KSC SPACE SHUTTLE PROCESSING REPORT - THURSDAY, JULY 6, 1989 STS-28 - COLUMBIA (OV 102) - VAB Technicians are continuing to connect the orbiter to the external tank and launch platform. Both liquid hydrogen and oxygen tail service masts have been connected Columbia. Some alignment problems have been encountered in mating the tank-to-orbiter liquid oxygen electrical connector which is located next to the 17-inch disconnect line. Technicians will make another attempt to mate that electrical connector again today. Tile step and gap measurements will be taken around the nose of the orbiter, gap fillers will be installed in various areas and tile repairs will be made. The Shuttle Interface Test is scheduled to begin no earlier than tomorrow at midnight. The purpose of the test is to verify all critical connections between the orbiter and the tank, orbiter and boosters, orbiter and mobile launcher platform and to perform a functional operation check of the solid rocket boosters' systems. Columbia's rollout is currently targeted for no earlier than 12:01 a.m. Wednesday, July 12. STS-34 - ATLANTIS (OV 104) - OPF BAY 2 Preparations are underway to install the three main engines this week. Two of the engines are scheduled to be installed today and the third engine is slated for tomorrow. Preparations are underway to remove the left orbital maneuvering system pod this weekend. Operations continuing today include a leak test of the environmental control system, a functional check of the waste containment system and check out of the forward reaction control system. STS-33 - DISCOVERY (OV 103) - OMRF Power down work is continuing this week in the OMRF to prepare Discovery for transfer to OPF bay 1 on Monday. Preventative maintenance is being performed on equipment used in bay 1, including the telescoping buckets used for access to the payload bay. STS-34 SOLID ROCKET BOOSTERS - VAB/RPSF Stacking operations are continuing on a non-interference basis to shuttle mating activities. The left forward assembly is scheduled to be stacked today and joint closeouts are active.
