The cause of the disaster was the failure of the primary and secondary O-ring seals in a joint in the shuttle's right solid rocket booster (SRB). The record-low temperatures on the morning of the launch had stiffened the rubber O-rings, reducing their ability to seal the joints.
The commission found that the immediate cause of the Challenger accident was a failure in the O-rings sealing the aft field joint on the right solid rocket booster, causing pressurized hot gases and eventually flame to "blow by" the O-ring and contact the adjacent external tank, causing structural failure. The failure of the O-rings was ...
The failure of an O-ring seal on the starboard Solid Rocket Booster (SRB) was determined to have caused the shuttle to break up in flight. Space Shuttle flights were suspended for 32 months while the O-rings and other hazards that could have destroyed the vehicle on following missions were addressed. Shuttle missions resumed in September 1988 ...
Today we remember the Space Shuttle Challenger disaster that occurred on January 28, 1986, when Space Shuttle Challenger broke apart 73 seconds into its flight.
STS-51-L was the twenty-fifth flight in the American Space Shuttle program, and marked the first time a civilian had flown aboard the Space Shuttle. The mission used Space Shuttle Challenger, which lifted off from launch pad 39B (LC-39B) on January 28, 1986, from Kennedy Space Center, Florida.
The Space Shuttle Challenger was destroyed 73 seconds after lift-off on STS-51-L at an altitude of 15 kilometers (49,000 ft). The investigation found that cold weather conditions caused an O-ring seal to fail, allowing hot gases from the shuttle's solid rocket booster (SRB) to impinge on the external propellant tank and booster strut. The strut ...
