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.”

Credit: NASA/Sara Lowthian-Hanna Using portable X-rays to improve health care in inaccessible areas is not new, with systems deployed to diagnose medical issues in places such as base camps in Nepal and remote villages in South Africa. 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.

To See the World in a Grain of Sand: Investigating Megaripples at ‘Kerrlaguna’
NASA’s Mars Perseverance rover acquired this image of inactive megaripples at “Kerrlaguna,” Perseverance’s latest target of exploration, on Aug. 13, 2025. The rover acquired the image using its Right Mastcam-Z camera, one of a pair of cameras located high on the rover’s mast, on Sol 1593 — or, Martian day 1,593 of the Mars 2020 mission — at the local mean solar time of 12:05:13. NASA/JPL-Caltech/ASU Written by Athanasios Klidaras, Ph.D. candidate at Purdue University
On Mars, the past is written in stone — but the present is written in sand. Last week, Perseverance explored inactive megaripples to learn more about the wind-driven processes that are reshaping the Martian landscape every day.
After wrapping up its investigation at the contact between clay and olivine-bearing rocks at “Westport,” Perseverance is journeying south once more. Previously, attempts were made to drive uphill to visit a new rock exposure called “Midtoya.” However, a combination of the steep slope and rubbly, rock-strewn soil made drive progress difficult, and after several attempts, the decision was made to return to smoother terrain. Thankfully, the effort wasn’t fruitless, as the rover was able to gather data on new spherule-rich rocks thought to have rolled downhill from “Midtoya,” including the witch hat or helmet-shaped rock “Horneflya,” which has attracted much online interest.
More recently, Perseverance explored a site called “Kerrlaguna” where the steep slopes give way to a field of megaripples: large windblown sand formations up to 1 meter (about 3 feet) tall. The science team chose to perform a mini-campaign to make a detailed study of these features. Why such interest? While often the rover’s attention is focused on studying processes in Mars’ distant past that are recorded in ancient rocks, we still have much to learn about the modern Martian environment.
Almost a decade ago, Perseverance’s forerunner Curiosity studied an active sand dune at “Namib Dune” on the floor of Gale crater, where it took a memorable selfie. However the smaller megaripples — and especially dusty, apparently no longer active ones like at “Kerrlaguna” — are also common across the surface of Mars. These older immobile features could teach us new insights about the role that wind and water play on the modern Martian surface.
After arriving near several of these inactive megaripples, Perseverance performed a series of measurements using its SuperCam, Mastcam-Z, and MEDA science instruments in order to characterize the surrounding environment, the size and chemistry of the sand grains, and any salty crusts that may have developed over time.
Besides furthering our understanding of the Martian environment, documenting these potential resources could help us prepare for the day when astronauts explore the Red Planet and need resources held within Martian soils to help them survive. It is hoped that this investigation at “Kerrlaguna” can provide a practice run for a more comprehensive campaign located at a more extensive field of larger bedforms at “Lac de Charmes,” further along the rover traverse.
