Grand Canyon-size 'scar' on Mars revealed in striking new satellite photos

New satellite photos from the European Space Agency's Mars Express orbiter have revealed a Grand Canyon-sized "scar" on Mars known as Aganippe Fossa. This massive ravine, around 375 miles long, was likely formed by volcanic activity millions of years ago. The images show zebra-like stripes accompanying the dark ravine, indicating unique geological features. The graben, a ditch-like groove with steep walls, is considered a single structure despite breaks along its length. The surrounding landscape varies significantly, with one side showing mounds, grooves, and ridges, while the other side displays smooth terrain with rocky stripes. Aganippe Fossa is located near the base of the extinct volcano Arsia Mons and is believed to have been caused by magma activity beneath the surface. The region around Tharsis on Mars is geologically intriguing, with other notable features like Noctis Labyrinthus and evidence of recent volcanic activity. These findings shed light on the complex geological history of the Red Planet.
