Martian mysteries




        Science is constantly probing the many unknowns of
        Mars—the presence of liquid water, the question of ongoing
        volcanism, and whether there was or is life on the planet.
        Some centuries-old mysteries and myths have been
        answered. There is no intelligent life as we know it, no
        canals, no seas, no vegetation. Yet some images sent back by
        satellites have shown puzzling objects on Mars: clusters of
        pyramids, a sculptured dolphin, an ancient Egyptian queen,
        and a head with a crown. A few writers insisted these images
        showed artificial structures made by aliens long ago.
        Improved high-resolution cameras, however, have revealed
        that they are natural geological formations. It is the play of               THE “FACE ON MARS”
                                                                                     There is an image among the buttes, knobs,
        light and shadows on these formations that makes them                        and mesas near western Arabia Terra that is
        appear like faces, animal forms, and man-made structures.                    like a human face. Photographed by Viking 1

                                                                                     became the subject of talk shows, books,
                                                                                     tabloids, and a movie. Then Mars Global
