KSC SPACE SHUTTLE PROCESSING REPORT - FRIDAY, JUNE 9, 1989 STS-28 - COLUMBIA (OV 102) - OPF BAY 1 A functional test of the external tank doors and a main propulsion system and main engine end-to-end test are underway. Workers are repairing a piece of ground support equipment, called a Thompson rail, necessary for removing and replacing the main engine liquid hydrogen turbo pump. The rail's shaft and gear failed during proof testing. New pieces will be fabricated for the rail. In the meantime, technicians are scheduled to replace the heat shields around main engine number 1 in preparation for a positive pressure structural leak check of the orbiter's aft compartment. After the rail is ready to support the pump replacement, officials will determine whether the operation will take place in the OPF or after the orbiter is vertical. The landing gears are being checked out for flight this week with a functional test planned for next week. Technicians are rigging the landing gear doors for a tight fit and smooth closure. Thermal protection system operations are continuing. Columbia's target date for tow to the Vehicle Assembly Building for mating with its external tank and solid rocket boosters is June 23. STS-30 - ATLANTIS (OV 104) - OPF BAY 2 Removal preparations are underway today for the right orbital maneuvering system pod. The pod will be transferred to the maintenance facility for repairs. Checkouts of the power reactant storage and distribution system are continuing. Testing of the communications system are underway. Leak and functional tests of the auxiliary power units is continuing. STS-33 - DISCOVERY (OV 103) - OMRF Power down work scheduled today includes 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 in June. STS-28 SOLID ROCKET BOOSTERS - VAB Closeouts of the boosters and tank are underway. Workers are installing closeout covers over cables. STS-34 SOLID ROCKET BOOSTERS - RPSF The left aft booster was transferred from the Rotation Processing and Surge Facility to the VAB transfer aisle yesterday. Stacking is scheduled to begin on Wednesday.
