No. 51 - Ongoing Monitoring in Cruise Mode
23 November 2005 13:02Report for Period 28 October to 18 November 2005
The reporting period covers three weeks of passive cruise, for monitoring and minor maintenance activities.
On the spacecraft subsystems side, only minimum "keep-alive" activities were executed (one wheel offloading every 2 weeks), due to the uncertainty in future ground station coverage as a consequence of the Venus Express launch delay.
No operations were performed on the payload, which is completely inactive, with the exception of SREM, measuring in the background in accumulation mode. On 3 November the OSIRIS CCD decontamination heaters were re-activated.
A total of 3 New Norcia passes of about 7 hours commanding duration were taken over the reporting period.
At the end of the reporting period (DOY 322) Rosetta was at 297 million kilometres from the Earth (1.98 AU; one-way signal travel time was 16 minutes 29 seconds). The distance to Sun was 261 million kilometres (1.74 AU).
