This color image from the Curiosity rover, released by NASA on Monday, shows an area excavated by the blast of the Mars Science Laboratory rover’s descent-stage rocket engines. This is part of a larger, high-resolution color mosaic made from images obtained by Curiosity’s Mast Camera. With the loose debris blasted away by the rockets, details of the underlying materials are clearly seen. Of particular note is a well-defined, topmost layer that contains fragments of rock embedded in a matrix of finer material. The top two arrows in the inset indicate 1.25-inch pebbles and a larger, 4-inch-long clastic rock protruding about 2 inches from the layer in which it is embedded.
