Im making a sci-fi video game set in the not so distant future. In this future mankind has begun to set up settlements in moons in the "far rim" which is the nick name given to the planets outside of the asteroid belt. I want to have a couple of at least half accurate theories to Terra form various moons. Right now all I have is a settlement in Europa because it was the most obvious. Id also prefer if you tried to use more simple terms/explain your difficult terms, im no scientist Also try to think of resources that could be gained from the planet. For example on Europa there are facilities that use nuclear fission to tear H2O apart into oxygen and use it for future terraforming projects with a more "local source" (the logic doesnt have to be 100% sound, just have a couple of interesting and theoretically possible points)
