Quoted from "schmidt349":
"The fact that the Shuttle was still flying in 2011 isn’t just a testament to its longevity. It’s a sad reminder that, at least for now, human spaceflight is at the mercy of the schizophrenia that is the American political process.
NASA has consistently brought together some of the finest minds in the world to do what the preceding finest minds thought was impossible. Then, because this is America, we take a bunch of mouth-breathers who probably got Cs and Ds in basic high school science courses and make them the bosses and the gatekeepers, the people who decide that it’s more important to systematize the abuse of human rights at airports and buy the jokers at the Pentagon their newest murder toy than it is to push the frontiers of knowledge and ingenuity.
I’m putting my hope for the future of space exploration in private hands. Not because I fetishize the free market, or because I think government is evil, but because human spaceflight is way too important to be put in the hands of the American electorate, which is probably the stupidest and most poorly-informed decision-making body since the Athenian ekklesia."
