Earth is not well. The promise of starting life anew somewhere far, far away beckons, and settling the stars finally seems within our grasp. Or is it? Bestselling authors Kelly and Zach Weinersmith set out to write the essential guide to a glorious future of space settlements, but after years of original research, and interviews with leading space scientists, engineers and legal experts, they aren't so sure it's a good idea. Space tech and space business are progressing fast, but we lack the deep knowledge needed to create space nations in a way that doesn't spark conflict back home. In a world hurtling toward human expansion into space, this book investigates whether the dream of new worlds won't create a nightmare, both for settlers and the people they leave behind.
