Declaration of legal principles of the activities of states in the exploration and use of outer space. According to the Declaration, the sectoral principles of international space law are:
1) the exploration and use of space for the benefit and in the interests of all mankind;
2) openness of the cosmos and celestial bodies for development by all states on the basis of equality;
3) the inadmissibility of the national appropriation of the cosmos and celestial bodies;
4) the compliance of space activities with international law;
5) the international responsibility of States for national space activities, including the activities of non-governmental organizations;
6) cooperation and mutual assistance of states in the exploration and use of space;
7) preservation of state jurisdiction and control over their space objects and their crews while in space;
8) the responsibility of the state launching the space object for the damage caused by them;
9) recognition of cosmonauts as "messengers of mankind" into space and assisting them in the event of an accident, including their immediate return to the launching state.
The principle of abstinence of states from placing objects with nuclear or other types of weapons of mass destruction in outer space is reflected in later resolutions of the UN General Assembly.
