KSC SPACE SHUTTLE PROCESSING REPORT FOR - Tuesday, July 12, 1988 STS-26 - DISCOVERY (OV 103) - VAB Loading of the oxidizer, nitrogen tetroxide, into Discovery's Orbital Manuevering System pods and reaction control system was completed yesterday. Today workers are scheduled to load the fuel, monomethyl hydrazine, into Discovery's tanks. Two of the three auxiliary power units have been serviced with hydrazine and the third will be serviced today. The job is estimated to be completed by this evening. Later this week, workers will be performing a fit check of the crew escape pole in Discovery's crew module. Also preparations for the Flight Readiness Firing will commence when the pad reopens for normal work. The 20-second test firing of Discovery's main engines is scheduled for Monday, July 25 at 7:30 a.m. The FRF will be preceded by the "wet" tanking test scheduled for July 22 at 7 a.m. For both tests the external tank will be filled with its flight load of a half a million gallons of liquid hydrogen and liquid oxygen. After each test the external tank will be drained. STS-27 - ATLANTIS (0V 104) - OPF BAY 2 The last two helium tanks for the main propulsion system were installed yesterday. A systems test of the power reactant storage and distribution system is going well this week. Installation of the chin panel for flight is scheduled for today. A leak and functional test of the auxiliary power units is planned for this weekend. Thermal protection system operations are ongoing along with orbiter modifications. STS-28 - COLUMBIA (OV 102) - OMRF Access platforms have been positioned around the shuttle and orbiter modifications scheduled today include crew escape, thermal protection system operations and RTV heat sink. STS-26 SOLID ROCKET BOOSTERS - RPSF The right aft booster was mated to its aft skirt yesterday and an inspection of the case is underway today. Also in the RPSF, "build up" operations are continuing on the left aft booster. The external tank attach ring has been installed and foaming is scheduled today. Mobile Launcher Platform 1 will be moved into VAB high bay 3 in preparation for the stacking operation scheduled to begin the end of this month.
