Congress authorizes spending and appropriated federal dollars on a line-item basis. I.e., how that money is spent is explicitly dictated by Congress.
Again, no. Congress appropriates federal dollars on a line-item basis specifically directing how dollars are spent.They give X to NASA, but they don't stipulate what research or programs that X amount of money is spent on. If they don't like it, they could decrease X; but they don't. Once the money is appropriated, NASA spends it on the things the President wants done.
Nope.NASA is under the mandate of the President, it does as the President tells them to.
NASA cannot spend any federal dollars on it until Congress says they can.If the President says "manned mission to Mars", NASA has to work towards a manned mission to Mars.
The entire point here is exposing your ignorance.Congress won't slash their budget because of it. The entire point was that NASA should no longer be under the mandate of the President. If we're going to have NASA, it needs to be run by the scientists. I don't see why I should spend my money on a bunch of worthless programs that aren't scientifically viable.
Example, when Kennedy said NASA was going to the Moon, NASA didn't just start working on it. Congress had to appropriate funding for it.
