2026 Cislunar Security Conference

The seventh annual Cislunar Security Conference (CLSC) will be held December 1-3 at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland.

As national priorities and global competition accelerate beyond Earth orbit, cislunar space serves as a critical domain for American leadership and strategic advantage. Driven by the Executive Order on Ensuring American Space Superiority, the establishment of the U.S. Space Force Cislunar Coordination Office, and NASA’s expansive lunar initiatives, CLSC 2026 will convene leaders from government, industry, and academia to uncover the technologies, partnerships, and policies required to enable sustained operations, mission assurance, and space superiority across the cislunar domain. From space domain awareness and resilient communications to logistics, infrastructure, and security cooperation, participants will drive action today to shape tomorrow’s operational and strategic advantage in space.
