No. 7 - Ongoing NEC Activities

Report for Period 02 December to 08 December 2005During the reporting period all the activities for the Near Earth Commissioning of theinstruments have been conducted according to the plan. The multi-instrument pointing scenarioactivities have been successfully concluded and the PFS instrument has been switched on forthe first time.

The ground behaviour has been nominal throughout the reporting period. 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 (DOY 342, 19:00) Venus Express was at 7.3 million km from the Earth, 142.4 million km from the Sun, and 54.3 million km from Venus. The one-way signal travel time was 24 seconds.

Payload Activities

ASPERA
The instrument is currently OFF and will be activated for the first time on DoY 343.

MAG
The instrument is permanently ON till the end of the NECP. During the pointing scenario some mode transitions have been successfully commanded.

PFS
The instrument has activated for the first time on DoY 338.

SPICAV
The instrument performed nominally also on DoY 336 (Stray Light test 2). Science data is being processed by the PI team.

VeRA
The USO is permanently kept powered since DoY 315 to allow VeRA commissioning activities on DoY 344.

VIRTIS
The instrument has been activated as part of the pointing scenario on DoY 336 (Stray Light test 2), 337 (Alignment raster), and 338 (Alignment off-pointing). Science data is being processed by the PI team.

VMC
The instrument has been activated as part of the pointing scenario on DoY 336 (Stray Light test 2) and 338 (Alignment off-pointing). Science data is being processed by the PI team.

Future Activities

Payload Commissioning will now continue with the functional test of ASPERA and then with the interference test. This will mark the end of the NECP.
