The Principle of International Cooperation and Sharing of Information Principle under International Space Law: Towards Synergy

Throughout the history of the astronautic development, one of the key principles of international space law has always been the principle of international cooperation between States. The States jointly, although sometimes in conditions of competition or in a tense geopolitical situation, systematically moved towards the development of space science and technology, and the exploration of outer space for the benefit of all mankind. To succeed in this difficult task, the principle of information sharing has always served as an assistance to the principle of international cooperation. A striking example of how the two outlined principles are applied is the protection of the International Space Station against a possible collision with space debris. As a number of States consider exploring more celestial bodies and deep space, the importance of the principles of international cooperation and information sharing is increasing. This article focuses on these principles and their complementary roles. The first part of the article provides a retrospective analysis of the principle of international cooperation and the manner in which it is enshrined in international law, including international space law. The second part explores the principle of information sharing as a particular example of the principle of international cooperation. The conclusion of the article is that in current conditions, there is an increasing need for strict adherence to the designated principles for the realization of space activities in general as well as ensuring its safety and efficiency. © 2023 Elsevier Ltd
