Startup Plans Satellite Mirrors to Reflect Sunlight onto Earth’s Night Side

California-based startup Reflect Orbital plans to deploy up to 50,000 satellites equipped with large, motorized mirrors in sun-synchronous orbit to reflect sunlight onto Earth’s night side. The technology aims to illuminate areas after sunset, potentially aiding solar power, rescue operations, and urban lighting. While the company envisions reducing fossil fuel use, some scientists have raised concerns about the concept’s feasibility and environmental impact. Prototypes are in development, with larger deployments planned by 2030.
