Story summary

Reflect Orbital plans to launch an 18-meter test satellite, Earendil-1, in 2026, as part of its proposed satellite constellation to beam sunlight to Earth.
The company aims to deploy approximately 4,000 satellites by 2030, which could create light pollution brighter than the full Moon, affecting astronomy and wildlife.
Tests suggest that achieving the desired illumination levels is impractical, necessitating thousands of satellites for minimal light, raising concerns about the project's feasibility and its impact on the night sky.
