KSC SPACE SHUTTLE PROCESSING REPORT FOR - Wed. Sept. 14, 1988
STS-26 - DISCOVERY (OV 103) - PAD 39-B
Yesterday technicians installed the three gaseous oxygen
(GOX) flow control valve poppets. Retest of the GOX system is
going well. Engineers are continuing to troubleshoot a very small
leak in the liquid hydrogen system. It has not been found yet and
workers are trying to isolate it today.
Preparations are underway for the helium signature leak test
of the main propulsion system and three main engines. The test is
scheduled to begin tomorrow morning.
Thermal protection system repairs and orbiter aft closeouts
are underway.
Meanwhile, Shuttle program managers are continuing the
Flight Readiness Review today to assess the program's readiness
for the STS-26 launch scheduled for later this month.
STS-27 - ATLANTIS (0V 104) - OPF BAY 2
Technicians are installing heat shields and making
preparations to install the third main engine on Friday.
Interface verification testing of the connections between the
orbital maneuvering system pods and the orbiter are scheduled
today. A functional test of the waste containment system is
continuing today. Operations to install the gaseous oxygen
manifold and checks of the main propulsion system are underway
this week.
Next month, Atlantis is scheduled to be moved to the VAB for
mating with the boosters and external tank and then rolled out to
Launch Pad 39-B for launch in November.
STS-28 - COLUMBIA (OV 102) - OPF BAY 1
Columbia is scheduled for power up testing the end of next
week. Preparations are underway to support powering up the
orbiter after a modification period. As Columbia's systems are
installed, they will be retested and verified. Orbiter return-to-
flight inspections and system improvements are continuing.
STS-27 SOLID ROCKET BOOSTERS - VAB
Joint closeouts are active on all the remaining field joints
of the STS-27 solid rocket motors. The external tank is scheduled
to be mated to the boosters next week.
