ALT NASA’s RASSOR (Regolith Advanced Surface Systems Operations Robot) conducts excavation testing of simulated regolith, or lunar dust found on the Moon’s surface, inside of the Granular Mechanics and Regolith Operations Lab at the agency’s Kennedy Space Center in Florida on Tuesday, May 27, 2025. RASSOR is designed to work in low-gravity situations, using counter rotating bucket drums on each arm to collect and dump regolith for the extraction of hydrogen, oxygen, or water, resources critical for sustaining a habitable presence.
