STS-26 - DISCOVERY (OV 103) - OPF BAY 1
Activities are underway to ready the Space Shuttle Discovery
for the upcoming STS-26 mission. Orbiter closeouts are active on
all areas of the orbiter. The payload bay doors are closed while
thermal protection system technicians examine the hinges and
their protective covers.
A functional test of the payload bay doors is planned for
today. Preparations for leak checks of the hydraulic system and
the landing gear functional test are scheduled today. Discovery
is scheduled to be rolled to the VAB the end of next week.
STS-27 - ATLANTIS (0V 104) - OPF BAY 2
Technicians are scheduled to deploy the radiators today and
will continue with orbiter modifications including crew escape,
chin panel, elevon cove seal improvements and installing
instrumentation for the RTV heat sink modification.
STS-28 - COLUMBIA (OV 102) - OMRF
Power down modifications scheduled today include crew escape
and installation of RTV heat sink strips. Technicians will
inspect an auxiliary power unit gaseous nitrogen fuel tank line
and repair a cold plate.
STS-26 SOLID ROCKET BOOSTERS - VAB
Closeout operations are underway on the STS-26 solid rocket
booster field joints. During closeout activities, technicians
bond instrumentation, heaters, sensors, install a moisture seal
and bond cork to the outside of the joint. After the joints are
closed out, the external tank will be attached to the SRBs.
Monday preparations are scheduled to begin for mating the
external tank and the mate is scheduled for next Wednesday.

Monday, June 6, 1988
An integrated launch simulation is scheduled tomorrow with a
call-to-stations at 6 a.m. All lead launch team members for STS-
26 are required to participate in this test. The simulated T-0 is
scheduled for 9:50 a.m. and there is a one-hour window.
STS-26 - DISCOVERY (OV 103) - OPF BAY 1
Functional tests of the main landing gear and the payload
bay doors were successfully conducted over the weekend. Many of
the main propulsion system closeouts were accomplished
over the weekend.
A sharp edge inspection of the orbiter's payload bay is
planned this week. Astronauts will inspect the orbiter for any
sharp edges that may snag a space suit if an unplanned space walk
became necessary during the STS-26 mission.
Thermal protection system operations are active on all areas
of the orbiter. Technicians are repairing tiles and installing
gap fillers and taking measurements of the tiles. Rollover of the
orbiter to the VAB is scheduled for no earlier than late next
week.
STS-27 - ATLANTIS (OV 104) - OPF BAY 2
Power down operations are scheduled until Wednesday while
the Firing Rooms are being used for power on testing of Discovery
and for tomorrow's Integrated Launch Simulation.
Thermal control blankets inside the orbiter are being
measured to make sure they are the proper thickness. Technicians
are performing inspections of the right hand radiator. This week
leak checks of gaseous nitrogen lines and water lines in the
shuttle's environmental control system are scheduled.
STS-28 - COLUMBIA (OV 102) - OMRF
Installation and inspections of cold plates are planned this
week. Modifications scheduled this week include crew escape and
RTV heat sink. Routine structural inspections are also planned.
STS-26 SOLID ROCKET BOOSTERS - VAB
Closeouts of the STS-26 solid rocket boosters continued
through the weekend and are active today. Preparations for mating
the external tank to the SRBs began today with the actual mating
of the tank planned for early Wednesday morning.
Three of the solid rocket motor segments for STS-27 arrived
by rail car yesterday and offload operations are scheduled today
at the Rotation Processing and Surge Facility. Stacking is
scheduled to begin the end of next month.
