The U.S. Federal Communications Commission's (FCC) recent approval of a giant space mirror to test 'sunlight on demand' has sparked a heated debate. While the idea of harnessing solar energy is appealing, the potential consequences are far-reaching and complex. This article delves into the implications of this decision, exploring the technical, environmental, and ethical considerations that have been overlooked. Personally, I think the FCC's role in evaluating non-radio effects is becoming increasingly challenging, and it's time to reevaluate its approach. The FCC's decision to approve the space mirror, despite opposition from astronomers and the public, raises a deeper question: How can we balance the benefits of space exploration with the potential risks and ethical implications? The proposal to test one satellite, Earendil-1, as a means of reflecting the sun's rays back to Earth for extra solar energy and wide-area lighting is an ambitious one. However, the potential impacts on human health, safety, and the environment are significant. Flashes during mirror repointing could disrupt pilots and drivers, while the light could disrupt circadian rhythms of plants, animals, and humans. Sensitive detectors in research telescopes and star-tracking cameras on lower altitude satellites could be overloaded and fried. The FCC's statement that the risks of harm are unrelated to its role in authorizing use of radiofrequency spectrum is concerning. The FCC's recent publication of a document called 'Spectrum Abundance for Weird Space Stuff' highlights the increasing outlandishness of satellite proposals in low-Earth orbit. The phrase 'weird space stuff' is refreshingly truthful, and it's time to address the implications of these proposals. The presence of nearly 11,000 SpaceX Starlink satellites in orbit has created a complex situation. Any company launching into low-Earth orbit must carefully consider SpaceX operations or coordinate directly with them to avoid collisions. The 1967 Outer Space Treaty, signed by over 100 countries, states that outer space is not subject to national appropriation by claim of sovereignty, use, or occupation. SpaceX's extensive use of Earth orbits may be violating this principle, and it's a real-time test of this treaty. The proposal to launch one million more satellites for AI data centers by SpaceX is concerning. The FCC's acceptance of this filing at such a rapid pace and with incomplete information on masses, sizes, compositions, and orbital distributions is problematic. The potential environmental costs of these projects, including the construction, launch, maintenance, and burning of satellites in Earth's atmosphere, are significant. The solar energy generated is only clean if we ignore these costs. The removal of space debris from orbit is a helpful solution to avoid Kessler Syndrome, but where will the debris go once removed? It will fall into Earth's atmosphere, where it will deposit metal and possibly impact Earth's surface. The majority of satellites in orbit today are American, and the main federal agency regulating satellites is not set up to do it well. The consequences are already being felt, with measurable alterations to Earth's atmosphere and potential impacts on ozone and other atmospheric chemistry. The innovation challenge lies in doing more with less. Unfettered growth and exploitation of any environment come with serious consequences, and it's time to reevaluate our approach to space exploration and satellite technology.
