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.

With this unique capability, RASSOR can traverse the rough surface to dig, load, haul, and dump regolith that could be used in construction or broken down into hydrogen, oxygen, or water, resources critical for sustaining human presence.

The opposing motion of the bucket drums helps RASSOR grip the surface in low-gravity environments like the Moon or Mars. With this unique capability, RASSOR can traverse the rough surface to dig, load, haul, and dump regolith that could be used in construction or broken down into hydrogen, oxygen, or water, resources critical for sustaining human presence. RASSOR represents an earlier generation technology that informed the development of NASA’s IPEx (In-Situ Resource Utilization Pilot Excavator), serving as a precursor and foundational platform for the advanced excavation systems and autonomous capabilities now being demonstrated by this Moon-mining robot.
The primary test objective was to prove the ability of a bucket drum excavator to build surface features out of regolith. Bucket drums will be used on NASA’s IPEx (In-Situ Resource Utilization Pilot Excavator).
