A Colorful 'Bounce'
This false-color composite of the rock dubbed "Bounce" shows the rock after the Mars Exploration Rover Opportunity drilled into it with its rock abrasion tool, or RAT.
The drilling of the 7-millimeter-deep (0.3-inch) hole generated a bright powder. The color in this image has been enhanced to show that these tailings are relatively blue when compared with the unaltered rock (to the human eye, the tailings would appear red).
