Lunar regolith (aka. moondust) is a major hazard for missions heading to the moon. It’s everywhere on the surface—5 to 10 meters (~16.5 to 33 feet) in depth in some places—not to mention jagged and sticky. During the Apollo missions, astronauts learned how this dust adhered to everything, including their spacesuits. Worse, it would get tracked back into their lunar modules (LMs), where it stuck to surfaces and played havoc with electronics and mechanical equipment, and even led to long-term respiratory problems.
