This animation is built from images taken by the navigation camera on NASA's Mars Exploration Rover Spirit from the rover's 365th martian day, or sol (Jan. 11, 2005), through sol 390 (Feb. 6, 2005). During this period, Spirit covered about 80 meters (262 feet) in its climb toward "Cumberland Ridge" in the "Columbia Hills." The sequence includes images from all of the sols on which Spirit drove during this period: sols 365, 366, 371, 381, 382, 386, 388 and 390.
