The moon's far side has a thick, old crust and is pockmarked by many deep craters.

SHANGHAI, CHINA—China's ambitious program of lunar exploration is about to attempt a spacefaring first: On 8 December it will launch a probe intended to land on the far side of the moon. Besides boasting rights, the Chang'e-4 lander and rover are expected to produce a host of new insights into the moon's composition and history. "Chang'e-4 is an historical mission," says Bernard Foing, director of the European Space Agency's (ESA's) International Lunar Exploration Working Group in Noordwijk, the Netherlands.
