Mission:Mars Express

Instrument: HRSC: High-Resolution Stereo Camera.

The High-Resolution Stereo Camera (HRSC) on board ESA’s Mars Express has returned images of Echus Chasma, one of the largest water source regions on the Red Planet. Echus Chasma is the source region of Kasei Valles, which extends 3000 km to the north. The data was acquired on 25 September 2005. The pictures are centered at about 1° north and 278° east and have a ground resolution of approximately 17 m/pixel.

The dark material shows a network of light-colored, incised valleys that look similar to drainage networks known on Earth. It is still debated whether the valleys originate from precipitation, groundwater springs or liquid or magma flows on the surface.
