Summary of rendezvous operations

One of the major objectives of the Gemini Program was to develop and to demonstrate
techniques for the rendezvous and docking of space vehicles. This objective is of vital
importance since rendezvous and docking is mandatory for success in many future
manned space-flight programs. For example, lunar orbital rendezvous has been selected as
the primary mode for the Apollo lunar-landing mission which requires one rendezvous
and two dockings. Other programs requiring rendezvous are planetary missions, manned
space stations, and unmanned satellite inspection and repair missions.
