STS-51-L was the disastrous 25th mission of NASA's Space Shuttle program and the final flight of Space Shuttle Challenger. It was planned as the first Teacher in Space Project flight in addition to observing Halley's Comet for six days and performing a routine satellite deployment.
The SRB casings were made of 12.7 mm (0.50 in) thick steel and were much stronger than the orbiter and ET; thus, both SRBs survived the breakup of the Space Shuttle stack, even though the right SRB was still suffering the effects of the joint burn-through that had set the destruction of Challenger in motion.

The explosion of Space Shuttle Challenger, taken from the TV-3 camera. At T+72.284, the right SRB pulled away from the aft strut that attached it to the ET, causing lateral acceleration that was felt by the crew. At the same time, pressure in the LH2 tank began dropping. Pilot Mike Smith said "Uh-oh," which was the last crew comment recorded.
A second space shuttle disaster. Seventeen years after the Challenger disaster, another shuttle and its crew were lost in the skies above America: The shuttle Columbia broke apart upon reentry on ...
Space Shuttle Challenger breaks up during its 1986 launch resulting in the death of all seven crew members. This article lists verifiable spaceflight-related accidents and incidents resulting in human death or serious injury. These include incidents during flight or training for crewed space missions and testing, assembly, preparation, or ...
Feynman's investigation eventually suggested to him that the cause of the Challenger disaster was the very part to which NASA management so mistakenly assigned a safety factor. The O-rings were rubber rings designed to form a seal in the shuttle's solid rocket boosters, preventing the rockets' hot gas from escaping and damaging other parts of ...
