Space sustainability is becoming a defining principle for how space activities are designed, launched, operated, and governed.

It is essential for both securing the future of space missions and ensuring that the benefits of space continue to support life on Earth. It is also our responsibility to protect the environments we interact with – on Earth, in orbit, and on other celestial bodies such as the Moon.

With increasing launch rates, growing congestion in orbit, and expanding exploration missions, the space sector faces urgent sustainability challenges. These developments call for transformative approaches to reduce environmental impacts on Earth, use resources more efficiently in space, and manage waste responsibly beyond our planet.

This panel will not stop at highlighting the problems. The focus is on practical solutions. Representatives from a diverse group of space agencies will present concrete objectives and strategies designed to mitigate risks and enhance sustainability. Topics will include climate impacts, the protection of dark and quiet skies, and the mitigation of orbital debris, all viewed through the lenses of technological innovation, international cooperation, and regulatory development. Key questions to be explored include:

• How are space agencies integrating sustainability into their strategies and missions?
• In what ways do priorities vary across regions, and what can we learn from these different approaches?
• Which initiatives are already being implemented to support responsible and long-term space activities?

Featuring perspectives from the European Space Agency, Australian Space Agency, NASA, Korea Space Agency, and Philippine Space Agency, this panel aims to encourage meaningful action toward a sustainable space sector – one that remains accessible, safe, and beneficial for future generations.
