Outer Space Security Conference 2026

Secure World Foundation was pleased to once again co-organize the Outer Space Security Conference 2025 (OS25) in partnership with the United Nations Institute for Disarmament Research (UNIDIR). This annual event brings together government officials, technical experts, civil society representatives, commercial leaders, and academics for candid, cross-sector dialogue on the evolving challenges facing space security.

Outer space is entering a renewed phase of strategic importance, defined by rapid innovation, growing competition, and deepening global dependence. The evolution of the domain into a site for critical infrastructure and diverse commercial participation is fundamentally reshaping how space is accessed, used and governed. At the same time, the dual nature of modern space activities creates complex security dilemmas regarding the thresholds of destabilizing activity, the neutrality of new actors, and the strategic usage of space data. These developments raise urgent questions about security and stability in orbit.

Against this backdrop, UNIDIR convenes the Outer Space Security Conference 2026 as a platform for meaningful exchange across policymakers, defence actors, industry, academia and civil society. Through focused panel discussions on technical, legal and policy dimensions, participants will explore practical pathways to strengthen the security and sustainability of outer space, ensuring it remains stable and accessible for all.
