> My prediction that they quickly will go to specialized LEO-LMO vehicles with LEO re-fueling. Two comments here. First, we assume now SpaceX is going to have Starship HLS - human landing system - which doesn't go back to Earth, doesn't have flaps or heat shield, and is going to be used between low Moon orbit (LMO) and Moon surface - maybe one roundtrip, maybe more. Yes, for each following roundtrip HLS needs to be refueled. Second, Musk mentioned "Moon base Alpha" in his talk. Having a serious Moon base makes it possible to produce some of propellants there. Oxygen is plentiful in the form of oxides on the Moon, and by mass it's 2/3 - 3/4 of the propellant load of the Starship, so it might be useful to produce it on the Moon.
