Seriously? Water?This water stuff is exactly the kind of thing that could tip the balance politically.
I don't think you've noticed the kinds of people we have running this country, but there's only one thing they could possibly find on the moon that would make it a landing even REMOTELY politically feasible: OIL, and gigantic quantities. Since every geologist in the solar system knows there aint any on the moon, nobody's in a hurry to go there in person.
It's not about Obama. It's not even about congress. Hell, it isn't even about NASA. It's about the fact that America's political machine is basically dominated by profiteering gluttons who will kill ANY program that might compromise their profit margins. Hell, there are probably some insurance lobbyists who would privatize the police department if they thought it would allow them to raise premium. The only reason the space shuttle program lasted as long as it did was because Tom DeLay wanted to keep a few thousand high-paying engineering jobs in his congressional district; the only reason Orion lost funding is because the districts that will get those jobs are now being represented by people who don't have the clout to arm-twist NASA into giving them a better deal.
In the golden age of I Can't Believe It's Not Bribery, NASA isn't going to get any funding unless they start hiring lobbyists. Otherwise, there's no chance of going to the moon OR to mars until someone out there--probably the Rutan-Branson connection and some other brainguys--get around to turning manned space flight into an actual thriving business that doesn't depend (exclusively) on government funding.
They don't even care about that much. There's a LOT of quid pro quo going on between American politicians and the lobbyists who--half the time--actually write the bills for them to sign into law. Strictly speaking, the only reason for the moon mission in the first place was because Lockheed wanted something new and shiny to charge NASA for.Politicians don't really care about science. They care about perception.
