All activities have been conducted according to the plan without major problems except for the Rosina RTOF (Reflectron type Time Of Flight mass spectrometer) sensor which is showing anomalous behaviour already seen earlier. Jupiter observations with the ALICE instrument will continue till May.

The navigation campaign after the Mars Swing-by is continuing with the preparation of the Deep Space Manoeuvre 3 planned for 26 April 2007.

At the end of the reporting period (DOY 110) Rosetta was at 276.7 million km from Earth (1.84 AU; one-way signal travel time was 15 minutes 23 seconds). The distance to the Sun was 234.4 million Km (1.56 AU).
