ight falls, solar panels stop producing, and emergency crews often turn to fuel-powered generators and floodlights. A California startup now wants to offer another option by redirecting sunlight from orbit to a chosen place on Earth for a few minutes.
On July 9, 2026, the Federal Communications Commission authorized Reflect Orbital to deploy and operate Earendil-1, one experimental satellite carrying a reflector about 59 feet by 59 feet. From an orbit roughly 388 miles above Earth, the spacecraft is intended to create a moonlike patch of light about 3.1 miles wide while testing whether that footprint can be aimed and controlled accurately.

Earendil-1 will not make electricity or store solar energy. Its thin reflective film will act like a giant heliostat in space, turning so it can intercept sunlight while the satellite remains sunlit and redirect that light toward a location that has already entered darkness.
Because it moves quickly through low Earth orbit, a single pass would illuminate a target only briefly. Reflect Orbital says its planned 2026 demonstration is designed to provide around 0.1 lux for up to five minutes, equal to roughly 0.009 foot-candles and comparable to a clear night under a full moon.
The light can be removed from the ground by changing the spacecraft’s orientation. That steering ability is at the heart of the mission, since the test must show that the reflector can unfold, point accurately, hold its footprint, and turn away when service ends.
