KSC SPACE SHUTTLE PROCESSING REPORT - TUESDAY, JULY 11, 1989 STS-28 - COLUMBIA (OV 102) - VAB Overnight, technicians replaced the aft integrated electronics assembly on the right hand solid rocket booster. During the shuttle interface test (SIT) yesterday, the IEA was giving erroneous data. After troubleshooting, the problem was isolated to the right aft IEA. The IEA contains all the electronics for the booster. While the IEA was replaced, the SIT test was put on hold and is scheduled to pick back up today. Connections between the tank, boosters and launch platform will be verified during this test. Tile operations are continuing in parallel with the SIT. Columbia's rollout is currently targeted for no earlier than 12:01 a.m. Friday, July 14. The countdown dress rehearsal test (TCDT) with the STS-28 flight crew and launch team is scheduled to begin at 8 a.m. Monday, July 17 and will culminate with a simulated engine cutoff at 11 a.m. July 18. STS-34 - ATLANTIS (OV 104) - OPF BAY 2 Preparations are underway for testing the three main engines tonight. Heat shields are scheduled to be installed around the main engines later this week. Operations continuing today include a functional check of the waste containment system and structural inspections including x-rays. Preparations are underway to install two getaway canisters containing an experiment package called Shuttle Solar Backscatter Ultraviolet Scientific Payload (SSBUV). The experiment is designed to provide an accurate long term set of atmospheric ozone and solar irradiance data by checking the calibration of the ozone sounders on satellites. STS-33 - DISCOVERY (OV 103) - OMRF Discovery is scheduled to be transferred from the OMRF to OPF bay 1 today. Once in the OPF, technicians will establish access to the vehicle and power up testing is scheduled to begin next week. STS-34 SOLID ROCKET BOOSTERS - VAB/RPSF Stacking operations are continuing on a non-interference basis to the STS-28 shuttle mating activities. The right forward center segment is scheduled to be transferred to the VAB today for mating preparations. The mate will occur after the STS-28 vehicle rolls to the pad.
