THIS SOUNDS LIKE A REALLY BAD IDEA

"Since SpaceX began launching Starlink satellites in 2019, astronomers have grown increasingly concerned. It's almost impossible now to take a deep-sky image without satellite streaks in the foreground. The megaconstellation numbers nearly 11,000 functioning satellites, and SpaceX launched another 1,730 during the first half of 2026 alone.

Soon, Starlink may be the least of their worries.

Last week, the FCC authorized Reflect Orbital Inc. to launch a huge space mirror named “Eärendil-1.” From an orbit about 625 km high, it will cast a moving, 5-km-wide patch of light onto the Earth about as bright as a full Moon. Later, the company could combine beams from multiple satellites to create much brighter spotlights. Reflect Orbital wants to launch 50,000 more by 2035, selling sunlight-on-demand to solar farms, construction sites and search-and-rescue teams.

If Reflect Orbital's plan is realized, it could be calamitous not only for astronomy but also for the natural world as a whole. Nocturnal animals and night-blooming plants, tuned by evolution to the rhythm of day and night, would suddenly find their darkness interrupted by moving pools of redirected sunlight. Small favors? Reflect Orbital says the light will not be bright enough to start fires.

The FCC itself acknowledged some of these concerns, but noted in its order that optical astronomy and the environment lie largely outside its jurisdiction. They can only regulate the project's use of radio signals. For now, no US agency regulates how bright a satellite may shine.

The company's FCC application attracted more than 1,800 public comments, most of them sharply critical. Nevertheless, the launch of Eärendil-1 is now expected before the end of the year."

Solar mirrors in space can be used to change the amount of sunlight that reaches the Earth. The concept was first theorised in 1923 by physicist Hermann Oberth and later developed in the 1980s by other scientists. Space mirrors can be used to increase or decrease the amount of solar energy that reaches a specific point of the earth for various purposes.

There have been several proposed implementations of the space mirror concept but none have been implemented thus far other than the Znamya experiment by Russia, due to logistical concerns and challenges of deployment. Znamya successfully tested reflecting more sunlight to Earth.
