Perseverance dust measurements could guide future Mars crew protection
NASA says rover measurements of fine and ultrafine dust on material samples could inform spacesuit and habitat design for future Mars missions.
What the record says
NASA’s October 26 account describes measurements of fine and ultrafine Martian dust clinging to material samples aboard the Perseverance rover. Using the PIXL instrument and samples carried as calibration targets, researchers examined particles on Teflon and other surfaces. NASA says the findings could inform material choices, dust-removal methods and designs for future spacesuits and habitats. Its account notes that particle size and how strongly grains stick to different materials are relevant to controlling dust brought into living spaces. The agency said the findings were scheduled for publication in the Proceedings of the National Academy of Sciences on October 27.
