Can humanity overcome the depletion of Earth's natural resources and overpopulation by harvesting the vast wealth of the solar system? John Lewis, a professor of planetary sciences, presents a rigorous argument that the technological capacity to mine asteroids, comets, and planets is not only feasible but imminent. He utilizes data from planetary science and engineering to demonstrate how extraterrestrial resources can sustain human civilization indefinitely.

Experts in the field of space resources recognize this work as a foundational text for understanding the economic and technical viability of off-world mining. Readers frequently note the balance between accessible prose and the dense scientific data provided to support the author's claims.
