Cause of the Challenger Disaster
The Challenger disaster was caused by the failure of an O-ring seal in the right solid rocket booster. This failure was attributed to a combination of factors, including the unusually cold weather on the day of the launch, which affected the elasticity of the O-ring material. The faulty seal allowed hot gases to escape, ultimately leading to the catastrophic disintegration of the shuttle.
According to the Rogers Commission, which investigated the disaster, organizational and communication issues within NASA also played a significant role. Engineers had raised concerns about the O-ring design prior to the launch, but their warnings were not adequately addressed.
