Moon surface photo taken with Lunar Orbiter IV
An enormous and complex lunar feature never before viewed from above was photographed by wide-angle lens as NASA's Lunar Orbiter IV spacecraft neared the end of its survey mission of the Moon. It is Orientale Basin, centered at 90 degrees West longitude and 15 degrees South latitude on the extreme western edge of the Moon's visible side. Its circular outer scarp, the Cordillera Mountains, is just over 600 miles in diameter. In this photograph, the Orientale Basin is at the center.
