No. 158 - Cebreros Refurbishment26 Nov 2008 16:06 Report for Period 16 November to 22 November 2008 This reporting period marks the beginning of the Cebreros ground station downtime, which will be out of operations until 1 December 2008 for refurbishment activities. The New Norcia ground station is used for routine communication with the spacecraft during the Cebreros downtime. At the same time, radio science investigation (RSI) occultation observations are also performed during certain New Norcia passes, combining this activity with the routine communication tasks.
The telemetry bit rate has to be revised down to 114 kbps for communications over New Norcia, due to this station's lower link margin. During the reporting period VIRTIS was only operated in the visual channels. The table below shows a chronology of the main activities:
At the end of the last New Norcia pass in the reporting period (DOY 327) Venus Express was orbiting Venus at 159 million km from the Earth. The one-way signal travel time was 530.5 seconds. Payload ActivitiesASPERA MAG PFS SPICAV VeRA VIRTIS VMC Future Milestones
