  What about them? A GRB that takes out Earth would cook Mars even more thoroughly due to its smaller size. I think in practice we will colonise mas but no more than we are colonising Antarctica. The ITS will make going to a Mars affordable and there are good scientific reasons for wanting to do so. But my most optimistic scenario is that we'll have small bases on Mars for at least a generation testing out technology before well even begin to be able to dream about making such a station in any way self sustaining, even just in food, air and water let alone anything more complex.

    Yes, but what percentage of human life on earth is under 2 meters or more of soil? Human life on mars is likely to be underground to avoid the extreme cold, vacuum, and radiation. So I could see a GRB taking out a hugely larger fraction of life on earth (with no warning) than mars (assuming a colony there).
