The Consultative Committee for Space Data Systems (CCSDS) & Interagency Operations Advisory Group (IOAG) hosted a Lunar Interoperability Forum on May 7th, 2024 in Washington, DC. with the aim of accelerating the development of all needed international space communication and navigation standards required to ensure multi-national and multi-system interoperability around the Moon. This forum brought implementing organizations and associated industries together with the developers of relevant standards to identify missing standards and methods for the participants to be collectively involved in their development. Applying wider expertise will lead to interoperable prototype and, ultimately, flight systems for the benefit of all space agencies and industrial partners.
