Mars Analogs On the Cover: Though Chile’s Atacama Desert is more thoroughly etched by past water than is the surface of Mars, it compares strikingly well with images from Mars at a variety of scales. This image of an intermountain drainage basin looks superficially similar to the walls and floor of Mars’ Valles Marineris.
