Gemini XII was the tenth and final crewed flight of the Gemini series, which bridged the Mercury and Apollo programs. This mission, carrying astronauts Jim Lovell and Edwin "Buzz" Aldrin, was scheduled to perform rendezvous and docking with the Agena target vehicle, to conduct three Extravehicular Activity (EVA) operations, to conduct a tethered stationkeeping exercise, to perform docked maneuvers using the Agena propulsion system to change orbit, and demonstrate an automatic reentry. There were also 14 scientific, medical, and technological experiments on board.
