A record number of Artemis Accords signatories, including the United States, gathered at the International Astronautical Congress (IAC), the world’s largest global space conference taking place in Milan this week, furthering discussions on the safe and responsible use of space for the benefit of all.

During the space conference, top space agency leaders and other government representatives met on Oct. 14 to continue advancing the implementation of the Artemis Accords, marking the most comprehensive engagement yet among Accords signatories.

“As we send humans further into the solar system, collaboration and shared responsibility among nations are more critical than ever,” said NASA Deputy Administrator Pam Melroy. “The Artemis Accords provide a common sense set of principles to guide our work together, and our recent efforts to further their implementation is fostering a remarkable environment of trust and cooperation where all nations can contribute to and benefit from these endeavors.”

The high-level meeting was co-chaired by NASA, CSA (Canadian Space Agency), and the Italian Space Agency. With 42 of 45 signatories participating, established and emerging spacefaring nations from every region of the world were represented to help create a foundation for future space exploration for the Artemis Generation.

Leaders from each nation reflected on how the group can contribute to and advance existing multilateral forums, further technical discussions to inform policy deliberations, and promote and encourage the participation of emerging space nations including the adoption of the Artemis Accords by additional countries. They agreed on recommendations on non-interference, interoperability, release of scientific data, long-term sustainability guidelines, and registration to advance implementing the Artemis Accords. A method of operation was established for the ongoing work of the signatories.

“Promoting the participation of emerging space nations and encouraging the adoption of the Artemis Accords is crucial for the entire space,” said Teodoro Valente, president of the Italian Space Agency. “This is a matter of strategic importance in order to ensure the active and meaningful engagement of emerging space nations, both those already part of the Artemis Accords, and those poised to join in the future.”

The conversation in Milan built on previous work during a workshop in Montreal in May 2024, where participants delved into topics such as non-interference and interoperability.

“Canada is pleased to be part of a growing group of countries committed to the safety and sustainability of outer space activities,” said Lisa Campbell, CSA president. “We are strong supporters of the Artemis Accords and are pleased to have hosted the most recent workshop that advanced work on key aspects of the Artemis Accords. We look forward to continuing this important work in the coming months and years.”

In October 2023, signatories agreed on an initial set of mission data parameters to advance transparency and non-interference in conducting space activities. The data parameters identify relevant information about planned lunar surface missions including expected launch dates, the general nature of activities, and landing locations. Recent progress also included work on a database to house them. Several space agencies, including NASA, have submitted mission data to the United Nations Office of Outer Space Affairs for dissemination.

Potential focus areas for the next year include further advancing sustainability, including debris management for both lunar orbit and the surface of the Moon.

In 2020, the United States and seven other nations were the first to sign the Artemis Accords, which identified a set of principles promoting the beneficial use of space for humanity. The Artemis Accords are grounded in the Outer Space Treaty and other agreements including the Registration Convention, the Rescue and Return Agreement, as well as best practices and norms of responsible behavior that NASA and its partners have supported, including the public release of scientific data. 

The commitments of the Artemis Accords and efforts by the signatories to advance the implementation of these principles support the safe and sustainable exploration of space.
