NASA has begun a new campaign to study how rocket exhaust will disturb the Moon’s surface during landings. Engineers at NASA’s Langley Research Center are firing a plume simulator into lunar soil inside a 60-foot vacuum chamber, recreating the low-pressure environment expected during future missions. The work supports Artemis plans to return astronauts to the Moon beginning with Artemis IV in 2028 and could help protect landers, payloads, experiments and rovers from flying debris.
Each test lasts about six seconds and records crater formation, ejecta height and angle, particle distribution and the speed of blasted regolith. The first phase uses a non-burning ethane system producing up to 100 pounds of thrust; a later phase will use a 3D-printed hybrid rocket motor with roughly 35 pounds of thrust. NASA says the modular setup can eventually be adapted for Mars by changing the soil simulant, hardware and chamber pressure, providing data to improve landing models and astronaut safety.
