One of the key principles of the Outer Space Treaty is that space is the common heritage of humanity and cannot be owned by anyone – government, nation, individual or corporation. Space is very colonial: we talk of the ‘conquest’ of space, the ‘high frontier’ or the ‘final frontier’, colonising other planets, and the innate urge of human beings to explore, often without thinking about it; it’s such a strong master narrative. Instead of considering the treaty to be outdated, we might equally think of it as a radical statement of equality and justice – and one we need more than ever.
