About this work

This 280-kilometer diameter crater center has experienced a long history of water activity. Within the crater is a heavily faulted and fractured terrain called Aram Chaos that consists of darker volcanic rocks that were disrupted as a result of water and/or magma withdrawal in the subsurface. Above this chaotic terrain are brighter materials made up of different kinds of sulfates that formed when water filled the crater.
