KSC SPACE SHUTTLE PROCESSING REPORT FOR - Tuesday, July 19, 1988
STS-26 - DISCOVERY (OV 103) - PAD-39 B
Engineers are continuing to monitor the leak rate in the
left hand orbital maneuvering system pod at pad 39-B. The leak is
stable and is not causing complications inside the pod.
Preparations for the "Wet" tanking test and Flight Readiness
Firing are underway. This week, technicians are busy closing out
the aft compartment and performing the last few tests prior to
next week's tests. Today a leak check of the external tank
liquid hydrogen fill and drain quick disconnects are planned.
Later today the power reactant storage and distribution
system is scheduled to be purged in preparation for next week's
tests. During the tests the PRSD tanks will be loaded with liquid
hydrogen and liquid oxygen.
The countdown for the Wet Countdown Demonstration Test
(WCDDT) is targeted to begin at 11:30 p.m. Friday, July 22 with
the T-0 planned for 7 a.m. Monday, July 25. The T-0 for the
Flight Readiness Firing is targeted for 7:30 a.m. Thursday, July
28.
STS-27 - ATLANTIS (0V 104) - OPF BAY 2
Preparations for checking out the orbiter's water spray
boilers are underway. Systems testing of the power reactant
storage and distribution system is underway. Instrumentation is
being calibrated for the chin panel. Operations to prepare the
forward reaction control system cavity for the installation later
this week are active. Thermal blankets are being installed along
with other thermal protection system operations. Orbiter
modifications are continuing.
STS-28 - COLUMBIA (OV 102) - OMRF
The strongbacks have been attached to the payload bay doors
in preparation for door opening later this week. This will allow
access for workers to implement modifications to systems and
components located inside the bay. Thermal protection system
operations are continuing. The smaller white diced tile
originally on Columbia are being replaced with larger thermal
blankets like those on the other two orbiters.
STS-27 SOLID ROCKET BOOSTERS - RPSF
"Build up" operations are continuing on the left and right
aft solid rocket boosters. A leak check of the right aft nozzle
is scheduled today and preparations to install instrumentation
and cables on the left aft booster are underway. Stacking is
scheduled to begin with the left aft booster the end of this
month in the Vehicle Assembly Building.
