Turnaround processing of Discovery continues to progress on schedule. On Atlantis, workers changed a flash evaporator water valve yesterday and will re-service and test the valve tomorrow. The high pressure fuel ducts on Atlantis' main engines are being tested today with penetrating dye. Work on Columbia includes freon loop sampling and topping off, and regulator flow checks in the forward reaction control system The aft reaction control system will be inspected early next week. Inside Columbia's payload bay, the Astro-1 Broad Band X-ray Telescope is being serviced today with argon. KSC showed to reporters the first of Endeavor's main engines to arrive at the center. About a dozen reporters photographed the engine, #2032, and interviewed the Rocketdyne KSC launch site director, John Plowden. * * * * * * * * * * * * * * * * * * * * * * * * * * The Galileo spacecraft is now 19.4 million miles from Earth, and more than 107 million miles from the Sun.

It would be difficult for the US government to prohibit US satellites from being transported to Cape Canaveral, especially if the Soviet rockets were launched by US personnel. -- David Anderman Internet: David.Anderman@ofa123.fidonet.org Compuserve: >internet:David.Anderman@ofa123.fidonet.org -------------------------------------------------------------------------- ------------------------------ Return-path: X-Andrew-Authenticated-as: 0;andrew.cmu.edu;Network-Mail Date: 3 Nov 90 01:14:43 GMT From: trident.arc.nasa.gov!yee@ames.arc.nasa.gov (Peter E.

Subject: Voyager Update - 11/02/90 Sender: space-request@andrew.cmu.edu To: space@andrew.cmu.edu Voyager Status Report November 2, 1990 Voyager 1 The Voyager 1 spacecraft collected routine UVS (Ultraviolet Spectrometer) data on sources HD1679 and ANTI VGR 2. The ANTI VGR 2 is a slew to a position pointing away from Voyager 2 to observe background levels of interstellar hydrogen in the sky, and was performed on October 24. On October 19, a TLC (Tracking Loop Capacitor test) was cancelled because the Pioneer 11 spacecraft emergency took two hours of the Spain 70 meter antenna time originally scheduled for Voyager 1. The TLC was re-scheduled and completed on October 22. On October 23, one frame of high-rate PWS (Plasma Wave) was recorded. On October 22, a patch was uplinked to the FDS (Flight Data Subsystem) to correct the PRA (Planetary Radio Astronomy Subsystem) POR (Power-On Reset) recovery procedure. This patch will be tested the next time the PRA has a POR. On October 24, science calibrations for PLS (Plasma), MAG (Magnetometer), and LECP (Low Energy Charged Particles) instruments was completed. Also, the TMU (Telemetry Modulation Unit) subcarrier was changed to high-rate. On October 25, the TMU went to low subcarrier for execution of a PABML (Pre-Backup Mission Load) mini-sequence, and a AACS (Attitude and Articulation Control Subsystem) memory readout was completed. Successful loading of the AACS was confirmed by AACS memory readout. Voyager 2 The Voyager 2 spacecraft collected routine UVS data on sources EG 165 and ANTI VGR 1. On October 25, the scan platform was slewed to point away from Voyager 1 to view background levels of interstellar hydrogen (ANTI VGR 1). There was a PWS High-rate record frame on October 23. Also on October 23, 3-way ranging was performed from the 70 meter antenna in Australia to the 34 meter antenna in Spain. On October 23, the MAG, LECP, and PLS instruments were calibrated. Only the start of this calibration was verified before loss of DSN (Deep Space Network) station coverage.

Subject: Galileo Update - 11/02/90 Sender: space-request@andrew.cmu.edu To: space@andrew.cmu.edu GALILEO STATUS REPORT November 2, 1990 As of noon (PST) Thursday, November 1, 1990, the Galileo spacecraft is 19,397,690 miles from the Earth and traveling at a heliocentric speed of 56,790 miles per hour; distance to the Sun is 106,946,870 miles (1.13 AU). Round trip light time is 3 minutes, 32 seconds. A SITURN to lead the sun was successfully performed on October 26. The turn, about 10.5 degrees, resulted in the spacecraft leading the sun by nearly 6 degrees. Spacecraft performance during the activity was normal and without incident. Cruise science Memory Readouts (MROs) were successfully performed for the MAG (Magnetometer) and DDS (Dust Detector) instruments on October 26 and November 1; a single MAG MRO was also performed on October 29. A NO-OP command was sent on October 29 to reset the Command Loss Timer to 216 hours, the planned value for this mission phase. Four additional delta DOR (Differential One-way Ranging) navigation activities were performed - two on October 29 and two on November 1. Both passes on October 29 were successful. Only one pass using was successful on November 1, the other pass was lost due to the Goldstone 70 meter station not receiving the proper predict information. A total of 17 of the planned 27 delta DOR activities are complete; 13 were successful. The 20th RPM (Retro Propulsion Module) flushing activity was successfully performed on November 1. All thrusters were flushed during this activity except for the P-thrusters which were used on October 26 for the sun point activity. Successful flushing was directly confirmed and observed since the engineering downlink data rate was at 1200 bps (bits/second). The PLS (Plasma) pyro-actuated sun shade was successfully retracted on November 1. All spacecraft pyro-related telemetry was as expected. Indication of shade retraction was quickly observed by the AACS (Attitude and Articulation Control Subsystem) acquisition sensor temperature telemetry. Later that day three of four PLS temperatures indicated a slight increase. Total confirmation of retraction will be available about 24-30 hours when all PLS temperatures are expected to reach steady state levels. The AC bus imbalance measurement remained stable near 48.7 volts. The DC measurement exhibited a 65DN fluctuation dropping from 12 volts down about 9.5 volts and then rising to its present 19.8 volts. The DC reading changes occurred during a period of no spacecraft activity. All other power related and subsystem telemetry measurements are normal. The preliminary sequence and command generation products for VE-11 (Venus-Earth 11) earth encounter sequence were reviewed and approved by the Project on October 29. The Project GDS (Ground Data System) testing for Earth 1 continued with the successful completion of tests in the Madrid and Goldstone support configurations. The GDS tests are being conducted in conjunction with the DSN (Deep Space Network) Mission Readiness Tests (MRTs) to minimize Project scheduling requirements for DSN stations. Successful end-to-end real time data flow was completed for data rates/formats to be used during Earth 1 support. Non-real time interface products including magnetic tapes of imaging data for MIPL (Multimission Image Processing Lab) and Low rate Science for Data Records were collected and are in the process of being verified by those systems. A test is scheduled to validate the 26-meter uplink capability. ___ _____ ___ /_ /| /____/ \ /_ /| | | | | __ \ /| | | | Ron Baalke | baalke@mars.jpl.nasa.gov ___| | | | |__) |/ | | |___ Jet Propulsion Lab | baalke@jems.jpl.nasa.gov /___| | | | ___/ | |/__ /| M/S 301-355 | |_____|/ |_|/ |_____|/ Pasadena, CA 91109 | ------------------------------ End of SPACE Digest V12 #526 *******************
