The US Federal Communications Commission (FCC) has authorized Reflect Orbital to launch Eärendil-1, a prototype satellite equipped with an 18-meter reflective film designed to redirect sunlight to Earth at night. Source: The Verge The company plans to eventually deploy up to 50,000 such satellites by 2035, offering "on-demand" sunlight for solar energy, agriculture, search and rescue, and construction.

The proposal has drawn sharp criticism from astronomers and environmental groups. The American Astronomical Society (AAS) warned that the satellite "would be intentionally reflecting sunlight on Earth and is designed to be as bright as possible," potentially causing eye damage to observers and blinding pilots and drivers. Source: Engadget The European Southern Observatory (ESO) stated that the full constellation would increase sky brightness at its facilities by a factor of three to four, calling it "an existential threat" to optical astronomy.

Reflect Orbital claims it will implement safeguards, such as avoiding reflections near observatories and turning satellites off by default.

“Reflect Orbital has been given the green light to launch its first space mirror that aims to redirect sunlight down to Earth at night.”
“For optical astronomy, this is an existential threat, and we hope that the regulators will share that view.”
“AAS opposes the granting of a license to Reflect Orbital, because this application is fundamentally different from those for telecommunications satellites.”
“The orbital space mirror's potential for disrupting astronomy is even greater than the threat posed by Elon Musk’s planned million-satellite Orbital Data Center.”
“Our satellites’ default will be 'off' and we will retain full control to turn them off, dim the light and relocate the spot at any stage.”
