Wiggling Its Way to Discovery
This image shows the Mars Exploration Rover Spirit's view from its new location inside the shallow depression dubbed "Laguna Hollow." To get a better look at the soil making up the hollow, Spirit drove forward a bit, wiggled its wheels, then turned and backed up. The result - a scrape on the floor and a clod of dirt stuck on one of Spirit's wheels - told scientists that the soil is sticky and reminiscent of that observed at the airbag drag mark nicknamed "Magic Carpet." Spirit will further investigate this disturbed patch of soil with its robotic arm beginning today (Feb. 19, 2004). It will also dig a trench at "Laguna Hollow" with one of its wheels. This fish-eye image was taken by the rover's hazard-avoidance camera.
