Where is it?
From a leading planetary scientist and an award-winning science writer, a propulsive account of the developments and initiatives that have transformed the dream of space colonization into something that may well be achievable.

We are at the cusp of a golden age in space science, as increasingly more entrepreneurs--Elon Musk, Richard Branson, Jeff Bezos--are seduced by the commercial potential of human access to space. But Beyond Earth does not offer another wide-eyed technology fantasy: instead, it is grounded not only in the human capacity for invention and the appeal of adventure but also in the bureaucratic, political, and scientific realities that present obstacles to space travel--realities that have hampered NASA's efforts ever since the Challenger disaster.

In Beyond Earth, Charles Wohlforth and Amanda R.Hendrix offer groundbreaking research and argue persuasively that not Mars, but Titan--a moon of Saturn with a nitrogen atmosphere, a weather cycle, and an inexhaustible supply of cheap energy, where we will even be able to fly like birds in the minimal gravitational field--offers the most realistic and thrill#65533;ing prospect of life without support from Earth.
