First ever look at the far side of the Moon. The photo was taken by the Soviet spacecraft Luna 3 on Oct. 7, 1959. The right three-quarters of the disk is the far side. A = Mare Moscoviense, B = Tsiolkovsky Crater with central peak, C = Mare Smythii (on the near side-far side border) and D = Mare Crisium (near side).

The thickness of the moon’s crust as calculated by NASA’s GRAIL mission. The near side is on the left-hand side of the picture, and the far side on the right. The near side has a thinner crust and bigger craters than the far side. (Credit: NASA/JPL-Caltech/S.
