No. 184 - Mission Operations Report

Report for Period 17 May to 23 May 2009The Venus Express spacecraft and instruments performed nominally during this week. Use of the Cebreros ground station was required during the launch and early orbit phase (LEOP) of the Herschel and Planck missions, which were launched on 14 May. This has had an impact on a few communication passes for Venus Express that are performed daily with the Cebreros ground station.

The Herschel and Planck LEOP went very smooth and was completed earlier than scheduled. Cebreros communication passes for Venus Express were restored to nominal pass times from 21 May onwards.

The table below shows a chronology of the main activities:

MET
(Day)
Date DOY Main Activity
1286 17/05/09 137

Cebreros communications pass shortened for Herschel and Planck LEOP

1287 18/05/09 138

Cebreros communications pass shortened for Herschel and Planck LEOP

1288 19/05/09 139

Cebreros communications pass shortened for Herschel and Planck LEOP

1289 20/05/09 140

Cebreros communications pass shortened for Herschel and Planck LEOP

1290 21/05/09 141

Communications pass over Cebreros.
Telemetry bit rate changed from 57 kbps to 45 kbps

1291 22/05/09 142

Communications pass over Cebreros

1292 23/05/09 143

Communications pass over Cebreros, shortened at the end by 1.5 hours for Mars Express

At the end of the last Cebreros pass in the reporting period (DOY 143) Venus Express was orbiting Venus at 89 million km from the Earth. The one-way signal travel time was 297 seconds.
