I don't know the ins and outs, will an orbital be self-sustaining enough to last for the years/decades/centuries? until earth is habitable again?

  Requisite mention of Seveneves by Neal Stephenson. He doesn't seem to think much of Mars settlement.

    To be fair, it's not too enlightening to learn from fictional evidence.

      True. About Mars, it's just an expression of his opinion. But I gather that he did research the stuff about orbital habitats and such.
