In the context of an incresingly congested, contested and competitive space environment, security in outer space has become a clear priority of space agendas in the United States and Europe. In this respect, the year 2018 has been marked by a number of major developments on each side of the Atlantic (e.g. U.S. Space Traffic Management policy, SSA component of EU space programme...) with far-reaching implications for respective approaches to rising space security challenges. Although motivated by different policy rationales and characterised by a lopsided state of affairs, both Europe and the United States asserted their willingness to actively progress on the different issues at stake.

Well aware that a fully effective approach to space security can only be envisioned as the outcome of a coherent and inclusive global effort, both U.S. and European policies call for a reinforcement of international cooperation in this field, and in particular with each other. From this perspective, recent and foreseen developments in this field offer a fertile ground to revisit transatlantic relations in space security towards a reinforced cooperation seeking mutual benefits.

ESPI Public Report 66 "Security in Outer Space: Perspectives on Transatlantic Relations" provides an overview of the current state of play, including a comparative analysis of U.S. and European landscapes and a review of existing transatlantic cooperation frameworks, and investigates the implications of recent policy developments for transatlantic relations in this domain.
