Reflect Orbital raises $73.5 million to beam sunlight from space mirrors after dark

Reflect Orbital announced $73.5 million in new funding on November 10, taking its total above $100 million. Existing investors Sequoia Capital, Lux Capital and Starship Ventures took part, along with new investors including Buckley Ventures, Convective Capital, The Uncommon Group and Salesforce Ventures. Its previous round was a Series A in May 2025.

The company is developing satellites with large reflectors intended to redirect sunlight to chosen places on Earth. It names extending solar generation after sunset and lighting search and rescue operations as potential uses. The funding is intended to support initial launches, reflector development and commercial partnerships.

The release also gives production figures. Reflect Orbital says it builds a large reflector quadrant every 3.5 days during production, using material it describes as 28 times thinner than a human hair. It says it builds a satellite containing 12000 parts every two months. These are company production claims, not results from an orbital demonstration.

The company says its demonstration mission has FCC approval and is planned for the second quarter of 2027. The same announcement separately describes an application for a developmental satellite that remains subject to regulatory approval. The release does not establish approval for a commercial constellation.

For makers following ambitious hardware projects, the distinction is between building equipment and demonstrating the service. Reflect Orbital has published a manufacturing cadence and a future test date. Whether those reflectors can deliver useful light and a viable commercial service remains the test ahead.
