Spirit's
Robotic Arm Prepares to Grind the Rock 'Adirondack'
This image shows the tip of Mars
Exploration Rover Spirit's instrument deployment device poised
in front of the rock nicknamed Adirondack. Before being able to
grind, Spirit cleaned off a portion of the rock's surface with
a stainless steel brush located on its rock abrasion tool (called
a "RAT"), seen here at the top of its hand. The image
was taken by the rover's panoramic camera.
