No. 92 - Mission Progress
The spacecraft has gone through its closest approach to Earth on 18th of August configured at maximum bit rate of 228 kbps (with HGA2). The table below shows a chronology of the main activities in the reporting period:
| MET (Day) | Date | DOY | Main Activity |
| 642 | 12/08/07 | 224 | Routine Operations. Virtis fill state achieved 90%. |
| 643 | 13/08/07 | 225 | Routine Operations. S-Band Test via LGA over NNO. VIRTIS movie interrupted due to Hcool Mot Curr alarm. |
| 644 | 14/08/07 | 226 | Routine Operations. S-Band Test via LGA over NNO. Recovery of data gaps |
| 645 | 15/08/07 | 227 | Routine Operations. |
| 646 | 16/08/07 | 228 | Routine Operations. Command to swap PS not sent. All HK data and the associated command verifications lost. Pass finished at 12:00 for Cebreros maintenance. |
| 647 | 17/08/07 | 229 | Routine Operations. All Aspera commands failed execution. |
| 648 | 18/08/07 | 230 | Routine Operations. Next ASPERA observation CMDs (230:10:48:01) executed nominal. |
At the end of the last Cebreros pass in the reporting period (DOY 230, 15:00z) Venus Express was orbiting Venus at 43.1 million km from the Earth. The one-way signal travel time was 147 seconds.
Payload Activities
ASPERA
The instrument was operated as part of the routine plan.
MAG
The instrument was regularly operated as part of the routine plan.
PFS
No PFS operations were carried out this week.
SPICAV
The instrument was regularly operated as part of the routine plan.
