Collection Item Summary:
This a field joint heater that NASA developed after the Space Shuttle Challenger accident in January 1986. Because of the unusually cold weather, an o-ring in the right solid rocket booster (SRB) failed to seal. Hot exhaust gas escaped through the joint and pentrated the external fuel tank, causing the sequence of events that culminated in the shuttle's destruction. To avoid future accidents, NASA required that all future flights be equipped with heaters of this type to protect the SRB o-rings and field joints during launch.
Transferred to NASM from Tayco Engineering Inc. to the Museum in 1994.
