Dusty Adirondack
Dusty Adirondack

This close-up image taken by the microscopic imager onboard the Mars Exploration Rover Spirit shows a portion of the rock dubbed Adirondack before dust was wiped from its surface by a brush on the rover's rock abrasion tool. Spirit cleaned the rock before grinding into it to expose fresh rock underneath. The observed area is 3 centimeters (1.2 inches) across.

Spirit Self-motivates

The Mars Exploration Rover Spirit drove itself 1 meter (3 feet) out of 6.4 meters (21 feet) at Gusev Crater, Mars, on Feb. 8, 2004, the 36th sol of its mission. This image shows the tracks it created in the martian soil as it drove straight ahead, then to the left. The rover also drove over Adirondack (seen in image bottom center), the bright rock that was targeted by Spirit's rock abrasion tool, on its way to a rock target called White Boat. This was the first test of the rover's autonomous system, which will be used many times in the days to come.

Spirit's First Grinding of a Rock on Mars
Spirit's First Grinding of a Rock on Mars

The round, shallow depression in this image resulted from history's first grinding of a rock on Mars. The rock abrasion tool on NASA's Spirit rover ground off the surface of a patch 45.5 millimeters (1.8 inches) in diameter on a rock called Adirondack. The hole is 2.65 millimeters (0.1 inch) deep, exposing fresh interior material of the rock for close inspection with the rover's microscopic imager and two spectrometers on the robotic arm. This image was taken by Spirit's panoramic camera, providing a quick visual check of the success of the grinding. The rock abrasion tools on both Mars Exploration Rovers were supplied by Honeybee Robotics, New York, N.Y.
