Rabe Crater
About this image
Today's VIS image shows part of the floor of Rabe Crater. Located in Noachis Terra, Rabe Crater is 108 km (67 miles) across. Craters of similar size as Rabe Crater often have flat floors. Rabe Crater has some areas of flat floor, but also has a large complex pit occupying a substantial part of the floor. The interior fill of the crater is thought to be layered sediments created by wind and or water action. The pit is eroded into this material. The eroded materials appear to have stayed within the crater forming a large sand sheet with surface dune forms as well as individual dunes where the crater floor is visible. Several other craters in this region have complex floors with pits. This image shows part of the pit and some of the sand dunes within it.
