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 SRB casings were made of 12.7 mm (0.50 in) thick steel and were much stronger than the orbiter and ET; thus, both SRBs survived the breakup of the Space Shuttle stack, even though the right SRB was still suffering the effects of the joint burn-through that had set the destruction of Challenger in motion.

With James R. Hansen, he co-authored the 2009 book Truth, Lies, and O-Rings: Inside the Space Shuttle Challenger Disaster. [5] McDonald donated his personal papers on the accident to Chapman University in 2016 [1] and expressed hope that they would assist in preventing the same mistakes from being made. [3]
During the ascent phase, 73 seconds after liftoff, the vehicle experienced a catastrophic structural failure resulting in the loss of crew and vehicle. The Rogers Commission later determined the cause of the accident to have been the failure of the primary and secondary (backup) O-ring seals on Challenger ' s right Solid Rocket Booster (SRB ...
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 ...
O-ring mounting for an ultra-high vacuum application. [11] Pressure distribution within the cross-section of the O-ring. The orange lines are hard surfaces, which apply high pressure. The fluid in the seams has lower pressure. The soft O-ring bridges the pressure over the seams. O-rings are available in various metric and inch standard sizes.
Stellantis tells owners of 2005–2010 Dodge Challenger, Charger, Magnum and Chrysler 300 cars to park them until they have replaced faulty Takata airbags.
