    A view of the Moon never seen before the Space Age, and not visible from the Earth. This picture of the backside of the Moon was recorded by cameras aboard Apollo 16 in April 1972. The image is centered on the boundary between the lunar near side (upper left) and the Moon's hidden face (lower right). Three lunar maria are visible as dark patches on the near side. Clockwise from upper left: the Sea of Crises, the Border Sea and Smyth's sea. At lower right are the light-colored and heavily cratered highlands of the far side of the Moon. They contain almost none of the dark maria that characterize the side of the Moon that faces the Earth. (Courtesy of NASA.)
