          - astronaut arrival at 3:30 p.m. Sunday
          - close payload bay doors at 8:45 p.m. Sunday


          Vehicle: OV-102/Orbiter Columbia
          Current location: OPF Bay 2
          Mission: STS-55/Spacelab-D2         Inclination: 28.45 degrees
          Launch timeframe: February, wk 4    Nominal Landing Site: KSC
          Mission Duration: 8 days 22 hours   Crew size: 7

          STS-55 IN WORK:

          - troubleshooting payload bay door latching
          - installation of main engine heat shields
          - functional testing of  waste containment system
          - testing of OMS/RCS redundant electrical system


          STS-55 WORK SCHEDULED:

          - payload bay door cycle and latch tests on Sunday
          - install Spacelab D-2 laboratory module on Monday
          - mating external tank to solid rocket boosters on Jan. 13


          STS-55 WORK COMPLETED:

          - fuel cell checkout
          - freon coolant loop checkout
          - main engine installation
          - Spacelab tunnel installation


          ISSUES AND CONCERNS:

          Engineers are troubleshooting difficulty latching the payload bay
          doors.  As a result Spacelab D-2 installation has been
          rescheduled from today until Monday.  The initial troubleshooting
          will focus on the strongbacks attached to the doors.  It is not
          clear at this time whether there might be direct schedule impact.
          In the VAB, the left forward booster segment which was destacked
          immediately before the Christmas holidays has been restacked and
          leak checks have been successful.
