I have been developing an advanced civilization inhabiting a world orbiting a gas giant about 3 times the mass of jupiter, the conditions have already been tuned to allow life to develop over its surface to the point of giving rise to intelligent beings.
I have been wondering if it would be plausible that they started utilizing their gas giant as a source of advanced resources, such as helium-3, as they started becoming space farers.
With space farers I don't mean interstellar specie, but mainly starting to colonize their star system, building outposts on the other worlds and within the asteroid belt, think about 'The Expanse' but with most of the population being concentrated on the homeworld and no settlemnt being truly self sufficient. As for technology, again think like 'The Expanse' if only just a bit more advanced featuring quantum computers, nanotechnology, cybernetics, biotech, advanced robotics and AI.
To give you a better idea of the situation:
Gas giant mass: 3 times the mass of jupiter
Moon mass: 0.7 earths
Distance: 1002864 kms or 544000kms
Do you think it would be plausible that they'd have facilities extrating helium 3 and similar compounds from their gas giant? And in case it weren't, do you think they could ever do that with more advanced technology?
