Lunar far side samples bolster theory that the moon was once covered in magma

A team of geologists at the Chinese Academy of Geological Sciences, the Institute of Space Sciences and the Shandong Institute of Geological Sciences, all in China, has found evidence in soil samples collected from the far side of the moon that bolsters a theory that the moon was once covered by an ocean of magma. In their study published in the journal Science, the group analyzed a moon soil sample returned to Earth by China's Chang'e-6 mission.
