STS-1 Launch. NASA's first Space Shuttle, with an Orbiter named Columbia (Orbiter Vehicle 102), was finally ready for launch on April 10, 1981. The Commander was John Young, the most experienced astronaut, and the Pilot was Robert L. Crippen.
In the aftermath NASA's shuttle timetable was disrupted, and Columbia was not flown again until 1989 (on STS-28), after which it resumed normal service as part of the shuttle fleet. STS-93, launched on July 23, 1999, was the first U.S. space mission with a female commander, Lt. Col. Eileen Collins.
