ESA Shares Images of Reull Vallis, a River-like Structure on Mars

Posted on January 18, 2013

The European Space Agency has shared new images of the Reull Vallis, a river-like structure on Mars. The images were taken with the high-resolution stereo camera on the ESA's Mars Express.

The ESA says the Reull Vallis is "believed to have formed when running water flowed in the distant martian past." The channel runs for about 1500 kilometers (932 miles). The portion of the channel captured by the Mars Express in the above image is 7 kilometers wide and 300 meters deep.

More images of the Reull Vallis, including downloadable hi-res images and a 3D image can be found here.
