Satellite View of Opportunity Journey around Victoria Crater

Three years after embarking on a historic exploration of the red planet and six miles away from its landing site, NASA's Mars Exploration Rover Opportunity is traversing "Victoria Crater" ridge by ridge, peering at layered cliffs in the interior. To identify various alcoves and cliffs along the way, science team members are using names of places visited by the 16th-century Earth explorer Ferdinand Magellan and his crew aboard the ship Victoria, who proved the Earth is round.
