Far side of the Moon

The far side of the Moon is the hemisphere of the Moon that always faces away from Earth. The far side's terrain is rugged, with a multitude of impact craters and relatively few flat lunar maria. It has one of the largest craters in the Solar System, the South Pole–Aitken basin. Although both sides of the moon experience two weeks of sunlight followed by two weeks of night, the far side is also referred to as the dark side of the Moon, originally in the sense of "unknown" rather than lack of light.

About 18 percent of the far side is occasionally visible from Earth due to libration. The remaining 82 percent remained unobserved until 1959, when the Soviet Union's Luna 3 space probe photographed it. The Soviet Academy of Sciences published the first atlas of the far side in 1960. In 1968, the Apollo 8 mission's astronauts were the first humans to view this region directly when they orbited the Moon. To date, no human being has ever stood on the surface of the far side of the Moon.

Astronomers have suggested installing a large radio telescope on the far side, where the Moon would shield it from possible radio interference from Earth. Please note* although theory of the moon and clear signs that the molten lava from the core of the satellite on what we could only see calling it near side, and as soon as Apollo 16 took the first photographs for the first time we were able to see what in fact the dark/far side surface looked like,.It was completely different to that of the side positioned facing earth and showed that unlike our side which molten lava surged up and through the surfaces crust, causing huge craters and dark lakes of solid formed lava.. Why this is so, and reasons to take into account is different than stated on all research reports, it was not down to the dark / far side`s thickness of crust aprox 30 miles thicker, and thus no lava able to break through..it was more the facts of the moon controlled and over powered by the earth gravitational pull which would have caused and affected the near sides core be pulled when liquefied molten lava gravity .. failed to affect the far side as it was never facing earth thus gravity had no pulling power of bringing lava up to its surface
