Scientists have been working out ways to move humans from Earth to other planets with Mars being the most likely destination.
However, Titan, Saturn’s largest moon, is Earth-like as it is covered in liquid and has a thick atmosphere that could protect future inhabitants from the sun’s deadly solar flares.
And analysis has now shown that it is abundant in radioactive decay which initial settlers could use to create nuclear power.
They could then use its hydrocarbon lakes to generate even more power, which could support a settlement of up to 300 million people, according to experts from the Johns Hopkins University in Maryland.
Planetary scientist Ralph Lorenz said Titan should be the next stop after Mars.
He told New Scientist: “I think long-term, after Mars, Titan’s probably the next most important place that people will have an extended presence.
“As a resource for long-term, solar-system-wide civilisation, Titan would be a pivotal place.”
Saturn’s gravitational pull also creates strong tides on Titan, which could be used for hydropower.
Dr Lorenz added: “We’re pretty sure there’s a very strong flow of liquid back and forth every Titan day.
“If you want reliable power that you know is going to be accessible, that’s where I would go.” […]
