“Despite a flood of objections, the FCC has approved a startup's plan to launch a controversial satellite that’ll use a giant mirror to reflect sunlight to Earth after dark.
On Thursday, the FCC granted California-based Reflect Orbital permission to launch and operate the satellite in low-Earth orbit using the requested radio spectrum. The reflected light from the satellite is supposed to span an area about 3 miles wide on the ground.
The approval is only for one satellite, dubbed Earendil-1, which is meant to test Reflect Orbital’s technology for shining sunlight back to Earth. The satellite will boast a steerable thin-film reflector measuring about 60 feet by 60 feet, with the goal of powering solar farms at night or illuminating disaster-struck areas after dark to help rescue teams.
Reflect Orbital envisions operating over 50,000 satellites by 2035, effectively surrounding the Earth with a fleet of mirrors.“

“A proposed constellation of satellites has astronomers very worried. Unlike satellites that reflect sunlight and produce light pollution as an unfortunate byproduct, the ones by US startup Reflect Orbital would produce light pollution by design.
The company promises to produce “sunlight on demand” with mirrors that beam sunlight down to Earth so solar farms can operate after sunset.
It plans to start with an 18-metre test satellite named Earendil-1 which the company has applied to launch in 2026. It would eventually be followed by about 4,000 satellites in orbit by 2030, according to the latest reports.
So how bad would the light pollution be? And perhaps more importantly, can Reflect Orbital’s satellites even work as advertised?”
