Artemis Accords expand to 76 nations as four more countries commit to peaceful space exploration

On September 28, 2026, NASA announced that the Artemis Accords reached a new milestone as four more nations joined the group. With the addition of Albania, Croatia, Côte d’Ivoire, and San Marino, the international coalition now includes 76 participating countries. This expansion reflects a broadening global commitment to peaceful, transparent, and responsible space exploration. NASA Administrator Jared Isaacman noted that the momentum behind the accords demonstrates a shared understanding that the future of space will be shaped by a collaborative community. With nearly 40% of the world's nations now involved, the accords represent one of the fastest expansions of international cooperation in the history of civil space activity, helping to unify the approach to lunar and deep-space missions.

The Artemis Accords were established in 2020 by the United States and seven other founding nations to create a framework for the safe and sustainable exploration of the Moon, Mars, and beyond. These principles are rooted in the 1967 Outer Space Treaty, and today nearly two-thirds of that original treaty's signatories are also members of the Artemis Accords. What began as an informal coalition has since become a structured international body, guided by the Signatories Group Method of Operations adopted in 2024. This framework supports regular communication through twice-yearly meetings and technical workshops, ensuring that as more nations develop space capabilities, they do so within a set of agreed-upon standards that prioritize safety and scientific cooperation.

Putting the accords into practice involves specific measures designed to improve mission success and reduce the risk of conflict. Over the past year, signatories have participated in technical workshops focused on noninterference, interoperability, and the sharing of scientific data. These sessions allowed experts from dozens of countries to work through practical scenarios, such as standardizing lunar data formats to make information easier to access globally. By adopting common standards, nations can ensure that their equipment and systems are compatible. This interoperability is essential for assisting astronauts in need and for building long-term infrastructure like the planned Moon Base. These hands-on efforts translate high-level principles into functional tools for mission planners and scientists.

The benefits of this growing coalition extend beyond technical coordination to include environmental and social impacts. One primary focus for the group is the development of recommendations for lunar debris mitigation, intended to preserve the lunar environment for future generations. The accords also provide a platform for emerging space nations to gain expertise and participate in high-profile missions. NASA has invited all signatories to contribute to lunar exploration through scientific payloads, technology demonstrations, and the deployment of CubeSats. This inclusive approach allows countries with developing space programs to benefit from the experience of established agencies while contributing their own innovations to the global effort.

Looking forward, the Artemis Accords will continue to serve as a foundation for international space diplomacy. The upcoming Principals' Meeting at the International Astronautical Congress in Antalya, Türkiye, will be a key venue for discussing the next steps in lunar exploration. Co-chaired by NASA Deputy Administrator Matt Anderson and Major General Roberto Melgar Sheen of the Peruvian Space Agency, the meeting will focus on supporting new members and refining practices for noninterference in lunar activities. As NASA prepares to return humans to the lunar surface and eventually reach Mars, the strengthening of this 76-nation coalition ensures that these milestones will be achieved through a peaceful and collaborative international framework.
