Leroy Gordon "Gordo" Cooper's record-breaking spaceflight happened 46 years ago, on May 15 and 16, 1963. He made 22 orbits of the Earth in Mercury-Atlas 9, which he christened "Faith 7." During a flight that stretched over a day and a half, he became the first American to go to sleep in space. He also dealt with a plethora of issues, as the systems on his Mercury spacecraft, which were not designed for long-duration flight, began to break down.


Cooper's mission was considered a complete success. There was one Mercury spacecraft remaining, which Alan Shepard had hoped to fly - and had already dubbed Freedom 7 II. However, NASA decided to terminate the Mercury program and concentrate its efforts on Gemini and Apollo. Following Cooper's mission, it would be 22 months before the next Americans went into space.
