NASA's Mars Exploration Spirit examined a rock dubbed "Uchben" in the "Columbia Hills" inside Gusev Crater. Spirit took this image with its panoramic camera as it approached the rock during the rover's 278th martian day (Oct. 14, 2004). The visible portion of Uchben is about 50 centimenters (20 inches) long.

Abrasion Work on 'Uchben' (Figure 1)
Researchers used the rover Spirit's rock abrasion tool to help them study a rock dubbed "Uchben" in the "Columbia Hills" of Mars. The tool ground into the rock, creating a shallow hole 4.5 centimeters (1.8 inches) in diameter in the central upper portion of this image. It also used wire bristles to brush a portion of the surface below and to the right of the hole. Spirit used its panoramic camera during the rover's 293rd martian day (Oct. 29, 2004) to take the frames combined into this approximately true-color image.
