One of Saturn’s moons may be our best option for life after Earth
It’s several hundred years into the future. You live in a cold climate, but thick clothing keeps you warm. You eat food from the community greenhouse. Sometimes you even go boating, spending tranquil days under the orange sky. Life is similar in some ways to how it is now. In other ways, it’s very different. For one thing, you can fly. Also — your body is now permanently incapable of adapting to Earth’s atmosphere, and you can never return.
