KSC SHUTTLE STATUS - WEDNESDAY JULY 18, 1990 11 a.m.
STS-38 - ATLANTIS (OV 104) - LAUNCH PAD 39-A
Today, helium will be injected into the baggies around the
flange and 17-inch disconnect area in an effort to gain a better
understanding about the leakage that occurred during the tanking
test last Friday. Later today, the baggies and sense lines will
be removed and dye will be injected into the foam around the
flange. The foam will be cut to determine if the dye reveals any
leak paths through the foam. Managers want to determine if any
leakage between baggies occurred during the test.
The bags will be reinstalled and the tank will be pres-
surized early tomorrow morning to check for leaks in the baggies.
Workers at KSC are preparing for another tanking test next Wed-
nesday, July 25.
Preparations to remove auxiliary power unit number 3 are
continuing today. The unit is scheduled to be removed Thursday
and Friday.
STS-35 - COLUMBIA (OV 102) - OPF BAY 2
Operations to install the 17-inch disconnect into Columbia
are continuing today. Parker Hannifan representatives are
scheduled to arrive at KSC this week to perform tests of the new
disconnect. Calibrations of the inertial measurement units were
completed yesterday.
STS-41 - DISCOVERY (OV 103) - OPF BAY 1
Rigging of the main landing gear doors is underway. Work is
beginning to install RTG water lines and wiring in the aft com-
partment. Thermal protection system operations are underway on
all areas of the vehicle. Pre-flight tests are continuing on the
other systems.
The left orbital maneuvering system pod is being rotated and
installed in the transporter for transfer to the OPF on second
shift tonight. Leak tests and thruster replacements are continu-
ing on the right orbital maneuvering system pod and forward reac-
tion control system (FRCS) at the Hypergolic Maintenance
Facility. The FRCS is scheduled to be delivered to the OPF Satur-
day for installation on Monday. Discovery is being prepared for
the STS-41/Ulysses flight, scheduled for launch in October.
