NASA have revealed stunning new panoramic imagery of Mars, taken by the Pancam on the Mars Exploration Rover Opportunity over a period of five months. The detailed photograph is compiled from 817 different images and captures everything from the Rover’s tracks to a 14-mile wide crater created billions of years ago and which, according to scientists, could hold evidence of ancient water. The release of this impressive image coincides with two milestones – Opportunity completing its 3,000th Martian day and NASA continuing past 15 years of robotic presence at Mars (Mars Pathfinder landed July 4, 1997). The above photos are taken from the original panoramic image.  (via HUH)
