On September 9, the eve of the Chinese traditional Mid Autumn Festival, the National Space Administration and the National Atomic Energy Agency jointly released the latest scientific achievements of Chang'e V in Beijing. Dong Baotong, deputy director of the National Atomic Energy Agency, announced at the launch that the new mineral first discovered by Chinese scientists on the moon was named "Chang'e stone". This mineral is the sixth new mineral discovered by human beings on the moon, and China has become the third country in the world to discover new minerals on the moon. Chang'e stone is a phosphate mineral with columnar crystals, which exists in lunar basalt particles. Through a series of high-tech means such as X-ray diffraction, the innovation team of Beijing Geological Research Institute of nuclear industry of CNNC separated a single crystal particle with a diameter of about 10 microns from 140000 lunar sample particles and successfully interpreted its crystal structure. It was approved by the new mineral classification and Nomenclature Committee (cnmnc) of the International Mineral Society (IMA) and confirmed to be a new mineral.
