No. 182 - Mission Operations Report

Report for Period 3 May to 9 May 2009The Venus Express spacecraft and instruments performed nominally during this week. The dual launch of Herschel and Planck on 14 May has an impact on the Cebreros ground station passes, shortening them by 2-3 hours during about 10 days.

The table below shows a chronology of the main activities:

MET
(Day)
Date DOY Main Activity
1272 03/05/09 123 Communications pass over Cebreros
1273 04/05/09 124 Communications pass over Cebreros
1274 05/05/09 125 Communications pass over Cebreros.
Telemetry bit rate changed from 91kbps to 76 kbps
1275 06/05/09 126

Communications pass over Cebreros

1276 07/05/09 127

Pass shortened to allow pre-launch dress-rehearsal for Herschel and Planck

1277 08/05/09 128 Communications pass over Cebreros
1278 09/05/09 129 Communications pass over Cebreros

At the end of the last Cebreros pass in the reporting period (DOY 129) Venus Express was orbiting Venus at 72.9 million km from the Earth. The one-way signal travel time was 243 seconds.
