Richard Feynman, the Challenger Disaster, and Software

On January 28th, 1986, Space Shuttle Challenger was launched at 11:38am on the 6-day STS-51-L missionDuring the first 3 seconds of liftoff the o-rings (o-shaped loops used to connect two cylinders) in the shuttle's right-hand solid rocket booster (SRB) failed As a result hot gases with temperatures above 5,000 °F leaked out of the booster, vaporized the o-rings, and damaged the SRB's joints.

The Space Shuttle Challenger Accident

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 aft field joint.

The evidence of previous issues with o-ring erosion and blow-by can be captured directly on the Cause Map The more time it takes for extrusion to occur, however, the greater the damage to the O-rings This brings us to the most immediate reason for the O-ring failure: the low temperatures at launch caused the O-rings to harden.

The primary O-ring was too cold to seal properly, the cold-stiffened heat resistant putty that protected the rubber O-rings from the fuel collapsed, and gases at over 5000°F burned past both O-rings across 70 degrees of arc Eight hundredths of a second after ignition, the shuttle lifted off.

In the case of the Challenger, the analytic process on the day before the accident was seriously deficient, in the sense that--in hindsight to be sure--the Challenger would not have been launched on that very cold day (which compromised the O-rings and caused the accident) if smarter engineering analysis and better decision-making had taken place.
