What's up with that rock? China's moon rover finds something strange on the far side.

China's Yutu-2 lunar rover has discovered what appear to be relatively young rocks during its recent exploration activities on the lunar far side.

The report showed the crater region age was some 3.6E+9 years old and said this about the young rocks "Regarding the age of the rocks, Moriarty said that "fresh" is a relative term: In this case, it means that the rocks formed after the major resurfacing events in Von Kármán crater. "So that could be 10-100 million years [ago] or 1-2 billion years. It's really hard to say definitively."

This is quite an age spread here but not uncommon. Over the years, I track *young age* reports about the Moon. Here is an example. A facelift for the Moon every 81,000 years, another report shows some surface features 50E+6 years old or younger, Mars and Moon: Not Dead Yet?

Reconciling different age measurements is fun :) Apollo lunar rock radiometric ages, their cosmic ray exposure ages, crater dating extrapolations, etc. Reporting all those different age measurements and showing them together, that is still a work in progress I feel for many published in popular science sites.
