But if the moon isn't affected, then chances are, Mars won't be either. So then we might as well settle on Mars which is much less hostile. (much more water, an actual atmosphere, ect.) Like I believe was stated earlier, the Moon won't do us alot of good except for scientific purposes. Realistically, a Mars base won't be much further behind a moon base if we do construct one first. (Considering the quickening pace of technology, I don't see it coming any later than fifty years after the moon base, and likely less than twenty five) And if humanity gets wiped out in those twenty five years, then we will have serious problems.
