Oh, I was thinking of fuel minning. If you want to manufacture things from
local resources, you'll need to do some ore refining. Since you'll need to do
more of that for a 1-way mission, you can't save any weight by leaving that
stuff off. On the other hand in a one way mission you don't need to do fuel
minning and processing. So for the sake of argument I was assuming a couple
thousand tons of specialized equipment just for that.
