Neil Armstrong and Dave Scott made the first ever docking in space look easy. However, just a few minutes later and out of radio contact with Mission Control, they experienced NASA's first near-disaster in space.
Gemini 7 was a mission no one was really that keen to fly. The idea of having to spend two weeks crammed into a cabin no bigger than the front seats of a hatchback, unable to stand up or even move around and in extremely close proximity with another person, was really not very appealing. Unfortunately for Frank Borman and Jim Lovell, they were the unlucky duo selected to fly it.
NASA's hopes of landing on the Moon hinged on Gemini 6A's Wally Schirra and Tom Stafford proving that rendezvous with another spacecraft was possible. It took NASA three attempts to launch the astronauts, though, with one coming very close to disaster.
Sandwiched between two milestone American spaceflights, Gemini 5 is often overlooked. Gordo Cooper and Pete Conrad's flight was just as important though, even if Conrad described it as 'eight days in a garbage can'.
Jim McDivitt and Ed White had been friends for years even before joining NASA, and now they were entrusted with the flight of Gemini 4 and the completion of the first ever American spacewalk.
