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 ...
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. The disaster led to the deaths of ...
The mission ended in disaster following the destruction of Challenger 73 seconds after lift-off, because of the failure of an O-ring seals on Challenger ' s right solid rocket booster, which led to the rapid disintegration of the Space Shuttle stack from overwhelming aerodynamic pressures.
Roger Mark Boisjoly (/ ˌ b oʊ ʒ ə ˈ l eɪ / BOH-zhə-LAY; [2] April 25, 1938 – January 6, 2012) was an American mechanical engineer, fluid dynamicist, and an aerodynamicist.He is best known for having raised strenuous objections to the launch of the Space Shuttle Challenger months before the loss of the spacecraft and its crew in January 1986.
When the Challenger space shuttle exploded a little over a minute after its launch in 1986, it pierced the dreams of millions about who watched the tragedy unfold live on television. In ...
A large section of the destroyed space shuttle Challenger has been found buried in sand at the bottom of the Atlantic, more than three decades after the tragedy that killed a schoolteacher and six ...
