NASA today gave the final goahead for the 24 August launch of the Discovery (launch time was set for 0838 EDT) after engineers examined and tested six new heat sensors and certified them flight ready. 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.

Please, the word ''tube'' does not necessarily mean vacuum tube. The heat sensors in the main engines consist of some heat sensitive filaments housed in a tube. When these filaments melt, that sets the sensors off.
