In bay 3 of the Orbiter Processing Facility, United Space Alliance technicians make final adjustments on space shuttle Discovery's starboard landing gear. The components were removed in order to replace a hydraulic seal in the right main-gear strut. Engineers determined an observed leak of hydraulic fluid in the main landing gear strut exceeded specification and could not be reduced to an acceptable rate. Thus, the leaky seal and three other seals were replaced. Prior to discovery of the leak, the vehicle had been scheduled to roll over Sept. 19 from the OPF to the Vehicle Assembly Building. A new rollover date will be set for Discovery, which is targeted for launch on Oct. 23. Photo credit: NASA/George Shelton
