KSC SPACE SHUTTLE PROCESSING REPORT - MONDAY, JUNE 19, 1989 STS-28 - COLUMBIA (OV 102) - OPF BAY 1 This past weekend, technicians replaced, for the second time, a seal between the main combustion chamber and the high pressure fuel turbopump on main engine number 1. Initial checks of the new seal are good, and leak tests are planned today. Installation of heat shields is scheduled to begin tonight pending the results of the leak test. A cabin leak test was successfully conducted last weekend. Functional tests of the landing gears were completed this past weekend. Preparations are underway for a positive pressure structural leak test today. Technicians are cleaning the payload bay and installing thermal blankets in the orbiter's midbody as part of orbiter closeout operations. Technicians are continuing to bond tiles with the cavity count this morning at 26. Eighteen of those cavities are on the payload bay doors. Columbia's target date for tow to the Vehicle Assembly Building is no earlier than June 30. While in the VAB, Columbia will be mated with its external tank and solid rocket boosters. STS-34 - ATLANTIS (OV 104) - OPF BAY 2 Checks of the power reactant storage and distribution system have been completed. This past weekend, the chin panel was replaced and the waste containment system (WCS) and the auxiliary power unit (APU) controllers were installed. Functional tests are planned this week for the WCS and the APUs. STS-33 - DISCOVERY (OV 103) - OMRF Power down work scheduled this week includes wiring and instrumentation improvements and modification of the crew seats to allow more room for the crew when they wear the partial pressure suits. Discovery will be transferred to bay 1 when Columbia is moved to the VAB. STS-28 SOLID ROCKET BOOSTERS - VAB Closeouts of the boosters and tank are underway in preparation for mating with the orbiter Columbia. STS-34 SOLID ROCKET BOOSTERS - VAB/RPSF The left aft center segment was mated with the left aft booster last night. The left forward center segment is scheduled to be transferred to the Vehicle Assembly Building today and lifted tomorrow night. Meanwhile, technicians are readying other STS-34 segments in the RPSF.
