Case Study 12 The Challenger And Columbia Shuttle Disasters

Among them were the crew remains, which were identified with DNA. The Columbia Accident Investigation Board, or CAIB, as it was later known, later released a multi-volume report on how the shuttle was destroyed, and what led to it.Much later, in 2008, NASA released a crew survival report detailing the Columbia crew's last few minutes. Besides the physical cause – the foam – CAIB had a damning assessment about the culture at NASA that led to the foam problem and other safety issues being minimized over the years."Cultural traits and organizational practices detrimental to safety were allowed to develop," the board wrote, citing "reliance on past success as a substitute for sound engineering practices" and "organizational barriers that prevented effective communication of critical safety information" among the problems found.The astronauts probably survived the initial breakup of Columbia, but lost consciousness in seconds after the cabin lost pressure. In the weeks after the disaster, a dozen officials began sifting through the Columbia disaster, led by Harold W. CAIB recommended NASA ruthlessly seek and eliminate safety problems, such as the foam, to ensure astronaut safety in future missions.It also called for more predictable funding and political support for the agency, and added that the shuttle must be replaced with a new transportation system."The shuttle is now an aging system but still developmental in character.However, STS-107 stood apart as it emphasized pure research.

In July 2005, STS-114 lifted off and tested a suite of new procedures, including one where astronauts used cameras and a robotic arm to scan the shuttle's belly for broken tiles.Then, tire pressure readings from the left side of the shuttle also vanished.This image is a view of the underside of Columbia during its entry from mission STS-107 on Feb. This image was received by NASA as part of the Columbia accident investigation and is being analyzed.The Department of Defense was reportedly prepared to use its orbital spy cameras to get a closer look. 1, 2003, the shuttle made its usual landing approach to the Kennedy Space Center. EST, however, abnormal readings showed up at Mission Control.Temperature readings from sensors located on the left wing were lost.It was later found that a hole on the left wing allowed atmospheric gases to bleed into the shuttle as it went through its fiery re-entry, leading to the loss of the sensors and eventually, Columbia itself.Pieces of Columbia space shuttle debris are seen stored in a hangar at NASA's Kennedy Space Center in Florida during accident investigation in 2003. 1, 2003 shuttle disaster, which killed seven astronauts, were recovered.This image of the STS-107 shuttle Columbia crew in orbit was recovered from wreckage inside an undeveloped film canister.From left (bottom row): Kalpana Chawla, Rick Husband, Laurel Clark and Ilan Ramon.It is in the nation's interest to replace the shuttle as soon as possible," the report stated.NASA's space shuttle Columbia was destroyed during re-entry on Feb.
