No. 40 - Science Operations

Report for Period 6 August to 12 August 2006During 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:

At the end of the last Cebreros pass in the reporting period on DOY 224, Venus Express was orbiting Venus at 237 million km from the Earth. The one-way signal travel time was 789 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. Occultation observations with the USO un-muted took place on DOY 218, 220 and 223.

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
The planning of STP015 was completed on time. The pre-check of POR for STP016 did not reveal any anomaly.

Medium Term Planning
The planning of MTP-06 was completed successfully. MTP-06 does not include the conjunction operations; a specific plan will be generated for that period.

Future Milestones

Trajectory correction manoeuvres will be performed on 2006-230 and 2006-236.

Throughout the next week short term planning activities for CP16 will be completed, and the pre-checks of the CP17 will be performed. The processing of MTP6 inputs will continue.

An operational strategy for the upcoming solar conjunction phase in October/November 2006 will be developed throughout the coming weeks.
