Nasa Mars rover makes detailed crater image

Scientists have remarked that the rover's surroundings resembled parts of the southwestern US.

Curiosity's ultimate goal is to drive towards a peak - informally known as Mount Sharp - to study its rocks.

Shown in the mosaic is a section on the crater wall where a network of valleys are believed to have formed through water entering from the outside.

This high-resolution picture is the first view scientists have had of a fluvial system - one relating to a river or stream - from the surface of Mars.

You can see the full-resolution version of the above panorama here.

This color image from NASA's Curiosity rover shows part of the wall of Gale Crater, the location on Mars where the rover landed on Aug. 5, 2012 PDT.

The Gale Crate wall north of the landing site shows a network of valleys that may be formed by erosion from water flowing into the Gale Crater. These fluvial systems are believed to be millions or even billions of years old -- from a time of Mars when water flowed freely across the surface. The main channel deposit seen here resembles a dirt road ascending into the mountains, which are actually the north wall and rim of Gale Crater.

Rockets from the descent stage of the rover's landing last week blew away fine dust on the surface, uncovering the bedrock below. Of particular note, NASA says, is a well-defined, topmost layer that contains fragments of rock embedded in a matrix of finer material, Seen here in the inset of the image are pebbles up to 1.25 inches across (the upper two arrows) and a larger clast 4 inches long protruding up by about 2 inches from the layer in which it is embedded. Clast-rich sedimentary layers can form in a number of ways. Their mechanisms of formation can be distinguished by the size, shape, surface textures, and positioning with respect to each other of the fragments in the layers.
