They aren't shutting down NASA, as people have stated.
The shuttle program was intended to be a cheaper alternative to rockets that were one-time use one. This isn't what happened. Shuttle maintenance was so costly that they lost money on it, so they're finally ending the program to go back to rockets. I haven't heard anything new since the Ares rockets about a year ago, but that's about it.
They are cutting funding to NASA though. A lot, from what I hear. Seeing as how I live in an area with a LOT of NASA and aerospace jobs, I don't like that. If our government should be spending money, it should be on things like that. Exploration, new technology, science, and so on. But no, the military needs the money for more and more wars. The poor need it for healthcare. China needs it for debt payoff. Nobody cares about moving forward anymore. Everyone's focused on the past, or the current times at most.
