The Cislunar Security Conference (CLSC) is a forum on the technology, policy, doctrine, and strategy implications of ensuring free access to, transit to, and use of the Earth-Moon system beyond geosynchronous equatorial orbit. Space is quickly becoming an even more critical part of the nation’s scientific and national security agendas, with increased attention on activities in the vicinity of the Moon and on its surface. The goal for this conference is to encourage national-level technical discourse related to domain awareness; policy and strategy; communications and infrastructure; trajectory design; threats; and position, navigation, and timing (PNT) for cislunar security. Abstracts are due July 31. Registration closes September 29. Visit Access Requests are due October 2.
