FCC approves space mirror test to light night sky despite outcry
The Federal Communications Commission approved Reflect Orbital's Eärendil-1 test satellite on July 9, 2026, clearing a California startup to launch a steerable 60-foot space mirror that will reflect sunlight onto Earth after dark—despite heavy opposition from astronomers, wildlife experts, and thousands of public commenters. The FCC approves space mirror licensing for radio spectrum use only, not the visual or environmental impacts critics warn could disrupt stargazing, pilots, and natural light cycles.
Reflect Orbital, based in Hawthorne, California, plans to deploy the single demonstration craft later this year into low Earth orbit at roughly 625 kilometers. The 142-kilogram satellite will unfurl an 18-by-18-meter thin-film reflector and aim moving beams of sunlight at targeted ground areas for several minutes at a time.
Key Takeaways
- The FCC granted a two-year license for one test satellite, Eärendil-1—not Reflect Orbital's proposed fleet of up to 50,000 mirrors.
- Reflected light is expected to cover an area about three to five miles wide, requiring the mirror to repoint roughly every four minutes.
- Astronomers and environmental groups objected, but the FCC said optical and ecological impacts fall outside its radio-spectrum authority.
- Reflect Orbital says the technology could extend solar farm output, aid emergency crews, and provide targeted nighttime lighting.
- The company must coordinate with NASA and the National Science Foundation to limit interference with optical astronomy.
What Did the FCC Actually Approve?
On July 9, the commission issued order DA 26-706 authorizing Reflect Orbital to launch and operate Eärendil-1 using requested radio frequencies. The approval covers a limited two-year demonstration in a near-polar orbit between 600 and 650 kilometers in altitude.
The FCC emphasized it was green-lighting only a single innovation test, not the company's long-term vision of surrounding Earth with tens of thousands of reflective satellites by 2035. Reflect Orbital has said SpaceX will carry its first demonstration satellites aboard Falcon 9 rockets.
Why Are Astronomers and Scientists So Upset?
Opposition flooded in from the American Astronomical Society, wildlife specialists, and members of the public—PCMag reported roughly 800 comments, many of them negative. The AAS told the FCC the project "cannot be considered to serve the public interest" and could waste taxpayer dollars by damaging federally funded observatories.
Critics warn the mirror could add skyglow, blind sensitive telescope detectors, distract airplane pilots during repointing flashes, and disrupt circadian rhythms in people, plants, and animals. The European Southern Observatory has cautioned that Reflect Orbital's satellites could rank among the brightest artificial objects ever placed in orbit.
In its order, the FCC concluded that concerns about optical astronomy and reflected sunlight were beyond its statutory remit. The agency noted U.S. courts have blocked it from applying a generalized public-interest standard beyond communications regulation.
What Happens Next for 'Sunlight on Demand'?
Reflect Orbital calls itself "The Sunlight Company" and pitches Eärendil-1 as the first step toward beaming sunlight to solar farms after sunset, lighting disaster zones for rescue teams, and even illuminating city streets. The startup says the mission will yield real-world data on mirror control, community engagement, and future market design.
Whether a single test mirror becomes a constellation of 50,000 is far from settled. The FCC's approval does not authorize that fleet, and regulators may soon face more exotic proposals as low Earth orbit grows crowded with data centers, solar collectors, and other unconventional payloads—a trend that sits somewhere between breakthrough engineering and the kind of head-scratching stories we cover in Bizarre News & Florida Man.
