Hazard Avoidance Techniques in Chang'e-6 Lunar Far Side Soft Landing
摘要
Abstract
Soft landing on the far side of the moon involves complex terrain and requires a higher level of hazard avoidance capability than landing on the near side of the moon.Restricted by propellant and other factors,the Chang'e-6 lander adopt a different method from Chang'e-4 that raises the hazard avoidance altitude to expend its hazard avoidance capability.Instead,it combines part of the"pinpoint"landing technology with hazard-avoidance.The pinpoint landing method helps the lander avoid known large-size hazards through unidirectional range control in the main braking phase.And the rough-fine-relay hazard-avoidance strategy identifies and avoids small-size hazards unknown in advance during the flight process below the approach phase to ultimately realize a safe soft landing.The hazard avoidance scheme adopted by Chang'e-6 is a technological upgrade compared with the previous Chang'e se-ries landers,and was technologically verified in advance for the subsequent realization of a full-fledged pinpoint landing.关键词
