FCC Approves Reflect Orbital's Space Mirror Satellite Despite Strong Astronomer Opposition

The U.S. Federal Communications Commission has approved a California-based startup's plan to launch a giant space mirror satellite designed to reflect sunlight to Earth after dark, despite receiving over 1,800 public objections from astronomers, environmental groups, and safety advocates. The satellite, named Earendil-1, is a demonstration mission intended to test technology that could power solar farms at night or illuminate disaster zones during rescue operations.

The Satellite and Its Scope

Reflect Orbital received FCC authorization to launch and operate the satellite in low-Earth orbit using the requested radio spectrum. The spacecraft will carry a steerable thin-film reflector measuring approximately 60 feet by 60 feet, designed to cast reflected sunlight across an area roughly 3 to 5 kilometers wide on the ground. The satellite must reposition itself every four minutes to maintain the reflected beam. This single test mission represents only the initial phase of a far more ambitious plan: the company envisions deploying more than 50,000 satellites in orbit by 2035, effectively creating a network of mirrors encircling Earth to provide continuous nighttime illumination and solar energy collection across agricultural, industrial, and emergency response sectors.

Widespread Concerns from the Scientific Community

The approval process triggered substantial opposition from established institutions and advocacy groups. The American Astronomical Society raised multiple safety and scientific concerns, including potential eye damage to amateur astronomers using telescopes, temporary flash blindness affecting pilots and drivers during the satellite's periodic repointing maneuvers, and interference with federally funded astronomical facilities conducting critical research. Additional concerns centered on disrupted circadian rhythms in plants, animals, and humans caused by artificial nighttime illumination, as well as damage to sensitive detectors in research telescopes and star-tracking cameras aboard lower-altitude satellites that could be overloaded by the reflected light.

The FCC acknowledged receiving substantial public commentary on the application but determined that concerns about the solar reflector fall outside its regulatory authority. The Commission stated in its approval order that such harms are "unlikely to occur" and that the agency's role is limited to authorizing radiofrequency spectrum use. The FCC emphasized that approving the demonstration satellite aligns with U.S. policy to "encourage the provision of new technologies and services to the public" and represents a potentially groundbreaking innovation supporting American leadership in space technology.

The Broader Context of Space Commercialization

The satellite approval occurs amid a broader wave of unconventional commercial space ventures now emerging in low-Earth orbit. Nearly 11,000 SpaceX Starlink satellites currently orbit above Earth, and regulatory frameworks are adapting to accommodate increasingly novel proposals—from orbital data centers and pharmaceutical manufacturing in space to artificial meteor showers and space-based advertising. The FCC recently published a document titled "Spectrum Abundance for Weird Space Stuff" acknowledging the reality that once-fictional concepts are now becoming operational business plans backed by private companies seeking investor funding.
