Mars - Viking Orbiters 1 and 2

Global mosaic of the Syrtis Major Planus on Mars

Viking Orbiter mosaic of the Syrtis Major Planus region on Mars, showing a point perspective view from 2000 km. The mosaic is composed of about 100 red and violet filter images acquired in 1980 during martian early northern summer. The image is centered at -1 latitude, 306 longitude. The large light colored area at upper left is Arabia, the dark area to the right is Syrtis Major Planus. The dark color may be the result of basaltic lava flows. To the far right is the light-colored, smooth edge of Isidis Planitia. The large crater towards the bottom center of the image with black markings in its lower right is the 470-km diameter Huygens crater. The edge of the Hellas basin is at extreme south (down) on this frame. The dark feature at left is Sinus Sabeus. (Viking Orbiters 1 and 2, MG01S306-347SP)
