INTRODUCTION. This article examines the space laws adopted by Luxembourg in 2017 and 2020, which allow private persons, subject to the conditions provided by these laws, to explore and use the natural resources of celestial bodies. At the same time, the authors proposed an international legal assessment of these laws.MATERIALS AND METHODS. The study of the designated laws of Luxembourg is based on the scientific works of domestic and foreign specialists in international space law, especially in terms of the analysis of previously adopted national legislation on space activities. Both general scientific methods of cognition and methods of legal sciences, including formal-legal and comparative-legal, are used. RESEARCH RESULTS. The analysis of Luxembourg laws in the general context of applicable international law presented in the article shows that these laws have basically adopted the new US legal space policy, initially outlined in the US Commercial Space Launch Competition Act of 2015.

DISCUSSION AND CONCLUSIONS. International legal issues of the use of outer space, including those affecting the status of celestial bodies, have long been resolved at the universal level, primarily on the basis of the Outer Space Treaty of 1967. The situation has changed with the involvement of the United States since 2020 of an increasing number of states in a separate treaty-legal regime of space activities created by the Artemis Agreements, concluded by the United States with more than 40 states. These agreements, in turn, adopted the basic provisions of the new US legislation on natural resource activities in space, starting with the aforementioned US Law of 2015. The basic “space” laws of Luxembourg - the Law on the Exploration and Use of Space ...
