Opportunity's View of 'Viking' Crater, Sol 421

August 18, 2005
On the 421st martian day, or sol, of its time on Mars (March 31,2005), NASA's Mars Exploration Rover Opportunity drove to within about 10 meters (33 feet) of a small crater called "Viking." After completing the day's 71-meter (233-foot) drive across flatland of the Meridiani Planum region, the rover used its navigation camera to take images combined into this view of its new surroundings, including the crater. That day was the last of Opportunity's second extended mission. On April 1, both Opportunity and its twin, Spirit, began third extensions approved by NASA for up to 18 more months of exploring Mars. This view is presented in a cylindrical projection with geometric seam correction.
