I’m looking to get inspiration for my own writing. I need a hard sci fi series where earth (and earthlike worlds) are too rare, inaccessible, and/or previously spoiled beyond ability to sustain life. Bonus points if it is set on a multi-generational space station or starship without any other options and goes into detail about life support, living space, mineral mining and expansion of the station to accomodate a growing population, and daily life of it’s residents.
If anyone remembers Drifter Colonies from Titan A.E., that’s what’s in my head.
I’m looking for The Martian levels of realism, and I’m fine with a bit of “Unobtanium” clichés if they’re not core to the story.
Really pretty well-supported by current science, too. I teach chemistry at a community college, so maybe I’m an outlier, but I read a ton of current research about the importance of diversity in “gut biomes” and the damaging effects of monoculture on global ecology, etc.
It seems pretty clear that even if engineers could solve the physical and chemical issues with a generation ship, the limiting constraints are almost certainly going to be biological and ecological, and KS Robinson’s estimates for the upper limits seem pretty reasonable based on current knowledge
