The dual-use capacity of many space assets and technologies is bolstering the weaponisation of space and becoming a great threat to satellites and space-based services. Therefore, the militarisation of space presents security risks and technical, diplomatic and legal challenges. This paper delves into the challenges that weaponisation of space pose to the proliferation of space debris in orbit and the risk of triggering the Kessler Syndrome from a legal perspective. Consequently, this article proposes updating the international legal framework to regulate the behaviour of space actors, restrict the location in space of space weapons and assets as well as to ban certain weapons.
