“[Engdahl] has been a space migration advocate for decades. This book is an excellent assembly of her writings...related to that theme.” –Amazon review. For 50 years, space advocates have been frustrated by the slowness of progress in space and the failure of the public to grasp its importance not only to the future of humankind, but to the preservation of Earth's environment. This book includes all of Engdahl's earlier essays about space, plus new ones about the priority of Mars and the question of whether we'll ever meet hostile aliens. From $0 SHOP NOW /
