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 during Spirit's 34th sol on Mars, Feb.
6, 2004. 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.
