The six were to be installed in the Discovery's main engines today. Meanwhile, NASA said that all three heat sensors that gave high readings during Challenger's ascent (the two in the main engine that cut off and one in another engine) were damaged during flight and gave false readings. The wires and tubes inside the sensors were not installed correctly and were damaged when exposed to the 1700 degree heat.
