KSC SPACE SHUTTLE PROCESSING REPORT FOR - Monday, July 18, 1988
STS-26 - DISCOVERY (OV 103) - PAD 39-B
Engineers have stablilized the leak in the Orbital
Maneuvering System pod by pressurizing the reaction control
system oxidizer storage tank with helium. Today the leak rate is
being monitored while other work to prepare the vehicle for the
"wet" tanking test and the Flight Readiness Firing are underway.
Engineers determined that the small leak in a dynatube
fitting in the fill line to the RCS oxidizer tank will not affect
the tests scheduled for next week. Engineers will be analyzing
the data from the cobra borescope videos and the leak rates over
the next few days to determine the best possible way to proceed
after the FRF. No definite schedule plans are expected until
after the FRF.
The countdown for the "wet" tanking test is scheduled to
begin Friday 11:30 p.m. with the T-0 is scheduled for 7 a.m. A
few hours later the 72-hour scrub turnaround activities will be
exercised prior to the 22-second main engine test firing.
STS-27 - ATLANTIS (0V 104) - OPF BAY 2
The leak and functional tests of the auxiliary power units
were conducted over the weekend with only minor problems
reported. Systems testing of the power reactant storage and
distribution system is scheduled to continue through the week.
Two of the close circuit television system cameras have been
installed. Technicians are scheduled to test the orbiter's Ku-
band antenna today and stow it later this week. Also this week
technicians are preparing to install the forward reaction control
system currently targeted for this weekend.
STS-28 - COLUMBIA (OV 102) - OPF
Orbiter modifications scheduled this week include crew
escape, 17-inch external tank disconnect, and the RTV heat sink
modification. Thermal protection system operations are continuing
as scheduled. Power up operations are planned to start next
month.
STS-27 SOLID ROCKET BOOSTERS - RPSF
Booster "build up" operations are continuing on the left and
right aft segments for the STS-27 launch. The external tank
attach rings have been installed on both segments and workers are
installing cables and instrumentation.
