    No. 44 - Science Operations

    18 Sep 2006 09:11

    Report for Period 3 September to 9 September 2006

    During the reporting period the mission operations have been conducted according to the plan. The ground and the space segment performance have been nominal.

    The table below shows a chronology of the main activities in the reporting period:

    MET (Day) Date DOY VPER# Main Activity
    299 03/09/06 246 135 Routine science operations
    300 04/09/06 247 136 Routine science operations
    CEB XSSA test
    301 05/09/06 248 137 Routine science operations
    302 06/09/06 249 138 Routine science operations
    CEB XSSA test
    303 07/09/06 250 139 Routine science operations
    PM3 RAM dump in support of Safe Mode investigation
    304 08/09/06 251 140 Routine science operations
    SPS PIT for DSS-65
    305 09/09/06 252 141 Routine science operations

    At the end of the last Cebreros pass in the reporting period (DOY 252, 16:00) Venus Express was orbiting Venus at 249 million km from the Earth. The one-way signal travel time was 830 seconds.

    Payload Activities

    ASPERA
    The instrument is regularly operated as part of the routine plan.

    MAG
    The instrument is regularly operated as part of the routine plan.

    PFS
    The instrument is currently OFF and is not included in the routine planning. Next PFS tests in Venus pointing attitude are planned for the first 4 orbits of MTP 6 (24-27 September 2006)

    SPICAV
    The instrument is regularly operated as part of the routine plan.

    VeRA
    The USO is nominally powered but muted.

    VIRTIS
    The instrument is regularly operated as part of the routine plan.

    VMC
    The instrument is regularly operated as part of the routine plan.

    Mission Planning

    Short Term Planning
    Operations of STP18 have been completed successfully and the planning of STP19 was completed in time. A pre-check of the payload requests for STP20 was also successful.

    Long Term Planning
    DSN provided first cleared Station Allocation File (SAF) for week 41 (VERA solar corona passes).

    A proposal for New Norcia station booking for OCC-3 and GRA-2 campaign in May-June 2007 has been provided to Rosetta and Mars Express for iteration.

    Future Milestones

    Throughout the next week short term planning for CP20 and pre-checks for CP21 will commence.

    An operational strategy for the upcoming solar conjunction phase in October/November 2006 is being further iterated.
