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.

Tyrrhena Terra is part of the ancient, heavily cratered southern Martian highlands. The region is located north of Hellas Planitia, the largest impact basin on Mars. The image scene exhibits three impact craters, located at the eastern border of Tyrrhena Terra with Hesperia Planum.


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

The rim rises up to 400 metres above the surrounding plain. The crater is surrounded by multiple layers of material that was ejected during the impact. These so called ’ejecta blankets’ spread up to 50 kilometres around the crater. Their round, lobate appearance hints at possible ice- and water-rich subsurface material.

The High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express obtained images of this region on 10 May 2007.

This perspective view has been calculated from the Digital Terrain Model derived from the HRSC stereo channels.

The raised feature in the centre of the crater most likely originated from the elastic rebound of compressed subsurface material after the impact. This is comparable to what happens when a drop of water hits a puddle.

This view has been derived from the nadir channel which provides the highest level of detail. The Sun illuminates the scene from the south-west (from top-left in the image).


 
This image provides a persective view of Tyrrhena Terra.

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.

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.
