Uploader comment: This image, taken with the Narrow Angle Camera (NAC), shows a simple crater within Rembrandt Basin. Running through the crater is a lobate scarp, formed as Mercury's large iron core cooled and contracted, generating compressive forces that pushed one section of the planet's crust over the top of another section.
