Petavian View

Sunrise on Petavius provides wonderful views of a large complex crater, but also the surrounding areas are fascinating too. The most conspicuous background feature is the large crater Humboldt with a bright interior with dark mare on its edges and just barely visible radial fractures. Near the right edge of the image are three linear structures of interest. A bent rille that casts shadows cuts the floor of Furnerius, and the linear Hase Rille extends to the upper right. The broader and less well-defined Snellius Valley is like a series of oblong craters trending up and to the right above Petavius. Petavius itself exhibits many instructive features. Radiating away are ridges of ejecta that give way to secondaries showing up as dark pits at this illumination. The floor contains hills and rubble that seem to be coated with smooth material. Craters of Petavius' size often show the beginning of a transition to a peak ring surrounding the central mountain, and you can see it here.
