Future Space Colony? Maybe We Should Look Beyond Mars to Saturn's Titan Moon

NASA and Elon Musk’s SpaceX are focused on getting astronauts to Mars and even one day establishing a colony on the Red Planet — but what if their attention is better directed elsewhere? A new paper in the Journal of Astrobiology & Outreach suggests that humans should instead establish a colony on Titan, a soupy orange moon of Saturn that has been likened to an early Earth, and which may harbor signs of "life not as we know it." "In many respects, Saturn's largest moon, Titan, is one of the most Earth-like worlds we have found to date," NASA says on its website. "With its thick atmosphere and organic-rich chemistry, Titan resembles a frozen version of Earth, several billion years ago, before life began pumping oxygen into our atmosphere." To be clear, Titan could have microbes — or, at the least, chemistry that resembles prebiotic life — but it is no Earth. The moon is perpetually covered in an orange cloud, and its atmosphere is not human-friendly. But Titan's gravity is walkable (14 percent that of Earth), radiation on the surface is less than on Mars due to its thick clouds, and it offers various sources from which visitors might generate energy. As the paper's author, Amanda Hendrix, pointed out in a previous book that she co-authored, Beyond Earth: Our Path to a New Home in the Planets, Titan has massive deposits of hydrocarbons — compounds generally associated with petroleum and gas. Data from NASA's Cassini probe has shown that Titan has hundreds of times more liquid hydrocarbons than all of the known oil and natural gas reserves on Earth. Read More: Live Science
