March 11, 2004 — Spirit sent back this navigation camera image mosaic revealing so-called Bonneville Crater in its entirety. Spirit has spent more than 60 sols, two-thirds of the 90-day mission, en route to the rim of the large crater. The rover stopped on occasion to examine rocks along the way, many of which probably found their resting places after being ejected from the nearly 200-meter-diameter (656-foot) crater. The science team sent the rover to Bonneville to find out more about where the rocks they have examined so far originated. Reaching the rim of this deep dish has been a major priority since day one.
