NEAR
Shoemaker captured this picture of two similarly sized craters in
different states of preservation on January 1, 2001, from an orbital
altitude of 35 km.
The large "fresh" crater near the top of the frame exhibits
a bowl shape with a relatively well-defined, sharp rim. The "degraded"
one below it is puckered by smaller craters and probably partly
buried by regolith, so the crisp detail visible in the top crater
has been lost. The whole scene is about 0.9 km across.
