I have to say I hope this would never be possible . <| sep |> The two are about the same , but with Marry Christmas on extra twinkle is seen in the eyes . <| sep |> Yes . How silly of me . It is all meaningless , as the heat death of the universe will in the end take us all . Should ' ve realised it earlier . <| sep |> That ' s literally the worst reason to disqualify Mars . The good reasons to disqualify Mars are the fact that it has less than 1 % of Earth ' s atmospheric pressure and no magnetic field . Gravity ? Who cares . As long as the gravity isn ' t higher than earth ' s , humans can survive in it just fine . We have astronauts living in 0 g on the space station for long periods . They ' ll lose some muscle mass and bone density , but only as much as they don ' t need it to move around in the lower gravity environment . Although I ' d agree not to discount Venus . There are some interesting ideas regarding landing structures on the atmosphere of Venus that would just float in the atmosphere like a submarine because of Venus ' extraordinarily high atmospheric pressure . There is a magnetic field and you wouldn ' t have to worry as much about depressurization .
