Yee) Organization: NASA Ames Research Center, Moffett Field, CA Lines: 50 KSC SHUTTLE STATUS REPORT - TUESDAY, OCT. 2, 1990 10 AM STS-41 - DISCOVERY (OV 103) - PAD 39-B Overnight, technicians repaired a broken wire in the orbiter's aft compartment. This broken wire did not allow power to the main propulsion system engine 2 liquid oxygen prevalve. Electrical tests have been successfully conducted and the aft compartment was closed out for flight at about midnight last night. Closeouts of the right solid rocket booster aft skirt are continuing. The radioisotope thermoelectric generator was successfully installed today. The payload bay doors are scheduled to be closed for flight tomorrow morning. Launch countdown preparations are underway to pick up the count on time at 3:30 a.m. EDT tomorrow at the T-43 hour mark. Today, inspectors will make assessments of the launch pad as part of countdown preparations. Discovery and the Ulysses spacecraft are being prepared for liftoff at 7:35 a.m. EDT, Saturday Oct. 6. The STS-41 five-member flight crew is scheduled to arrive at KSC at 3:30 p.m. Wednesday. STS-35 - COLUMBIA (OV 102) - PAD 39-A Leak tests are continuing on the main propulsion system valves, actuators and areas of the recirculation pump package to try to isolate the source of the leak. The KSC team is working with a team of specialists assigned to find the fuel leak. This week, baggies will be installed over certain joints and the main propulsion system will be pressurized with gaseous helium. Any leakage will be monitored. Columbia is scheduled to be moved to Launch Pad 39-B Monday, Oct. 8 with first motion at 4 a.m. Details and requirements are being identified for a tanking test to be conducted after the STS-41 launch. STS-38 - ATLANTIS (OV 104) - OPF BAY 2 Atlantis is being bolted to the orbiter transporter today in preparation for the tow to the Vehicle Assembly Building at mid- night tonight. The gear is scheduled to be retracted later today. The orbiter's weight and center of gravity were determined yes- terday. Orbiter mate preparations are continuing in the Vehicle Assembly Building.
