder at the base of North Massif in the Taurus-Littrow valley on the Moon. This large boulder is believed to have been dislodged by a strong moonquake that occurred about 28.5 million years ago. The source of the quake was likely a seismic event along the Lee-Lincoln fault. The picture was taken by astronaut Eugene A. Cernan, Apollo 17 commander. NASA/JSC/ASU Apollo 17 astronauts investigated the boulders at the bases of two mountains in the valley. The tracks left behind indicated that the boulders may have rolled downhill after being shaken loose during a moonquake on the fault. Using the size of each boulder, Watters and Schmerr estimated how hard the ground shaking would have been and the magnitude of the quake that would have caused the boulders to break free.
The team also estimated the seismic shaking and quake magnitude that would be needed to trigger the large landslide that sent material rushing across the valley floor, suggesting that this incident caused the rupture event that formed the Lee-Lincoln fault.

The label “A17” marks the Apollo 17 landing site. The audio represents a moonquake that was recorded by a seismometer placed on the surface by astronauts. The seismic signal is converted into sound. Both audio and video are sped up to play 10 times faster than normal. The background image is a globe mosaic image from NASA’s Lunar Reconnaissance Orbiter’s Wide-Angle Camera. Red and blue are positive (upward ground motion) and negative (downward ground motion) polarities of the wave. Nicholas Schmerr Taking all these factors into account, Watters and Schmerr estimated that the chances that a quake would have shaken the Taurus-Littrow valley on any given day while the Apollo 17 astronauts were there are 1 in 20 million, the authors noted.
Their findings from the Lee-Lincoln fault are just the beginning. Watters and Schmerr now plan to use their new technique to analyze quake frequency at faults in the Moon’s south polar region, where NASA plans to explore.
NASA also is planning to send more seismometers to the Moon. First, the Farside Seismic Suite will deliver two sensitive seismometers to Schrödinger basin on the far side of the Moon onboard a lunar lander as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative. Additionally, NASA is developing a payload, called the Lunar Environment Monitoring Station, for potential flight on NASA’s Artemis III mission to the South Pole region. Co-led by Schmerr, the payload will assess seismic risks for future human and robotic missions to the region.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The Research Aircraft for electric Vertical takeoff and landing Enabling techNologies Subscale Wind Tunnel and Flight Test undergoes a free flight test on the City Environment Range Testing for Autonomous Integrated Navigation range at NASA’s Langley Research Center in Hampton, Virginia on April 22, 2025.NASA/Rob Lorkiewicz Flying the friendly skies may one day include time-saving trips in air taxis to get from point A to point B – and NASA researchers are currently working to make that future a reality.
They are using wind tunnel and flight tests to gather data on an electric Vertical takeoff and landing (eVTOL) scaled-down small aircraft that resembles an air taxi that aircraft manufacturers can use for their own designs.
As air taxis take to the skies, engineers need real-world data on air taxi designs to better understand flight dynamics and design better flight control systems. These systems help stabilize and guide the motion of an aircraft while in flight, making sure it flies safely in various conditions.
Currently, most companies developing air taxis keep the information about how their aircraft behaves internal, so NASA is using this small aircraft to produce public, non-proprietary data available to all.
“NASA’s ability to perform high-risk flight research for increasingly automated and autonomous aircraft is really important,” said Siena Whiteside, who leads the Research Aircraft for eVTOL Enabling techNologies (RAVEN) project. “As we investigate these types of vehicles, we need to be able push the aircraft to its limits and understand what happens when an unforeseen event occurs…”
For example, Whiteside said, “…when a motor stops working. NASA is willing to take that risk and publish the data so that everyone can benefit from it.”

By using a smaller version of a full-sized aircraft called the RAVEN Subscale Wind Tunnel and Flight Test (RAVEN SWFT) vehicle, NASA is able to conduct its tests in a fast and cost-effective manner.
The small aircraft weighs 38 pounds with a wingspan of six feet and has 24 independently moving components.
Each component, called a “control effector,” can move during flight to change the aircraft’s motion – making it an ideal aircraft for advanced flight controls and autonomous flight research.
The testing is ongoing at NASA’s Langley Research Center in Hampton, Virginia.
Researchers first used the center’s 12-Foot Low-Speed Tunnel in 2024 and have since moved on to flight testing the small aircraft, piloting it remotely from the ground. During initial flight tests, the aircraft flew while tied to a tether. Now, the team performs free flights.
Lessons learned from the aircraft’s behavior in the wind tunnel helped to reduce risks during flight tests. In the wind tunnel, researchers performed tests that closely mirror the motion of real flight.
While the scale aircraft was in motion, researchers collected information about its flight characteristics, greatly accelerating the time from design to flight.
The team also could refine the aircraft’s computer control code in real time and upload software changes to it in under 5 minutes, saving them weeks and increasing the amount of data collected.

Bowman Partners in Research
NASA developed the custom flight controls software for RAVEN SWFT using tools from the company MathWorks.
NASA and MathWorks are partners under a Space Act Agreement to accelerate the design and testing of flight control approaches on RAVEN SWFT, which can apply to future novel aircraft.
The work has allowed NASA’s researchers to develop new methods to reduce the time for an aircraft to achieve its first flight and become a finished product.
RAVEN SWFT serves as a steppingstone to support the development of a potential larger, 1,000 pound-class RAVEN aircraft that will resemble an air taxi.
This larger RAVEN aircraft is being designed in collaboration with Georgia Institute of Technology and also would serve as an acoustical research tool, helping engineers understand the noise air taxi-like aircraft create.
The larger aircraft would allow NASA to continue to collect data and share it openly.
By performing flight research and making its data publicly available, NASA aims to advance U.S. leadership in technology development for safe, quiet, and affordable advanced air mobility operations.

Credit: NASA U.S. Transportation Secretary and acting NASA Administrator Sean Duffy joined President Donald J. Trump at the White House Wednesday for the historic signing of the Executive Order (EO), “Enabling Competition in the Commercial Space Industry.”
“People think the Department of Transportation (DOT) is just planes, trains, and automobiles – but we have a critical role to play in unlocking the final frontier. By slashing red tape tying up spaceport construction, streamlining launch licenses so they can occur at scale, and creating high-level space positions in government, we can unleash the next wave of innovation. At NASA, this means continuing to work with commercial space companies and improving our spaceports’ ability to launch,” said Duffy. “Thanks to the leadership of President Trump, we will enable American space competitiveness and superiority for decades to come. I look forward to leveraging my dual role at DOT and NASA to make this dream a reality.”
The EO will enable a competitive launch marketplace and substantially increase commercial space launch cadence and novel space activities by 2030.
“The FAA strongly supports President Trump’s Executive Order to make sure the U.S. leads the growing space economy and continues to lead the world in space transportation and innovation,” said FAA Administrator Bryan Bedford. “This order safely removes regulatory barriers so that U.S. companies can dominate commercial space activities.”
Executive Order highlights:
The “Enabling Competition in the Commercial Space Industry” EO will help to:
Streamline commercial license and permit approvals for United States-based operators. This includes eliminating regulatory barriers and expediting environmental reviews for commercial launches and reentries. Cut unnecessary red tape to make it easier to build new spaceports in the U.S. where more commercial space operations will be launched from. To ensure this Next Generation Spaceport Infrastructure, duplicate review process will be eliminated, and environmental reviews will be expedited. Promote new space activities like in-space manufacturing and orbital refueling through a streamlined framework. Expediting and streamlining authorization for this Novel Space Activity is essential to American space competitiveness and superiority. Establish a new position in the Office of the Secretary with the responsibility of advising the Secretary of Transportation on fostering innovation and deregulation in the commercial space industry. The FAA’s associate administrator for Commercial Space Transportation also will be a senior executive non-career employee, and the Office of Space Commerce will be elevated into the Office of the Commerce Secretary. Mitigate the risk of the United States losing its competitive edge in the commercial space industry by dismantling regulatory barriers that prevent rapid innovation and expansion.
