The United States has authorized Reflect Orbital to deploy and operate Earendil-1, a demonstration satellite built to redirect sunlight onto Earth after dark. The craft is expected to unfold a steerable mirror about 59 feet on each side, then aim a roughly 3.1-mile-wide patch of light at selected locations from low-Earth orbit<\/a>.<\/p>\n\n\n\n

The approval covers one test satellite, not the California startup\u2019s proposed constellation of more than 50,000 spacecraft<\/a>. Still, the decision carries a much larger message because the FCC said light pollution, optical astronomy, and most non-radio environmental effects fall outside its regulatory authority, a conclusion that opponents are now asking the full Commission to reverse.<\/p>\n\n\n\n

What Earendil-1 will do<\/h2>\n\n\n\n

Earendil-1 is authorized to operate at about 388 miles above Earth after entering orbit. Its thin-film reflector will be motorized and steerable, and Reflect Orbital says the first demonstrations are meant to provide moonlight-like illumination for only a few minutes while engineers measure performance and safety.<\/p>\n\n\n\n

The company wants to sell \u201csunlight on demand<\/a>\u201d to solar farms, industrial sites, emergency crews, agriculture, events, and defense customers. Its military link is already real, since Reflect Orbital announced a $1.25 million AFWERX small-business contract in 2025 to study responsive lighting and energy resilience for Air Force operations.<\/p>\n\n\n\n

Why the FCC said yes<\/h2>\n\n\n\n

The FCC\u2019s Space Bureau granted the license on July 9, 2026, finding that a limited test would support American technological leadership and help determine whether the concept is viable.<\/p>\n\n\n\n

The authorization is for radio communications, spacecraft control, data downlinks, and orbital-debris compliance<\/a>, with a two-year license term beginning after Earendil-1 is successfully placed in orbit.<\/p>\n\n\n\n

\"A
Regulatory approval of the Earendil-1 orbital mirror test sparks fierce opposition from astronomers and environmentalists concerned about night sky light pollution.<\/figcaption><\/figure>\n\n\n\n

More than 1,800 people submitted letters, while scientific and environmental groups asked the agency to reject the project or add safeguards. The Bureau nevertheless concluded that the mirror\u2019s optical effects were too far removed from its spectrum authority, and it declined to require a full environmental assessment under federal law.<\/p>\n\n\n\n

Astronomers see a different risk<\/h2>\n\n\n\n

Astronomers argue that a deliberately bright spacecraft is not comparable to an ordinary satellite that happens to reflect sunlight. The American Astronomical Society<\/a> warned that Earendil-1 could saturate sensitive detectors, interrupt federally funded observing programs, and pose eye-safety concerns for people using larger telescopes.<\/p>\n\n\n\n

Reflect Orbital has committed to coordinating with NASA, the National Science Foundation, and the wider astronomy community, including work on exclusion zones near research sites. <\/p>\n\n\n\n

But the FCC declined to impose several requested protections, such as an independent brightness standard, a public pointing schedule, and a roughly 100-mile buffer around registered observatories.<\/p>\n\n\n\n

One test could become 50,000<\/h2>\n\n\n\n

Reflect Orbital\u2019s public roadmap<\/a> grows from two satellites in 2026 to more than 1,000 by 2028, more than 5,000 by 2030, and more than 50,000 by 2035. The company says larger constellations could extend solar<\/a> production after sunset and eventually provide light comparable to workplaces or daylight for longer periods.<\/p>\n\n\n\n

That future network has not been approved, and the FCC said any later application would be judged separately. The concern is the logic behind the first ruling, since critics say a regulator that cannot review the light from one mirror may also struggle to assess the cumulative glow from thousands.<\/p>\n\n\n\n
