What is Space Law and Policy?


Space Law


Any discussion or enquiry into space law usually begins with the Outer Space Treaty of 1967.[1] This treaty has been described as a ‘cornerstone’ or ‘Magna Carta’ of outer space[2]. It provides the foundational legal framework upon which the space governance regime has been built. Many of its provisions, Articles I-IV and VI especially, are now considered to be customary international law which generally means that even states not party to the Outer Space Treaty have an obligation to respect or abide by the provision.[3] The Outer Space Treaty was further developed by three subsequent treaties, the Rescue Agreement[4], the Liability Convention[5], and the Registration Convention[6]. The Moon Agreement[7] is the fifth of the United Nations space law treaties, but it is largely considered a ‘failed’ treaty given the low number of States Parties to the treaty. However, it is inaccurate to call it a ‘dead’ treaty as it continues to pick up new parties such as Venezuela in 2016 and Armenia in 2018.[8] Additionally, the treaty is in force and is therefore binding upon its parties.


Beyond the space treaties there are a few other treaties such as the ‘Partial Test Ban Treaty’[9] of 1963 which also has application in outer space, as well as a host of UN Resolutions and so-called ‘soft law’ instruments which also have applications and relevance to activities in outer space. Additionally, many states have national legislation regarding activities in outer space, such as the UK’s Outer Space Act 1986[10] and Space Industry Act 2018[11]. The United Nations Office of Outer Space Affairs (UNOOSA), secretariat to the UN Committee on the Peaceful Uses of Outer Space (UNCOPUOS), has an excellent resource on space law, including texts of the treaties and relevant UN Resolutions and documents on it’s website, here.




The United Nations Committee on the Peaceful Uses of Outer Space (UNCOPUOS) is the UN Committee responsible for international cooperation in the peaceful uses of outer space. It has two subcommittees, the Scientific and Technical Subcommittee, and the Legal Subcommittee. These meet annually in Vienna. UNCOPUOS was the originator of the five ‘United Nations’ Treaties on Outer Space (the Outer Space Treaty, the Rescue Agreement, the Registration Convention, the Liability Convention and the Moon Agreement.) It continues to be an important focal point for the discussion of international issues of space governance and continues to grow in membership. More details can be found here.


Space Policy


Policy itself is not an easy term to define but it can essentially be defined as a course of action or inaction which provides a context and guidance for future decision making[12]. Space policy is a subset of policy in general and helps to set the focus and direction of a state’s space efforts. Space policy overlaps, intertwines and interacts with general science, technical and industrial policy. There are also significant security interests in the space sector, both as a tool for the armed forces (surveillance, communications, global navigation etc) but also as a national infrastructure asset that requires protection. As space becomes increasingly important in our daily lives and for the economy space policy is gaining increasing prominence, importance and relevance.
