New photos from European Mars orbiter show dynamic, volcanic Red Planet terrain

This image from ESA’s Mars Express spacecraft shows the Acheron Fossae region of Mars. This region shows many signs of past activity, from trough-like ditches and steep cliffs to smooth plains and tall domes formed by volcanism.

The European Space Agency (ESA) just released some new snapshots from its Mars Express orbiter that detail the dynamic terrain of the Red Planet's Acheron Fossae region.

One of the photos shows trough-like features called "grabens," which run about 500 miles (800 kilometers), or roughly the length of Germany. They were shaped from ancient volcanic activity that twisted the surface of Mars almost four billion years ago.
