FCC Approves Test of Giant Space Mirror

The Federal Communications Commission (FCC) has granted a California startup, Reflect Orbital, permission to test a satellite equipped with a 60-foot-wide mirror in low Earth orbit later this year. This satellite aims to reflect sunlight back to Earth after sunset, with the ultimate goal of deploying up to 50,000 such mirrors. The company envisions these mirrors powering solar farms, illuminating urban areas, and aiding rescue operations.

Despite the FCC's approval, the project has faced significant opposition. Astronomers, represented by the American Astronomical Society, have raised concerns that the mirrors could interfere with astronomical research by compromising dark skies essential for observing deep space. They also warned of potential "flash blinding" for airline pilots and nighttime drivers. Other scientists have cautioned about disruptions to the circadian rhythms of humans, animals, and plants, impacting sleep, migration, and blooming cycles.

The FCC received over 1,800 public comments on Reflect Orbital's application, with the majority expressing negative sentiment. The American Astronomical Society explicitly stated that the proposed activities would impact the Earth's environment, including human health, agriculture, and wildlife, in addition to astronomy. However, the FCC dismissed these concerns as "hypothetical" and asserted that activities in space are not subject to environmental laws.
