Cataclysmic Conundrum - MyMoon

NASA and MyMoon have teamed up to blog about everything lunar. Art, literature, music, movies, science, and everything in between!

All quiet on the twitter front.


The latest blog from The Institute's Dr. Paul Spudis: Cataclysmic Conundrum.

One of the hottest topics in planetary science is the nature of the Moon’s early impact history. So it was not unexpected that the Early Impact Bombardment of the Solar System workshop, recently held at the Lunar and Planetary Institute in Houston, generated some interesting discussion. More than 30 years ago, when researchers at Caltech and elsewhere noted that many lunar highland impact generated rocks had very similar ages, they advanced the idea that the early Moon underwent an extremely large increase (peak) in the rate of asteroid and comet bombardment 3.9 billion years ago (600 million years after the Moon had formed). They called this late bombardment the lunar “cataclysm.” Read more.
