In May 2020, NASA announced a sweeping new set of principles designed to safeguard the use of outer space titled the Artemis Accords. Seeking to ensure transparency and peace in outer space, facilitate international cooperation, and encourage sustainable lunar resource extraction, the Accords “establish a common set of principles to govern the civil exploration and use of outer space.” These principles also include requirements that space activities are interoperable, scientific data is shared, nations commit to providing emergency assistance, and that historical sites are preserved as artifacts.
In contrast to the 1967 Outer Space Treaty (OST) and the 1979 Moon Agreement, the Artemis Accords are not a new multilateral treaty, but principles that build upon the legal foundations set by the OST. Moreover, NASA intends to enshrine these principles with partner nations through the process of bilateral cooperation and general state practice. In other words, the act of nations accepting these principles through their cooperative ventures with the United States will help calcify norms into international law, even without a legal instrument.
However, the purportedly noble goals of the Accords have not evaded skepticism among some spacefaring nations, particularly the People’s Republic of China.
