Space has become increasingly crowded since the turn of the century, as a growing number of countries, companies, and even private citizens have begun operating satellites and become spacefarers. Crowded Orbits offers readers a valuable primer on space policy from an international perspective, examining technology, diplomacy, commerce, science, and military applications. This second edition is thoroughly updated to cover events of the decade following the book's original publication in 2014, when the pace of the competition to exploit space has accelerated dramatically.

James Clay Moltz examines the ongoing tension between competition and cooperation in space, tracing the political and policy consequences of key developments. Drawing on decades of experience, he considers possible avenues for collaboration among the growing number of actors as well as the forces driving potential space-related conflicts. Moltz examines the challenges to existing treaties and other governance mechanisms that have struggled to keep up with the spread of technology. He provides policy recommendations to enhance international collaboration, further scientific exploration, and restrain harmful military activities. This edition features analysis of a range of new topics including the ongoing commercialization of space by SpaceX, Planet, and other start-up companies; the U.S. Space Force; climate change monitoring from space; renewed tensions between the United States and Russia, complicated by China's military activities; and multinational competition on the Moon.
