The Far Side of the Moon Springer | 2007-12-06 | ISBN: 0387732055 | 220 pages | PDF | 21,1 MB The far side of the Moon, also called the "dark side of the Moon" was unknown to humanity until the Luna and Lunar Orbiter pictures were returned to Earth. Even since then, its nature has puzzled researchers. Now we know that a giant impact struck the near side with such force that it created the “near side megabasin”, opening the way for floods of mare and sending vast amounts of ejecta to the far side. The Far Side of the Moon explains this event and also documents the appearance of the features of the far side with beautiful pictures from Lunar Orbiter.
