Launch Catch-Up — Research Announced October 26, 2026.
NASA said measurements from its Perseverance rover identified fine and ultrafine dust attached to materials on Mars, offering evidence that could inform protective equipment for future astronauts.
In an October 26 announcement, the agency described observations collected over 1,645 Martian days. The findings are scheduled for publication October 27 in the Proceedings of the National Academy of Sciences.
The team used the rover's PIXL instrument and material samples associated with SHERLOC, both carried to Mars for other mission purposes. Some measured particles were roughly 100 to 300 nanometers across.
NASA said the smallest particles remained attached through years of rover movement. Different materials attracted different particle sizes, with static electricity appearing to influence the pattern.
The agency said the results could inform spacesuit materials, habitat design and dust-removal methods. These are measurements relevant to future engineering work, rather than evidence that protective systems have already been fully validated for human Mars missions.
