In recent years, the EU Space Strategy for Security and Defence has assumed paramount importance, driven by shifts in the geopolitical landscape and the imperative to update collective policy approaches. In this context, the enlargement of NATO and the ramifications of the Russo-Ukrainian war pose significant questions (Kolovos, A., 2023). More specifically, these geopolitical shifts underscore the urgent need for a unified defence system against potential common threats. This is an especially complicated task considering that the space domain presents nuanced challenges akin to those of the Arctic, where borders lack the tangible delineation seen in traditional realms of air, land, or maritime boundaries. In this sense, the new approach to space defence and security includes both military considerations and political and legal dimensions.
