Trough in Hellas Chaos

Close-up of a trough-like depression that runs in an east–west direction through Hellas Chaos on the floor of the vast Hellas Basin in the southern hemisphere of Mars. The trough is punctuated with small raised knobs of rough-textured material.

This region was imaged by the High Resolution StereoCamera on ESA’s Mars Express on 23 January 2014 during orbit 12 785. The main image is centred on 46ºS / 69ºE with a ground resolution of about 18 m per pixel.
