One thing that space exploration detractors seem to have a difficult thing comprehending is exactly what happens to money spent on a space program. Seemingly, they are under the delusion that all that money gets stuffed into a rocket and blasted into space, never to be seen again.

Of course the material cost of the rocket stages and probes/satellites is quite small, the vast majority of money spent on space exploration is spent on earth. Paying earth engineers earth dollars that they will in turn spend on earth. That 25 Billion USD Apollo program? That money didn't get sent to the Moon, damn near all of that money was spent in America.

Hell, think of it this way: India needs satellites, so they can either dump money into another country that will build and launch those satellites for India, or they can dump that money back into India and develop those capabilities themselves. How could you possibly fault India for keeping their space money domestic?
