Opportunity snaps Meridiani on Mars

Researchers published the first set of reports on the second Mars rover, Opportunity, in Science on Dec. 3. Below are some images from the rover's Pancam.

Opportunity found some of the first evidence of water on Mars in "blueberries," tiny hematite concretions that may have been deposited in shallow-water environments. This close-up image of the blueberries blanketing the ripples and troughs in the Meridiani Planum is an enhanced natural-color Pancam photograph. On Opportunity's 70th martian day, it snapped a Navcam self-portrait. Opportunity's tracks, each 16 centimeters wide, disrupted wind-blown ripples on the Meridiani plains.
