Iani Chaos

Iani Chaos is a region of chaos terrain at the south end of the outflow channel Ares Vallis, of the Margaritifer Sinus quadrangle (MC-19) region of the planet Mars, centered at approximately ~342°E, 2°S.

The chaotic terrain is widely believed to have formed via the removal of subsurface water or ice, resulting in flooding at the surface, and the formation of Ares Vallis.

The aim of the Mars Science Laboratory is to search for signs of ancient life.

It is hoped that a later mission could then return samples from sites identified as probably containing remains of life.
