To help NASA and commercial partners better understand the science of lunar landings, specifically the hazards that may occur when a lander’s engine plumes blast away at lunar dust, soil, and rocks, a team at NASA’s Langley Research Center in Hampton, Virginia, has initiated a series of plume-surface interaction tests inside a massive 60-foot spherical vacuum chamber.
As NASA works to return humans to the Moon starting with Artemis IV in 2028 and develop a Moon Base, the tests will provide a trove of data for researchers to use to improve predictive models and influence the design of space hardware.
“This plume-surface interaction ground test is the most complex test of its kind to be undertaken in a vacuum chamber,” said Ashley Korzun, testing lead at NASA Langley. “If I’m in a spacecraft and I’m going to move all that regolith while landing, some of that’s going to hit my lander. Some of it’s going to go out toward other things — payloads, science experiments, eventually rovers and other assets. Understanding those physics is pivotal to ensuring crew safety and mission success.”
