KSC SHUTTLE STATUS - TUESDAY JULY 3, 1990 10 a.m.
STS-38 - ATLANTIS (OV 104) - LAUNCH PAD 39-A
Yesterday, a pressurization test of the external tank
revealed no leaks at the 17-inch disconnect area. The tank was
pressurized to flight level with helium while engineers monitored
for leakage at the 17-inch disconnect. As part of the test, the
tank pressure was decreased incrementally to collect baseline
leakage conditions at ambient temperatures.
Today, engineers will review data and get signatures from
the two leak detectors and sensors located on various parts of
Atlantis. The configuration of the vehicle will be maintained un-
til further direction from the team investigating the leak.
STS-35 - COLUMBIA (OV 102) - OPF BAY 2
Preparations are continuing to install the disconnect from
the Shuttle Endeavour on Columbia this week. Astro's Broad Band
X-ray Telescope was serviced with argon yesterday.
STS-41 - DISCOVERY (OV 103) - OPF BAY 1
Main engines 1 and 3 were installed yesterday. The number 2
main engine is scheduled to be installed today. Repairs to
Discovery's right payload bay door are continuing. Orbiter struc-
tural inspections and routine testing of all the orbiter's sys-
tems were among the activities worked this week. Thermal protec-
tion system operations are underway on all areas of the vehicle.
Tests are continuing on the two orbital maneuvering system
pods at the Hypergolic Maintenance Facility. Discovery is being
prepared for the STS-41/Ulysses flight, scheduled for launch in
October.
STS-41 SOLID ROCKET BOOSTERS - VAB
The right forward center segment is scheduled to be trans-
ferred to the Vehicle Assembly Building next week for mate to the
stack in the next few days. Closeout operations of the boosters
are scheduled.
