                     KSC SPACE SHUTTLE PROCESSING STATUS REPORT

          -----------------------------------------------------------------


                     STS-35  --  Columbia (OV 102)  -  Pad 39-B


               Mission managers are meeting today at Kennedy Space Center
          for the Flight Readiness Review for Space Shuttle mission STS-35
          and the ASTRO-1 observatory. Following the meeting, an
          announcement is expected targeting a specific date for the launch
          of Columbia.

               At pad B, countdown preparations continue today. The OMS/RCS
          hypergolic pressurization operations have been completed with the
          maneuvering systems now in the stabilization posture. The onboard
          cryogenic PRSD tanks were purged this morning. Following PRSD
          operations, work to close out the aft engine compartment began.
          The aft doors are scheduled to be installed in their flight
          configuration Wednesday.

               The payload bay doors on Columbia were opened this morning
          and access to the BBXRT payload is in work today. Final argon
          servicing of the X-ray telescope is slated to occur Thursday,
          followed by closeout of the payload bay and final door closure.



                     STS-39 -- Discovery (OV 103)  -  OPF Bay 1

               Ammonia boiler freon loop decay checks are continuing today
          and work to replace the cold plate manifold seals is underway.

               The nose landing gear doors have been lowered and brake and
          tire installations are proceeding.

               In the Hypergolic Maintenance Facility, a test of the
          screens in Discovery's OMS pods was conducted yesterday. A
          follow-on test will take place today.


                      STS-37 -- Atlantis (OV-104)  -  OPF Bay 2


               Post-flight safing operations continue on Atlantis in the
          Orbiter Processing Facility. Toxic vapor sniff checks continue
          today, followed by normal tile repair work. The payload
          strongbacks will be bolted into place today and the payload bay
          doors opened tonight.
