Perspective view of the fracture system in Utopia Planitia

Perspective view of the fracture system in Utopia Planitia
This perspective angle view was calculated by the stereo channels of the High Resolution Stereo Camera operated by the German Aerospace Center on board the European Mars Express spacecraft.
 
A network of huge fractures covers the buried impact basin of Utopia Planitia. It measures 2000 kilometres in diameter and is located in the Martian Northern Lowlands. These surface structures, referred to as polygons, would suggest that an ocean once existed here.
