Rayed Crater in the Tharsis Region
Rayed Crater in the Tharsis Region
PSP_008011_1975  Science Theme: Impact Processes
This image shows a small rayed impact crater, about 160 meters in diameter, in the Tharsis region in the Northern Hemisphere of Mars.

Relatively recent impacts form rays of ejecta that spray out radially from the crater. In addition to relatively fine material, large boulders and smaller secondary craters are visible in the rays surrounding this crater.

Secondary craters are recognized by their shallow depths (in comparison to primary craters), irregular shapes, and appearance in clusters and linear chains.
