O estas con ellos , o estas en contra de las vacas pastando calmamente por toda la semana . <| sep |> It ' s not though . It ' s a frequently perpetuated myth that you ' d need a magnetic field and so a molten core in order to make Mars habitable again . It ' s true that the lack of a magnetic field is what killed Mars off in the first place no magnetic field no protection from the solar wind atmosphere was lost to space but it certainly isn ' t necessary for us Because it took hundreds of millions of years for the solar wind to eat away at the Martian atmosphere . And us humans only live for a hundred years at best . We could just pump the Martian atmosphere full of oxygen and nitrogen right now and the rate of atmospheric loss will be so slow edit 100 grams a second . it honestly doesn ' t matter , it wont be a problem we ' ll have to worry about for millions of years
