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 O-rings were rubber rings designed to form a seal in the shuttle's solid rocket boosters, preventing the rockets' hot gas from escaping and damaging other parts of the vehicle. Feynman suspected that despite NASA's claims, the O-rings were unsuitable at low temperatures and lost their resilience when cold, thus failing to maintain a tight ...
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.
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 ...
Deeply affected by the loss of the Challenger astronauts, McDonald endeavored to reveal the truth about the pressures to stay on launch schedule that led to the tragedy. [4] He co-authored the 2009 book Truth, Lies, and O-Rings: Inside the Space Shuttle Challenger Disaster. [3]
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 ...
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 ...
A History Channel dive team found a twenty-foot segment of the 1986 Space Shuttle Challenger in the waters off the coast of Florida, NASA says. An exact location and the depth off Cape Canaveral ...
