Guest: Daniel Moriarty, PhD, Postdoc researcher in planetary geology, NASA Shortly after the moon formed, something gigantic smacked into it, leaving a mark large enough to fit half of the continental United States. This crater takes up a quarter of the Moon’s surface. And scientists think it holds the keys to understanding the early days of the solar system.  They’re looking for the best landing site in the giant crater to collect Moon rocks that would reveal those secrets.
