This image mosaic of the "Columbia Hills" is the first 360-degree panorama taken since the Mars Exploration Rover Spirit arrived at the hills over a month ago.The dark patch of soil to the right is the spot where Spirit stopped for engineering work on its right front wheel. Spirit's tracks can be followed from there all the way back to "Bonneville Crater" and the original landing site, more than 3 kilometers (1.86 miles) away. The rim of Gusev Crater can be seen in the distance at center. Credit: NASA/JPL. Click to enlarge.
