No. 107 - Mission Operations Update
11 November 2008
Report for Period 6 October to 31 October 2008
The reporting period covers four weeks of active cruise phase. An investigation was performed of a problem that had occurred with the COSIMA instrument during the asteroid Steins fly-by, focussing on the instrument's Target Manipulation Unit (TMU).
Spacecraft and ground segment performance during the reporting period have been nominal. Mission operations were conducted with the support of the ESA New Norcia (NNO) ground station and the NASA Goldstone DSN ground station (DSS).
At the end of the reporting period (DoY 305) Rosetta was at 451.26 million km from Earth (3.01 AU) and the one-way signal travel time was 1505 seconds. The distance to the Sun was 334.65 million km (2.23 AU).
The spacecraft is configured for low activity cruise. The check-out of the Radio science experiment will be executed in the next reporting period together with some investigation and recovery activities for the COSIMA and Lander instruments.
The spacecraft continues its fourth orbit around the Sun reaching aphelion on 17 December 2008 at a distance of 2.26 AU. It then heads back to Earth for the mission's last gravity assist and third Earth swing-by on 13 November 2009.
No special activities are planned for this conjunction phase during which short weekly passes will be taken.
