History of spaceflight
Project Gemini was NASA's second manned spaceflight program. The program ran from 1961 to 1966. The program pioneered the orbital maneuvers required for space rendezvous. Ed White became the first American to make an extravehicular activity (EVA, or "space walk"), on June 3, 1965, during Gemini 4. Gemini 6A and 7 accomplished the first space rendezvous on December 15, 1965. Gemini 8 achieved the first space docking with an unmanned Agena Target Vehicle on March 16, 1966. Gemini 8 was also the first US spacecraft to experience in-space critical failure endangering the lives of the crew.
