US firm plans 50,000 mirror satellites to illuminate Earth's night side

European Southern Observatory and Slovak Academy confirm light pollution calculations

3 Yesterday · 1d ago · 1 post · 1 source · development 3 of 3

Scientists from ESO Garching and the Slovak Academy of Sciences release findings: a single mirror satellite's light would exceed full-moon brightness levels when observed from 14 kilometers away. Laser physicist Jechow confirms atmospheric scattering will spread light widely—even the initial 0.1 Lux target achieves full-moon level visibility, with later phases reaching daylight brightness.
