Gemini 6 & 7 Rendezvous

Two spacecraft meeting in orbit require exact launch times and careful maneuvering. Gemini capsules 6 and 7 came within 30 centimeters of each other on Dec. 15, 1965. Frank Borman and James Lovell spent more than 13 days onboard Gemini 7, to set a record for long-duration flight.
