Space Capabilities for Sustainability on Earth




At the first ever Global Space Leaders Summit, organized by the International Astronautical Federation at the IAC2024, the theme was "Space Capabilities for Sustainability on Earth". All space agencies leaders were invited to contribute with a brief statement and this was my contribution:

Mr. Chairman, Mr. President, dear Teodoro, thank you so much for organizing this seminal event. I am very happy to address our colleagues today.  

        The space age, which began 67 years ago with the launch of artificial satellites, initially captivated humanity with visions of exploration beyond Earth. Yet, those very tools designed to venture outward have quickly become vital for looking inward, for observing and protecting our own planet.              

Over the past decades we have been witnessing how space capabilities become increasingly important in addressing the pressing challenges of sustainability on Earth. From mitigating climate change to enhancing resource management, the use of space technology offers unparalleled solutions to some of our most urgent global and regional problems.

The Hellenic Space Center, the National Space Agency of Greece, has been supporting the government in the implementation of its first small-satellite constellation that will carry a comprehensive set of Earth Observation sensors, both passive and active, which will decisively contribute to critical national needs related to sustainability. Real-time data will allows scientists and policymakers to make informed decisions on issues ranging from agriculture to urban development to natural disasters. 

Similar initiatives around the globe - such as the Copernicus program of the European Union and various national Earth observing satellites - underscore a worldwide trend to using space technology to meet sustainability goals.

Space exploration itself drives innovation in sustainable technologies. The challenges of sustaining life in space - such as water recycling, air purification, and energy efficiency - often lead to breakthroughs that can be applied here on Earth. For example, advanced water filtration systems developed for astronauts have been adapted for use in regions with limited access to clean water.

Finally, space capabilities offer an expanded perspective on sustainability. The famous "Earthrise" photograph, taken by Apollo astronauts, continues to remind us the fragility of our planet. This view from space emphasizes that Earth is a finite, interconnected system, encouraging a global commitment to preserving its ecosystems. 

As we look to the planets and stars, it is essential that we continue investing in and leveraging space technologies to safeguard Earth’s ecosystems and ensure a sustainable future. The lessons learned in space, and the technology developed for exploration, must also be used to preserve the only home we have - our planet.
