Former astronaut on lunar spacesuits: "I don't think they're great right now"
Crew members traveling to the lunar surface on NASA's Artemis missions should be gearing up for a grind. They will wear heavier spacesuits than those worn by the Apollo astronauts, and NASA will ask them to do more than the first Moonwalkers did more than 50 years ago.
The Moonwalking experience will amount to an "extreme physical event" for crews selected for the Artemis program's first lunar landings, a former NASA astronaut told a panel of researchers, physicians, and engineers convened by the National Academies.
Kate Rubins, who retired from the space agency last year, presented the committee with her views on the health risks for astronauts on lunar missions. She outlined the concerns NASA officials often talk about: radiation exposure, muscle and bone atrophy, reduced cardiovascular and immune function, and other adverse medical effects of spaceflight.
