The SIRIUS Chair is the first international research chair dedicated to the law and management of activities in the space sector

SIRIUS deals with the entire range of regulatory, institutional, economic and management issues raised by the generalization of the social uses of satellites, the opening up of space activities to the competition and the development of commercial applications of space technologies. This is a new approach to space activities, focusing on the latest trends and resolutely oriented toward addressing the needs of industry.

It draws up an inventory and a census of the challenges linked to this emerging industry and offers recommendations that could be implemented at different levels.

Current Research Topics

The SIRIUS Chair favors a "micro" approach as opposed to a "macro" approach. Its work focuses on space companies and the space industrial ecosystem, which is not incompatible with a reflection on the international governance of space activities and its current shortcomings. We use to call on the complementary skills, particularly technical, that we need from the laboratories of the Toulouse university site, as needed.
