FCC Approves Sun-Reflecting Orbital Test, Sparking Astronomers’ Alarm

The FCC authorized Reflect Orbital’s Eärendil-1, a 142‑kg satellite that will deploy an 18-meter reflector to redirect sunlight to nighttime regions for testing, with potential uses from construction lighting to boosting solar farm output. Proponents say it could advance space testing and utility lighting, but astronomers and environmentalists warn it could brighten the night sky, disrupt diurnal cycles, and interfere with telescopes and wildlife. The FCC said environmental and astronomical impacts fall outside its review but noted commitments to NASA/NSF collaboration and community consultation; public comments were largely critical, and petitions for a broader environmental assessment have been filed as the company contemplates thousands of future satellites.
