The 3D images from the High Resolution Stereo Camera (HRSC) on the ESA Mars Express probe help simulate a flight over the martian surface.
Hebes Chasma is an enclosed, almost 8000 metre-deep trough in the northern-most part of Valles Marineris, the 3000-km long "Grand Canyon of Mars" and this video, in false (exaggerated) colour shows a four-minute flight through the valley.
The origin of Hebes Chasma is thought to be connected to the near-by Tharsis Region, which was uplifted in the course of intense volcanism. The uplift created tremendous amounts of stress in the crust forming a series of faults oriented radially.
