No. 135 - Conjunction Phase Operations
The table below shows a chronology of the main activities in the reporting period:
| MET (Day) | Date | DOY | Main Activity |
| 943 | 08/06/08 | 160 | No contact with the spacecraft |
| 944 | 09/06/08 | 161 | No contact with the spacecraft |
| 945 | 10/06/08 | 162 | No contact with the spacecraft |
| 946 | 11/06/08 | 163 | No contact with the spacecraft |
| 947 | 12/06/08 | 164 | No telemetry (TM) processed during the entire pass, due to signal noise at New Norcia (also from effects of Sun scintillation on a low bit rate signal) |
| 948 | 13/06/08 | 165 | Reduced conjunction commanding test was commanded. Some TM instability |
| 949 | 14/06/08 | 166 | Stable telemetry received 1:30 after acquisition of signal. All activities of the pass accomplished |
At the end of the last Cebreros pass in the reporting period (DOY 166) Venus Express was orbiting Venus at 259.5 million km from the Earth. The one-way signal travel time was 865 seconds.
