The European Space Agency’s Mars Express has created a remarkable three-dimensional picture of the region of Mars called Tiu Vallis, which was carved by flowing rivers millions of years ago.

Scientists coloured the photographs they had to show the changes in the height of the surface of the planet.

Water has carved recesses up to 2000 meters deep,  say the geologists who are from the Freie Universität Berlin and who helped to draft these images.

On the surface of many of the craters there is no sedimentary rock.

These craters arose as a result of asteroid activity when there was no water on Mars any more.

Mars Express snapped the photos during 10 flights across the Martian terrain. The photographed region is approximately 380 km in length.
