Marking a significant expansion in the number of signatories to the Artemis Accords, NASA welcomed Albania, Croatia, Côte d’Ivoire, and San Marino, bringing total participation to 76 countries. 

“Our momentum reflects a growing commitment to peaceful, responsible exploration and a shared understanding that the future in space will be shaped by those willing to lead,” said NASA Administrator Jared Isaacman. “Nearly one-third of all signatories have joined since the start of President Trump’s second term. As the President directs NASA to return Americans to the lunar surface and lay the groundwork for Mars, we are strengthening a coalition of partners who share our values and are ready to help shape the future of exploration.”

The recent surge in growth reflects one of the most rapid expansions of international cooperation in civil space history. Nearly 40% of the world’s nations are now collaborating with NASA to build a transparent, peaceful, responsible, and safe approach to space exploration. Nearly two-thirds of countries that signed the foundational 1967 Outer Space Treaty also have signed the Artemis Accords.  

What began as an informal coalition of a small group of countries has developed into a large, structured community guided by the Signatories Group Method of Operations, adopted in 2024. Under this framework, the group meets twice annually, once at a technical workshop and once at a Principals’ Meeting during the International Astronautical Congress (IAC). Virtual sessions are added throughout the year to support implementation. 

As a result, participating countries have advanced agreed-upon recommendations on noninterference, interoperability, scientific data sharing, and registration practices. 

Two major workshops this year further strengthened technical alignment. Signatories reviewed their planned lunar landings and orbital missions and took part in hands‑on sessions focused on
