No. 53 - End of Conjuntion Operations
The table below shows a chronology of the main activities in the reporting period:
| MET (Day) | Date | DOY | VPER# | Main Activity |
| 362 | 05/11/06 | 309 | 198 | Conjunction operations |
| 363 | 06/11/06 | 310 | 199 | Conjunction operations |
| 364 | 07/11/06 | 311 | 200 | Conjunction operations |
| 365 | 08/11/06 | 312 | 201 | Conjunction operations Increasing TM/TC bitrates |
| 366 | 09/11/06 | 313 | 202 | Configure S/C for routine operations, Dump S/C telemetry from conjunction period (1st part), Upload schedule to resume science operations |
| 367 | 10/11/06 | 314 | 203 | Dump S/C telemetry from conjunction period (2nd part) |
| 368 | 11/11/06 | 315 | 204 | Routine Mission operations |
At the end of the last Cebreros pass in the reporting period (DOY 315, 18:00z) Venus Express was orbiting Venus at 256 million km from the Earth. The one-way signal travel time was 852 seconds.
Science Update
The following set of images has been released since the previous status report.
13 November 2006
VIRTIS - Visible and Infrared Thermal Imaging Spectrometer
|
Date: 23 September 2006 Description: False-colour image of area close to the south pole imaged at 1.7 μm, revealing the differences in cloud cover thickness and the thermal emission coming through the clouds. |

Date: 29 July 2006 Description: Monochrome image of the south polar region imaged at 1.7 μm, showing the distinctive pattern of cloud wave structure at around 55° southern latitude. |

Payload Activities
ASPERA
Routine operation of the instrument was resumed on DOY 314.
MAG
Routine operation of the instrument was resumed on DOY 314.
PFS
The instrument is OFF and was not operated.
SPICAV
Routine operation of the instrument was resumed on DOY 314.
VeRA
The USO is nominally powered but muted. No RSI experiments were performed during the reporting period.
VIRTIS
Routine operation of the instrument was resumed on DOY 314.
A workaround to avoid HK bursts, which recently led to spacecraft safe modes, was tested and approved by the PI. After this the on-board execution of VIRTIS TCs was enabled again and the instrument was operated successfully in orbit 204.
VMC
Routine operation of the instrument was resumed on DOY 314.
Mission Planning
Short Term Planning
Operations of STP027 were executed successfully and the planning of STP028 was completed in time.
The pre-check of PORs for STP029 has been finished with success.
Medium Term Planning
MTP010 planning is on-going.
Long Term Planning
Discussions on the data amount produced by the movie observation, to be performed in April 2007, are ongoing.
Future Milestones
Swap from HGA1 to HGA2 in May 2007. An operational strategy to avoid VMC illumination is under discussion and has to be agreed with Astrium and Project.
