NASA’s Perseverance rover landed on Mars in 2021 to search for signs of ancient microbial life and to help scientists understand the planet’s climate and geography. But another key objective is to pave the way for human exploration of Mars, and as part of that effort, the rover carries a set of five spacesuit material samples. Now, after those samples have endured four years of exposure on Mars’ dusty, radiation-soaked surface, scientists are beginning the next phase of studying them.
The end goal is to predict accurately the usable lifetime of a Mars spacesuit. What the agency learns about how the materials perform on Mars will inform the design of future spacesuits for the first astronauts on the red planet.
“This is one of the forward-looking aspects of the rover’s mission—no...
