Artist's concept of possible exploration programs. This artist's concept is called 20/20 Vision. Did life ever exist on Mars? If so, the best evidence may be fossils preserved in the rocks. Geologists and biologists will one day explore Mars, piecing together the history of the planet and perhaps its ancient life. Artwork done for NASA by Pat Rawlings, of SAIC. (NASA Media Archives).
