New Mars images shows ‘fingernail’ gouging-like features on surface

Scratches and grooves on the Martian surface look like a huge ‘fingernail’ was gouging out regolith on the Red Planet, but there’s a volcanic origin to these features.

Specifically, scientists believe that these faults, dubbed Tantalus Fossae, were created by the volcano Alba Mons, which is located to the west of the terrain visible in the striking new views. The images are based on data gathered by the European Space Agency’s (ESA) Mars Express mission, which has been orbiting Mars since 2003.
