Analyses on mission operations and systems for lunar landing modules are conducted. The results of the review are presented. The main subjects of the review are as follows: (1) mission operation analyses (orbits); (2) attitudes; (3) methods of detecting the barrier at landing; (4) stability at landing; (5) system configurations, weight, and power balances; (6) main propulsion system thrust and speed increments; (7) weight and electric power analyses; (8) thermal analyses; (9) communication circuits; (10) payload interfaces; (11) on-ground systems; (12) assembly methods; and (13) subsystems. Sequences up to landing on the moon are introduced as follows: (1) launch to lunar transfer orbit; (2) mid-course maneuver; (3) entry into lunar gravity range; (4) deceleration before entering lunar rotating orbit; (5) getting on the lunar rotating orbit; (6) descending maneuvering to land on the moon; (7) getting on the lunar descending orbit; (8) throttling to hovering thrust; (9) hovering at an altitude of 100 km; and (10) stopping the engine to land on the moon at an altitude of several meters.
