Mars Double Duty
This image shows Spirit in its new location at a circular depression dubbed "Laguna Hollow." Scientists are interested in the abundance of very fine, dust-like soil here. To get a better look at the variations in the fine-grained dust at different depths, controllers commanded Spirit to "jiggle" its wheels in the soil before backing away to a distance that allows the area to be reached with the robotic arm.
