Tooting Crater


FRESHNESS AND CLARITY. Tooting Crater, named for a suburb of London, offers scientists a clear look at a fresh medium-size impact. This view, which looks toward the northwest, shows in the foreground the rampart that piled up about 80 meters (260 feet) high when the debris flowing from the impact came to rest. Here the rampart lies about 40 kilometers (25 miles) from the rim.

Craters in Arabia Terra


CRATERS AND DEPRESSIONS open "windows" into the subsurface terrain of northwest Arabia Terra. In the bottoms of some depressions lie deposits that formed under different environmental conditions than Mars has at present. This view (which has no vertical exaggeration) looks toward the north-northeast.
