KSC SHUTTLE STATUS - TUESDAY JULY 10, 1990 10 a.m.
STS-38 - ATLANTIS (OV 104) - LAUNCH PAD 39-A
Technicians are continuing to set up special instrumentation
for the liquid hydrogen tanking test now planned on Friday. This
test will be another attempt to isolate the source of the leak.
Today, special baggies are being installed around the 17 and 4
inch disconnects in an effort to contain leaks during the test.
The call-to-stations for the test is scheduled at 7 a.m.
Thursday and the Rotating Service Structure will be moved away
from the vehicle at 11 p.m. that night. Chilldown of the liquid
hydrogen lines is set for 7 a.m. Friday with slow fill occurring
shortly afterwards.
STS-35 - COLUMBIA (OV 102) - OPF BAY 2
Pneumatic leak checks of the newly installed 17-inch discon-
nect were successfully completed. Measurements of the disconnect
are planned tomorrow by the vendor.
Tests of the two 17-inch disconnects and seals used in the
STS-35 tanking test were conducted at the Rockwell plant in
Downey, Calif. Data analysis is continuing. Meanwhile, the 4-inch
recirculation line on the STS-35 tank will be replaced tomorrow.
After several tanking operations, the integrity of the exterior
thermal foam on the line was suspect. The concern is that some
of the foam could break away at liftoff and damage the orbiter's
tiles.
STS-41 - DISCOVERY (OV 103) - OPF BAY 1
The right hand radiator and auxiliary power unit number 3
were installed yesterday. Tests of the orbiter's systems are con-
tinuing today. Thermal protection system operations are underway
on all areas of the vehicle.
Tests are continuing on the two orbital maneuvering system
pods and forward reaction control system at the Hypergolic Main-
tenance Facility. Discovery is being prepared for the STS-
41/Ulysses flight, scheduled for launch in October.
STS-41 SOLID ROCKET BOOSTERS - VAB
Stacking of the right forward segment is underway today.
Closeout operations of the boosters are scheduled.
