Our science goal is to determine the nature of ridges and troughs in crater ejecta
In this image footprint are various examples of modifications to the ejecta. Some parts seem to have formed blisters that broke open into ridges and troughs. But, some terrain next to it did not. HiRISE may be able to see variations in the surface materials that might account for their different behaviors, as well as examining the ridges.
