FCC Clears a Giant Space Mirror to Beam Sunlight at Night - Astronomers Warn of the Risks

The U.S. FCC has authorized Reflect Orbital to deploy and operate Eärendil-1, an experimental satellite carrying an 18-by-18-metre steerable reflector. The single-satellite test could demonstrate tightly targeted sunlight from orbit, but astronomers argue that its brightness, safety implications and regulatory precedent demand far closer scrutiny.
