Perseverance finds lung-penetrating dust on Mars, offering clues for crews

Over 1,645 Martian days, NASA's Perseverance rover measured fine and ultrafine dust clinging to spacesuit material samples it carries, including particles small enough to penetrate lungs and enter the bloodstream. The findings, published October 27 in PNAS, could guide spacesuit and habitat design, dust-removal methods and crew health standards for future human missions to Mars.
