That's all well and bottled up until you realize that the "heavy lift rocket" you glaze over at the very end IS SOMETHING YOU CAN'T EVEN LEAVE LOW-EARTH ORBIT (much less go to the Moon or any place else) WITHOUT.
At best you can say that President Obama has kicked the "NASA Can" down the road a little, but to suggest he's somehow tying their hands is ludicrous.
As little as 12 months from now we could well have PRIVATE CORPORATIONS able to supply human access to low-earth orbit (which is all you need to reach the ISS, do any type of larger construction in the event you choose to go to the Moon, Mars, etc.) -- NASA DOESN'T NEED TO WASTE MONEY ON THAT.
Thirty years ago, yes -- the Space Shuttle was one hell of a deal (even with its cost over runs and greatly exaggerated capabilities) -- but now it's 100% superfluous and the only reason to continue flying it is out of nothing but pride -- and pride is something you've got to get over if you want to do great things.
What's ultimately going to happen with NASA, I have no idea. But five years from now (perhaps as few as three) they will have the technical capability to do anything we can dream of (Private Launchers to send astronauts into space, their own Heavy Launch Vehicle to go farther, etc.) -- all we'll have to do is choose our destiny!
See -- :) -- I bet you thought I was going to be all mean, didn't you?
