Opportunity's Surroundings After Backwards Drive, Sol 1850 (Stereo)
NASA's Mars Exploration Rover Opportunity used its navigation camera to take the images combined into this stereo, 360-degree view of the rover's surroundings on the 1,850th Martian day, or sol, of its surface mission (April 7, 2009). The view appears three-dimensional when viewed through red-blue glasses with the red lens on the left.
Opportunity had driven 62.5 meters (205 feet) that sol, southward away from an outcrop called "Penrhyn," which the rover had been examining for a few sols, and toward a crater called "Adventure." In preceding drives, the drive motor for the right-front wheel had been drawing more current than usual, so engineers drove Opportunity backward on Sol 1950, a strategy to redistribute lubricant and reduce friction in the wheel.
North is in the center of the image; south at both ends. Opportunity's position on Sol 1850 was about 1.3 kilometers (0.8 mile) south-southwest of Victoria Crater. For scale, the distance between the parallel wheel tracks is about 1 meter (about 40 inches).
This panorama combines right-eye and left-eye views presented as cylindrical-perspective projections with geometric seam correction.
