A short during liftoff of Space Shuttle Columbia in July was traced to a wire in the payload bay with damaged insulation. As a result of that problem, NASA decided to inspect much of the wiring in all four Space Shuttles and make repairs as required. Here a technician is examining the wires onboard orbiter Endeavour. The next Shuttle mission, STS-103, the Third Hubble Space Telescope Servicing Mission, is currently scheduled for launch no earlier than Nov. 19, 1999
