Full Description: On January 28, 1986, the Challenger space shuttle and her seven-member crew were lost when a ruptured O-ring in the right solid rocket booster caused an explosion soon after launch. This photograph, taken a few seconds after the accident, shows the main engines and solid rocket booster exhaust plumes entwined around a ball of ...
The amount of O-ring erosion was insufficient to prevent the O-ring from sealing, and investigators concluded that the soot between the O-rings resulted from non-uniform pressure at the time of ignition. [3]: 130 [6]: 39–42 The January 1985 launch of STS-51-C was the coldest Space Shuttle launch to date. The air temperature was 62 °F (17 °C ...
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 ...
Bruce Weaver, a Florida-based photographer who captured a definitive image of space shuttle Challenger breaking apart into plumes of smoke and fire after liftoff, has died. Working as a freelance ...
Typical O-ring and application. An O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, forming a seal at the interface.
Video from the tracking camera E-207 shot during the liftoff of Challenger (STS-51-L) which captured the SRB plume piercing the external tank. Playback speed is 50% real-time. This angle places a greater degree of emphasis on the SRB plume which set into motion the failure of the tank that would cause the loss of the shuttle and tank less than ...
The space agency confirmed Thursday that a 20-foot segment of the Challenger was discovered earlier this year off the Florida coast by divers who were searching for wreckage of missing World War ...
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.
