KSC SHUTTLE STATUS - FRIDAY JULY 6, 1990 11 a.m. STS-38 - ATLANTIS (OV 104) - LAUNCH PAD 39-A Yesterday, liquid leak checks of auxiliary power units 1 and 2 were performed and the test verified there were no internal seal leaks. Engineers are continuing to identify requirements for another tanking test at the pad as troubleshooting of the hydrogen leak continues. The test will likely be conducted the end of next week. More instrumentation around the 17-inch discon- nect will be installed for this next test. The configuration of the vehicle will be maintained until further direction from the team investigating the leak. STS-35 - COLUMBIA (OV 102) - OPF BAY 2 Technicians are continuing the foaming operations around the newly installed 17-inch disconnect. Leak checks are planned. Tests of the two 17-inch disconnects and seals used in the STS-35 tanking test are scheduled to begin today and continue through the weekend at the Rockwell plant in Downey, Calif. Am- bient leak checks are planned today and leak tests using liquid nitrogen and liquid hydrogen are scheduled to begin tomorrow. STS-41 - DISCOVERY (OV 103) - OPF BAY 1 Final hookups of the newly installed shuttle main engines are underway. Technicians are installing one of right hand radiators and testing the orbiter's systems today. Thermal protection system operations are underway on all areas of the vehicle. Tests are continuing on the two orbital maneuvering system pods and forward reaction control system at the Hypergolic Main- tenance Facility. Discovery is being prepared for the STS- 41/Ulysses flight, scheduled for launch in October. STS-41 SOLID ROCKET BOOSTERS - VAB The right forward center segment was lifted to the high bay today and will be pinned to the booster stack tomorrow. The right forward segment, the last motor segment, is scheduled to be transferred to the Vehicle Assembly Building tomorrow. Closeout operations of the boosters are scheduled.
