ScienceDaily is reporting an interesting finding by the folks at Goddard Space Flight Center.

“We found that when this massive cloud of plasma strikes the moon, it acts like a sandblaster and easily removes volatile material from the surface,” said William Farrell, DREAM team lead at NASA Goddard. “The model predicts 100 to 200 tons of lunar material — the equivalent of 10 dump truck loads — could be stripped off the lunar surface during the typical 2-day passage of a CME.”

Luckily we’re protected by a strong magnetic field and we don’t have to worry about cosmic erosion very much on Earth. At least for the new few thousand years at least. 😉
