Ausonia Mensa

March 1, 2006

This image, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, shows the Ausonia Mensa massif on Mars.

The HRSC on ESA's Mars Express obtained this image on May 17, 2005, during orbit 506 with a ground resolution of approximately 37.6 metres per pixel. The perspective view shows the region of Hesperia Planum, containing the massif, at approximately 30.3° South and 97.8° East. This view is looking south-east.

Ausonia Mensa is a large remnant mountain with several impact craters, rising above basaltic sheet layers. The mountain stretches over an area of about 98 kilometres by 48 kilometres and has an elevation of 3700 metres.

A large crater, approximately 7.5 kilometres in diameter and 870 metres deep, has been partially filled with sediment. The northern flank of the crater is broken by a large gully caused by erosion.
