KSC SPACE SHUTTLE PROCESSING REPORT - MONDAY, APRIL 17, 1989 STS-30 - ATLANTIS (0V 104) - PAD 39-B This past weekend, workers completed part one of vehicle ordnance operations and pressurized Atlantis' onboard hypergolic propellant storage tanks for flight. Today, the helium signature test of the main propulsion system is scheduled to begin and will continue through tomorrow. This test will indicate if there are any leaks in the system. The space suits are scheduled to be installed in the airlock tomorrow in parallel with the leak test. There is no space walk planned for this mission, however, the suits are always flown in case one should become necessary. The Frequency Response Test (FRT), which cycles the main engine valves, was completed last week and heat shields have been installed around the main engines. Launch of mission STS-30 is scheduled for April 28 at 2:24 p.m. EDT with a window of 23 minutes. The countdown is scheduled to begin Tuesday, April 25 and the flight crew will arrive that afternoon. STS-28 - COLUMBIA (OV 102) - OPF BAY 1 Orbiter systems testing is continuing this week including checkout of the Ku-band antenna, main propulsion system testing, water spray boilers, air revitalization system, waste containment system and power reactant storage and distribution system. The orbiter's radiators have been installed. Thermal protection system operations are continuing. Work is underway to prepare the two orbital maneuvering system pods for installation on the orbiter. STS-33 DISCOVERY (OV 103) - OPF BAY 2 Structural post-flight inspections and window polishing are continuing this week. A systems test of the power reactant storage and distribution system is underway. Other activities planned include draining the auxiliary power units' catch bottles, tile waterproofing and inspection of heat shields. STS-28 SOLID ROCKET BOOSTERS - VAB/RPSF The right aft booster on Friday was stacked on the launch platform and technicians are calibrating instrumentation. The left forward segment is scheduled to be transferred to the VAB this week for stacking. Joint closeouts are active on the left booster. At the RPSF, technicians are preparing other STS-30 segments for stacking in the RPSF.
