The first orbit maneuver of lunar orbit insertion ( LOI ) must be implemented at the first perilune of the spacecraft flight to the moon. 月球捕获控制第一次制动必须在卫星飞向月球的第一近月点完成。
Dealing with the failure of the first maneuver the feasibility of lunar orbit insertion remedy maneuver is investigated and the requirement of the velocity is analyzed. 分析第一次近月制动失败后,继续进行月球捕获补救制动的可能性和能量要求。
