NASA’s RASSOR (Regolith Advanced Surface Systems Operations Robot) undergoes testing to extract simulated regolith, or the loose, fragmental material on the moon’s surface, inside of the Granular Mechanics and Regolith Operations Lab at the agency’s Kennedy Space Center in Florida on May 27. Ben Burdess, mechanical engineer at NASA Kennedy, observes RASSOR’s counterrotating drums digging up the lunar dust and creating a three-foot berm.
