Discovery by lunar probe may explain how moon was formed

China's Yutu 2, the first rover on the far side of the moon, has found matter from the mantle that could help explain how the moon and Earth formed.

The Chang'e 4 probe landed in the Von Karman Crater in the moon's South Pole-Aitken basin on Jan 3 and the Yutu 2 rover began its investigations using a visible and near-infrared spectrometer to analyze the light reflected from the crater's surface.

The most important scientific discovery of the probe to date was published online in the latest issue of the academic journal Nature.
