NASA's Mars Exploration Rover Opportunity recorded this stereo view of a crater informally named "Freedom 7" shortly before the 50th anniversary of the first American in space: astronaut Alan Shepard's flight in the Freedom 7 spacecraft.

The image combines four frames that Opportunity took with its navigation camera during the 2,585th Martian day, or sol, of the rover's work on Mars (May 2, 2011). Shepard's suborbital flight lasted 15 minutes on May 5, 1961. Two of the frames come from the camera's left eye, the other two from its right eye. The scene appears three dimensional when viewed through red-blue glasses with the red lens on the left.

The crater is about 25 meters (82 feet) in diameter. It is the largest of a cluster of about eight craters all formed just after an impactor broke apart in the Martian atmosphere.

By taking advantage of seeing many craters of diverse ages during drives between major destinations, the Opportunity mission is documenting how impact craters change with time. The cluster that includes Freedom 7 crater formed after sand ripples in the area last migrated, which is estimated to be about 200,000 years ago.
