KSC SHUTTLE STATUS REPORT - THURSDAY, AUGUST 16 1990 8:30 A.M. STS-35 - COLUMBIA (OV 102) - PAD 39-A The helium signature leak test of the shuttle's three main engines and main propulsion system is set to begin at about 10 a.m. today. This test is designed to identify any leaks within the system using gaseous helium. Retest of orbiter main propul- sion system flow control valves delayed the test a few hours. Yesterday, the Orbiter Midbody Umbilical Unit was connected to the shuttle. Preparations for servicing the orbiter with hypergolic propellants are continuing. Servicing is set to begin Friday af- ternoon and will continue through the weekend. The pad will be closed for this operation. Monomethylhydrazine and nitrogen tetroxide will be loaded into the orbiter's onboard storage tanks for the orbital maneuvering system pods and the reaction control system. Today, KSC managers will meet for the routine Launch Readi- ness Review to go over the status for launching Columbia and the Astro payload on Mission STS-35. The Flight Readiness Review, where shuttle managers set the official launch date, is scheduled for Aug. 20-21 here at Kennedy Space Center. STS-38 - ATLANTIS (OV 104) - OPF BAY 2 Access to the vehicle is being established. The orbiter will spend about four weeks in the OPF being readied for the STS-38 mission. Meanwhile, technicians are removing the 17-inch discon- nect assembly and feedline from the external tank. The feedline and assembly will be shipped to Marshall Space Flight Center this weekend. STS-41 - DISCOVERY (OV 103) - OPF BAY 1 Rigging of the main landing gear doors and tile operations around the doors are underway. All areas of the vehicle are being closed out for roll to the VAB next week. Work to install the galley is underway. The date for rolling the vehicle over to the VAB is being evaluated. The routine rollover review meeting will be held Friday.
