As far as extraterrestrial bodies go, Saturn's largest moon is surprisingly like Earth, with a dense atmosphere that could shield delicate earthlings from radiation, reports New Scientist. Titan's candidacy as a settlement isn't new, but a fresh analysis shows the yellow moon has valuable energy sources that could power a settlement.
Per Science Alert, Amanda Hendrix and Yuk Yung write that once propulsion issues of getting there are tackled, Titan is the "optimal location in the solar system for an off-Earth human settlement." Some 808 million miles away, self-sustainability on Titan is key. Robots and even humans could one day make nuclear power by using radioactive decay there. The scientists say solar power could come from a US-sized solar farm, even though Titan is nearly 10 times farther from the sun than Earth is.
