I was reading this thing about the whole conspiracy about how we didn't go to the moon. They claimed one of the reasons was because the saturn 5 rocket didn't have enough fuel for it... however once you're in space and have reached the speed you want to be at, can't you just cut the engines and you'll continue to fly in cruise control with nothing to slow you down? I dunno... you can talk about the conspiracy if you want too, is this in the right place though?
