In this image from NASA's Curiosity rover, a rock outcrop called Link pops out from a Martian surface that is elsewhere blanketed by reddish-brown dust. The fractured Link outcrop has blocks of exposed, clean surfaces. Rounded gravel fragments, or clasts, up to a couple inches (few centimetres) in size are in a matrix of white material. Many gravel-sized rocks have eroded out of the outcrop onto the surface. The outcrop characteristics are consistent with a sedimentary conglomerate, or a rock that was formed by the deposition of water and is composed of many smaller rounded rocks cemented together. Water transport is the only process capable of producing the rounded shape of clasts of this size. The photo was enhanced by scientist to show the Martian scene as it would appear under the lighting conditions we have on Earth. Captured by a100-millimeter Mast Camera on Sept.
