NASA Cassini Significant Events for 12/04/03 – 12/10/03

The most recent spacecraft telemetry was acquired from the Goldstone
tracking station on Monday, December 8. 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 located at .

On-board activities this week included transition from reaction wheels
to the reaction control subsystem, uplink of Probe pre-heating checkout
tests 1A and 2, execution of Probe test 1A with orbiter instruments in
sleep and muted, uplink of the Composite Infrared Spectrometer flight
software checkout, a Radio and Plasma Wave Science High Frequency
Receiver calibration, and uplink of an Ion and Neutral Mass Spectrometer
recovery mini-sequence to execute next week.

Deliveries were made for both the preliminary and official port 2 as
part of the Science Planning Team process for C44.

The European Space Agency began the Huygens Mission Delta Flight
Acceptance Review (FAR) with a kickoff meeting last week at the European
Space Research and Technology Centre in Noordwijk, Netherlands. The
overall purpose of the review is to examine the changes in the Huygens
mission that have been implemented since the FAR that was conducted six
months prior to launch. Specific objectives of the review are the
validation of the new mission scenario designed to recover from the
receiver anomaly, the re-validation of the entry and descent (with
respect to the revised atmosphere model), and the confirmation of the
readiness of operations preparations for the revised Huygens Mission.
The review team has split into three panels to focus on each of the
primary objectives. The panels will meet over the next six weeks to
review the documentation and prepare requests for further discussion.
There will be a final co-located set of panel meetings in early February
and the review will conclude with a board meeting on February 13.

The Navigation team completed the third segment of team test and
training. This segment included processing of the tracking data from
Saturn Orbit Insertion to Tb, the second Titan encounter. Both the
spacecraft and major satellite ephemeredes were estimated.

A Software Review/Certification Requirements meeting for Cosmic Dust
Analyzer v9.2 flight software (FSW) was held this week. The FSW has been
accepted to the project software library and approved for processing and
uplink in January as part of C42 sequence activities.

A number of delivery coordination meetings were held last week for
Telemetry, Tracking, Command & Data Management 28.1.1, Remote Terminal
Interface Unit V3.0 software, Electronic Command Request Form V1.1,
Cassini Operations Reference Encyclopedia 4.0, and E-Kernel Generation

The Cassini website has a new look. To comply with agency-wide portal
design specifications, the Cassini website has rolled out a new graphics
environment. Also new to the website are major content enhancements to
the kids’ section. To view the site go to:

Cassini is a cooperative project of NASA, the European Space Agency and
the Italian Space Agency. The Jet Propulsion Laboratory, a division of
the California Institute of Technology in Pasadena, Calif., manages the
Cassini mission for NASA’s Office of Space Science, Washington, D.C.
