Abstract: There are some defects in the current legal system concerning the ownership of recovered space mineral resources, and the domestic unilateral legislations of the United States and other countries have violated the outer space treaty system. In addition, international legal regulations are vague, and the existing theories cannot guarantee and promote the development of outer space resources. The key to improving the ownership of recovered space mineral resources is to acknowledge that various countries should be the first subject of the rights of the recovered space mineral resources under the United Nations outer space system, and private entities or non-governmental organizations can claim their ownership or usufructuary rights on this basis. Various countries should mutually recognize the resource rights and enrich the connotation of resource priority, so as to construct a space resource management system with national property rights as the core.
