Abstract

As space systems increasingly perform and support critical operations, a variety of plausible near-term incidents in outer space could precipitate or exacerbate an international crisis. The most grave space contingencies—viewed from the perspective of U.S. interests and international stability—are likely to result from either intentional interference with space systems or the inadvertent effects of irresponsible state behavior in outer space. The threats to U.S. space assets are significant and growing, as potential adversaries continue to pursue and could soon acquire counterspace capabilities. The United States has strategic interests in preventing and mitigating dangerous space incidents, given its high reliance on satellites for a variety of national security missions and unparalleled global security commitments and responsibilities. Like other technology-driven global governance challenges, the longer the United States delays preventive and mitigating efforts, the less dominant its position will be in shaping rules of the road for space.
