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.
