ESA Venus Express Status Report: No. 102

Status Report From: ESA Venus Express Mission
Posted: Wednesday, November 21, 2007

image 29 Oct 2007 12:00 Report for the Period 21 October to 27 October 2007

Following last week's entry in Quadrature phase, the activities during this week cover routine operations in Quadrature. These operations are severely constrained due to the special thermal restrictions that apply during Quadrature phase.

Preparations for the upcoming HGA swap were completed this week. All commands for the swap were loaded during the pass on 25 October, set for execution before AOS on 29 October.

VIRTIS operations remained disabled during this period. The rest of observations took place routinely during this reporting period.

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


MET (Day) Date DOY Main Activity
712 21/10/07 294 Routine operations
713 22/10/07 295 Routine operations. TM bit rate cahnged to 38 kpbs
714 23/10/07 296 Routine Operations. Station failure affected dumps.
715 24/10/07 297 Routine Operations
716 25/10/07 298 Routine Operations. Uplink of HGA Swap TCs.
717 26/10/07 299 Routine Operations & switch to quadrature operations
718 27/10/07 300 Pass skipped for cooldown before science ops

At the end of the last Cebreros pass in the reporting period (DOY 300, 13:00z) Venus Express was orbiting Venus at 109.5 million km from the Earth. The one-way signal travel time was 365 seconds.
