Far side of the Moon. The dark crater towards lower right is Crater Tsiolkovsky, which was only half filled with lava after impact. The Moon's orbit of Earth is locked so that only one hemisphere faces Earth at all times. The far side was seen for the first time when Russian probes photographed it in the late 1950s, and many of the named features on that side are named after Russians.
