Erosion rate of lunar soil under a landing rocket, part 1: Identifying the rate-limiting physics

|
By L. Aronowitz, J. N. Israelachvili, P.S. Jackson, Sachana Sathyan
| ScienceDirect Verified
Introduction When a spacecraft uses rocket propulsion to land on the Moon or another body, the exhaust gas accelerates particulates to high speed (Roberts, 1963; Lane et al., 2010; Fontes et al., 2022), threatening the spacecraft and nearby hardware (Immer et al., 2011) while disturbing mission science. A lunar lander the size of the Apollo Lunar Module (LM) sends ejecta globally since the exospheric atmosphere is too thin to slow even the finest dust.
