The European Space Agency’s (ESA) Mars Express has offered up a high-resolution photo of a river-like structure on Mars. The spacecraft used its high-resolution stereo camera last year to snap an image of Reull Vallis on the Red Planet.
Reull Vallis is a river-like structure believed to have formed when running water flowed in the distant martian past.
The ancient river bed cuts a steep-sided channel through the Promethei Terra Highlands before it runs towards the floor of the Hellas basin.
