This picture of a heart-shaped pit was taken on 26 February 2008 by the CTX camera aboard MRO. It is approximately 2 km long. The pit is one of many adjacent to Hydaspis Chaos, a jumbled topographic depression thought to have formed by collapse of the surface due to-perhaps-catastrophic release of groundwater.
