ABSTRACT
On re-entry the space shuttle Columbia destroy up in the hides atmosphere and disintegrated into a maelstrom of debris that stretched across alone most of Texas and Louisiana. At project foam dismission collision caused a corrupted structural integrity in the left-hand(a) wing. The disaster killed all crew members. This disaster occurred about 40 miles above the earths surface only a few proceeding before the shuttle was scheduled to land.
AUTHOR POV
The Columbia was an NASA artificial satellite in operation from 1981 to 2003. Upgrades were made during its lifecycle but much than 44% of its tiles and 41% of the 44 wing prima(p) edge panels were not replaced. The external tank was built by Lockheed Martin. The tank was coated with dense composite ablators to dissipate rage and low density closed-cell foams for high insulation efficiency. These materials were used to note oxygen and hydrogen in a liquid advance and to prevent ice and frost from forming on the surface.
During 79 missions the degradation of the foam was visible in 80% of cases. Foam was disconnected specifically from the left bipod ramp in 10% of missions when the left bipod ramp was visible after the tank had separated. In 30% of the missions foam loss couldnt be determined due to insufficient data.
It was not known why the foam loss occurred. Debris causes 143 divots to tiles during each flight on average. Majority of the divots were caused by external foam loss.
Mission STS-107 was scheduled to launch in 2001, but experienced 13 delays and actually launched in 2003. The launch was successful and experiments were done during the 16 day mission. Columbia plotted re-entry on February 1, 2003. As Columbia re-entered the atmosphere it began to break asunder killing all on board.
An investigating board of seven-spot members was automatically convened to uncover the causes of the shuttle disaster. All materials at NASA and contractor sites were persevered as evidence. Fault tree analysis was used to evaluate...If you indigence to get a full essay, order it on our website: Ordercustompaper.com
