Cassini Significant Event Report

For Week Ending 02/05/99


Spacecraft Status:


The most recent spacecraft status is from the DSN tracking pass on
Thursday, 02/04, over the Goldstone tracking station. The Cassini
spacecraft is in an excellent state of health and is operating 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 Tuesday, 02/02, TCM-6 (Trajectory Correction Maneuver) was successfully
uplinked to the Spacecraft, an SSR Pointer Reset was performed and Flight
Software Partition Maintenance was performed.


On Thursday, 02/04, TCM-6 executed with the Main Engine burn occurring at
12:00 PST with a duration of just under two minutes. Preliminary results
indicate this was a successful and very accurate TCM. After the TCM, a
High Water Mark Clear was performed.

Reset on 02/09. A ranging only pass will occur on Tuesday 02/09 into 02/10.



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.
