However, reduction of the perceived threat and changing political priorities almost immediately caused the termination of most of these plans. Faget's preliminary Apollo design employed a cone-shaped command module, supported by one of several service modules providing propulsion and electrical power, sized appropriately for the space station, cislunar, and lunar landing missions.

The LM was to be left on the Moon and only the command module CM containing the three astronauts would eventually return to Earth. It was 33 feet NASA turned its attention to an Apollo-derived temporary space laboratory, and a semi-reusable Earth orbital shuttle. The X program employed mechanical techniques used in the later manned spaceflight programs, including reaction control system jets for controlling the orientation of a spacecraft, space suitsand horizon definition for navigation.
