    >
    >The most recent spacecraft telemetry was acquired from the Goldstone
    >tracking station on Monday, February 9. 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
    >http://saturn.jpl.nasa.gov/operations/present-position.cfm .
    >
    >The Radio and Plasma Wave Science (RPWS) and Cassini Plasma Spectrometer
    >(CAPS) solar wind observations concluded this week. Cassini has begun
    >taking
    >data for the first color Saturn and ring approach movies. Ultraviolet
    >mosaics of the Saturn magnetosphere continue to map neutral and ion photon
    >emissions to derive the distribution and density of atomic and molecular
    >species.
    >
    >Additional on board activities included uplink and execution of power cycle
    >commands to perform a Magnetospheric Imaging Instrument (MIMI) Low Energy
    >Magnetospheric Measurement Subsystem recovery, execution of the Visual and
    >Infrared Mapping Spectrometer (VIMS) flight software checkout, a Cassini
    >Plasma Spectrometer configuration, calibration and master instrument
    >expanded block load for participation in solar wind survey observations,
    >uplink and execution of Ion and Neutral Mass Spectrometer (INMS) diagnostic
    >flight software, deactivation and deregistration of the INMS memory dump
    >mini-sequence, RPWS high frequency receiver calibrations, a reaction wheel
    >unload, and clearing of the ACS high water marks.
    >
    >The Navigation team acquired 15 out of 16 scheduled optical navigation
    >(OPNAV) images of the small Saturnian satellites this week. Spacecraft
    >pointing for all received frames was excellent. These were the first sets
    >of
    >images dedicated towards optical navigation of Cassini. Previous OPNAVs
    >were performed only for calibration purposes.
    >
    >The C43 Final Sequence Integration and Validation (FSIV) Sequence Change
    >Request approval meeting was held this week with sequence approval
    >scheduled
    >for Thursday. The Preliminary Sequence Integration and Validation (PSIV)
    >sub-phase has begun for approach science sequence C44.
    >
    >A wrap up meeting was held for Science Operations Plan (SOP) implementation
    >of tour sequences S21, and S22. These sequences will be archived until
    >February of 2006 when the S21 aftermarket process begins. Preliminary port
    >1
    >deliveries were made for SOP Implementation of tour sequences S23 and S24.
    >
    >Spacecraft Operations successfully completed a dry run rehearsal of the
    >Probe Relay demonstration in the ITL last week. This week, an internal peer
    >review was held for this activity. The actual demonstration will execute
    >on
    >the spacecraft in February and March of this year. The Probe Relay Demo
    >simulates the actual Relay sequence to be used in January 2005 when the
    >Huygens Probe reaches Titan.
    >
    >Cassini and other JPL personnel supported the co-located panel meetings for
    >the Huygens Mission delta Flight Acceptance Review (FAR) at Alcatel. The
    >three panels went through all the Review Item Discrepancies (RIDs)
    >submitted
    >by the reviewers. The RIDs were processed with either a closure response or
    >further action was assigned. The follow on actions were to either clarify
    >points in certain documents, perform additional confirming analysis or
    >testing. Each panel has prepared reports that will be submitted to the
    >final
    >board meeting being held on February 13.
    >
    >The Cassini Radio Science Task Lead presented a briefing to the Program
    >Manager and Cassini staff on the status of the anomaly of the Ka-band
    >Translator (KaT). A representative from Alenia Spazio, the manufacturer of
    >the KaT, traveled from Italy to participate. The presenters gave the
    >background and history of the anomaly as well as the current plans for
    >attempted recovery, probably starting in mid March.
    >
    >VIMS instrument personnel attended a team meeting in Tucson, Arizona.
    >Topics of discussion included tour operations and plans.
    >
    >So far at least 295 VIMS data cubes have been received during C42. Data
    >from last weeks VIMS flight software checkout has been initially processed.
    >This version 8.1 upgrade was to add the capability to spectrally sum the
    >data. The software appears to have performed properly, and the spectrums
    >summed as expected
    >
    >A delivery coordination meeting was held for the Command Database version
    >D10C.
    >
    >Cassini presentations were given this week at career day events for the
    >American Association of University Women, and to 250 students at Bell
    >Gardens High School in Montebello, California.
    >
    >The European Space Agency has released the February 2004 Huygens Status
    >Report. Topics include the revised mission implementation, and Delta
    >Flight
    >Acceptance Review status. For more information go to:
