The novel method could form a crucial part of NASA’s plans to establish a permanent human presence on the moon.

You may not know that lunar dust poses a real problem to NASA as it aims to establish a permanent crew presence on the moon with its upcoming Artemis missions.

Now, though, a new liquid nitrogen spray developed by Washington State University researchers was able to remove virtually all of the simulated moon dust from a space suit during tests, a press statement reveals.


Moondust is largely made of small particles that can damage spacesuits, machinery, and equipment. In future habitats, it may even pose a health risk by damaging astronauts’ lungs.
