No. 99 - Switch to Active Cruise Mode21 Jul 2008 13:39 Report for Period 7 June to 4 July 2008 On 1 July 2008, DoY 183, Rosetta was taken out of Near Sun Hibernation Mode (NSHM) and reconfigured to Active Cruise Mode in preparation of the asteroid Steins fly-by phase.
Operations during the reporting period have been nominal and preparation of the spacecraft for the active payload check-out 8 (PC8) has started. This activity will keep the mission control team fully engaged with commissioning type activities for four consecutive weeks. A total of eight New Norcia (NNO) ground station passes were taken during this reporting period with nominal performance.
At the end of the reporting period (DoY 186) Rosetta was at 220 million km from Earth (1.47 AU) and the one-way signal travel time was 734 seconds. The distance to the Sun was 287 million km (1.92 AU).

The payload check-out 8 will last four weeks. This will be followed by the optical navigation campaign required for the asteroid fly-by. This campaign will include imaging by the navigation camera (NAVCAM) and by the OSIRIS instrument.
