Wednesday August 1, 1990 9:30 a.m. KSC Space Shuttle Processing Status Report ----------------------------------------------------------------- STS-35 -- Columbia (OV 102) - OPF Bay 2 Rollover of the orbiter Columbia from the Orbiter Processing Facility to the Vehicle Assembly Building remains targeted for early Thursday morning. Final seal installation on the 17-inch umbilicals should be completed by mid-day today. The orbiter transporter is scheduled to be positioned under the orbiter late this afternoon, followed by jack and level operations. Managers yesterday decided additional tests on the external tank 17-inch disconnect were not needed, thereby clearing the way for orbiter rollover. In the VAB, the orbiter will be mated to the external tank and prepared for rollout to pad A mid-next week. STS-38 -- Atlantis (OV 104) - Launch Pad 39-A Post-tanking operations were placed on hold late yesterday at Pad A as technicians began hypergolic deservicing of the OMS/RCS system at midnight last night. Hypergolic deservicing is expected to take approximately 24 hours to complete. Following this work, mapping work of the liquid hydrogen lines will begin again. Engineers will also continue their preparations to remove APU number three. Removal of the auxiliary power unit is scheduled for Thursday. Rollback of Atlantis to the Vehicle Assembly Building is based on Columbia's readiness for rollout to pad A. Rollback is currently targeted for Wednesday August 8. STS-41 -- Discovery (OV 103) - OPF Bay 1 Work is complete on the left hand OMS pod thermal barrier and the pod is back in position on the orbiter. The OMS/RCS redundant electrical circuit verification tests were conducted successfully yesterday and the payload bay doors have been closed for thermal tile work. Preparations for the installation of auxiliary power unit number two is underway. Installation is scheduled for this weekend. STS-41 -- ET/SRB - VAB High Bay 1 Lifting of the external tank for mating with the solid rocket boosters is currently underway. The ET should be soft mated by 3:00 this afternoon.
