Overview
- The FCC authorized radio and communications operations for one demonstration satellite, Eärendil‑1, and denied petitions to block that single test.
- Eärendil‑1 is a roughly 142 kg craft that will unfurl an about 18‑meter thin‑film reflector from low Earth orbit to direct sunlight to a scoped ground spot.
- Reflect Orbital says the demo will test beam control, rapid shutoff, targeting limits and safety measures that it claims will contain light and avoid sensitive sites.
- Astronomers and biological researchers warn models show large fleets could greatly raise night‑sky brightness, disrupt telescopes and alter animal and human circadian rhythms.
- The demonstrator’s empirical data will guide other agencies and public reviews and will shape whether the company’s goal of tens of thousands of mirrors can move forward.
