With the advent of the Space Shuttle program in the early 1980s, the original structure of the launch pads were remodeled for the needs of the Space Shuttle. Pad 39A hosted all Space Shuttle launches until January 1986, when would become the first to launch from pad 39B during the ill-fated STS-51-L mission, which ended with the destruction of "Challenger" and the death of the mission's crew a minute into the flight.
