The Gemini spacecraft carried 20 astronauts into space from 1964-1966 in order to test the effects of prolonged exposure to space on astronauts and practice key maneuvers such as docking with another vessel in space and landing a spacecraft in water.  These were key mission objectives in order to prepare to send America to the Moon.
