FCC approves controversial space mirror test

The Federal Communications Commission (FCC) has approved a test of a potentially disruptive technology, granting California-based startup Reflect Orbital permission to launch and test a satellite equipped with a large mirror designed to reflect sunlight back to Earth after sunset. The approval has drawn significant criticism from astronomers and environmental experts concerned about its potential impact on scientific research and ecological systems.

Reflect Orbital plans to deploy the satellite, featuring an 18-meter-wide thin-film reflector, into low Earth orbit later this year. The company ultimately aims to send up to 50,000 such mirrors into orbit, envisioning their use for powering solar farms, illuminating urban areas, and aiding in rescue operations.

Concerns raised by scientists include the potential for the mirrors to interfere with astronomical observations, which require dark skies. The American Astronomical Society has also warned of potential temporary blinding effects for airline pilots and nighttime drivers. Furthermore, some researchers caution that the reflected light could disrupt the circadian rhythms of both humans and wildlife.

Despite widespread public comments, largely negative, the FCC dismissed these concerns as hypothetical and stated that space activities are not subject to environmental laws. The company, however, argues that the technology could reduce fossil fuel consumption by extending solar power generation hours. The FCC has indicated that future concerns can be raised if the company seeks approval for additional satellites.
