This image shows a simulated view of Mars from orbit, looking at the planet from the north. White patches streaming from Olympus Mons and other Martian volcanoes are clouds of water ice.White patches at the top of the globe are north polar ice deposits. Hazy, brown streaks that obscure the surface are regional dust storms. The planet's surface appears gray-blue and tan.
