The U.S. Federal Communications Commission can single-handedly green-light massive spaceflight projects that could completely change the view of the night sky for the entire world, raising urgent questions about the limits of national regulatory power. Space law experts say there is very little other nations and the international community can do to thwart these decisions if the FCC grants operational licenses. On July 10, the agency approved an application by California-based Reflect Orbital to launch a 59-by-59-foot space mirror to test reflecting sunlight onto Earth-based solar farms after dusk.
Regulatory Gaps and the Limits of International Space Law
The decision to approve Reflect Orbital’s test has sparked immediate outcry among astronomers and environmentalists concerned about global light pollution levels. Opponents view the approval, issued despite hundreds of objections, as an indication that the FCC might eventually green-light an entire constellation of 50,000 sun-reflecting mirrors. Alongside these mirror plans, companies including SpaceX, Blue Origin, and Starcloud await decisions on deploying massive fleets of orbiting data centers and internet-beaming satellites. If realized, these projects will alter the night sky beyond recognition.
The framework governing outer space relies heavily on the United Nations’ Outer Space Treaty, conceived in the late 1960s. According to that document, approvals for satellite projects fall squarely to the nation in which the satellites are registered. “The U.N. Treaty for Uses of Outer Space very well specifies that how many satellites are shot into space and how they are registered is a prerogative of the country in which they are registered,” an anonymous source familiar with United Nations Office of Outer Space Affairs (UNOOSA) operations told Space.com.
Did you know? The Outer Space Treaty states in Article I that space exploration “shall be carried out for the benefit and in the interests of all countries,” though the treaty lacks enforcement mechanisms for disagreements.
Liability Limits and the Challenge of Optical Interference
While launching states are responsible for physical damage caused by their registered satellites, liability provisions do not easily extend to environmental or optical disruptions. Ruskin Hartley, the CEO and Executive Director of advocacy group DarkSky International, explained to Space.com that the treaty’s liability scope covers physical collisions or spacecraft crashing down to Earth. “It hasn’t been tested at all but most people don’t think this damage extends to optical interference,” Hartley said. “It would have to be physical damage. If a satellite reflects sunlight down and damages someone’s observatory, that probably doesn’t count as damage under the Outer Space Treaty.”
Efforts by international bodies to establish oversight face severe bureaucratic hurdles. The anonymous UNOOSA source noted that UN institutions operate slowly and require unanimous consensus to pass measures. “These UN institutions were all started in the last century and are very slow,” the source stated. “They require unanimous consensus to pass anything and that obviously hardly ever happens. So nothing gets passed. By the time UN COPUOS and UNOOSA are done discussing anything, SpaceX will have launched another thousands satellites.”
Global Pushback and Unilateral Decisions by the U.S.
In response to these regulatory gaps, the European state of Slovakia, in cooperation with the International Astronomical Union (IAU), submitted a paper to the UN Committee on the Peaceful Uses of Outer Space (COPUOS) in June. The paper calls for a general prohibition on space mirrors or the development of strong oversight mechanisms. Aaron Boley, an astronomer at the University of British Columbia involved with the initiative, acknowledged the slow pace of these diplomatic efforts. “There is indeed a major challenge right now with single states being able to create large changes to the sky and the orbital environment,” Boley told Space.com.
Frank, the U.S. frequently advances its agenda independently of international consensus. Frank pointed to recent FCC approvals for direct-to-cell communication systems utilizing radio frequency spectrums unauthorized by the International Communications Union. “This is not the first time the FCC has started down the route of unilateral decisions,” Frank told Space.com, noting that the agency often argues such moves give domestic industry a competitive edge. Individual nations could theoretically ban space mirrors from beaming light onto their territory under threat of fines, Frank added, but this would not prevent the overall light pollution generated as satellites orbit the planet.
Environmental Exemptions and Future Legal Challenges
DarkSky International previously challenged the FCC at the District Court of Columbia over licenses granted to SpaceX without an environmental review, though the court rejected the arguments. Hartley indicated that the advocacy group would consider filing another lawsuit if the FCC green-lights the full Reflect Orbital constellation or SpaceX’s proposed orbiting data centers. The satellite industry remains exempt from the U.S. National Environmental Policy Act—an exclusion established in the 1980s when launches were rare.
“It’s a regulatory failure,” Hartley said. “The ultimate fix is probably a legislative fix, or an administration that directs them to act differently. But this administration is not going to do that.” A recent study by European Southern Observatory astronomers estimated that planned constellations could increase night sky brightness by up to 300 percent, potentially ending traditional astronomy.
Beyond light pollution, experts warn of wider ecological impacts. Hartley highlighted that launch and deorbit phases risk damaging the ozone layer, altering atmospheric thermal balances, and releasing greenhouse gases that offset the purported efficiency of space-based data processing. “This is more than just a niche issue for astronomers,” Hartley said. “This is an issue that’s going to affect the quality of life for everybody on Earth.”
