KSC SPACE SHUTTLE PROCESSING REPORT - WEDNESDAY, APRIL 5, 1989
STS-30 - ATLANTIS (0V 104) - PAD 39-B
The interface verification test of the Magellan payload was
successfully completed ahead of schedule earlier today. The test
verifies connections between the orbiter and the payload. The
end-to-end test of the Magellan and Interial Upper Stage and
ground stations is planned for Saturday.
Yesterday, technicians replaced a seal on the last high
pressure oxidizer turbo pump after a detailed inspection that was
prompted by an unusual noise heard during the installation. The
pump is now being bolted back into place allowing technicians to
begin making over 30 connections necessary to complete the
installation later this week.
The Countdown Demonstration Test is scheduled to begin
Thursday, April 6 and will culminate with a simulated engine
cutoff at 11 a.m. Friday. The test serves as a dress rehearsal
for the flight crew and launch team.
STS-28 - COLUMBIA (OV 102) - OPF BAY 1
Orbiter systems testing is underway today including checkout
of the forward reaction control system. Orbiter systems are being
checked out as return-to-flight activities continue. Leak and
functional testing of the auxiliary power units is scheduled this
week. Thermal protection system operations are continuing.
STS-33 DISCOVERY (OV 103) - OPF BAY 2
Technicians have removed two of the main engines and the
last engine is being removed today. One of the engines will be
sent back to Rocketdyne in Canoga Park, Calif. for repairs to a
crack in its main comubustion chamber. Removal of the SHARE heat
pipe is also scheduled to begin today. A systems test of the
power reactant storage and distribution system is planned this
week.
STS-28 SOLID ROCKET BOOSTERS - VAB/RPSF
The left aft booster was transferred from the RPSF to the
VAB Monday and stacked on the mobile launcher platform.
Technicians are hooking up electrical umbilicals to the booster
today. The left aft center segment is scheduled to be transferred
to the VAB transfer aisle today in preparation for stacking.
Meanwhile, other segments are being prepared for stacking in the
RPSF.
