No. 63 - Earth Occultation Observations

Report for Period 21 January to 27 January 2007During the reporting period the mission operations have been conducted according to the plan. Science operations have been nominal. Radio science activities with the New Norcia ground station have been conducted as planned.

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

MET (Day) Date DOY VPER# Main Activity
439 21/01/07 021 275 Routine Mission Operations
440 22/01/07 022 276 Routine Mission Operations
441 23/01/07 023 277 Routine Mission Operations
442 24/01/07 024 278 Routine Mission Operations
443 25/01/07 025 279 Routine Mission Operations;
TM bitrate change
444 26/01/07 026 280 Routine Mission Operations
445 27/01/07 027 281 Routine Mission Operations

At the end of the last Cebreros pass in the reporting period (DOY 027, 17:00z) Venus Express was orbiting Venus at 229 million km from the Earth. The one-way signal travel time was 763 seconds.

Mission Planning

Short Term Planning
Operations of STP038 were executed successfully and the planning of STP039 was completed in time.

Long Term Planning
At the VMOC-VSOC planning telecom, it was decided that a new FECS will be produced this week, with updated pass times, and a new definition of the 'Start Dump' event (the current 3000 second margin will be substantially reduced). The FECS file, contains the list of the downlink and radio science opportunities from the available ground stations.


Future Milestones

The definition and testing of operations during quadrature is on-going; the next quadrature phase will start in May 2007.
