In Beyond Earth: Our Path to a New Home in the Planets, Charles Wohlforth and Amanda R. Hendrix propose colonizing Titan, the largest moon of Saturn, and the second largest moon in the solar system. They reject constructing colonies on Mars and the Moon, claiming Titan offers the most resources for creating a permanent human settlement.
Even though I don’t buy their premise, Wohlforth and Hendrix have written a book that nicely sums up the current knowledge on human space travel. What’s damning and depressing is their long litany of obstacles we face living in space. Over the years I’ve read news reports about the various dangerous health effects of space travel, but reading them all in one place makes me wonder if science fiction is completely wrong about the future of humans in space.
Oddly enough, near the beginning of their story, Wohlforth and Hendrix report books on space colonization are never taken seriously by professionals in the space industry. Evidently, such wild ideas are a danger to the careers of real space scientists. Wohlforth and Hendrix say books about colonizing space give amateur space enthusiasts hope, but those folks lie on the fringe, closer to science fiction fans than scientists. I’m a space enthusiast and a science fiction fan, so Beyond Earth is my kind of book, but I couldn’t help taking this news as a slight.
