Just googled an article, albeit 2018 , NASA doesn't occupy a large portion of the federal budget at all, clocking in at a 0.4% of the 2018 budget. Even then, it's not like the money that goes into NASA is being wasted. Each dollar that goes into NASA adds $7-14 to the economy.

Anybody seen the Wiki-Leaks article on the moon landings , it’s quite interesting.
