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 ...
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.
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 ...
Space Shuttle Challenger (OV-099) was a Space Shuttle orbiter manufactured by Rockwell International and operated by NASA.Named after the commanding ship of a nineteenth-century scientific expedition that traveled the world, Challenger was the second Space Shuttle orbiter to fly into space after Columbia, and launched on its maiden flight in April 1983.
