Moon exploration

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.

This is a portion of the Lunar Orbiter IV telephoto frame 172 taken by the spacecraft on its 31st orbit during its broad photographic survey of the Moon. When this frame was exposed, the spacecraft was traveling in a northerly direction which is towards the top of the picture when the edge data are positioned on the left. The spacecraft altitude was 1,870 miles above the lunar surface. The approximate selenographic coordinates for the center of the area shown are 68 degrees West, 43 degrees South.

Moon surface photo taken with Lunar Orbiter IV

An area of lunar surface displaying evidence of a very complicated geological history is seen in this portion of a Lunar Orbiter IV telephone picture made near the western edge of the Moon's visible surface. The large crater at right center is Riccioli, about 100 miles in diameter. Much of the area is covered by a blanket of debris deposited when the Mare Orientale, many miles further west, was formed by the impact of a giant meteorite.
