The numbers
- 76 signatories after the four latest countries joined.
- According to NASA, nearly 40 percent of the world's nations now take part.
- Nearly two thirds of the countries that signed the 1967 Outer Space Treaty have also signed the Artemis Accords.
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.Jared Isaacman, NASA Administrator
How the signatories work together
Since 2024, the group follows the Signatories Group Method of Operations. It meets twice a year, at a technical workshop and at a Principals' Meeting during the International Astronautical Congress, with virtual sessions in between. According to NASA, the countries have advanced recommendations on noninterference, interoperability, scientific data sharing and registration practices. This year's workshops covered planned lunar landings and orbital missions and practical tools for sharing lunar data.
Next step: IAC 2026 in Antalya
The Artemis Accords Principals' Meeting at IAC 2026 in Antalya, Türkiye, begins on 5 October. It will be co-chaired by NASA Deputy Administrator Matt Anderson and Major General Roberto Melgar Sheen, director of the Peruvian Space Agency CONIDA. Topics include support for emerging space nations and lunar debris mitigation recommendations.
What signatories commit to
- Explore peacefully and transparently.
- Render aid to those in need.
- Enable access to scientific data.
- Ensure their activities do not interfere with others.
- Preserve historically significant sites and artifacts.
