Here's how to get the funding NASA needs: Give them exactly half of what people think they already get. You can even ask them if that is a good amount: "How much of the budget does NASA get?" "I dunno, 40%?" "Do they do enough with that money?" "Heck no!" "How about we cut that in half and only give them 20%?" "Sounds about right..."
Kidding aside, there's a whole lot of ego going on here. America/NASA didn't lose it's way, and NASA is only where it is because a politician lied to us and we bought it.
Musk, Rutan, Bigelow et al., they have some innovative ideas, but they're so wrapped up in the superiority of their own ideas, they'll soon be stuck like everyone else gets. There is no amount of money that will make spaceflight cheap or safe until we are no longer dependent on chemical rockets. I get the feeling sometimes we're like a fungus on the surface of this planet, scrabbling frantically to escape. (Too metaphysical?)
Regarding the ego part, seriously who cares if we can put people into space this year or the next if it doesn't get us anywhere, doesn't advance technology, and doesn't inspire? We used to innovate to get into space. Mercury, Gemini, Apollo, all pumped out enormous advances. It makes me sick that 40 years later, I find myself defending space using decades old technology. "What have you done for me lately?" Today we use off the shelf technology so we can afford to do the same thing we did 40 years ago. And for what, more flagpoles and footprints?
NASA needs to be dismantled. I listened to the new Administrator the other day explain how he would expand cooperation with other agencies. Most of it should just be broken apart and absorbed by those agencies: NOAA, FAA, NIH, etc. Space doesn't belong to one agency. Frankly, until a real breakthrough in propulsion is made or a "smoking gun" asteroid is headed our way, there will be no new mission, just a series of underfunded mandates and failed efforts.
Have a nice day!
PS Please don't confuse my pessimism with doubting the talented men and women who continue to work their hearts out to make our current programs look easy. Their hands are tied.
