(09/23/1999) --- 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 technicians are examining, repairing and protecting the wires onboard orbiter Discovery as necessary. The next Shuttle mission, STS-103, the Third Hubble Space Telescope Servicing Mission, is currently scheduled for launch no earlier than Nov. 19, 1999
