The US Federal Communications Commission (FCC) has authorized California-based startup Reflect Orbital to build, launch, and operate a prototype mirror satellite in low Earth orbit. Named Eärendil-1 after a character from J.R.R. Tolkien's works, the satellite is designed to redirect sunlight to specific areas on Earth after dark using an 18-meter reflective surface. The company plans to eventually operate a constellation of 50,000 such satellites by 2035, offering "on-demand" sunlight for applications including solar energy, search-and-rescue missions, and emergency response. The authorization covers only a single experimental satellite, and any future commercial constellation would require new regulatory approvals. The decision came despite opposition from astronomers and environmental groups who warned about increased light pollution and potential harm to wildlife and aviation safety. Nearly 2,000 public comments opposing the project were filed with the FCC during the regulatory review process.
What’s verified
The US Federal Communications Commission (FCC) authorized Reflect Orbital to launch a mirror satellite named Eärendil-1.
The satellite is equipped with an 18-meter reflective surface designed to redirect sunlight to Earth at night.
Reflect Orbital plans to deploy a constellation of 50,000 satellites by 2035.
The illuminated area on the ground is reported to be approximately 5 kilometers (3 miles) in diameter.
Potential applications include solar energy, search-and-rescue operations, and emergency response.
Astronomers and organizations including the American Astronomical Society, DarkSky International, and the Royal Astronomical Society voiced opposition.
European Southern Observatory official Betty Kioko called the technology "an existential threat" to optical astronomy.
The FCC received nearly 2,000 public comments opposing the proposal.
The authorization covers only a single experimental satellite, not a commercial constellation.
Not yet confirmed
