O-ring - Wikipedia

The failure of an O-ring seal was determined to be the cause of the Space Shuttle Challenger disaster on January 28, 1986. A crucial factor was cold weather prior to the launch. This was famously demonstrated on television by Caltech physics professor Richard Feynman, when he placed a small O-ring into ice-cold water, and subsequently showed its loss of flexibility before an investigative ...

The Space Shuttle Challenger Accident – Davinder Mahal

O-rings when they are cold do not move as quickly as ones that are warm. Therefore if the O-rings were nearly frozen in place during ignition, the gases burnt the O-rings and produced the black smoke. Challenger left the launch pad and headed for space. During flight the O-rings continued to not seal the joint, and the gases leaked through the ...

Challenger: A Management Failure

Although the Shuttle successfully made it through Max Q point, it was later found that this phase played an important role in the disaster. At 73 seconds Challenger broke apart over Atlantic Ocean. The disintegration began with the failure of an O-ring seal in the right Solid Rocket Booster (SRB) that let a plume of hot gases break through.

Challenger was destroyed due to a faulty O-ring seal in one of its booster rockets, allowing burning gas to escape. The rubber O-rings, of which there were a primary and secondary between each rocket segment, weren't supposed to be burned by the gases resulting from liftoff, but that's exactly what happened during the testing phase.

Challenger O-Ring Failure: Breaking One Cause into Causes

The loss of compression on the O-rings is caused by the flexing of the joint, also called rotation, which is due to the design of the joint. And the loss of compression is cause by O-ring being less malleable in colder temperatures. Both causal paths shown below were required for the Challenger disaster to occur.
