Space Shuttle Challenger Disaster
On January 28, 1986, the Space Shuttle Challenger disintegrated just 73 seconds after liftoff, resulting in the tragic loss of all seven crew members on board.
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.
The Challenger disaster was a profound tragedy that had a lasting impact on NASA and the space exploration community, prompting significant changes to the space shuttle program and its safety protocols.
