Chinese scientists rewrite lunar impact history with Chang'e 6 moon soil

Chinese scientists used samples brought back by Chang’e 6 from the far side of the Moon, combined with lunar remote sensing images, to revise the lunar impact crater dating model that has been used for decades. The study found that the meteoric impact flux on both the near and far sides of the Moon is basically consistent, with early impact flux showing a smooth decline, which does not support the “late heavy bombardment” hypothesis. The samples brought back by Chang’e 6 include approximately 2.807 billion-year-old young basalt and 4.25 billion-year-old ancient Suchang rock, laying the foundation for establishing a global impact crater dating model. The new model refutes two major controversial hypotheses and reveals that early lunar impact activity was a process of smooth decline. (CCTV News)
