    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.
