FCC approves test of space mirror to light night sky

The U.S. Federal Communications Commission (FCC) has approved a test of a space mirror designed to reflect sunlight onto Earth at night, potentially illuminating urban areas or providing emergency lighting. The project, led by Reflect Orbital, involves a small satellite with a deployable reflective surface that will be tested in low Earth orbit. The test is scheduled for late 2026, with the mirror expected to create a spot of light several kilometers wide on the ground. The approval marks a regulatory milestone for space-based illumination technology, though environmental and astronomical concerns have been raised about light pollution and disruption to nocturnal ecosystems. The company has stated the technology could reduce energy costs for street lighting and aid disaster response.

Global Impact

Economically, successful space mirrors could disrupt the $100 billion+ global street lighting market by offering a cheaper, off-grid alternative, though initial costs remain high. Environmentally, the technology risks exacerbating light pollution, affecting wildlife migration and astronomical research, potentially triggering international treaties on orbital light emissions.
