First, free-return trajectories, which allow the outbound trip to the Moon to be aborted and the spacecraft returned to Earth with little additional propulsion requirement, are not compatible with injection into lunar polar orbit.

Basic landing-leg technology was developed for the lunar Surveyor and Apollo programs in the early 1960s. In conjunction with a variable-thrust liquid propulsion system and a closed-loop guidance and control system, legs represented an elegant solution to the touchdown problem. They are simple, reliable mechanisms that can be added to an integrated structure that houses the scientific and engineering subsystems for a typical surface mission (Figure 1).
