Does the colony really need to be on the planet? Why not start on the orbit? We already do it to some extent, can't we try to grow it? Is the spinning disk ok for artificial gravity or the diameter would have to be extremely large?
Another alternative could be floating, suspended or at the bottom of the ocean colony.
It's like doing test driven development.

- w-ll 10y agoIf we were to invest in building a underwater 'Sealab' on the bottom of some ocean floor, say at least 100m water deep, what kind of cataclysmic event could destroy it. A few dozen of the underwater sea-colonies seams the most practical safety net for humanity that we can do today. I completely for exploring and colonizing space, but we still haven't mapped our own oceans fully. And sadly, I don't think my generation, or even the next few will be any closer to being able to get ourselves off this rock. If you are looking to build 'Arks' for humanity, i'd put my money on the ocean floor.

- vbezhenar 10y agoIs it hard to nuke Mars or Titan? Looks the same for me. Deploy nukes in the Mars orbit and destroy colony if needed.
- mrfusion 10y agoWe sort of already have this. Nuclear submarines. I wonder if they've ever planned for repopulating the earth? They should carry frozen embryos on board.
