アポロ司令・機械船
The Apollo lunar base proposal saw an uncrewed Saturn V used to land a shelter based on the Apollo Command/Service Module (CSM) on the Moon. A second Saturn V would carry a three-person crew and a modified CSM and Apollo Lunar Module (LM) to the Moon. The two-person excursion team would have a surface stay time of nearly 200 days and use of an advanced lunar rover and a lunar flier as well as logistics vehicles to construct a larger shelter. The isolation of the CSM pilot was a concern for mission planners, so proposals that it would be a three-person landing team or that the CSM would rendezvous with an orbiting module were considered.
