PULLMAN, Wash – 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 NASA Artemis mission aims to land the first woman and first person of color on the moon in 2025 with the hope of eventually setting up a base camp there for further planetary exploration, so they are interested in finding a solution to the moon dust problem. The researchers are now working to fully understand and model the complex interactions between the dust particles and liquid nitrogen that allows the cleaning process to work
