Martian landscape, true_colour panorama, obtained by the Opportunity Mars Exploration Rover MER_B. This is the Payson outcrop on the western edge of the Erebus crater. The crater wall orange is about one metre thick, and was formed by the impact event that formed the crater. Opportunity landed in the Meridiani Planum region of Mars in January 2004. The colours of the image were created by combining camera filters to approximate what a human would see. This 90_degree panorama was obtained on 26 February 2006, on the 744th Martian day of the rover磗 mission.
