NASA, along with leaders from global space agencies and government representatives worldwide, convened on Monday to further the implementation of the Artemis Accords — practical principles designed to guide the responsible exploration of the Moon, Mars, and beyond.

The meeting was held during the 76th International Astronautical Congress (IAC) taking place in Sydney. In opening remarks, acting NASA Administrator Sean Duffy highlighted the five-year anniversary of the Artemis Accords next month.

“When President Trump launched the Artemis Accords in his first term, he made sure American values would lead the way – bringing together a coalition of nations to set the rules of the road in space and ensure exploration remains peaceful. After five years, the coalition is stronger than ever. This is critical as we seek to beat China to the Moon, not just to leave footprints, but this time to stay,” said Duffy.

The United States, led by NASA and the U.S. Department of State, signed the accords on Oct. 13, 2020, with seven other founding nations. The accords were created in response to the growing global interest in lunar activities by governments and private companies. They now comprise 56 country signatories — nearly 30% of the world’s countries.

The event was co-chaired by NASA, the Australian Space Agency, and the UAE Space Agency. Dozens of nations were represented, creating the foundation for future space exploration for the Golden Age of exploration and innovation.

“Australia is a proud founding signatory of the Artemis Accords and is focused on supporting new signatories in the Indo-Pacific region,” said Head of Australian Space Agency Enrico Palermo. “The purpose of the accords is as important — if not more important — as it was when first established. This annual gathering of principals at IAC 2025 is a key opportunity to reaffirm our collective commitment to exploring the Moon, Mars and beyond in a peaceful, safe, and sustainable way.”

During the meeting, leaders discussed recommendations for non-interference in each other’s space activities including transparency on expected launch dates, general nature of activities, and landing locations. They also discussed orbital debris mitigation and disposal management, interoperability of systems for safer and more efficient operations, and the release of scientific data.

In May 2025, the United Arab Emirates hosted an Artemis Accords workshop focused on topics, such as non-interference and space object registration and reporting beyond Earth orbit.

“Through our active participation in the Artemis Accords and by organizing specialised workshops, we aim to reinforce the principles of transparency, sustainability, and innovation in space activities. We are committed to strengthening international partnerships and facilitating the exchange of expertise, thereby contributing to the development of a robust global framework for safe and responsible space exploration, while opening new frontiers for scientific research,” said UAE Minister of Sports and Chairman of UAE Space Agency Ahmad Belhoul Al Falasi. “This reflects the UAE’s unwavering commitment to enhancing international cooperation in space exploration and promoting the peaceful use of space.”

More countries are expected to sign the Artemis Accords in the months and years ahead, as NASA continues its work to establish a safe, peaceful, and prosperous future in space.

At the International Astronautical Congress (IAC) taking place in Sydney this week, representatives from the United States and Australia gathered to sign a framework agreement that strengthens collaboration in aeronautics and space exploration between the two nations.

Acting NASA Administrator Sean Duffy and Australian Space Agency Head Enrico Palermo signed the agreement Tuesday on behalf of their countries, respectively.

“Australia is an important and longtime space partner, from Apollo to Artemis, and this agreement depends on that partnership,” said Duffy. “International agreements like this one work to leverage our resources and increase our capacities and scientific returns for all, proving critical to NASA’s plans from low Earth orbit to the Moon, Mars, and beyond.”

Australian Minister for Industry and Innovation and Minister for Science Tim Ayres said the signing builds on more than half a century of collaboration between the two nations.

“Strengthening Australia’s partnership with the U.S. and NASA creates new opportunities for Australian ideas and technologies, improving Australia’s industrial capability, boosting productivity, and building economic resilience,” Ayres said.

Known as the “Framework Agreement between the Government of the United States of America and the Government of Australia on Cooperation in Aeronautics and the Exploration and Use of Airspace and Outer Space for Peaceful Purposes,” it recognizes cooperation that’s mutually beneficial for the U.S. and Australia and establishes the legal framework under which the countries will work together.

Potential areas for cooperation include space exploration, space science, Earth science including geodesy, space medicine and life sciences, aeronautics research, and technology.

NASA has collaborated with Australia on civil space activities since 1960, when the two countries signed their first cooperative space agreement. The Canberra Deep Space Communication Complex played a vital role in supporting NASA’s Apollo Program, most notably during the Apollo 13 mission. Today, the complex is one of three global stations in NASA’s Deep Space Network, supporting both robotic and human spaceflight missions.

One of the original signatories to the Artemis Accords, Australia joined the United States under President Donald Trump and six other nations in October 2020, in supporting a basic set of principles for the safe and responsible use of space. Global space leaders from many of the 56 signatory countries met at IAC in Sydney this week to further their implementation.

As part of an existing partnership with the Australian Space Agency, Australia is developing a semi-autonomous lunar rover, which will carry a NASA analysis instrument intended to demonstrate technology for scientific and exploration purposes. The rover is scheduled to launch by the end of this decade through NASA’s CLPS (Commercial Lunar Payload Services) initiative.

NASA’s international partnerships reflect the agency’s commitment to peaceful, collaborative space exploration. Building on a legacy of cooperation, from the space shuttle to the International Space Station and now Artemis, international partnerships support NASA’s plans for lunar exploration under the Artemis campaign and future human exploration of Mars.
