Cleaning up Earth's orbital clutter: a three-front plan to tame space debris
About 13,486 tonnes of debris orbit Earth, with tens of thousands of pieces larger than 10 cm, risking collisions that could trigger a cascading Kessler syndrome and threaten satellites and crewed missions. The article advocates a three-pronged approach: (1) technology and design changes, including active debris removal methods (nets, magnets, tethers, harpoons) and more durable or disposable satellites (even testing wood as a spacecraft material); (2) policy shifts like stricter end-of-life disposal (five-year rule) and stronger space traffic management and debris-mitigation standards; (3) a shift in thinking—treating space as an interconnected environment with ethical obligations, not a limitless frontier. It also notes the rising impact of mega-constellations on debris and ongoing international efforts to reduce risks.
