The Regulation of Commercial Space Tourism Under International Space Law: Challenges, Gaps, and the Need for a Comprehensive International Legal Framework

Commercial space tourism has evolved from a futuristic concept into an emerging global industry driven by private aerospace companies such as Blue Origin, Virgin Galactic, and SpaceX. Successful suborbital flights have demonstrated that commercial human spaceflight is no longer limited to government astronauts but is increasingly accessible to paying private individuals, creating significant opportunities for technological innovation, economic growth, and international cooperation. This transition, however, has also exposed deficiencies in the international legal framework governing outer space. The five principal United Nations space treaties were negotiated between 1967 and 1979, at a time when states were the exclusive actors in space exploration, and they contain little guidance on private commercial spaceflight, passenger status, insurance, or environmental protection. This article examines the adequacy of that framework in regulating commercial space tourism, evaluating the legal status of spaceflight participants, the allocation of liability among states and private operators, passenger safety standards, insurance requirements, environmental sustainability, and consumer protection. Through comparative analysis of national regulatory approaches in the United States, the United Kingdom, the United Arab Emirates, Japan, and Nigeria, the article demonstrates that domestic law alone cannot effectively govern an inherently transnational industry, and that the resulting fragmentation creates legal uncertainty for operators, insurers, and passengers alike. The article argues that the rapid commercialization of outer space has outpaced the development of international legal norms, and that without a harmonized regulatory framework, uncertainties surrounding liability, jurisdiction, passenger rights, and environmental protection will continue to constrain the industry’s sustainable growth. It concludes by recommending the negotiation of a dedicated international convention on commercial human spaceflight under the auspices of the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS), supported by harmonized safety, licensing, liability, and environmental standards, and considers the particular position of developing spacefaring nations such as Nigeria within this emerging regulatory landscape.
