In just two-and-a-half years, beginning in 1964, two unmanned and ten manned flights took place in the Gemini program. This program was the turning point in the space race with the USSR; from then on the Americans took the lead. Flights lasting two weeks, into the Van Allen Belt, the first extravehicular activities, rendezvous maneuvers and docking with other spacecraft - all of this was achieved by Gemini, paving the way for the more demanding moon landing program. It was not all success, however. Like almost every significant undertaking, Project Gemini also had its dramas and tragedies. All Project Gemini missions are discussed, including details on allcraft and the astronauts involved. Superb color, archival images,cutaways and plans are also included.
