KSC SPACE SHUTTLE PROCESSING REPORT FOR - Thurs. July 21, l988 STS-26 - DISCOVERY (OV 103) - Pad 39-B Preparations are continuing today to support the upcoming Flight Readiness Firing (FRF) simulation this weekend, the Wet Countdown Demonstration Test (WCDDT), and the FRF. Overnight, engineers and technicians completed work on a data bus connector. A checkout of the Space Shuttle Main Engine (SSME) cutoff cables was completed, as was an aft skirt purge. Other completed work includes the SSME sensor calibrations. Engineers, managers, and technicians continue to explore various options for repair of a vent line leak in the left-hand OMS pod reaction control system. Using a "think tank" approach, engineers have come up with several options that will require furthur study and analysis. Repair of the leak, which has been stabilized, is not required for FRF. STS-27 - ATLANTIS (OV 104) - OPF Bay 2 A potable water system check was successfully performed. KU-band testing was completed Wednesday. Hydraulics work and systems testing of the power reactant storage and distribution system is underway this week. A brief period of power-on testing was concluded. Workers also completed an auxiliary power unit leak function check in conjunction with the LPS. STS-28 - COLUMBIA (OV 102) - OPF Bay 1 Work continues on removing the nose cap to allow access for structural inspections. Preparations, including the final weight assessment, are underway to allow door opening by this weekend. Other work items include the removal of tiles from the left side of the verticle stabilizer to allow replacement with thermal blankets. STS-27 SOLID ROCKET BOOSTERS - RPSF Work continues on the left and right aft boosters in preparations for next month's scheduled stacking operations in the VAB. Operations to install girth gages are proceeding.
