Hemet, not only is most of it spent here, ALL of it is spent here, and most of THAT is spent in America. Quite a bit of the money that NASA spends goes to local businesses in the area not only because of their employees (someone commented on how they doubt NASA scientists don't spend their money at wal-mart, I can tell you for a fact that's wrong. They do.) but as a whole if they need parts for something, they get it locally. If they need some special part invented for something, they go to a business that specializes in that and when it's finished, works out a deal with the licensing of the patent, which means NASA gets a tiny bit of that money back to put towards more inventions, and we get to see those things made for sale to the public. (it would be perfectly within their rights to keep all the rights to these things and we'd never see them except for use by NASA.)
