On September 11, 2007, NASA's Mars Exploration Rover Opportunity entered Victoria Crater on the rover's 1,291st martian day, or sol. The rover team commanded Opportunity to drive just far enough into the crater to get all six wheels onto the inner slope, and then to back out again and assess how much the wheels slipped on the slope. The rover team will assess results of the drive, then start Opportunity on an extended exploration inside the crater. This wide-angle view taken by the rover's front hazard-identification camera shows the wheel tracks created by the short dip into the crater. The left half of the image looks across an alcove informally named "Duck Bay" toward a promontory called "Cape Verde" clockwise around the crater wall. The right half of the image looks across the main body of the crater.
