I was curious, so I looked up NASA's budget over time. For once I don't think we can actually blame Reagan for that budget cut. JFK gets the budget rising, LBJ sees the budget peak and start falling, then Ford and Nixon preside over it continuing to fall and level out and then every subsequent administration except Bush Sr lets it shrink.
@Matt5sean3 @LeftistLawyer @chrisisgr8 Recall that Nixon hated Kennedy, so when budget concerns threatened Apollo 18 and 19, well, that was an easy decision for Nixon to make.
Then the shuttle program came along like an industrial money vacuum hose, and Carter didn't really care about the space program, and Reagan's only semi-creative space thought was Star Wars, which was a defense program. Sigh.....
