Imagine building a shield in orbit to protect Earth against environmental destruction — a fleet of cooperative satellites forming a massive umbrella that reduces solar energy reaching Earth, mitigating the impacts of climate change. This might sound like science fiction or a politically impossible dream, but it’s neither. It’s an engineering and governance challenge the global space community can solve, given sufficient will and urgency. The growing challenge of climate change demands action across multiple fronts. Earth-based strategies such as carbon capture, emissions reduction, and energy transitions remain the primary…
