I still don't know the plan for orbit refilling. Everyone says they'll induce spin of the crafts, but how much propellent will that take? They're heavy as fuck, couldn't be a small amount. And then the mating points; they'll have to be strong to keep hundreds of tons of metal from not tearing away from itself.

It's not physically impossible but I'm interested in the numbers on their solutions, as it pertains to dV with more mass or more propellant to make it happen.
