KSC SPACE SHUTTLE PROCESSING REPORT - FRIDAY, NOV. 18, 1988 STS-27 - ATLANTIS (0V 104) - PAD 39-B Everything is proceeding on schedule at Launch Pad 39-B toward launch on Dec. 1. Technicians began servicing the orbiter's auxiliary power units (APUs) with fresh lube oil yesterday and are scheduled to complete the operation today. Later today, the APUs will be serviced with water in preparation for flight. Closeouts of the aft compartment are underway and testing of the inertial measurement units is scheduled. Sniff checks of the orbital maneuvering system (OMS) pods and the reaction control system are underway today. Over the weekend, technicians are scheduled to continue the aft closeouts and load the power reactant storage and distribution system (PRSD) dewars at the pad in preparation for loading the PRSD tanks with liquid oxygen and liquid hydrogen reactants during the launch countdown. STS-26 - DISCOVERY (OV 103) - OPF BAY 1 Orbiter systems testing is in work including checkout of the PRSD system and left OMS pod. The orbiter is scheduled to be powered down tonight for about 11 to 12 days while technicians replace the flash evaporator system. This system is one of several that provides heat radiation capability for the orbiter during various phases of flight. Some contamination was found in the system after an examination following the STS-26 flight. A few problems with the system were experienced during the flight. The system cannot be cleaned while in the orbiter. A new system is in shipment, ready to be installed over the next few weeks. STS-28 - COLUMBIA (OV 102) - OPF BAY 2 Orbiter modifications and power up testing to validate the electrical system are underway today. Technicians are also working on the orbiter's thermal protection system. STS-29 SOLID ROCKET BOOSTERS - VAB/RPSF The right aft booster and aft center segments were mated yesterday. The right forward center segment was moved into the transfer aisle and is being prepared for mating to the stack over the weekend. Next week, the left forward assembly is scheduled to be mated to the left booster.
