Amazing but true After 13 years and nearly 11 months of exposure to the forces of Mars, you can still make-out the legend, “Two Worlds One Sun,” emblazoned on Opportunity’s Sundial which is also the Panoramic Camera color calibration instrument. The brainchild of Planetary Society CEO Bill Nye, the sundials on Opportunity and Spirit are the first interplanetary sundials. Renowned astronomy artist Jon Lomberg helped design the sundials, which also feature the name ‘Mars’ in 16 present and past languages. NASA / JPL-Caltech
