Insurance Vampire: you sell mattresses as well? Is there nothing the grasping multi-national conglomerate of Indycorp doesn't have a market share in?
I wouldn't object to going to the Moon if there was a direct and immediate benefit, something useful to bring back. But, afaik, the only thing of any use on the Moon is supposed to be water? and let's face it, there's plenty of that down here already, and in a few decades we'll have a lot more (especially if you live in low lying coastal districts) Ah well, I dare say the Moon people will be glad if no-one turns up.
more seriously: CV has a good point re: why the Moon programme rears its head every few years. It's a matter of national pride for the US, I think, having been the only people to get there, and not having been back since the early 70s, so when the US is hard pressed and feeling insecure, someone says "hey I know, why don't we go back to the Moon, then everyone will feel great!" There's no real practical reason to do it, but it gets headlines and let's folk forget for a while just how bad things are. You can see the same psychology at work in Russia - the country is a complete toilet and it's long since gone to the dogs (and the Mafia) but they keep plugging away with their space programme, and most Russians take a rather inappropriate degree of pride in it (still) as it's about all they've got that keeps them in the big leagues of world technology.
there's also a strategic issue; the US is the only country that could realistically get to the Moon and set up a permanent base, relatively quickly. Such a prospect would give it a superb strategic advantage for the rest of the century, missiles could be stuck up there very easily. Bearing in mind that only recently the US warned China off as regards competition for strategic advantage in space, a declaration of intent to go back to the Moon permanently makes more sense.
I believe that there is or at least was an international treaty against use of the Moon for military purposes, but we know how much international treaties are worth these days, don't we?
