"Ambition never rests, not even for a man who has left his footsteps on the moon."
John W. Young (born September 24, 1930)
Astronaut John Young is the only person to have piloted in space four different classes of spacecraft: Gemini spacecraft, Apollo Command/Service Module, Apollo Lunar Module, and Space Shuttle. Young also drove the Lunar Roving Vehicle on the moon's surface. He was the first person to orbit the moon alone (during the Apollo 10 mission), and was the commander of the first Space Shuttle mission in April 1981.
