Description
The rapid expansion of space activities has revolutionised technology and exploration but also poses significant sustainability challenges. Space debris, environmental impact, and inefficient resource use threaten the long-term viability of near-Earth operations. Emerging technologies offer solutions to these challenges, driving a shift toward responsible space practices.
This talk explores three key innovations in space sustainability: active debris removal (ADR), biodegradable satellite materials, and sustainable launch practices. ADR systems, such as NASA's ADRV and Airbus's RemoveDEBRIS project, use robotic arms, nets, and harpoons to capture and remove defunct satellites, reducing collision risks and preventing debris accumulation.
Next, biodegradable materials—like Japan's wooden LignoSat and ESA’s fiber-reinforced panels—offer an eco-friendly alternative to traditional satellite components, ensuring safe decomposition upon reentry without compromising durability.
Finally, advancements in sustainable launch systems, including reusable rockets by SpaceX and 3D-printed rockets by Relativity Space, significantly cut manufacturing waste and carbon emissions, making space access more sustainable and cost-effective.
By integrating these innovations with strong governance frameworks and interdisciplinary collaboration, the space industry can transition toward a circular economy, preserving the orbital environment and setting a precedent for responsible exploration beyond Earth.
