Mechanisms of Ejecta Streak Formation During Spacecraft Landings on the Moon
When landing on another planetary body, spacecraft most often employ retropropulsion to decelerate for a soft landing. This process generates a crater and ejects high-speed particles, which can destabilize the lander and pose risks to nearby infrastructure. From the Apollo missions in the 1960s to the recent Chang'E-5 mission, particles leave the impingement region as streak filaments, regardless of landing site, lander mass, or thrust. This study aims to uncover the mechanism behind the formation of these ejecta streaks.
