Shuttle is GO for Launch

From NASA Discovery is a "Go" for Launch Today's countdown was given a "go" last night by the Mission Management Team following analysis of an area of cracked insulation foam spotted on an upper section of the external tank. During a routine inspection Sunday night after the draining of the external fuel tank, a crack was discovered in the foam near a bracket that holds the liquid oxygen feedline in place. Extensive inspection showed that the area around the crack is intact and there is no concern for overheating around the bracket, as there is adequate foam still in place around the strut. Additional borescope inspection of the tank revealed that the metal bracket itself has no cracks.
