Drew Smith, a robotics engineer, makes adjustments to the Regolith Advanced Surface Systems Operations Robot (RASSOR) during testing in the regolith bin inside Swamp Works at NASA’s Kennedy Space Center in Florida on June 5, 2019. Smith and other members of the Granular Mechanics and Regolith Operations Lab run tests, which simulates the Moon’s reduced gravity using the gravity assist offload system to see how RASSOR excavates regolith. On the surface of the Moon, mining robots like RASSOR will excavate the regolith and take the material to a processing plant where usable elements such as hydr…
