This image shows the Mars Exploration Rover Spirit's hand, or the tip of the instrument deployment device, poised in front of the rock nicknamed Adirondack. In preparation for grinding into Adirondack, Spirit cleaned off a portion of the rock's surface with a stainless steel brush located on its rock abrasion tool, seen here at the top of its hand. The image was taken by the rover's panoramic camera.
