A liquid nitrogen spray developed by Washington State University researchers can remove almost all of the simulated moon dust from a space suit, potentially solving what is a significant challenge for future moon-landing astronauts.
The sprayer removed more than 98% of moon dust simulant in a vacuum environment with minimal damage to spacesuits, performing better than any techniques that have been investigated previously. The researchers report on their work in the journal, Acta Astronautica.
While people have managed to put men on the moon, they haven’t figured out how to keep them clean there. Similar to the clingiest packaging peanuts, moon dust sticks to everything that it touches. Worse than the packing peanuts, the dust is composed of very fine particles that are the consistency of ground fiberglass.
