KSC SPACE SHUTTLE PROCESSING REPORT FOR - Thurs. Sept. 22, 1988 STS-26 - DISCOVERY (OV 103) - PAD 39-B Tests of the newly installed actuator for the fuel pre- burner oxidizer valve on main engine number three are scheduled today. Also scheduled today are purges of the power reactant storage and distribution system tanks. These purges prepare the tanks for the liquid hydrogen and liquid oxygen loading operation during the launch countdown. After the tests mentioned above are completed later tonight, workers will finish closing out the aft compartment. Early tomorrow, purges of the external tank are scheduled to condition the lines and prepare it for the loading operation during the countdown. Batteries on the Tracking and Data Relay Satellite are being charged today and more testing of the Inertial Upper Stage is planned for tonight to validate data collected during yesterday's IUS countdown simulation. Other operations today include installation of heat shields around the main engines, a final inspection of the thermal blankets on the payload bay doors and launch countdown preparations. Final installation of ordnance devices on the payload and on the vehicle, and the follow up testing, are scheduled for Saturday. On Sunday, workers are scheduled to inspect the aft compartment and perform a structural leak test of the vehicle. All work leads up to the start of the launch countdown at 12:01 a.m. Monday, Sept. 26. The countdown clock will begin at the T-43 hour mark. The STS-26 flight crew is scheduled to arrive at KSC's Shuttle Landing Facility around 4:30 p.m. Monday to prepare for the launch. STS-27 - ATLANTIS (0V 104) - OPF BAY 2 Earlier today workers completed the frequency response test of the main engine valves. Later today, technicians will test the orbiter's aerosurfaces. Other activities scheduled today are inspections of the tire pressure instrumentation and waterproofing orbiter tiles. In addition, preparations for the Crew Equipment Interface Test (CEIT) are underway. Members of the STS-27 flight crew will participate in the test which is planned for the weekend. The test gives the flight crew a chance to become familiar with Atlantis' crew compartment configuration for this mission and any mission unique equipment. STS-28 - COLUMBIA (OV 102) - OPF BAY 1 Preparations are underway to support Columbia's power up tomorrow at 10 a.m. Inspections of the orbiter's airframe and thermal protection system operations are scheduled this week. STS-27 SOLID ROCKET BOOSTERS/EXTERNAL TANK - VAB The external tank was "hard" mated to the boosters yesterday and technicians are hooking up electrical connections and routing cables today. STS-29 SOLID ROCKET BOOSTERS - RPSF Technicians are "building" up the left aft booster to prepare the segment for stacking on the mobile launcher platform.
