Significant Event Report for Week Ending 9/11/1998

Cassini Significant Event Report

For Week Ending 09/11/98

Program Level Items:

The monthly Cassini Program status report to NASA Headquarters was held on 9/09 via videocon. A reorganization of the Cassini
Program was announced on 9/08, effective immediately.

Spacecraft Status:

The most recent Spacecraft status is from the DSN tracking pass on Tuesday, 09/08, over Madrid. The Cassini spacecraft is in an
excellent state of health and is executing the C9 sequence nominally. The C9 sequence will complete on 9/13, at which point the C10
sequence will begin. 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, 09/07, the C10 sequence was uplinked to the spacecraft as scheduled.

On Wednesday, 09/09, the Solid State Recorder (SSR) record and playback pointers were reset. This housekeeping activity, done
approximately weekly, maximizes the amount of time that recorded engineering data is available for playback to the ground should an
anomaly occur on the spacecraft.

Upcoming events:

Activities scheduled for the week of 09/11 - 09/17 include: Ranging Pass (09/12), SSR Flight Software Partition Maintenance and
AACS ATE MRO (09/14), Remote Engineering Unit MRO for Main Engine Cover (Test of Procedure) and SSR Pointer Reset
(09/15), Ranging Pass (09/16).

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.
