From brilliant young polymath Andrew Rader - an MIT-credentialed scientist, popular podcast host, and SpaceX mission manager - an engaging” (Tim Marshall, New York Times best-selling author) chronicle showcasing our human desire to continually explore new and uncharted territory, from civilization’s earliest days to interstellar travel.

For the first time in history, the human species has the technology to destroy itself. But having developed that power, humans are also able to leave Earth and voyage into the vastness of space. After millions of years of evolution, we’ve arrived at the point where we can settle other worlds and begin the process of becoming multi-planetary. How did we get here? What does the future hold for us?

Divided into four accessible sections, Beyond the Known examines major periods of discovery and rediscovery, from Classical Times, when Phoenicians, Persians, and Greeks ventured forth; to The Age of European Exploration, which saw colonies sprout on nearly every continent; to The Era of Scientific Inquiry, when researchers developed new tools for mapping and traveling farther; to Our Spacefaring Future, which unveils plans currently underway for settling other planets and, eventually, traveling to the stars.

A mission manager at SpaceX with a lively voice, Andrew Rader is at the forefront of space exploration. As a gifted historian, Rader, who has won global acclaim for his stunning breadth of knowledge, is singularly positioned to reveal the story of human exploration that is also the story of scientific achievement. Told with an infectious zeal for traveling seeking new horizons, Beyond the Known is “an astute - and highly flattering - view of human aspirations” (Kirkus Reviews).
