Anaglyph images can be created from the nadir channel of the High Resolution Stereo Camera (HRSC), which looks vertically down at Mars, and one of the four stereo channels, which are directed obliquely towards the surface. Using red/blue (cyan) or red/green glasses gives a three-dimensional impression of the landscape. North is to the right in the image. The high resolution of 16 metres per pixel enables even small differences in altitude to be seen, for example in the deposits that the ice flow (glacier) have left behind in Reull Vallis, the striking valley system in the centre of the image, or in the surrounding mountains and craters.
As a joint undertaking by DLR, ESA and FU Berlin, the Mars Express HRSC images are published under a Creative Commons licence since December 2014: ESA/DLR/FU Berlin, CC BY-SA 3.0 IGO. This licence will also apply to all HRSC images released to date.
