The Gemini program defined and tested the skills NASA would need to go to the Moon. The four objectives of Gemini, which spanned from 1961 to 1966, were to test an astronaut's ability to fly long-duration missions (up to two weeks in space), to understand how spacecraft could rendezvous and dock in orbit around the Earth and the Moon, to perfect re-entry and landing methods, and to further understand the effects of longer space flights on astronauts.

The Gemini galleries below have been separated by mission number, and each mission contains one or more cameras. Some of the missions used multiple cameras for experiments and documentation, and each camera has its own gallery. Select a gallery below to get started.
