This image shows the Mars Exploration Rover Opportunity at the end of its sol 95 drive to the edge of "Endurance Crater." The rover stopped within 40 centimeters (15.7 inches) of the crater's edge on its first approach, seen in this image. The terrain model in this image was generated with a special software program called the Rover Sequencing and Visualization Program. The program is used by rover drivers to simulate and safely plan the rover's approach path. Blank areas in the image denote missing data.
