Cassini Weekly Significant Events for 03/14/02 - 03/20/02
The most recent spacecraft telemetry was acquired from the Goldstone tracking station on Wednesday, March 20. The Cassini spacecraft is in an excellent state of health and is operating normally. Information on the present position and speed of the Cassini spacecraft may be found on the "Present Position" web page.
Activities this week included two Radio and Plasma Wave Science (RPWS) High Frequency Receiver calibrations, and the Imaging Science Subsystem (ISS) Narrow and Wide Angle Cameras (NAC and WAC) going to sleep mode. Both the Ultraviolet Imaging Spectrograph (UVIS) and RPWS instruments were successfully loaded with new flight software, and the final round of tests for the new command system took place, with the Canberra Deep Space Communications Complex (DSCC) successfully uplinking a series of test commands to the Cassini spacecraft.
The Sequence Team has continued with the C32 sequence development process, with the Subsequence Generation Sequence Change Request meeting being held this week. No major changes have been identified for the C32 background sequence, and the detailed sequence generation is proceeding normally.
The C33 Science Planning Team cruise sequence development kicked off on Monday, March 18. This sequence starts the Space Science Cruise period.
In support of Saturn Tour planning, the Titan Orbiter Science Team (TOST) met last week to finish up the detailed integration of the Titan-9 encounter. The TOST also held a half-day meeting later in the week to resolve the Visual and Infrared Mapping Spectrometer (VIMS) issues arising out of the Titan-6/7 swap, which was a result of the latest Tour modifications made in order to manage Saturn ring plane crossings.
Mission Assurance presented a paper, "Managing Risk for Cassini During Mission Operations and Data Analysis" at a well-attended session of the IEEE Aerospace Conference, in Big Sky, Montana. In addition, Mission Assurance supported a JPL workshop entitled "Ensure Mission Success." This workshop brought together the various JPL flight projects in a discussion of operations practices to successfully manage mission risks.
