This image from the Mars Exploration
Rover Spirit's rear hazard identification camera shows the rover's
hind view of the lander platform, on which it was sitting for
the past 12 sols, or martian days. The rover is approximately
1 meter (3 feet) in front of the airbag-cushioned lander, facing
northwest. Note the tracks left in the martian soil by the rover's
six wheels. This is the first time the rover has touched martian
soil.
