Cassini Significant Event Report
For Week Ending 09/18/98
The most recent Spacecraft status is from the DSN tracking pass on Tuesday, 09/15, 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:
On Monday, 09/14, routine maintenance was performed on the SSR flight software partitions, and a housekeeping activity was
performed which reads out a set of AACS Attitude Estimator measurements not available in regular engineering telemetry.
On Tuesday, 09/15, a Remote Engineering Unit MRO for the Main Engine Cover was performed. This MRO is a test for an
operation to be used for the Deep Space Maneuver. After the MRO, the Solid State Recorder (SSR) record and playback pointers
Activities scheduled for the week of 09/18 - 09/24 include a Periodic Engineering Maintenance, AACS High Watermark Clear, and
SSR Pointer Reset on 09/23, and a Ranging Pass on 09/24.
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.
