Friday July 27, 1990 10:00 p.m. KSC Space Shuttle Processing Status Report ----------------------------------------------------------------- STS-35 -- Columbia (OV 102) - OPF Bay 2 Final inspections of the 17-inch liquid hydrogen disconnect continues today on the orbiter Columbia. Closeouts of the aft compartment and final checks of the main propulsion system are in work. Leak checks are being completed on the GOX flow control valve and technicians are working on the high point bleed quick disconnect. Columbia is expected to be ready for rollover to the Vehicle Assembly Building for mating with the external tank and solid rocket boosters first shift Tuesday. Rollout to Pad A is currently targeted for August 7. Columbia with the ASTRO-1 payload is now scheduled for flight in early September. STS-38 -- Atlantis (OV 104) - Launch Pad 39-A Engineers continue to work a roll back contingency plan for as early as Monday in case the tropical storm system in the Caribbean threatens Florida's east coast. Current predictions, however, show there will be no effects seen from the storm as it continues on a westwardly track. Call to stations for this contingency plan will occur this afternoon and the crawler transporter will be moved to the pad gate. Nominal plans call for roll back to occur August 6. A complete photo survey of the shuttle's liquid hydrogen umbilical was performed yesterday at the pad. Auxiliary power unit number three will be removed from the orbiter's aft compartment this weekend. SCAPE operations in preparation for this work will commence early Saturday morning. Also, the Orbital Maneuvering System pods helium tanks will be vented today. STS-41 -- Discovery (OV 103) - OPF Bay 1 Installation of Discovery's forward reaction control system will continue today with interface verification operations and pressurization of the manifold in work. The right hand OMS pod will be loaded aboard its transporter tonight at the Hypergolic Maintenance Facility and moved to the Orbiter Processing Facility for installation on the orbiter this weekend. RTG cooling flow and leak checks are in work. Aerosurface cycling operations are scheduled to begin later today.
