President Trump is struggling to find a place in history, other than being the worst president his country has ever had. On more than one occasion he has expressed views about returning to the Moon, sooner rather than later. My guess is that he sees an opportunity to make money from whatever resources people might find there.
It’s a bit Kennedy-esque, I suppose, certainly the commitment (if that’s not too strong a word).
We (mankind) landed on the Moon in 1969, and by late 1972 the whole programme was over. Nearly all the men who walked there are dead. The USA achieved something magnificent, but do not have the resources or technology to do it now. With the ending of the space shuttle, they do not have a proven method of getting humans into orbit even.
