Explanation: Stark shadows show off the central peaks and terraced walls of 120 kilometer wide Pythagoras Crater in this mosaic of images from ESA's SMART-1 spacecraft. Characteristic of large, complex impact craters on the Moon, the central uplift was
produced by a rebound of the suddenly molten lunar crust during the violent impact event. Propelled by an efficient ion engine, the innovative SMART-1 spacecraft entered lunar orbit in No
