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.
