TOKYO — The Federal Communications Commission has given its approval for a satellite that will test the ability to reflect sunlight into nighttime regions, a project sharply criticized by astronomers and environmentalists.
The FCC on July 9 formally authorized the launch of Eärendil-1, a satellite developed by Reflect Orbital that will deploy a thin-film reflector 18 meters on a side in low Earth orbit, reflecting sunlight to the ground.
The 142-kilogram spacecraft is scheduled to launch later this year into an orbit 600 to 650 kilometers in altitude, where it will deploy the reflector. The company plans to use the spacecraft to test its ability to direct reflected sunlight to specific areas on Earth for several minutes at a time.
“We’re grateful to the FCC for recognizing the importance of testing novel technologies in space,” Ben Nowack, chief executive of Reflect Orbital, said in a statement. “This license is the first step toward rigorously testing our technology’s efficacy and the safeguards we have developed.”
The company said it has seen strong interest in its technology to provide lighting for activities ranging from construction sites to search-and-rescue efforts. The company also proposes using such satellites to reflect sunlight onto terrestrial solar farms to increase their energy production.
The concept, though, has generated strong criticism from some quarters. Environmentalists have warned that the reflected sunlight from a constellation of such spacecraft — Reflect Orbital has proposed operating thousands of spacecraft — could disrupt the diurnal cycles of plants and animals. Astronomers worry that such spacecraft could interfere with their operations and even be dangerous to instruments mounted on telescopes or to people looking through telescope lenses.
At a June 4 National Academies meeting, Tony Tyson, distinguished research professor at the University of California, Davis, and chief scientist of the Vera C. Rubin Observatory, said the Reflect Orbital plans were “even crazier” than the broadband satellite constellations astronomers have worried about for several years.
He said he was concerned that the thin-film reflectors would not be able to precisely direct sunlight, scattering it instead over a wider area. “Imagine the sky full of moons,” he said.
In a July 1 statement, the European Southern Observatory, or ESO, which operates several major telescopes in Chile, said the full constellation of 50,000 satellites that Reflect Orbital has proposed would increase the background sky brightness at its facilities by a factor of three to four, limiting the ability of telescopes to detect faint objects.
Reflect Orbital’s application to the FCC, submitted nearly a year ago, generated nearly 1,900 comments, mostly critical of the potential impacts of the system. SpaceX’s application to operate up to 1 million orbital data center satellites, which astronomers are also worried about, resulted in nearly 1,500 comments.
“The ball is now in the FCC’s court, and we wait to see the determinations they make on both filings,” said Betty Kioko, ESO institutional affairs officer, in the statement. “For optical astronomy, this is an existential threat, and we hope that the regulators will share that view.”
The FCC, in its order, largely concluded that any impacts of Eärendil-1 on astronomy or the environment were outside its jurisdiction.
“We find that concerns about Eärendil-1’s impacts on optical astronomy fall outside our review and authorization of the space station and are not a basis for denial of or additional conditions on Reflect Orbital’s operations,” the FCC stated. It noted the company has committed to collaborating with NASA and the National Science Foundation to protect optical astronomy and to working with the broader astronomical community on its concerns.
The FCC rejected claims that approving Eärendil-1 would not be in the public interest, concluding that “to the contrary, it is in the public interest to make spectrum available to encourage companies to test new and innovative space activities, as it promotes American innovation and the new services and economic growth that come from that innovation.”
The FCC’s authorization for the satellite came a day after environmental and scientific groups formally petitioned the FCC to perform a detailed environmental review, known as a programmatic environmental assessment, for applications of orbital data center constellations.

Executive Summary
The Federal Communications Commission authorized the launch of Eärendil-1, a satellite developed by Reflect Orbital, on July 9th to test reflecting sunlight into nighttime regions. This involves deploying a thin-film reflector 18 meters on a side in low Earth orbit to direct sunlight to the ground for several minutes. The company intends to use this technology for applications like powering construction sites or increasing energy production via terrestrial solar farms.
The project faces significant opposition from astronomers and environmentalists who raise concerns about potential disruption. Environmentalists warn that the reflected light from a proposed constellation of thousands of such satellites could affect the diurnal cycles of plants and animals. Astronomers are concerned that these spacecraft might interfere with telescope operations or pose risks to instruments and observers. Furthermore, the European Southern Observatory stated that a full constellation of 50,000 satellites proposed by Reflect Orbital would increase background sky brightness at their facilities by a factor of three to four, limiting detection capabilities.
The FCC concluded that impacts on optical astronomy and the environment were outside its jurisdiction, asserting that authorizing the launch promotes innovation and economic growth. The authorization followed public petitions for environmental review regarding orbital data center constellations.
Full Take
The narrative presents a direct tension between technological innovation and established scientific/environmental boundaries, framed by regulatory decision-making. The core dynamic involves a private entity seeking approval for novel space technology, positioning its goals (energy generation, terrestrial applications) against public concerns regarding indirect externalities (astronomy, ecology).
A significant pattern emerges in how external critiques are managed: the application generated substantial public comments (1,900 for Reflect Orbital, 1,500 for SpaceX), yet the final regulatory determination focused narrowly on jurisdictional limits rather than mitigating the substance of the scientific and environmental warnings. This suggests a systemic tendency to categorize complex externalities as outside the scope of immediate regulatory oversight when pursuing technological advancement deemed economically beneficial by the authorizing body.
The divergence in reactions highlights a tension between perceived future utility—innovation, economic growth—and present-day risk management. The dismissal of astronomical concerns as being "outside our jurisdiction" demonstrates a specific prioritization mechanism where broad societal innovation is valued over potentially existential or long-term observational risks associated with space utilization. This pattern suggests that the locus of acceptable risk in space technology may be defined by current administrative boundaries rather than a comprehensive assessment of systemic impact, leaving crucial, long-term concerns—like altering celestial observation—unaddressed within the authorization process itself.
What criteria were applied when determining that optical astronomy risks fell outside the FCC's review? If the pursuit of innovation is deemed in the public interest, what mechanism exists to ensure that future regulatory frameworks incorporate the precautionary principle concerning large-scale orbital infrastructure affecting shared cosmic observation? Furthermore, how does the weighting between immediate economic incentives and potential long-term environmental/astronomical stability shift when these two objectives are framed as non-conflicting priorities for a governing body?
