By my lights, Ray Bradbury isn't making much sense. In one paragraph he wants President Obama to announce that we (which, in context, can only mean We the Government) should be going to the Moon and Mars, etc., and in the next paragraph he says, "There is too much government today." Choose one, Mr Bradbury.
Perhaps Mr Obama's only true success since January 2009 is his evisceration of NASA's manned space program, which is one of the first few necessary steps toward opening space to ordinary people eager to do great things and make a buck while doing them. It's fine to have NASA working on propulsion systems and deep solar system exploration; meanwhile, get NASA out of Earth orbit and let us get up there ourselves.
