OSIRIS collected spectacular images of Mars during the Rosetta flyby
An important observing opportunity of Osiris, before Rosetta arrives at 67P/Churyumov-Gerasimenko in 2014, is the Mars swing-by. Rosetta requires the Mars flyby to gain acceleration on a complicated trajectory. OSIRIS was actived during this close fly-by of Mars, and acquired beautiful images of the red planet on 24 February.

Due to the unique dynamic range and the filters of OSIRIS, new valuable information about Mars is expected. Researchers from the OSIRIS Team (PI: Uwe Keller from the Max Planck Institute for Solar System Research (MPS)) are currently working on the analysis of the data.
The images above were acquired on 24 February at 19:28 CET from a distance of about 240 000 km; image resolution is about 5 km/pixel. At closest approach, Rosetta passes the Martian surface at distance of only 250 km.
