Cassini Significant Event Report

For Week Ending 11/06/98

Spacecraft Status:


The most recent Spacecraft status is from the DSN tracking pass on
Wednesday, 11/04, over the Goldstone tracking station. The Cassini
spacecraft is in an excellent state of health and is executing the C10
sequence normally. The speed of the spacecraft can be viewed on the
"Where is Cassini Now?"
web page (http://saturn.jpl.nasa.gov/operations/present-position.cfm).


Spacecraft Activity Summary:


On Monday, 11/02, three activities were performed: the Delta-V Estimator
Flight Software Update was sent up to the spacecraft, the Solid State
Recorder (SSR) record and playback pointers were reset, and the AACS High
Water marks were cleared.


On Tuesday, 11/03, Part 1 of the SSR-A Power Off was performed. Powering
off the SSR will enhance the overall life expectancy of the unit. Part one
consisted primarily of a complete memory test prior to the power off
commands.


On Wednesday, 11/04, Part two of the SSR-A Power Off was performed and the
VIMS Decontamination Heaters were powered up for a 24 hour period.


Upcoming events:


Activities scheduled for the week of 11/06-11/12 include SSR FSW Partition
Maintenance on 11/06, uplink of the C11 sequence on 11/07, and AACS
Attitude Estimator Memory Readout and SSR Pointer Reset on 11/09.



Additional information about Cassini-Huygens is online at http://saturn.jpl.nasa.gov.


Cassini will begin orbiting Saturn on July 1, 2004, and release its piggybacked Huygens probe about six months later for descent through the thick atmosphere of the moon Titan. Cassini-Huygens is a cooperative mission of NASA, the European Space Agency and the Italian Space Agency. JPL, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Office of Space Science, Washington, D.C.
