KSC SPACE SHUTTLE PROCESSING REPORT - TUESDAY, JUNE 27, 1989
STS-28 - COLUMBIA (OV 102) - OPF BAY 1
Shuttle managers met yesterday and today in a routine pre-
launch meeting to discuss the readiness of the orbiter Columbia
for its move to the Vehicle Assembly Building. After considering
the amount of work left on Columbia, the target date for
transferring Columbia to the VAB was moved to no earlier than
Saturday, July 1, at 12 noon. Management will meet again on
Friday to discuss the remaining work, including tile, and the
status of the investigation of the main engine test firing
incident at Stennis Space Center, Mississippi last Friday. All
shuttle program elements were commended for the significant
amount of work completed on Columbia to date.
Tonight, technicians are scheduled to replace two electronic
boxes in Columbia. One of the boxes, called a motor control
assembly (MCA), sends commands to the orbiter's vent doors,
external tank doors and orbital maneuvering system crossfeed
valves. In addition, the MCA relays information about the
position of those systems to the orbiter's cockpit. The MCA
experienced internal blown fuse link. An electronic box, located
in middeck, for the pilot's heads up display (HUD) will be removed
tonight because of an intermittent lighting problem. Retest of both
components is scheduled.
A positive pressure structural leak test of the aft
compartment is planned tonight. Preparations are continuing for a
frequency response test of the orbiter's aerosurfaces this week.
Technicians are continuing to bond tiles, install gap
fillers and fit and install thermal blankets on the payload bay
doors. Technicians finished painting the name Columbia on the
left and right forward fuselage today and will finish painting
the flag tonight.
STS-34 - ATLANTIS (OV 104) - OPF BAY 2
Preparations are underway to install tires on the main
landing gear this week. Testing of the right orbital maneuvering
system pod is scheduled to begin tonight. Coolant lines were
recently installed for the radioisotope thermoelectric generators
(RTGs), used to power the Galileo spacecraft, and leak checks are
planned this week. Orbiter systems will be tested this week.
STS-33 - DISCOVERY (OV 103) - OMRF
Power down work and modifications continue this week in the
forward, mid and aft sections of the orbiter. Discovery will be
transferred to bay 1 shortly after 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
Technicians are preparing the right aft booster for stacking
on the mobile launcher platform. Meanwhile, the last three right
hand segments are being readied for stacking in the RPSF.kean@mist.CS.ORST.EDU (Kean Stump) (06/28/89)

Re: The Incident I just noticed this yesterday. There was a `short' in the newspaper about it. Apparently there was a fire in one of the engines during testing. The paper said that the launch of Columbia may very well be moved back to late summer because of it. There wasn't much info content in the article (it was only two paragraphs long!) so I hope someone with more official knowledge will fill in the gaps. David B.

What actually happened was that a turbopump "flew apart" during a static firing test of an SSME (an engine removed from Discovery, I think). Nothing happened to Columbia at all. But until they figure out why the pump self-destructed, they can't rule out a similar threat to Columbia. Hence the potential for a schedule hit -- they won't fly with this question unanswered. -- "My God, Thiokol, when do you \\ Tom Neff want me to launch -- next April?" \\ uunet!bfmny0!tneff
