KSC SPACE SHUTTLE PROCESSING REPORT - MONDAY, NOV. 13, 1989 STS-33 - DISCOVERY (OV 103) - PAD 39-B Pre-launch activities completed this weekend included a hot fire of the solid rocket booster hydraulic power units, final ordnance operations, pressurizing the orbital maneuvering system and reaction control system tanks for flight and loading storage tanks on the launch tower with liquid oxygen and liquid hydrogen propellants. Closeouts of the aft compartment for flight will be resumed today. Purges of the external tank are scheduled today and final ordnance operations are planned to start Tuesday evening. Last Friday, checks of the regulators for the reaction control system were completed and the extravehicular mobility units, or spacesuits, were installed. On Friday, the launch countdown is scheduled to begin at 4 p.m. EST and the STS-33 flight crew will be arriving. Launch of mission STS-33 is scheduled for Monday, Nov. 20 during a four- hour launch period that begins at 6:30 p.m. EST. STS-36 - ATLANTIS (0V 104) - OPF BAY 1 Engines 2 and 3 were removed this weekend and removal of engine 1 is underway today. The engines will undergo post-flight checks in the VAB engine shop and several components will be replaced prior to their reinstallation. Deservicing of residual hypergolic propellants is planned this week. Checks of the main propulsion system and communications system are scheduled this week. STS-32 - COLUMBIA (OV 102) - OPF BAY 2 The payload bay doors were closed on Friday. Closeouts of the vehicle for the move to the Vehicle Assembly Building are underway. The landing gear struts are being pressurized for flight today. Weight and center of gravity operations are planned for tomorrow. The orbiter transporter will be used to transfer the orbiter from the OPF to the Vehicle Assembly Building at 12:01 a.m. November 16. STS-32 SOLID ROCKET BOOSTERS/EXTERNAL TANK - VAB Two hydraulic power units, one on each booster, were replaced this weekend. Those two units came from the same lot with the cracked housings and the replacement was a precaution. There are two HPUs on each booster which provide power to gimbal the nozzles in flight. Preparations for orbiter mate are underway. STS-36 SOLID ROCKET BOOSTERS - VAB Saturday, the left aft center segment was mated. The left forward center was transferred to the VAB and stacking preparations are underway. The right aft booster is being built up in the Rotation Processing and Surge Facility.
