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.
The Children of Time books by Adrian Tchaikovsky have a lot of those themes. Half of the first book is about an ark ship sent out to find a habitable planet because earth is dying. It spans hundreds of years as key crew members go in and out of hyper sleep. Relationships and political factions form and dissolve as the ageing ship continues its mission to find a new home.
The second book focuses on a terraforming crew that was sent to another star system to prepare a planet for humans. However, the planet’s ecology is so alien it proves very difficult to gain a foothold.
I’ll second this (though I’ve only read the first thus far). I don’t know that I’d consider it especially hard SciFi but it’s far from a space opera. I recall feeling like the justification for the creation of the arachnid race was a bit hand-wavey, but the level of thought put into their society more than made up for the required suspension of disbelief. Definitely one of my favorite books.
For something similar I’d also recommend Dragon’s Egg by Robert L. Forward. It’s about the discovery of intelligent life on a neutron star, who develop at a rate exponentially faster than humanity. Also not super hard SciFi, but a great exploration into truly alien life.
I really enjoyed the first and could not get into the second in the children of time series
