This is an anaglyph (3D) image of Tyrrhena Terra.

The High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express obtained images of the Tyrrhena Terra Impact region on Mars.

On 10 May 2007, the spacecraft was in orbit number 4294 when it snapped pictures of the region located at 18° South and 99° East with a ground resolution of approximately 15 metres per pixel.

The western part of the scene is dominated by a 35 kilometre-wide and approximately 1000 metre-deep impact crater with an extremely cliffy and chiseled edge.

Another, 18 kilometre-long and approximately 750 metre-deep impact crater, in all likelihood a ‘double impact crater’, is located south of the large crater. These 'double impact craters' develop when two objects, part of a binary, hit the surface almost simultaneously.

This anaglyph image was calculated by putting together data from the nadir channel and one stereo channel.
