NASA Detects Meteoric Rise In Lunar Meteors

netbuzz writes "Just because your software model can accurately predict the number of meteors that will hit the Earth doesn't mean it will fly on the surface of the moon. NASA scientists say little rocks are hitting that big rock at four times the rate they had anticipated when they started watching a year ago."

    It honestly probably doesn't make that much of a difference. The article says they've seen 11 or 12 impacts, I guess compared to the three or four that they were expecting. Spread 12 impacts across the visible surface of the moon, and you're going to end up with a very small percentage of the surface area that was visibly impacted. If the chances of getting hit were very small, 4 times a very small number is still a small number.

    I'd imagine that a more dangerous threat is radiation, and that whatever system was developed to shield against that would provide some level of protection against tiny meteor impacts. Once you start talking about bigger rocks, you quickly end up talking about amounts of kinetic energy that really aren't feasible to defend against in any manner approaching near cost-efficiency, and so you just sort of have to play the odds, realizing that the moon is not a particularly inviting or comfortable place.

Whether diamond is sensible or not I dunno: its ability to be cleaved by jewelers is perhaps less relevant than how it behaves under hypersonic shock (probably not particularly well, since the C-C bond network is very rigid), and when a small area of it is vaporized (probably better than average, since it conducts heat energy away rapidly, and because the disruption of each C-C bond will absorb a lot of energy).
