Mission Overview
The Space Shuttle Challenger was NASA's second operational space shuttle, launched on its maiden voyage in April 1983. Over the course of its operational life, Challenger completed nine successful missions, contributing significantly to scientific research and space exploration. However, its tenth mission, STS-51-L, ended in tragedy.
The primary objective of STS-51-L was to deploy the second Tracking and Data Relay Satellite and conduct various scientific experiments. Additionally, the mission aimed to include the first-ever civilian teacher in space, Christa McAuliffe, as part of NASA's "Teacher in Space" program. This mission captured the imagination of millions around the world, making its failure all the more devastating.
