But that's the failure to meet the primary requirements of the challenge. The question is how much people, money and materials (mass) is required to avoid dropping the TL by more than 1 by the time the new generation grows up.

As I said, disregard the transportation costs themselves if they're fiddly. Just name your requirements for manpower, funding and mass. I bet many people would be interested in this scenario from a Spaceships PoV, but I think being more generic is better.

At TL9 and TL10 this isn't much of a challenge because of 3D-printers and Infomorphic lifeforms (which basically reduce survival minimum to that of a Von Neumann machine with the data to build a bioroid and some ghosts archived somewhere).
