Hampton, Virginia -- The National Aeronautics and Space Administration's Lunar Orbiter IV spacecraft completed its photographic survey mission by returning telephoto pictures of 99 percent of the Moon's front face. The broad cross-hatched area on this chart indicates telephoto picture coverage from apolune photography. Arrows A and B at top show regions totaling one percent which were photographed in wide angle but not in telephoto pictures. As a result of the success of Lunar Orbiter IV scientists now have pictures of the visible face of the Moon with ten times more detail than the best existing telescope views.
