Cassini Significant Event Report

For Week Ending 10/09/98

Spacecraft Status:

The most recent Spacecraft status is from the DSN tracking pass on
Wednesday, 10/07, over Goldstone. The Cassini spacecraft is in an
excellent state of health and is executing the C10 sequence nominally.
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:

Monday, 10/05, a housekeeping activity was performed which reads out a set
of AACS Attitude Estimator (ATE) measurements not available in regular
engineering telemetry.

Wednesday, 10/07, four activities took place: the Solid State Recorder
(SSR) record and playback pointers were reset; a CDS Flight Software Patch
was sent to the spacecraft to avoid backup CDS resets resulting from
science telemetry mode transitions; uplink was performed of the SAF Alt
Mode Table, which loads 3 alternate versions of where science data are
collected from the instruments in the SAF 248 telemetry mode in
preparation for Instrument Checkout; and the AACS High Watermarks were
cleared.

Upcoming events:

Activities scheduled for the week of 10/09 - 10/15 include:

SSR FSW Partition Maintenance on 10/10, Periodic Instrument Maintenance on
10/11, and an SSR Pointer Reset on 10/14. Ranging passes occur on 10/13
and 10/14.

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.
