Preparations for Next Moonwalk Simulations Underway (and Underwater)

Crews will need non-invasive imaging technology to diagnose medical conditions, like broken bones or dental injuries.
Scientists at NASA’s Glenn Research Center in Cleveland are testing portable, handheld X-ray systems for use during future extended space missions. Having portable X-ray capabilities aboard spacecraft would allow astronauts to immediately assess and treat potential injuries or identify equipment issues without having to disassemble the gear.
“Technological innovations like that of the mini-X-ray will help keep our astronauts healthy as we endeavor farther into space than ever before,” said acting NASA Administrator Sean Duffy. “Future missions to the Moon and Mars will be safer due to the research of our scientists at NASA Glenn.”
NASA reviewed more than 200 commercial systems — analyzing size, weight, image quality, ease-of-use, cost, and safety — and selected three systems for further testing: MinXray, Remedi, and Fujifilm.
“We’re working to provide evidence on why a mini-X-ray system should be included in future space exploration,” said Dr. Chase Haddix, a senior biomedical engineering research contractor working for Universities Space Research Association at NASA Glenn. “These X-rays could be used to detect both clinical and non-clinical diagnostics, meaning they can check an astronaut’s body or identify the location of a tear in an astronaut suit.”

“We’re fortunate to have enthusiastic medical and radiography experts right here in our community,” said Dr. Cy Peverill, project task lead at NASA Glenn. “Their knowledge and experience are invaluable as we work to test medical technologies that could significantly improve management of astronaut health on future missions to the Moon or Mars.”
Cuyahoga Community College contributed anatomical phantoms, which are lifelike models of the human body, in its radiography laboratory on the Western Campus and dental hygiene clinical facility at the Metropolitan Campus. Faculty and students consulted with NASA researchers on essential imaging principles, including patient positioning, image acquisition, and image quality.
University Hospitals is partnering with NASA Glenn on a medical study with real patients to compare the performance of the X-ray systems against hospital-grade equipment, focusing on usability, image clarity, and diagnostic accuracy.
“Astronauts live and work in small quarters, much smaller spaces than in a hospital,” Haddix said. “The system must be easy to use since astronauts may not be experienced in radiography. The data from these tests will guide the selection of the most suitable system for future missions.”

NASA researchers theorize that if these systems are successful in high elevations and extreme temperatures on Earth, perhaps they are durable enough for space missions.
Glenn researchers will continue to collect data from all collaborators, including from an X-ray system sourced by SpaceX that launched in April during the Fram2 mission. The crew captured the first human X-ray images in space during their four-day mission to low Earth orbit. NASA plans to select a device near the end of 2025 and will test the chosen system aboard the International Space Station in 2026 or early 2027.
The Mars Campaign Office at NASA Headquarters in Washington and the agency’s Human Research Program at NASA Johnson fund this work as both organizations focus on pursuing technologies and methods to support safe, productive human space travel.

The next era of lunar exploration demands a new kind of wheel – one that can sprint across razor-sharp regolith, shrug off extremely cold nights, and keep a rover rolling day after lunar day. The Rock and Roll with NASA Challenge seeks that breakthrough. If you can imagine a lightweight, compliant wheel that stays tough at higher speeds while carrying lots of cargo, your ideas could set the pace for surface missions to follow. For this phased Challenge, Phase 1 rewards the best concepts and analyses, Phase 2 funds prototypes, and Phase 3 puts the best wheels through a live obstacle course simulating the lunar terrain. Along the way, you’ll receive feedback from NASA mobility engineers and the chance to see your hardware pushed to its limits. In Phase 3, to prove concepts, NASA is using MicroChariot, a nimble, 45 kg test rover that will test the best designs from Phase 1 & Phase 2 at the Johnson Space Center Rockyard in Houston, Texas. Whether you’re a student team, a garage inventor, or a seasoned aerospace firm, this is your opportunity to rewrite the playbook of planetary mobility and leave tread marks on the future of exploration. Follow the challenge, assemble your crew, and roll out a solution that takes humanity back to the Moon.
Award: $155,000 in total prizes
Open Date: Phase 1 – August 28, 2025; Phase 2 – January 2026; Phase 3 – May 2026
Close Date: Phase 1 – November 4, 2025; Phase 2 – April 2026; Phase 3 – June 2026

Amit KshatriyaCredit: NASA Acting NASA Administrator Sean P. Duffy Wednesday named Amit Kshatriya as the new associate administrator of NASA, the agency’s top civil service role.
A 20-year NASA veteran, Kshatriya was most recently the deputy in charge of the Moon to Mars Program in the Exploration Systems Development Mission Directorate (ESDMD) at NASA Headquarters in Washington. In this role, Kshatriya was responsible for program planning and implementation for crewed missions to the Moon through the Artemis campaign in preparation for humanity’s first mission to Mars.
Promoting Kshatriya to NASA’s top ranks puts America’s return to the Moon through Artemis at the very core of our agency. The move exemplifies President Donald J. Trump and Duffy’s seriousness about returning Americans to the Moon and before China.
“Amit has spent more than two decades as a dedicated public servant at NASA, working to advance American leadership in space. Under his leadership, the agency will chart a bold vision to return to the Moon during President Trump’s term,” said Duffy. “Amit’s knowledge, integrity, and unwavering commitment to pioneering a new era of exploration make him uniquely qualified to lead our agency as associate administrator. With Amit we’ll continue to push the boundaries of what’s possible.”
Kshatriya’s promotion also signals how the Trump Administration sees the commercial space sector as an American economic engine. By putting a proven leader at the top, NASA is set to partner even more closely with America’s booming space industry, grow the space economy, and ensure the future of exploration is built in the United States.
Born in Wisconsin, educated at California Institute of Technology and the University of Texas at Austin, Kshatriya is one of only about 100 people in history to serve as a mission control flight director. He brings unparalleled operational and strategic experience to NASA’s executive leadership team.
