No. 136 - End of Conjunction Phase Operations

Report for Period 15 June to 21 June 2008The reporting period covered the last days of solar conjunction phase operations (ending on 19 June), the reconfiguration of the solid state mass memory (SSMM) and the resume of science activities. Commanding tests and recording of open loop data continued until the exit from the conjunction phase.

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

MET (Day) Date DOY Main Activity
950 15/06/08 167 Commanding tests and reaction wheel off-loading (WOL) during the pass
951 16/06/08 168 Commanding tests and WOL during the pass
952 17/06/08 169 Commanding tests and WOL during the pass
953 18/06/08 170 Commanding tests and WOL during the pass
954 19/06/08 171 Solar conjunction exit operations.
Dump of data recorded on-board during solar conjunction phase.
Bit rate changed to 57 kbps
955 20/06/08 172 SSMM reconfiguration
956 21/06/08 173 Resume of science activities

At the end of the last Cebreros pass in the reporting period (DOY 173) Venus Express was orbiting Venus at 258.6 million km from the Earth. The one-way signal travel time was 863 seconds.
