Mars Global Surveyor (MGS) view of Mars
Mars Global Surveyor (MGS) orbits around the red planet 12 times a day. Each orbit goes from pole to pole. Over the course of a single day, the wide angle cameras of the Mars Orbiter Camera (MOC) system take 24 pictures--12 red and 12 blue--that are assembled to create a daily global map. Such global views are used to monitor the Martian weather and observe changes in the patterns of frost and dust distribution on the surface. This picture is an example of what Mars looks like in late northern summer, which is also late southern winter. At this time of year, the south polar cap (bottom, white feature) is very large, extending from the south pole northward to 60°S. Also at this time of year, clouds of water ice crystals are common over the four largest volcanoes in Tharsis. The picture shows Tharsis, with the four volcanoes forming a triangle resembling the pattern of holes on a bowling ball.
