Mars Global Mosaic, from the Viking Mission

Mars_globe-viking-m-1200x1200

This global view of Mars was created from Viking Mission data. The vast canyon of Valles Marineris is prominent as an east-west scar just below center. The giant sheild volcanoes of the Tharsis region are on the left side, with the massive Olympus Mons near the edge (just north of west in this view). For the full-resolution version and detailed information, visit NASA JPL's Planetary Photojournal:
