The U.S. Federal Communications Commission (FCC) authorized Santa Monica-based startup Reflect Orbital to launch an experimental satellite, Eärendil-1, designed to reflect sunlight to specific locations on Earth at night. While the company intends to test the technology for solar energy and emergency services, the project has sparked intense opposition from the global scientific community.
FCC Approval and the Eärendil-1 Mission
On July 9, the Federal Communications Commission granted authorization for Reflect Orbital to deploy a test satellite at an altitude of approximately 625 kilometers. The experimental craft, named Eärendil-1, carries an 18-meter reflector intended to illuminate areas five to six kilometers in diameter. The company, which has raised $28 million to date, describes the mission as a crucial step toward validating its technology, which aims to provide on-demand
sunlight.
Reflect Orbital has argued that the capability to direct sunlight could support search-and-rescue operations, assist critical infrastructure during emergencies, and extend the productive hours of solar energy facilities. Following the ruling, the company stated on social media that the decision was hugely validating for our company and reflects America’s leadership in testing innovative space technology.
However, the current FCC authorization is strictly limited to this single experimental satellite; any future commercial constellation would require separate, rigorous regulatory approval.
Astronomical Opposition and the Risk of Sky Pollution
The proposal has drawn significant criticism from major scientific bodies, including the Royal Astronomical Society (RAS), the International Astronomical Union, and the European Southern Observatory. Opponents express concern that even a limited test could set a precedent for a future constellation of up to 50,000 satellites by 2035, which they argue would fundamentally alter the night sky.
“For optical astronomy, this is an existential threat, and we hope that the regulators will share that view.”
Betty Kioko, institutional affairs officer for the European Southern Observatory
Furthermore, researchers at the RAS have calculated that the light from these satellites could be four times brighter than the full Moon, potentially making the night sky three to four times brighter than its natural state.
Technical Feasibility and Economic Viability
Beyond the environmental concerns, some researchers question the efficiency of the proposed system. Monash University research suggests that the amount of sunlight delivered by a single mirror is minimal. Estimates indicate that each 180-foot production mirror would deliver only 1/140,000th of midday sunlight intensity, meaning thousands of satellites would need to focus on a single target to generate any meaningful power. Reflect Orbital has indicated it would charge approximately $5,000 per hour for its services, a price point that critics argue may not be economically competitive compared to existing battery storage and grid-scale solutions.
| Metric | Proposed Capability |
|---|---|
| Satellite Altitude | 625 kilometers |
| Target Area | 5–6 kilometers in diameter |
| Estimated Cost | $5,000 per hour |
| Long-term Goal | 50,000 satellites by 2035 |
Regulatory Gaps in Orbital Oversight
A central frustration among critics is the current scope of the FCC’s regulatory mandate. According to Gadgetreview, the agency is primarily focused on radio interference and satellite disposal, leaving a gap regarding the environmental and ecological impacts of orbital infrastructure.
