UNOOSA launches Space Law 101: Marchisio on the scope of application of national space legislation

11 September 2025

UNOOSA launched its brand-new Space Law 101 campaign, designed to make the fundamentals of national space legislation more accessible to a wider audience. The initiative comes within the framework of the Organization’s ongoing Global Space Law Project, through which UNOOSA has already delivered over 50 tailored legal advisory missions to Member States across every continent.

Sapienza University of Rome and the OSL Team contributed to UNOOSA’s Project, including participation in the Space Technical Advisory Mission to Morocco on 26 September 2024, aimed at supporting the country in developing its national space legislation. This contribution was also acknowledged in the exchange of letters between Driss El Hadani, Deputy Director of UNOOSA and H.E. Ms. Debora Lepre, Ambassador Extraordinary and Plenipotentiary of the Republic of Italy to the UN in Vienna, highlighting the OSL Team’s significant role in the mission.

In one of the videos of this series, Sergio Marchisio sheds light on the scope of application of national space legislation – a cornerstone for regulating space activities. He explains how the scope of application defines to whom, to which activities, and to which places national space laws apply.

🌐 States adopt different criteria (personal, territorial, quasi-territorial, or mixed), and this can sometimes create overlaps – for example, when an operator belongs to one State but launches from another. Recent legislative approaches aim to prevent such conflicts through potential mutual recognition of authorizations, and simplify procedures, thereby facilitating compliance and supporting the growth of emerging actors in the evolving New Space Economy.
