Ice-covered region on Mars
This false-colour nadir image, taken by HRSC onboard Mars Express on 15 December 2004, shows a relatively thin cover of what is likely to be water snow over smooth plains. A small impact crater is visible in the centre-right of the image. Snow over dark areas has probably been blown away by strong winds, as the numerous dune layered deposits seem to indicate.
The image is centred at 78.34 degrees North and 117.35 East and the ground resolution is 40 meters per pixel.
