> All your crew and all your materials are ultimately coming from Earth Wait till we start making LOX (and later, I think, metals) on the Moon from regolith. The process is old and tested on Earth, the missing part is actually experimenting with this on the Moon. And as soon as we have more or less robust Earth-Moon transportation, this will become important, as it will significantly simplify near Moon operations. Do you know NASA runs, right now, competitions for e.g. lunar ice extraction and purifying?
