Not only does it have the tallest known volcano in the Solar System, but it also has the deepest canyon — plunging miles further than any cavern on Earth.
This week, the European Space Agency released new images of one of the deepest regions on the planet from its Mars Express orbiter.
Mars Express has been circling the red planet since 2003.
The gigantic region is almost 10 times longer and five times deeper than the Grand Canyon on Earth.

It’s also a spot that researchers think may have once been filled with flowing water.
And recent observations show it could potentially have ice frozen below the ground today.
Here are four new views of the red planet’s depths:
4. From the sky, the Ius (top) and Tithonium Chasmata are seen carved into Mars’ surface.
2. The section of the Tithonium Chasma recently surveyed reaches depths of over 2000 meters (1.2 miles), though there are other regions that reach up to 7 miles deep.
