This computer-generated perspective view shows a crater in the Melas Dorsa region of Mars. The picture was created from data acquired by the European Space Agency's Mars Express orbiter, and released by the ESA on July 5. The 10-mile-wide crater's shape and the butterfly-shaped blanket of debris suggest that the landscape was altered by a comet or asteroid that made a low-angle impact.

A full-circle view from NASA's Opportunity rover, released on July 5, shows an area of Mars known as Greeley Haven. This is where the rover spent four months during the Martian winter. Among the sights visible in the panoramic image are the fresh tracks made by the rover as it studied the site. The rover's solar arrays and deck can be seen in the foreground.

This image from NASA's Mars Reconnaissance Orbiter, released July 18, shows a crater wall in the Red Planet's southern hemisphere with gully landforms. In the Martian winter, frost - mostly carbon dioxide - can build up in the gullies, especially on the cold slopes that face the pole. In this enhanced-color view, bluish frost can be clearly seen in the upper alcoves of the gullies.
