Yee) Organization: NASA Ames Research Center, Moffett Field, CA Lines: 61 KSC SPACE SHUTTLE PROCESSING REPORT - MONDAY, SEPT. 25, 1989 STS-34 - ATLANTIS (OV 104) - PAD 39-B This weekend, workers successfully replaced a quick disconnect for auxiliary power unit number one. A leak was discovered at the disconnect when hydrazine was being loaded aboard the orbiter about two weeks ago. The disconnect is between the fill line and the APU 1 fuel tank in the orbiter's aft compartment. Early this morning, the payload bay doors were opened. Preparations are underway to perform a partial interface verification test to recertify electrical and data connections between the Galileo/Inertial Upper Stage with the shuttle and ground support systems. Today, workers will verify connections between the launch pad, orbiter and launch platform. Preparations are underway for the first part of ordnance operations. The pad will be cleared between midnight and 8 a.m. tomorrow for this activity. Wednesday, the power reactant storage and distribution system dewars at the launch pad will be filled with liquid hydrogen and liquid oxygen. Launch remains targeted for Oct. 12 at 1:29 p.m. Eastern Time. The official launch date will be set at the conclusion of the Flight Readiness Review scheduled for Oct. 2-3 here at KSC. STS-33 - DISCOVERY (OV 103) - OPF BAY 1 The payload bay is ready for cleaning operations with rollover to the Vehicle Assembly Building scheduled for less than two weeks away. Hydraulic operations are planned this week including a final cycle of the aerosurfaces and a brake anti-skid test. A flight pressurization test of the main propulsion system helium system is scheduled Thursday. Redundancy tests of the orbiter's systems were performed Saturday. STS-32 - COLUMBIA (OV 102) - OPF BAY 2 As a result of the inadvertant activation of the firex water deluge system yesterday, workers are conducting detailed inspections and assessments of all areas of Columbia today. Cleanup activities are also underway. An investigation board has been named to determine the cause of the incident. STS-33 SOLID ROCKET BOOSTERS - VAB Technicians are closing out the joints on the right and left boosters for flight. Preparations to mate the external tank are underway for first shift tomorrow. Alignment measurements were taken of the solid rocket boosters this weekend. STS-32 SOLID ROCKET BOOSTERS - VAB The left aft booster was stacked over the weekend and workers are connecting the umbilicals today. The left aft center segment is scheduled for stacking the end of the week.
