Sad but true.

Only if you assume the reason justified going back again.  A plant-the-flag
expidition like Apollo, or a survey mission, would only need one trip.

You still run into the problem of needing a pretty much selfsuficent system.
That takes a lot more manufacturing stuff, which needs more parts, needs more
skilled people, and other geometric etc..

Then don't go by train.  Most of our systems could get their once and back
easier and cheaper then going their and seting up infastructure.

Me neiather.
