The Challenger disaster occurred during mission STS-51-L, which was intended to deploy the Tracking and Data Relay Satellite (TDRS-2).

The cause of the accident was later determined to be the failure of an O-ring seal in one of the solid rocket boosters, which allowed hot gases to escape and ultimately led to the breakup of the spacecraft.
