A team at NASA’s Kennedy Space Center in Florida tests small- and medium-sized bucket drums July 16, 2021, in the Granular Mechanics and Regolith Operations Lab’s “big bin” during prototype development for the pilot excavator, a robotic mission designed for lunar operations. The bucket drum excavated lunar regolith simulant. The Swamp Works team leveled and compacted the simulant before excavation as well as measured penetration during the excavator testing. Robotics engineers Jason Schuler and Austin Langton worked inside the bin, teaming up with software engineer Kurt Leucht, who worked just outside of it.
