Spirit's Trip to the Hills
This overhead view of a portion of Gusev Crater shows the route the Mars Exploration Rover Spirit has traveled since arriving on the red planet over five months ago. On sol 156 (June 11, 2004), Spirit reached the base of the "Columbia Hills," where it is currently investigating some unusual rocks. The rover may eventually head to the top of one of the closest hills.
This image is a composite of images taken by the camera on the orbiting Mars Global Surveyor and the descent image motion estimation system camera located on the bottom of the rover's lander.
