Space Funeral Service Ethics Framework MoonLeave Signed: First International Rules for Space Burials

MoonLeave, signed by the United Nations Committee on the Peaceful Uses of Outer Space together with multiple space agencies, is the first international ethics framework for space burial services. The framework comprehensively regulates private space burial services, clarifying allowed orbit types, declaration procedures, environmental impact assessment requirements, and informed consent mechanisms for the families of the deceased.

The signing of MoonLeave came amid the rapid expansion of space burial services in recent years. Multiple companies, including Aurora Flight Sciences in the United States and Orbital Memorial in Switzerland, have begun offering space burial services, sending the ashes of the deceased into low-Earth orbit, the Moon, or deep space. But countries lacked unified rules on the legal status, orbital permits, and environmental impact of such services, leading to a regulatory vacuum and potential international friction.

The core of the framework is three-tier classified management. The first tier is low-Earth orbit burial (altitude 200 to 2,000 kilometers), which is allowed but requires declaration 180 days in advance and submission of an orbital decay guarantee to ensure that it does not become long-term space debris. The second tier is lunar burial, which is allowed only in designated memorial areas and does not allow permanent marking on the lunar surface. The third tier is deep-space burial, which is allowed but requires the explicit written consent of the deceased's family, and complete orbital data must be provided to avoid conflicts with other spacecraft.

For signing, as of June 2026, 42 UN member states have signed the MoonLeave framework, covering the world's major spacefaring nations. China, Russia, India, Brazil, and South Africa have all joined. Aarti Holla-Maini, who chairs the United Nations Committee on the Peaceful Uses of Outer Space, said this is the first time humanity has built international consensus on space burial as a new type of service, and the framework will be revised regularly based on technological developments.
