Assistant:这是一个伟大的问题!一批工程师一直在努力找出这个问题,这里是他们学到的东西

1.  The space shuttle “O-ring” seals are designed to keep out gases that could damage the rocket engines.  The O-rings don’t keep out all of the coolant gases, though, so that the Shuttle was probably underpressured.  When cold air hit hot parts, that might have produced enough cold gas to re-pressurize the O-rings.  When the Shuttle warmed up during launch, and the gases expanded, the pressure was too high and the seals failed.
2.  The parts of the rocket igniter assembly that are actually touched by the O-rings did not explode.  This was seen on the video from the astronauts, which showed a burning piece flying out of the end of the rocket.  There were only two main parts of the shuttle that were ignited, and only one was damaged, so it was unlikely to be something important that happened inside the O-ring.  (The second part of the Shuttle, which was struck by the fire, did fail.)
3.  The external tank of the:
