FCC approves space mirror test despite safety, environmental concerns

The Federal Communications Commission has approved a test satellite that will bounce sunlight back to Earth like a cosmic mirror, despite warnings from astronomers, safety experts, and the public that the technology poses serious risks to aviation, astronomy, and the atmosphere itself.

The company Reflect Orbital received clearance to launch Earendil-1, a reflective satellite designed to concentrate the sun's rays onto specific areas of Earth roughly five kilometers wide. The light would serve dual purposes: generating extra solar energy and providing illumination for industrial and emergency applications. The satellite would need to reposition itself every four minutes to maintain its beam. This is not a one-off experiment. Reflect Orbital has announced plans to deploy more than 50,000 such satellites by 2035, targeting agricultural operations, disaster response, and other industrial sectors.

The concerns raised during the approval process were substantial and specific. Flashes produced during the satellite's repointing maneuvers could temporarily blind pilots and drivers, creating immediate safety hazards. The constant artificial light would disrupt the circadian rhythms of plants, animals, and humans—the biological clocks that govern sleep, reproduction, and countless other functions. Sensitive scientific instruments on research telescopes and star-tracking cameras on lower-altitude satellites could be overwhelmed and damaged by the reflected light. When asked to address these objections, the FCC responded that such concerns fell outside its mandate. The commission stated that the risks related to the satellite's physical effects on human health and the environment were separate from its role in managing radiofrequency spectrum use. In other words, the FCC approved the technology based on radio frequencies while declining to evaluate the broader consequences.

This approval arrives amid a broader explosion of increasingly ambitious space ventures. The FCC recently published a document titled "Spectrum abundance for weird space stuff," acknowledging that American companies are now proposing everything from orbital pharmaceutical manufacturing to private spacecraft, lunar robotic missions, space hotels, artificial meteor showers, and even space burials. The regulatory environment has become a kind of free-for-all, with corporations launching proposals designed more to attract investor attention than to solve genuine problems.

The bottleneck is SpaceX. Nearly 11,000 Starlink satellites already orbit Earth, giving the company effective control over low-Earth orbit. Any new launch must account for SpaceX's operations or risk collision. A near-miss between a Starlink satellite and a Chinese satellite in December 2025 illustrated the danger. Even NASA's Artemis missions required launch windows adjusted to avoid the Starlink constellation. The 1967 Outer Space Treaty, signed by more than 100 countries including the United States, China, and Russia, explicitly states that outer space cannot be claimed through occupation or use. Whether SpaceX's dominance violates this principle is now being tested in practice.

The problem is compounding rapidly. In February, SpaceX filed with the FCC to launch one million additional satellites for artificial intelligence data centers—forty times more satellites than have ever been launched in human history, using technology that has never been tested in space. The FCC approved the filing at remarkable speed, giving scientists worldwide just thirty days to model the effects with incomplete information about the satellites' mass, size, composition, and orbital distribution. Four other companies have since filed copycat proposals for tens of thousands of AI data center satellites each. SpaceX has also proposed another 100,000 satellites to interface with its million-satellite constellation.

The regulatory structure itself is inadequate for the task. The FCC was originally created to oversee radio broadcasts. It now finds itself evaluating orbital safety, atmospheric impacts, and collision risks—domains where it may lack the necessary expertise. Moving this evaluation to the Office of Space Commerce would make sense, but recent budget cuts have made that impossible. As a result, the FCC will soon face an avalanche of satellite proposals, including multiple schemes to harvest solar energy in space and beam it to Earth through high-energy beams that could alter atmospheric chemistry and kill wildlife.

The environmental costs are being obscured by claims of clean energy. Building, launching, maintaining, and eventually burning up tens of thousands of satellites in Earth's atmosphere carries enormous environmental consequences that are rarely factored into the equation. Preliminary research suggests that using the atmosphere as a crematorium for this many satellites will have devastating effects on ozone and other atmospheric chemistry. Space debris removal companies are working to prevent Kessler Syndrome—a runaway chain reaction of collisions—but no one has clearly defined who is responsible when that debris falls back to Earth and causes damage or death. Low-Earth orbit is not infinite. Satellites complete an orbit every ninety minutes, creating enormous collision potential. The satellites and rocket bodies that have already burned up in the atmosphere have measurably altered it. The question now is whether the regulatory system can adapt fast enough to manage the consequences of unfettered growth in orbital activity, or whether the pursuit of profit will outpace the engineering and governance needed to sustain these operations long-term.
