The legal regime of outer space, as enshrined in the Declaration of Legal Principles Governing the Activities of States in the Exploration and Use of Outer Space (General Assembly Resolution 1962 (XVIII), adopted in 1963, and in the 1967 Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies, while prohibiting the appropriation of space by any means, envisages exploration for the bene?t and in the interest of all countries on a basis of equality and in accordance with international law. Freedom of scienti?c investigation is also contemplated. Elaborating on these instruments, the Assembly in 1996 adopted the Declaration on International Cooperation in the Exploration and Use of Outer Space (RES 51/122), in which it called for heightened international co-operation, with part- ular attention to be given to the bene?t for and the interests of developing countries and countries with nascent space programmes. Thus, it is self-evident that the outer space regime, including the 1972 Liability Convention, envisages the conduct of national activities “for the bene?t and in the interests of all countries, irrespective of their degree of economic or scienti?c dev- opment”. In this regard, Article 6 of the 1967 Treaty not only provides for national activities in outer space, but for international responsibility whether such activities are carried out by governmental agencies or non-governmental entities, and aims at ensuring that national activities are conducted in conformity with the Treaty.
