Photo Mosaic of Schiaparelli Hemisphere, Mars, from Viking Orbiter
This mosaic is composed of about 100 Viking Orbiter images. The center of the image is near the impact crater Schiaparelli. The large circular area with a bright yellow color is known as Arabia. The dark streaks with bright margins emanating from craters in the Oxia Palus region are caused by erosion and/or deposition by the wind. Bright white areas to the south, including the Hellas impact basin at the lower right, are covered by carbon dioxide frost. --- Image by © NASA - digital version copyright/Science Faction/Corbis
