KSC SPACE SHUTTLE PROCESSING REPORT FOR - Tuesday, July 19, 1988 STS-26 - DISCOVERY (OV 103) - PAD-39 B Engineers are continuing to monitor the leak rate in the left hand orbital maneuvering system pod at pad 39-B. The leak is stable and is not causing complications inside the pod. Preparations for the "Wet" tanking test and Flight Readiness Firing are underway. This week, technicians are busy closing out the aft compartment and performing the last few tests prior to next week's tests. Today a leak check of the external tank liquid hydrogen fill and drain quick disconnects are planned. Later today the power reactant storage and distribution system is scheduled to be purged in preparation for next week's tests. During the tests the PRSD tanks will be loaded with liquid hydrogen and liquid oxygen. The countdown for the Wet Countdown Demonstration Test (WCDDT) is targeted to begin at 11:30 p.m. Friday, July 22 with the T-0 planned for 7 a.m. Monday, July 25. The T-0 for the Flight Readiness Firing is targeted for 7:30 a.m. Thursday, July 28. STS-27 - ATLANTIS (0V 104) - OPF BAY 2 Preparations for checking out the orbiter's water spray boilers are underway. Systems testing of the power reactant storage and distribution system is underway. Instrumentation is being calibrated for the chin panel. Operations to prepare the forward reaction control system cavity for the installation later this week are active. Thermal blankets are being installed along with other thermal protection system operations. Orbiter modifications are continuing. STS-28 - COLUMBIA (OV 102) - OMRF The strongbacks have been attached to the payload bay doors in preparation for door opening later this week. This will allow access for workers to implement modifications to systems and components located inside the bay. Thermal protection system operations are continuing. The smaller white diced tile originally on Columbia are being replaced with larger thermal blankets like those on the other two orbiters. STS-27 SOLID ROCKET BOOSTERS - RPSF "Build up" operations are continuing on the left and right aft solid rocket boosters. A leak check of the right aft nozzle is scheduled today and preparations to install instrumentation and cables on the left aft booster are underway. Stacking is scheduled to begin with the left aft booster the end of this month in the Vehicle Assembly Building.
