Dunes Cascade Into Martian Crater

Dunes Cascade Into Martian Crater

Rabe Crater perspective node full image.jpg

The Mars Express has produced this dynamic image of the martian surface. The dark dunes are made from the basaltic volcanic rock. You can see in the picture the prevailing winds have swept the dunes across the steep walled crater, known as Rabe crater that is 108km wide. The dark material has then collapsed into the crater creating this fascinating image of what looks like a black waterfall. This is another image that demonstrates nicely that the surface of Mars is not an unchanging dead place but very dynamic and certainly has a lot more to be discovered.
