Solar storms could sandblast the moon
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. 😉
