Gemini 6A (officially
Gemini VI-A) was a 1965 manned United States spaceflight in
NASA's
Gemini program. The mission achieved the first manned
rendezvous with another spacecraft, its sister
Gemini 7. Although the
Soviet Union had twice previously launched simultaneous pairs of
Vostok spacecraft, these established radio contact with, but came no closer than several kilometers of each other, while the Gemini 6 and 7 spacecraft came as close as one foot (30 cm) and could have docked had they been so equipped.
