KSC SPACE SHUTTLE PROCESSING REPORT - WEDNESDAY, APRIL 5, 1989 STS-30 - ATLANTIS (0V 104) - PAD 39-B The interface verification test of the Magellan payload was successfully completed ahead of schedule earlier today. The test verifies connections between the orbiter and the payload. The end-to-end test of the Magellan and Interial Upper Stage and ground stations is planned for Saturday. Yesterday, technicians replaced a seal on the last high pressure oxidizer turbo pump after a detailed inspection that was prompted by an unusual noise heard during the installation. The pump is now being bolted back into place allowing technicians to begin making over 30 connections necessary to complete the installation later this week. The Countdown Demonstration Test is scheduled to begin Thursday, April 6 and will culminate with a simulated engine cutoff at 11 a.m. Friday. The test serves as a dress rehearsal for the flight crew and launch team. STS-28 - COLUMBIA (OV 102) - OPF BAY 1 Orbiter systems testing is underway today including checkout of the forward reaction control system. Orbiter systems are being checked out as return-to-flight activities continue. Leak and functional testing of the auxiliary power units is scheduled this week. Thermal protection system operations are continuing. STS-33 DISCOVERY (OV 103) - OPF BAY 2 Technicians have removed two of the main engines and the last engine is being removed today. One of the engines will be sent back to Rocketdyne in Canoga Park, Calif. for repairs to a crack in its main comubustion chamber. Removal of the SHARE heat pipe is also scheduled to begin today. A systems test of the power reactant storage and distribution system is planned this week. STS-28 SOLID ROCKET BOOSTERS - VAB/RPSF The left aft booster was transferred from the RPSF to the VAB Monday and stacked on the mobile launcher platform. Technicians are hooking up electrical umbilicals to the booster today. The left aft center segment is scheduled to be transferred to the VAB transfer aisle today in preparation for stacking. Meanwhile, other segments are being prepared for stacking in the RPSF.
