Cassini Significant Event Report

For Week Ending 10/30/98

Spacecraft Status:


The most recent Spacecraft status is from the DSN tracking pass on
Monday,10/26, 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, 10/26, three activities were performed. The Remote Engineering
Unit Memory Read Out (MRO) for the Main Engine Cover was combined with
Real-time Engineering Mode (RTE)158 in a final test for their use in
support of the Deep Space Maneuver scheduled for 12/3/98.


This was followed by a housekeeping activity which reads out a set of AACS
Attitude Estimator (ATE) measurements not available in regular engineering
telemetry. Finally, routine maintenance was performed on the Solid State
Recorder (SSR) flight software partitions.

Upcoming events:


Activities scheduled for the week of 10/30 - 11/05 include the Delta-V
Estimator Flight Software Update, SSR Pointer Reset, and AACS High Water
Mark Clear on 11/02, and SSR-A Power Off parts 1 & 2 and Power On VIMS
Decontamination Heaters on 11/03, 04. Ranging passes are scheduled for
10/30 and 11/03.



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.
