          KSC SHUTTLE STATUS REPORT - FRIDAY, MAY 10, 1991 - 10:30 AM

           STS-40/SPACELAB LIFE SCIENCES 1 - COLUMBIA (OV 102) - PAD 39-B
                                     LAUNCH - MAY

          WORK IN PROGRESS:
          - Post operations associated with loading hypergolic  propellants
          into  the  orbiter's orbital maneuvering system and reaction con-
          trol system storage tanks.
          - Preparations to install ordnance devices  on  the  vehicle  and
          check firing circuits.

          WORK SCHEDULED:
          -  Training  exercises  to  load  experiment  packages  into  the
          Spacelab late in the launch countdown.
          - Installation of ordnance devices this weekend.
          - Flight Readiness Review planned May 13-14.
          - Installation of the  two  spacesuits  for  contigency  purposes
          early next week.

          WORK COMPLETED:
          - Hypergolic propellant loading operations. Auxiliary power units
          and solid rocket booster hydraulic power units were serviced with
          hydrazine as part of this operation.

                     STS-43/TDRS - ATLANTIS (OV 104) - OPF BAY 2

          WORK IN PROGRESS:
          -  Preparations  to  replace  a  thruster  on  the  right orbital
          maneuvering system (OMS) pod.
          - Auxiliary power unit (APU) leak and functional tests.
          - Power reactant storage and distribution system testing.
          - Checks of the main propulsion system helium system.
          - Thermal protection system operations.
          - Preparations to remove the forward reaction control system  for
          replacement of two oxidizer thrusters.

          WORK SCHEDULED:
          - OMS thruster replacement this weekend.  The bay will be cleared
          for this job.
          - Removal of the forward reaction control system next week.
          - APU lube oil service next week.
          - Functional tests of the orbital maneuvering system pods.



                    STS-48/UARS - DISCOVERY (OV 103) - OPF BAY 1

          WORK IN PROGRESS:
          - Opening of the payload bay doors.
          - Post flight inspections.
          - Thermal protection system operations.

          WORK COMPLETED:
          - Offloaded residual propellant from the fuel cell storage tanks.
          - Installed access platforms in the aft compartment.
          - Main engine drying operations.
          - Removal of all tires.  They will be  sent  to  the  vendor  for
          evaluation.

          WORK SCHEDULED:
          - Main propulsion system tests next week.


                    STS- 49 - ENDEAVOUR (OV 105) - VAB High Bay 2

               Endeavour  was  transferred to the Vehicle Assembly Building
          high bay 2 this morning where work will be performed for the next
          few weeks. The orbiter will be jacked and leveled and access will
          be established.

               Next week,  the orbiter's weight and center of gravity  will
          be  determined.  Tail cone removal operations are planned the end
          of next week.
