The science fiction element (other than the Jovian location) lies in the physical transmutation through biological science of humanity into life forms capable of living in hostile environments. It is interesting though because of its subversion of that ideal. A 1944 story about human settlement of the planets which is of its period in postulating a 'patriotic' (though to a species, our own, not a nation) willingness to sacrifice oneself for the sake of the future - albeit that we have the absurdity of sacrificing fit young males who are the future.
