Left-eye view of a color stereo pair for PIA12137

Right-eye view of a color stereo pair for PIA12137

This stereo scene combines frames taken by the navigation camera on NASA's Mars Exploration Rover Spirit during the 1,866th Martian day, or sol, of Spirit's mission on Mars (April 3, 2009). It spans 120 degrees, with south at the center. The view appears three-dimensional when viewed through red-blue glasses with the red lens on the left.

Spirit had driven 3 meters (10 feet) southward earlier in the day. The foreground of this view includes terrain that the rover covered in its next drive, when it progressed 17.5 meters (57 feet) farther southward on Sol 1868 (April 5, 2009).

In the middle distance, the western edge of the low plateau called "Home Plate" is on the left and a ridge called "Tsiolkovsky" is on the right, with the rover's planned route between the two. By Sol 1899 (May 6, 2009) Spirit became embedded at a site dubbed "Troy," about as far south as the northern end of Tsiolkovsky.

This scene combines right-eye and left-eye views presented as cylindrical-perspective projections with geometric seam correction.
