                     KSC Space Shuttle Processing Status Report

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

                  STS-38  --  Atlantis (OV 104)  -  Launch Pad 39-A

               A liquid hydrogen special tanking test was conducted this
          morning on Atlantis at pad 39-A. Chill down of the liquid
          hydrogen lines began at 7:30 followed by slow and fast fills.
          During the fast fill portion of the test, a liquid hydrogen leak
          was detected in the area of the flange joint on the external tank
          side of the 17-inch umbilical lines. This leak then reappeared
          during subsequent slow fill operations. The leak appears to be
          similar to the one previously detected during earlier tests.
          Engineers will be digesting the data gathered during today's test
          and presenting the information to program management.

               Following the test this morning, engineers prepared to
          perform an Auxiliary Power Unit hot fire test on APU number 3.


                     STS-35  --  Columbia (OV 102)  -  OPF Bay 2

               Work continues on installation of the 17-inch liquid
          hydrogen disconnect. Tightening of the B-nuts on the disconnect
          and aft compartment closeouts are in work today. The BBXRT
          payload has been serviced.


                     STS-41 -- Discovery (OV 103)  -  OPF Bay 1

               Discovery's forward reaction control system was moved to the
          Orbiter Processing Facility's transfer aisle last night and
          operations are underway for its installation on the orbiter. The
          left OMS pod was electrically disconnected yesterday to allow
          workers access to repair a slightly misaligned thermal barrier.
          Also, work on the right hand main landing gear is continuing.

               Discovery's next mission is Ulysses. Launch of STS-41 is
          scheduled for October 5, 1990, from pad 39-B.
