This image of Hephaestus Fossae was obtained on 28 December 2007 by the High-Resolution Stereo Camera (HRSC) operated by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) on board the European Space Agency’s Mars Express orbiter. The region is dotted with craters and channel systems and lies at about 21 degrees north and 126 degrees east on the Red Planet. Named after the Greek god of fire, Hephaestus Fossae extends for more than 600 kilometres on the western flank of Elysium Mons in the Utopia Planitia region.

The surface is mostly smooth, and is covered by several small impact craters measuring 800 to 2800 metres in diameter. Smaller craters are scattered across the entire region. The left side of the image shows a large impact crater measuring 20 kilometres in diameter. Covering an area of approximately 150 square kilometres, a crater of this size on Earth could contain cities such as Bonn or Kiel. In contrast to the smaller craters, it shows a blanket of ejecta with flow forms surrounding the rim.
