Reflect Orbital received Federal Communications Commission authorization to test a satellite designed to reflect sunlight back to Earth after dark [1].
The California-based startup aims to enable solar power generation at night, creating a new market for selling renewable energy after sunset [1, 2]. This technology could potentially address the intermittent nature of solar power by providing a continuous light source for ground-based panels.
The test satellite, named Eärendil-1, is slated for launch later in 2026 [2]. The company intends to use a specialized mirror in orbit to bounce sunlight to specific locations on the ground, bypassing the natural shadow of the Earth [1].
This project seeks to bridge the gap in renewable energy production that occurs when the sun is not visible. By redirecting light during the night, the company hopes to stabilize the delivery of solar energy, and reduce the reliance on battery storage or fossil-fuel backups [1, 2].
The FCC approval allows the company to move forward with the technical testing of the satellite's communication and operational systems. The launch will be conducted from the U.S. as the company prepares for its initial orbital trial [1, 2].
Experts remain divided on the viability and implications of the project. While the prospect of 24-hour solar power is promising for energy grids, the physical act of reflecting sunlight into the night sky may raise questions regarding light pollution and astronomical observations [2].
“Reflect Orbital received Federal Communications Commission authorization to test a satellite designed to reflect sunlight back to Earth after dark.”
If successful, Reflect Orbital's technology would transform solar energy from a diurnal resource into a constant power source. However, the project faces significant hurdles beyond regulatory approval, including the precision required to target light beams and the potential backlash from the global scientific community over the disruption of the natural night sky.
