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, the rover's first science target since developing communication problems over two weeks ago. 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 and seen here at the end of the yellow arrow. The image was taken by the rover's panoramic camera.
