            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.
