Mozaic of Mars

Mozaic of Mars

. This computer-generated mosaic of Viking orbiter images of Mars shows three volcanoes as dark spots to the west (left), while the bottom center of the scene shows the entire Valles Marineris canyon system, from Noctis Labyrinthus (left) to the chaotic terrain (right). Outflow channels are found in the north (top), and a variety of clouds and hazes are also visible, especially near the edge. (Courtesy of Alfred S. McEwen, U.S. Geological Survey.)
