KSC SHUTTLE STATUS REPORT - FRIDAY, JAN. 4, 1991 10 a.m.
STS-39 - DISCOVERY (OV 103) - OPF BAY 1
The forward reaction control system (FRCS) was installed
overnight. An interface test of the FRCS is planned tomorrow.
Today, the payload bay doors are opened and the Ku-band antenna
is deployed for checks.
Engineers are evaluating a problem with the pilot's attitude
director indicator (ADI), a navigation aid that gives the crew
information about the orbiter's attitude in terms of pitch, yaw
and roll. Exhaust ducts of the three auxiliary power units were
tested and the data are being evaluated.
This weekend, the crossfeed lines between the orbital
maneuvering system pods are scheduled to be connected.
Discovery is being prepared for rollover to the Vehicle As-
sembly Building the end of this month.
STS-37 - ATLANTIS (OV 104) - OPF BAY 2
Atlantis is powered up today for routine tests. The new
general purpose computers are being installed in the orbiter.
Connections of the number 3 auxiliary power unit are continuing.
The remote manipulator system is at the OPF and remains scheduled
for installation this weekend. Instrumentation is being installed
for the flutter buffet modification. Atlantis is being readied
for launch scheduled in April.
STS-35 - COLUMBIA (OV 102) - VAB
Technicians removed the sleep stations from Columbia's crew
cabin yesterday. Tiles are being waterproofed and post-flight in-
spections in the aft compartment are beginning. Columbia will
remain in the Vehicle Assembly Building until Discovery is ready
to be transferred out of the OPF later this month.
STS-37 SOLID ROCKET BOOSTERS - VAB
Booster stacking operations are continuing. The left aft
center segment is being mated to the left booster today. The
left forward center segment is scheduled to be mated early next
week.
Technicians are aligning the new 17-inch liquid hydrogen
disconnect in the proper position on the external tank.
