The UK Space Agency has announced new Associate Members to international committees
The Australian Space Agency (ASA) and the Spanish Space Agency (Agencia Espacial Española, AEE) have officially joined the Inter-Agency Space Debris Coordination Committee (IADC) as Associate Members. The announcement was made by the UK Space Agency, which currently chairs the IADC, on 23 September 2025.
The addition of ASA and AEE marks a continued expansion of global cooperation on space debris, one of the most pressing challenges in space.
International collaboration
The IADC is a long-standing international forum that brings together space agencies from around the world to conduct coordinated research into the causes, risks, and solutions associated with space debris. Founded over 30 years ago, the Committee currently includes 13 full Member Agencies and, since 2024, has introduced an Associate Member status to broaden participation.
The new associate members join the New Zealand Space Agency, which became the first associate member following the creation of the new membership tier. This expansion shows a growing global interest in space sustainability and highlights the increasing importance of international collaboration in addressing the challenges posed by debris in Earth’s orbit.
Focusing on space sustainability
Space debris, comprising defunct satellites, spent rocket stages, and fragments from past collisions, poses a significant threat to operational satellites and the safety of future missions. The IADC plays a crucial role in mitigating these risks through collaborative research, forecasting debris evolution, and developing best practices for spacecraft design and operations.
One of the IADC’s most impactful contributions is the development of the Space Debris Mitigation Guidelines, which have become a global reference for space agencies and commercial operators. The guidelines help shape national and international regulations aimed at reducing the long-term risks of orbital debris.
The involvement of more countries, especially those with growing space sectors, ensures a broader base of knowledge, resources, and perspectives in the fight to maintain a safe and sustainable space environment.
UK taking charge
As the current Chair of the IADC, the UK Space Agency has taken an active role in shaping international dialogue on space sustainability. The Agency’s leadership extends beyond the IADC, with continued involvement in global forums such as the United Nations Committee on the Peaceful Uses of Outer Space (UNCOPUOS).
In addition to its policy and diplomatic work, the UK is investing in a range of technical and scientific initiatives related to space sustainability.
Including Australia and Spain in the IADC signals the increasing international recognition that space debris is not just a technical challenge but a shared global responsibility. By strengthening international ties and welcoming new contributors, the IADC is better positioned to guide efforts to safeguard the orbital environment for future generations.
As more nations develop space capabilities, participation in collaborative initiatives like the IADC will be essential to ensuring space remains a safe, sustainable, and accessible domain for all.
