Space pioneer John W. Young, a man who flew twice to the moon, walked on its surface and commanded the first Space Shuttle mission, is retiring. Young's achievements during his 42-year career at NASA are unmatched. He was the first human to fly in space six times and launch seven times, six times from Earth and once from the moon. He is the only astronaut to pilot four different types of spacecraft, flying in the Gemini, Apollo and Space Shuttle programs.
The photo collage above traces Young's career through his six missions. Top row, from left: Gemini 3, Gemini 10, Apollo 10. Bottom row, from left: Apollo 16, STS-1, STS-9.
