Chinese scientists declare discovery of new moon mineral from lunar rock samples brought back in 2020

  • Phosphate mineral Changesite-(Y) was isolated using a series of processes, including X-ray diffraction, according to China National Nuclear Corporation
  • CNNC party official says team measured concentration of Helium-3, a future fusion energy source, in lunar sample for future assessment and exploration

Chinese scientists have discovered a new mineral on the moon, making China the third nation after the United States and Russia to have discovered a lunar mineral, officials reported on Friday.

The mineral, called Changesite-(Y), was found in rock and dust samples retrieved from the moon by China’s Chang’e-5 mission, the nation’s first mission to return a lunar sample, which launched in 2020.

A research team from the Beijing Research Institute of Uranium Geology, a subsidiary of the China National Nuclear Corporation (CNNC), isolated a single crystalline particle of the material from more than 140,000 lunar particles using hi-tech processes, including X-ray diffraction, according to Wang Xuejun, a party official with the CNNC.

The particle was about 10 microns in diameter, or about one-tenth of a human hair, Wang told a press conference on Friday.

Changesite-(Y) is a phosphate mineral found in lunar basalts and the Commission on New Minerals, Nomenclature and Classification of the International Mineralogical Association has confirmed it as a new mineral, according to information presented at the conference.

It is the sixth new mineral discovered on the moon by humans.

“[The discovery] provides more basic scientific data for the evaluation and development of lunar resources and has deepened mankind’s knowledge of the moon and the solar system,” Dong Baotong, vice-chairman of the China Atomic Energy Authority, told the conference.

“China has also become the third country to retrieve lunar samples and discover new lunar minerals after the US and Russia,” he said.
