The Space Sustainability Paradox 

Understanding the Space Sustainability Paradox

What is the Space Sustainability Paradox?

The space sustainability paradox is the idea that while space activities help address sustainability issues on Earth, they also contribute to making space itself unsustainable.

Earth Sustainability involves the responsible use of natural resources to support both present and future generations. Space Sustainability refers to maintaining the long-term health and viability of space activities by using space resources responsibly, minimising debris, and ensuring space remains accessible for future generations.

Challenge in Space Sustainability 

Space Debris

One of the most pressing issues in space sustainability is space debris. Thousands of defunct satellites and fragments orbit Earth, posing collision risks to operational satellites and spacecraft.

Anti-Satellite (ASAT) Weapons

Adding to the problem is the use of ASAT weapons, which can destroy satellites, creating thousands of pieces of debris that further complicate space traffic management.

Addressing the Challenges

Monitoring and Tracking

Companies like LeoLabs monitor satellites and other debris in real-time, using ground-based technology to track their locations and monitor potential signs of malfunction. This helps manage space traffic and mitigate collision risks.

Active Debris Removal

The UK, in line with its National Space Strategy, has initiated Active Debris Removal (ADR) mission studies with companies like Astroscale and ClearSpace. These missions aim to develop technologies for removing defunct satellites and large debris from space, ensuring safer space operations.

Astroscale

Astroscale, founded by Nobu Okada, is a pioneer in in-orbit servicing. The company is working on solutions to manage satellites that have reached the end of their life, remove large debris, and develop future refuelling and recycling services. With a global team, Astroscale is committed to creating a safer space environment for future generations.

ClearSpace

Founded in 2018, ClearSpace is revolutionising space missions with technologies for disposal, in-orbit transport, inspection, assembly, manufacturing, repair, and recycling. ClearSpace has been selected by the UK Space Agency to develop an Active Debris Removal mission, which will advance key technology building blocks and develop commercially viable disposal services.

Regulatory Framework

Safe, secure, and sustainable practices in space require an agreed set of rules, regulations, and guidance. The UK has launched a consultation on orbital liabilities, insurance, charging, and space sustainability. This initiative aims to develop a longer-term sustainability roadmap and establish sustainability principles through the Earth∞Space Sustainability Initiative.

Conclusion

Space sustainability is a pressing issue that demands immediate action. From international cooperation to innovative technologies, various avenues are being explored to implement sustainable practices in space. As we continue to benefit from space activities, we must also take responsibility for ensuring that space remains viable and accessible for future generations.
