KSC SHUTTLE STATUS REPORT - MONDAY, SEPT. 25, 1990 11:30 AM
STS-41 - DISCOVERY (OV 103) - PAD 39-B
The two space suits carried aboard Discovery for contingency
purposes will be installed in the airlock tomorrow. Also tomor-
row, the Inertial Upper Stage for the Ulysses spacecraft will be
tested to simulate events of launch day.
On Friday, hypergolic propellant tanks on board the orbiter
will be pressurized and closed out, and ordnance devices will be
installed and firing circuits will be checked.
Closeouts of the orbiter's aft compartment are underway.
This work includes applying foam to various areas of the main
propulsion system, final inspections of various components, main
engine closeouts, cleaning and removing platforms for flight.
Discovery and the Ulysses spacecraft are being prepared for
an October 6 launch date. The launch countdown will begin at 3:30
a.m. EDT Wednesday, Oct. 3, at the T-43 hour mark, leading up to
the liftoff at 7:35 a.m. EDT.
STS-35 - COLUMBIA (OV 102) - PAD 39-A
Leak tests are being conducted on the main propulsion system
valves, actuators and areas of the recirculation pump package to
try to isolate the source of the leak. The KSC team is working
with the tiger team assigned to find the fuel leak.
Details and requirements are being identified for a tanking
test next month. A definite date for the test has not yet been
set.
Technicians removed an auxiliary power unit yesterday. This
unit will be installed on Atlantis this week for the STS-38 mis-
sion.
STS-38 - ATLANTIS (OV 104) - OPF BAY 2
Freon cooling loop 2 has been serviced as part of the opera-
tions to replace the flash evaporator. Tests are planned on the
flash evaporator this week. Preparations to install an auxiliary
power unit in the number 3 position are underway today. Atlantis
is being prepared for rollover to the VAB early next month.
