Hephaestus Fossae ortho-image

June 17, 2009
This image of Hephaestus Fossae was obtained by ESA's Mars Express orbiter on 28 December 2007. The region is dotted with craters and channel systems and lies at about 21°N and 126°E on the Red Planet. Named after the Greek god of fire, Hephaestus Fossae extends for more than 600 km on the western flank of Elysium Mons in the Utopia Planitia region.

This ortho-image was rectified using elevation data derived from a high-resolution Digital Terrain Model, or DTM (obtained from HRSC data), such that distortions introduced during imaging are corrected. Such an image can be used to derive maps. Elevation data from the DTM has been colour-coded and overlain on the ortho-image so that elevation data and the image itself are displayed in a single scene.

The scale is in metres.
