An Old Crater Almost Completely Filled with Regolith

An Old Crater Almost Completely Filled with Regolith

This image of asteroid Vesta from NASA's Dawn spacecraft shows an old, very degraded crater that is almost completely filled with regolith. Regolith is the fine-grained material that covers most of Vesta's surface.
