The blistering pace of innovation in space, including the unprecedented growth of the population of Low Earth Orbiting satellites continues to advance unabated. Accompanying this new space boom are increasingly urgent calls for governance of this regime, or at least norms, guidelines, or standards to ensure safety, security, and sustainability of space for the benefit of all. Since 1959, the International Telecommunication Union (ITU), has been continuously developing new treaty law provisions to address the sustainability of spectrum and orbital resources while enabling new space services. The ITU’s Radio Regulations are updated every four years by the World Radiocommunication Conference (WRC) to accommodate new services and technologies. The ITU will convene the next WRC in 2023 in the United Arab Emirates. This paper will inform how the ITU continuously updates space law to accommodate emerging space services while preserving sustainability of shared resources in the specific context of the challenging agenda of WRC-23.
