The United States Federal Communications Commission (FCC) has granted approval to Reflect Orbital to proceed with testing its innovative Earendil-1 satellite. This spacecraft features a substantial mirror engineered to redirect sunlight towards the nighttime side of Earth. The primary objective of the startup is to augment energy supply to solar power facilities and illuminate extensive regions up to 5 kilometers in width. By the year 2035, the company intends to deploy a constellation comprising 50,000 such orbital reflectors.
Notwithstanding the potential advantages for agriculture and emergency services, the initiative has elicited grave concerns within the community. The reflections from the mirrors, which are reoriented every four minutes, possess the capacity to blind drivers and airline pilots. Artificial illumination during nighttime poses a significant threat to the circadian rhythms of both humans and animals. Furthermore, the repercussions for astronomy are profoundly detrimental: highly sensitive telescope instrumentation faces the risk of becoming entirely inoperative due to light overload. The Federal Communications Commission (FCC) has explicitly dissociated itself from the environmental hazards, emphasizing that its jurisdiction is confined solely to the allocation of the radio frequency spectrum.
The Era of “Strange Space Things”
Current proposals for the commercial utilization of low Earth orbit (LEO) are becoming progressively more extravagant. The phrase “spectrum surplus for unconventional space activities” has already been documented in official Federal Communications Commission (FCC) documents. Presently, firms are presenting investors with opportunities ranging from space tourism and orbital advertising to extraterrestrial burials, as well as the establishment of AI-powered data centers directly in space.
SpaceX continues to be the dominant entity in the orbital domain, having launched approximately 11,000 Starlink satellites into orbit. As a result of this extensive presence, all other missions — including NASA’s Artemis I and Artemis II government initiatives — must coordinate their trajectories with the private company to prevent space collisions. Critics argue that this de facto occupation of space constitutes a violation of the 1967 Outer Space Treaty, which explicitly forbids national or corporate appropriation of outer space.
A million artificial intelligence satellites
The ambitions of the private sector continue to expand at a rapid pace. SpaceX has formally submitted an application to deploy an additional one million satellites into orbit to facilitate AI space servers, along with 100,000 supplementary communications satellites. This quantity exceeds by a factor of 40 the total number of objects launched by humanity throughout the entire history of the space era. Despite the experimental status of the technology, the Federal Communications Commission (FCC) granted approval for the application in an unprecedentedly brief period, affording the global scientific community only one month to evaluate the potential risks. Concurrently, SpaceX’s competitors have submitted four additional proposals for similar large-scale projects.
U.S. Regulatory agencies in the United States are increasingly unable to manage the extensive volume of applications and conduct thorough analyses. The Federal Communications Commission (FCC), originally founded to oversee broadcasting, does not possess sufficient expertise to evaluate the physical safety of orbits. Additionally, the budget constraints faced by the U.S. Space Commerce Administration hinder its capacity to assume these responsibilities.
The clandestine environmental risks associated with ‘green” technologies
Engineering initiatives that entail the collection of solar energy in orbit and its subsequent transmission to Earth via highly directional microwave or laser beams pose significant concerns. These energy beams have the potential to locally modify the chemical composition of the atmosphere and pose a threat to avian life, in addition to necessitating the establishment of extensive no-fly zones for civilian aviation.
Most space startups present themselves as environmentally sustainable solutions; however, experts often regard this as the common practice of “greenwashing.” The manufacturing of launch vehicles, the frequency of launches, and the subsequent incineration of numerous decommissioned satellites within the dense atmospheric layers result in a significant environmental impact. Even advanced space debris removal technologies merely relocate the issue, as removed metal structures burn up in the atmosphere, releasing microparticles of aluminum oxide that contribute to ozone layer depletion. Low Earth orbit is a limited resource; therefore, the unregulated exploitation of space necessitates an immediate revision of engineering strategies—humanity must adopt more efficient approaches by utilizing fewer spacecraft.
