KSC SPACE SHUTTLE PROCESSING REPORT - THURSDAY, JUNE 22, 1989
STS-28 - COLUMBIA (OV 102) - OPF BAY 1
Yesterday, heat shields were installed on main engine number
one and the orbiter's radiators were inspected. Technicians are
replacing the liquid hydrogen recirculation pump package with a
new version designed to guard against shorting out. The first
launch attempt for the STS-30 mission was halted because of an
electrical short in one of the recirculation pumps.
The last few liners are being installed in the payload bay
today. Payload bay inspections and cleaning operations are
underway today. The payload bay doors are scheduled to be closed
this weekend. Technicians are continuing to bond tiles and
measure step and gap clearances between tiles.
Columbia's target date for tow to the Vehicle Assembly
Building is no earlier than June 30. While in the VAB, Columbia
will be mated with its external tank and solid rocket boosters.
STS-34 - ATLANTIS (OV 104) - OPF BAY 2
Three of four thrusters are being removed from the left
orbital maneuvering system pod to gain access to dynatube
fittings that need polishing. This work is being conducted while
the left pod is attached to the orbiter. Preparations for
checking out the liquid hydrogen main propulsion system are
underway. The right orbital maneuvering system pod, currently at
the Hypergolic Maintenance Facility undergoing post-flight
repairs, is scheduled to be installed this weekend.
STS-33 - DISCOVERY (OV 103) - OMRF
Power down work scheduled this week includes wiring and
instrumentation improvements and modification of the crew seats
to allow more room for the crew when they wear the partial
pressure suits. Discovery will be transferred to bay 1 when
Columbia is moved to the VAB.
STS-28 SOLID ROCKET BOOSTERS - VAB
Closeouts of the boosters and tank are underway in
preparation for mating with the orbiter Columbia.
STS-34 SOLID ROCKET BOOSTERS - VAB/RPSF
Workers are attaching the left forward center segment on the
booster stack in high bay 1. The left forward segment is
scheduled to be transferred to the VAB today. Meanwhile,
technicians are readying other STS-34 segments in the RPSF.
