KSC SPACE SHUTTLE PROCESSING REPORT FOR - Thurs. Aug. 25, 1988 STS-26 - DISCOVERY (OV 103) - PAD 39-B Yesterday, workers completed pressurization of the Tracking and Data Relay Satellite. Currently underway are preparations to load hydrazine onboard the orbiter's auxiliary power units (APU) and on the solid rocket booster hydraulic power units (HPU). During the actual loading operation, the pad will be cleared of all non-essential personnel. Only those involved in the servicing will be at the pad wearing protective SCAPE suits. Five workers will be on the mobile launcher platform to service the HPUs and eight workers will be at the 107 ft. level of the Rotating Service Structure to load the APUs. After the hydrazine loading is complete tomorrow, workers will begin operations to install ordnance devices onboard the Interial Upper Stage. These are small explosive charges that will be used to separate the TDRS spacecraft from the IUS. STS-27 - ATLANTIS (0V 104) - OPF BAY 2 Activities scheduled today include: functional checkout of the waste containment system, potable water servicing, checkout of the water spray boilers, preparations to install the orbital maneuvering system pods, leak checks of the main propulsion system and thermal protection system operations. STS-28 - COLUMBIA (OV 102) - OPF BAY 1 Installation of the water lines around the crew hatch is scheduled along with structural inspections, thermal protection system operations and orbiter return-to-flight modifications. STS-27 SOLID ROCKET BOOSTERS - VAB/RPSF Preparations to mate the right forward center segment are continuing in the VAB transfer aisle. Joint closeouts are active on the left stack. Meanwhile, in the RPSF, workers are preparing the last solid motor segment for the STS-27 set, the right forward, for transfer to the VAB this weekend. The forward assemblies are scheduled to be mated to the boosters the first week of September. The external tank is scheduled to be mated to the boosters in mid-September.
