If there is still interest in specific objects or areas, why don't we know what's being looked at? What bothers me the most is that once the fanfair of a big encounter is over everybody forgets about the whole project. Engineers stop talking, and Reporters stop reporting. Yes many people lose interest after "the big event", but a lot of us don't. It seems like a waste of good "PR" for NASA to stop talking. # SOAP BOX OFF FFFFEW! I feel better now.

I recall reading a book by Jacques Cousteau describing his experiences with the newly invented SCUBA-gear. He once went down to about 30 meters' depth with pure oxygen tubes, at which point he fainted. I don't recall exactly why this happened. In any event, he decided (wisely :-) to rely on mixed-gas tubes in latter dives. _______________________________________________________________________________ | | | | |\ | | /|\ | John Kallen Computer: kom-pyu'-ter (n) a | |\ \|/ \| * |/ | |/| | | PoBox 11215 device for generating errors | |\ /|\ |\ * |\ | | | | Stanford CA 94309 speedily and unpredictably. _|_|___|___|____|_\|___|__|__|_jkl@neon.stanford.edu___________________________ ------------------------------ Date: 16 May 90 15:32:10 GMT From: usc!elroy.jpl.nasa.gov!jato!mars.jpl.nasa.gov!baalke@ucsd.edu (Ron Baalke) Subject: Voyager Update - 05/16/90 Voyager Mission Status Report May 16, 1990 Voyager 1 The Voyager 1 spacecraft continues to collect routine cruise science data. On May 4 a six hour Ultraviolet Spectrometer (UVS) observation of HD 217675 was executed; there was no Deep Space Network (DSN) 70 meter antenna support available therefore the downlink of this observation was not received. On May 7 a frame of Plasma Wave (PWS) data was recorded for future playback. A Digital Tape Recorder (DTR) Tape Position (TAPPOS) slew was executed in the low rate for the first time on May 8. The tape position arrived at was as expected however, a speed reduction of 2% was observed from the nominal 7.2 kbps slew rate. This is a known idiosyncrasy of the DTR when operating without the 7.2 kbps reference signal normally provided by the Flight Data Subsystem (FDS). This reference signal is not provided when the DTR is in the Slew mode or when operating a non-record or playback data mode. Also on May 8 Playback #2, containing spacecraft roll maneuver (MAGROL) data, was executed using the Plasma Wave Subsystem Data Playback (PWSPB) Block Routine (BR9). This was the first execution of this block and the spacecraft performance was nominal. There was however, a maximum of -0.5 db downlink degradation introduced into the DSS 63/65 array (70 meter and 34 meter antennas in Spain arrayed together) due to a problem with the DSS 63 sub-reflector being fixed at the 35 degree position. The data quality appeared to be acceptable for the playback. Voyager 2 The Voyager 2 spacecraft also continues to collect routine cruise science data. On May 7 and May 10 eleven hour UVS observations of Markarian 509 were executed by the spacecraft; there was no 70 meter DSN support available for either observation therefore downlink of this data was not received. On May 8 a frame of PWS data was recorded for future playback. A Plasma instrument calibration (PLSCAL) was executed by the spacecraft on May 9. Performance of the calibration was nominal and no problems were experienced. The memory compare process has been completed on data received from the FDS memory read-out performed on April 25. The compare indicates that the FDS memory contents are as expected. Spacecraft performance for all of the sequenced activity during this report period has been nominal.
