KSC SPACE SHUTTLE PROCESSING REPORT FOR - Tuesday, July 12, 1988
STS-26 - DISCOVERY (OV 103) - VAB
Loading of the oxidizer, nitrogen tetroxide, into
Discovery's Orbital Manuevering System pods and reaction control
system was completed yesterday. Today workers are scheduled to
load the fuel, monomethyl hydrazine, into Discovery's tanks. Two
of the three auxiliary power units have been serviced with
hydrazine and the third will be serviced today. The job is
estimated to be completed by this evening.
Later this week, workers will be performing a fit check of
the crew escape pole in Discovery's crew module. Also
preparations for the Flight Readiness Firing will commence when
the pad reopens for normal work. The 20-second test firing of
Discovery's main engines is scheduled for Monday, July 25 at 7:30
a.m. The FRF will be preceded by the "wet" tanking test scheduled
for July 22 at 7 a.m. For both tests the external tank will be
filled with its flight load of a half a million gallons of liquid
hydrogen and liquid oxygen. After each test the external tank
will be drained.
STS-27 - ATLANTIS (0V 104) - OPF BAY 2
The last two helium tanks for the main propulsion system
were installed yesterday. A systems test of the power reactant
storage and distribution system is going well this week.
Installation of the chin panel for flight is scheduled for today.
A leak and functional test of the auxiliary power units is
planned for this weekend. Thermal protection system operations
are ongoing along with orbiter modifications.
STS-28 - COLUMBIA (OV 102) - OMRF
Access platforms have been positioned around the shuttle and
orbiter modifications scheduled today include crew escape,
thermal protection system operations and RTV heat sink.
STS-26 SOLID ROCKET BOOSTERS - RPSF
The right aft booster was mated to its aft skirt yesterday
and an inspection of the case is underway today. Also in the
RPSF, "build up" operations are continuing on the left aft
booster. The external tank attach ring has been installed and
foaming is scheduled today. Mobile Launcher Platform 1 will be
moved into VAB high bay 3 in preparation for the stacking
operation scheduled to begin the end of this month.
