KSC SPACE SHUTTLE PROCESSING REPORT - MONDAY, OCT. 17, 1988
STS-27 - ATLANTIS (0V 104) - OPF BAY 2
Preparations are underway to transfer the orbiter Atlantis
from the Orbiter Processing Facility to the Vehicle Assembly
Building.
Technicians are finishing up work on the orbiter's thermal
protection system. This morning only four cavities were reported.
Structural leak checks of the vehicle were started over the
weekend and are scheduled to be completed this week.
Last night, technicians removed the left outboard elevon
actuator and tonight are scheduled to install a new unit. The new
unit will be retested. After evaluating data from the actuator
following the frequency response test of the aerosurfaces,
engineers decided to pull this actuator. The data indicated there
were several spikes in the actuator pressure which were not fully
understood. The actuator will be shipped to the vendor for
analysis.
An assessment of the rollover date of Oct. 21 is underway.
The installation and retest of the new elevon actuator is being
factored into Atlantis's OPF schedule.
STS-29 - DISCOVERY (OV 103) - OPF BAY 1
Discovery's payload bay doors were closed over the weekend
while the frequency response test of the aerosurfaces was
conducted. Today, the doors will be reopened for preparations to
remove the OASIS payload.
Technicians are scheduled to remove the heat shields from
the orbiter's aft end. Once the shields are off, the three main
engines can be removed and taken to the engine service shop in
the VAB where several components will be replaced.
STS-28 - COLUMBIA (OV 102) - OMRF
Technicians are scheduled to install the power drive unit
for the body flap today. Orbiter power down modifications are
underway while Columbia is in the Orbiter Modification and
Refurbishment Facility.
STS-26 SOLID ROCKET BOOSTERS - HANGAR AF
The forward and aft segments have been shipped to Morton
Thiokol in Utah. Workers are loading the aft center segments on
flatbed trailers today. The segments will be taken to the rail
car area and loaded on the cars for shipment to Utah. The right
center segment is at Hangar AF and the left center segment is at
the rail car area.
