yee@trident.arc.nasa.gov (Peter E. Yee) (08/21/90)

           KSC SHUTTLE STATUS REPORT - THURSDAY, AUGUST 16 1990  8:30 A.M.

                        STS-35 - COLUMBIA (OV 102) - PAD 39-A

               The helium signature leak test of the shuttle's  three  main
          engines  and  main  propulsion system is set to begin at about 10
          a.m.  today.  This test is designed to identify any leaks  within
          the system  using gaseous helium.  Retest of orbiter main propul-
          sion system flow control valves delayed the  test  a  few  hours.
          Yesterday,  the  Orbiter  Midbody Umbilical Unit was connected to
          the shuttle.

               Preparations  for  servicing  the  orbiter  with  hypergolic
          propellants are continuing.  Servicing is set to begin Friday af-
          ternoon and will continue through the weekend.  The pad  will  be
          closed  for  this  operation.  Monomethylhydrazine  and  nitrogen
          tetroxide will be loaded into the orbiter's onboard storage tanks
          for the orbital maneuvering system pods and the reaction  control
          system.

               Today,  KSC managers will meet for the routine Launch Readi-
          ness Review to go over the status for launching Columbia and  the
          Astro payload on Mission STS-35.

               The Flight Readiness Review,  where shuttle managers set the
          official launch date, is scheduled for Aug. 20-21 here at Kennedy
          Space Center.

                       STS-38 - ATLANTIS (OV 104) - OPF BAY 2

               Access to the vehicle is being established. The orbiter will
          spend about four weeks in the OPF being readied  for  the  STS-38
          mission.  Meanwhile, technicians are removing the 17-inch discon-
          nect  assembly and feedline from the external tank.  The feedline
          and assembly will be shipped  to  Marshall  Space  Flight  Center
          this weekend.


                       STS-41 - DISCOVERY (OV 103) - OPF BAY 1

               Rigging  of  the main landing gear doors and tile operations
          around the doors are underway. All areas of the vehicle are being
          closed out for roll to the VAB next week.  Work  to  install  the
          galley is underway.  The date for rolling the vehicle over to the
          VAB is being evaluated.  The routine rollover review meeting will
          be held Friday.
