They would be up there all the time Americans are far too bigheaded to just leave it at that!
That's not strictly true.. the Saturn V rocket and F1 Engines dwarf any rocket that's been built ever since.. no rockets have actually been capable of getting there.
The F1 Engines were also predominantly hand built, no Lazer or computer technology, believe it or not engineering skills have been lost since those engines were created.. computers have built similar engines but not in such a basic yet perfect form.
Watched a documentary on it, it's literally that the F1 Engines are incredibly difficult to re create.. yes they could get there again but the cost is and will be insane.. and for what? Not much more to do up there, creating a colony would be great.. but would need a multi national program to pay for it.
That being said, I thought there was talk of going back in the next few years?
