China moon mission samples upend theories of lunar volcanism


An analysis of lunar samples returned by China’s Chang’e 5 moon mission has produced a new possible answer for volcanism late in the moon’s history.

Lunar samples returned by the Apollo and Luna missions are all older than about 3 billion years, but samples returned by Chang’e 5 in late 2020 confirmed remote sensing analysis that rocks in the area were relatively young, at only 2 billion years old.
