This image composite is based on near-infrared, green and near-ultra-violet colour information obtained by the OSIRIS Narrow Angle Camera. At the southern part of the planet, the southern spring polar cap is clearly seen. At this time of the Martian year, a large fraction of Mars' atmosphere is evaporating from the southern polar cap and will migrate to the northern polar cap during nothern winter. Over most of the Martian disk one can see large cloud systems.
The image was acquired on 24 February at 19:28 CET from a distance of about 240 000 km; image resolution is about 5 km/pixel. Higher resolution images of Mars will be made available later.
