We lived through loads of questions regarding aquatic races, so buckle up, I am going to gather some ideas around insectoids.
The homeworld and race
- This race lives on a planet which has lower gravity than Earth (0.8 g)
- The planet is hostile in environment, so an exoskeleton is the best evolutionary advantage
- Oxygen level is on oxygen level of Paleozoic Era
- So the race living here either evolved from insect, or at least looks like insect
- The race definitely lives in a hive and is hive-minded
- And I want them to "shoot for the Moon"
When I set the definition of their home world and their mindset, I have to explain "why would they want to shoot for the Moon?"
If their home world was a stand alone planet with a moon, I could be hoping for a Phobos-sized moon, which makes no sense whatsoever to go there.
So, the different idea is: The moon is a different moon of the same planet, and we are already on a moon.
But is it plausible?
Is it plausible to have a gas giant in the habitable zone of a Sun-sized star? Would there be any drawbacks for life to start on one of the moons of such a planet?
Edit: To clarify: I am thinking of a setup, where the main planet is a gas giant the size of Jupiter or bigger. And the homeworld planet is orbiting around it as one of its moons.
