Gemini IX-A was the seventh crewed Earth-orbiting mission of the Gemini series. It carried astronauts Tom Stafford and Gene Cernan. Primary mission objectives were to demonstrate (1) rendezvous techniques and docking with a target vehicle to simulate maneuvers to be carried out on future Apollo missions, (2) an Extravehicular Activity (EVA) spacewalk to test the Astronaut Maneuvering Unit (AMU), and (3) precision landing capability. Scientific objectives included obtaining zodiacal light and airglow horizon photographs. Two micrometeorite studies were to be carried out, and there were also one medical and two technological experiments.
