What was the fatal flaw that caused the Space Shuttle Challenger disaster?
In: 695
The Space Shuttle Challenger disaster, which occurred on January 28, 1986, was caused by the failure of an O-ring seal in one of the solid rocket boosters (SRBs). The O-rings, which were made of a material called elastomeric seal, were designed to seal the gap between the sections of the SRBs. However, due to the cold temperatures on the day of the launch, the O-ring material became stiff and lost its ability to properly seal the joint, allowing hot gases to escape and ultimately causing an explosion that led to the loss of all seven crew members on board.
In addition to the engineering failure, there were also administrative and management decisions that played a role in the disaster. Prior to the launch, engineers from the manufacturer of the SRBs, Morton Thiokol, raised concerns about the performance of the O-rings in cold weather and recommended against launching the shuttle. However, NASA management overruled the objections and decided to proceed with the launch. This decision was influenced by political pressure to maintain the schedule of shuttle launches, as well as a lack of effective communication and collaboration between NASA’s management and engineering teams, which led to a culture within NASA that did not prioritize safety and allowed for risks to be taken without proper consideration of the potential consequences. The Challenger disaster highlighted the importance of effective communication, collaboration, and prioritization of safety in complex engineering projects.
