Report for Period 21 September to 27 September 2008 Nominal operations were conducted during the reporting period. The batteries continue to perform nominally during the eclipse season that started on 19 September. As part of the routine operations, the voltage and current evolution is closely monitored during the eclipses. The eclipse season will last until 11 November.
The table below shows a chronology of the main activities: | MET (Day) | Date | DOY | Main Activity | | 1048 | 21/09/08 | 265 | Routine Operations | | 1049 | 22/09/08 | 266 | Routine Operations | | 1050 | 23/09/08 | 267 | Routine Operations | | 1051 | 24/09/08 | 268 | Routine Operations | | 1052 | 25/09/08 | 269 | Routine Operations | | 1053 | 26/09/08 | 270 | Routine Operations | | 1054 | 27/09/08 | 271 | Routine Operations | At the end of the last Cebreros pass in the reporting period (DOY 271) Venus Express was orbiting Venus at 210.6 million km from the Earth. The one-way signal travel time was 702 seconds. Payload Activities ASPERA
The instrument was regularly operated as part of the routine plan. MAG
The instrument was regularly operated as part of the routine plan. PFS
The instrument was not operated during the reporting period. SPICAV
The instrument was regularly operated as part of the routine plan. VeRA
No measurements were taken during the reporting period. VIRTIS
The instrument was regularly operated as part of the routine plan. VMC
The instrument was regularly operated as part of the routine plan. Future Milestones - A Trajectory Control Manoeuvre is planned for Sunday 28 September. This manoeuvre constitutes a phase correction and is intended to keep the phasing of Venus Express in its orbit in sync with mission operations from ground.
- High gain antenna (HGA1) S-band carrier power test is planned for 15 December 2008
- Next quadrature phase will start on 19 December 2008
