OSIRIS data from the Rosetta Mars flyby in context with other missions

Abstract : In this Paper we will present the imaging data acquired by the OSIRIS [1] instrument on board the ESA mission Rosetta during it's swing-by maneuver around February 25th, 2007 on the way to Comet 67P/Churyumov-Gerasimenko in context with corresponding data sets acquired by other missions during the period of the flyby, such as Mars Express and the Mars Reconnaissance Orbiter . Despite the long time that has passed since the observations, only few studies based on the data from the wide- (WAC) and narrow- (NAC) angle camera systems of OSIRIS have been published to date (see for example [2]). The OSIRIS images provide a global view of Mars from the UV (245 nm) over the full visible range to the near IR (1000 nm). The image acquisition started at February 24 around 18:00 UTC from a distance of about 260.000 km and continued until 04:51 UTC on February 25 to a distance of 105.000 km. During the Closest Approach to the Planet at 01:54 UTC on February 25 at a distance of 250 km. OSIRIS has imaged parts of the Martian surface and atmosphere up to resolutions of about 5km/pixel and captured many details on the surface, as well as several clouds and dust in the atmosphere.
