Click on the image for Spirit Tracks on Mars, Sol 151 (QTVR)

This cylindrical projection mosaic was created from navigation camera images acquired by NASA's Mars Exploration Rover Spirit during Spirit's 151st martian day, or sol, on June 5, 2004. The rover sits at site 63, still more than 100 meters (328 feet) from the base of the "Columbia Hills." As suggested by the rover tracks fading off in the distance, Spirit made great progress on this sol, roving 73 meters (240 feet) to get to this point.
