It was discovered
Christa McAuliffe to investigate the disaster. It determined that the accident was due to a failure of rubber O-rings made by Morton-Thiokol that provided a pressure seal in the aft field joint of the shuttle's right Solid Rocket Booster. The failure of the O-rings was attributed to a design flaw, as their performance could be too easily compromised by factors that included the low temperature on the day of launch. The Commission found that O-ring resiliency is directly related to temperature and due to the low temperature at launch—36 degrees Fahrenheit or 15 degrees lower than the next coldest previous launch—it was
