<Arizona State University has been studying the moon, and they recently let everyone know that those projectiles are smacking into our friendly moon 100 times faster than originally thought.>
This is a gross misrepresentation of the ASU article. The surface turnover rate is 100x faster than thought. It's not the velocity of bodies that is 100x faster.
Just for radiation protection, lunar colonists will spend most of their time under at least six feet of rock.
