Sustainable Space : Resilient Earth

The guiding theme of the 76th International Astronautical Congress (IAC 2025), Sustainable Space : Resilient Earth, explores the essential connection between space innovation and sustainability. It focuses on three central areas:

• Space-based applications for earth

• Sustainable space activities

• Sustaining life beyond earth

As space technology and research advance, this theme highlights the need for responsible, equitable and forward-looking approaches. The goal is to preserve space for future explorers while ensuring the benefits of exploration flow to all of humanity.

Space technology has become vital for addressing urgent challenges here on Earth. From environmental monitoring and resource management to providing critical data for disaster resilience, space-based solutions are essential for building a sustainable and resilient future for generations to come.

Sustainability in space extends beyond the management of space debris or coordination of space traffic. It also means addressing the environmental impacts of launches and re-entries, ensuring equitable management of space resources, and strengthening international collaboration to keep space accessible and safe for all.
