Ariane 6 is set to be the next flagship launch vehicle of the European Space Agency (ESA). On 30 November 2023, after years of delays and unfortunate circumstances, ESA Director General Josef Aschbacher finally announced that the rocket’s first flight will take place in the summer of 2024 (Foust, 2023d). [VI1] Ariane 6 is designed to carry into orbit payloads commissioned by private contractors, national governments, ESA member states and the European Union Space Programme (EUSPA). It aims to replace the recently retired Ariane 5 rocket, which was entrusted with the delivery of Europe’s heaviest and most advanced payloads during its 117-flights-long career from 1996 to 2023  (ESA, n.d. - a).

Space law is a complex system governing outer space activities which comprises international treaties, conventions, United Nations General Assembly resolutions, as well as rules and regulations of international organisations. This paper will lay the international legal framework of space law, examining key documents like the Outer Space Treaty (OST) of 1967. Beyond this legal framework, the paper explores the militarisation of outer space, scrutinizing the intersection between space law and the evolving military activities taking place in outer space.
