So moon crater ice sublimates slow enough to not disappear a-la Europa?

  That was my argument, before this article was published. The counter argument of course, is that it does sublimate (as water does from comets), but there's a vast amount (remains of a crashed comet, say); plus dust accumulating on the surface seals it fairly well over time. So I'm now guessing we're not talking "a few millimeters of water" as others have speculated, but really large amounts.
