Aitken Central Peak, Seen Obliquely

Southern end of Aitken crater central peak complex. The upper left is about 1000 meters above the crater floor, which is just seen at lower right. Bright material (high albedo) may be a landslide of local soil, or a secondary impact...

Erosional trough on crater wall

Erosional trough (400 m long x 100-200 m wide) on the eastern inner wall of the farside crater Moore F. Morphologically it resembles a martian sapping feature, suggested to form due to erosion by water flowing out of the subsurface....

Ejecta from Copernicus

One of the geologic features that makes Copernicus crater special is its extensive, high-reflectance ejecta rays that extend across nearby mare and superpose (overlap) ejecta from other craters - Copernican ejecta extends more than 500...

Ejecta Blanket

The pattern of ejecta from a young crater is still preserved on the floor of Van de Graaff crater. The variations in albedo (bright and dark areas in the ejecta) indicate either different surface exposure times, grain sizes, or...

Immature Ejecta

This crater in the floor of Van de Graaff crater has a high reflectance ejecta blanket compared to the surrounding low reflectance material. The contrast in albedo is due to the crater excavating "fresh" or "immature" material from...
