To help pay for his War on Vietnam, Tricky cancelled the Apollo program, which included Apollo 18 and 19.

Cheapened the shuttle from a liquid propellant booster to the solid rockets that were liable to expode. Manned space flight was never the same.

And the crook HATED President Kennedy.
Nixon nixed commissioning Apollo 11 "The John F. Kennedy"
(Blogger Machodoc) Came across an interesting tidbit at the Archives yesterday, specifically in Kissinger's National Security space files.
It seems that in early summer 1969 Bill Moyers, after reading an article in Newsday, wrote Pat Moynihan to ask if he could convice President Nixon to christen the Apollo XI the "John F. Kennedy". Moynihan agreed, sent a memo to up the chain of command, where before it finally reached the White House received a couple of additional endorsements.
On June 12 the proposal reached John Ehrlichman's desk, and in a memo to H. R. Haldeman, wrote: "Unlike Daniel P. Moynihan, I can see no advantage to the President to commission the Apollo 11 moon shot the "John F. Kennedy." We would win neither friends in Congress no votes in 1972 and would only become pawns in the press's game of perpetuating the name of JFK. Fall prey to this and the next step will be renaming the moon because NBC thinks it would be a good idea."
The next day, in a memo to his boss, Haldeman, Steve Bull agreed, an in his memo said that "we have gone far enough in "Kennedyizing" such ventures."
In the action box at the bottom of the page, in the space recommending the action be abandoned is Haldeman's "H", with a note in strong handwriting and double underlined, "positively!!"
