I don ' t know about that . Mars has less than 1 % the atmospheric pressure of earth and no magnetic field . So if you lose pressurization , you ' re dead . And your structure would have to be shielded or you ' d get cancer . Either way you ' re stuck living in a can . The more interesting question is which one would be easier to terraform ? Venus has a magnetic field which is a good start since there ' s literally nothing we can do about that . So is it easier to create 1 atmosphere or make 89 of them go away ? <| sep |> i always have room for that . <| sep |> the one that came with the case . <| sep |> I got the best saving rate today , 100 % off . I bought nothing . <| sep |> don ' t worry . probably even before he takes office the others will come around too . I ' m guessing he ' ll be impeached before the first year .
