                 PAYLOAD  STATUS REPORT: MISSIONS STS-32 AND STS-35
                         Prepared at 1:30 P.M. Nov. 7, l989
 
          STS-32  --  SYNCOM IV-05, LDEF Retrieval
 
               Kennedy Space Center workers are preparing  to  receive  the
          SYNCOM-IV  satellite  for  final  stages of processing next week.
          SYNCOM is scheduled to be transferred from  Astrotech  in  Titus-
          ville,  FL.  to  the Vertical Processing Facility (VPF) overnight
          Monday, Nov. 13. The satellite has been at the Astrotech facility
          since Sept. 6 undergoing early stages of flight preparation.
 
               Pre-arrival platform and alignment operations have been com-
          pleted at KSC,  along with clean room preparations.    Communica-
          tions systems are ready to support processing and the CITE (Cargo
          Integration  and Test Equipment) test Nov.  15.  Technicians have
          successfully corrected problems with two land lines.  Flight  and
          ground software systems have been checked and validated.
 
               The  satellite  is expected to spend about 6 days in the VPF
          before going to the pad. During that time, a launch readiness
          test and a sharp-edge inspection will be  held  as  well  as  the
          CITE.
 
          STS-35 -- ASTRO-1, BBXRT
 
               Astro-1  is a payload consisting of four optical instruments
          capable of performing independent or simultaneous observations of
          selected targets.  They are: 1) three ultraviolet (UV) telescopes
          aligned to each other on an Instrument Pointing System (IPS)  and
          mounted  to  two  Spacelab  pallets;  and  2)  an X-ray telescope
          mounted on a Two-Axis Pointing System (TAPS) secured by a special
          support structure.  The Astro-1 payload is currently scheduled to
          fly  aboard Columbia in April,  l990.  A night launch is planned.
          The Astro payload is the first of a series of Astro missions that
          will make precise astronomical measurements.
 
               Processing work, including component testing, is well under-
          way at KSC for all instruments. Upcoming work includes argon ser-
          vicing for BBXRT and testing of the IPS, as well as electrical
          wiring work.  The processing teams have successfully  resolved  a
          gyro problem on BBXRT,  and are assessing the condition of a tape
          recorder  on  the  Spacelab  pallet.   Hardware  inspections  and
          software  tests/evaluations  are  also  on  the near-term support
          schedule.
