John Glenn was an astronaut for over 38 years, from his selection as a NASA astronaut in 1959 until his retirement from the program in 1997. He flew on three space missions: Mercury-Atlas 6 in 1962, Space Shuttle Discovery in 1998, and he was part of the crew for STS-95. His contributions to space exploration and public service extended well beyond his time as an astronaut.
