SpaceX and Reflect Orbital satellite plans threaten to eliminate Earth's night sky, scientists warn

SpaceX proposes launching up to 1 million satellites for space-based AI data centers, while Reflect Orbital plans to deploy reflective mirrors in orbit, potentially transforming night into day globally. Scientists warn these megaconstellation projects could severely disrupt human circadian rhythms, wildlife migration patterns, and entire ecosystems dependent on natural darkness. The initiatives raise urgent questions about space governance and environmental stewardship as commercial space ventures accelerate without international regulatory frameworks. Astronomers and environmental groups are mobilizing opposition, but no binding international treaties currently restrict such satellite deployments.
