For decades, human knowledge of lunar geology came almost entirely from Apollo samples collected on the Moon’s near side. But new scientific analysis of soil and rock returned by China’s historic Chang’e-6 mission—the first-ever samples collected from the mysterious far side—is providing an unprecedented look into early solar system history!
Retrieved from the immense South Pole-Aitken Basin, these pristine rock fragments span an astounding 3.2-billion-year timeline (from 4.33 billion to 1.13 billion years ago).
Surprisingly, isotopic dating shows that asteroid impacts on the far side declined gradually over billions of years, rather than surging during a brief, catastrophic “Late Heavy Bombardment” as previously assumed!
Furthermore, these samples reveal crucial records of ancient lunar volcanism and show how Earth’s own magnetic field shield shaped solar wind bombardment on the Moon over eons. By unlocking the far side’s untouched vault, scientists are fundamentally rewriting how planetary crusts evolve!
Since the Moon’s far side turns out to have such a wildly different geological story than the side we see from Earth, what hidden secret do you think we’ll uncover next as we explore deeper into space? Drop your thoughts below and follow us for more!
