Supposedly these things create a spot on earth that's several km wide. This should be great for the planet...
A giant mirror to create “sunlight on demand” was just approved by the United States Federal Communications Commission (FCC), despite opposition from astronomers and the public, and real safety concerns.
The FCC approved the company Reflect Orbital to test one satellite, named Earendil-1, as a means of reflecting the sun’s rays back to Earth for extra solar energy and wide-area lighting. The light is expected to cover an area about five kilometres wide, and will require repointing every four minutes.
And this is just the start. Reflect Orbital plans to have more than 50,000 satellites in action by 2035, which they claim will be used across agricultural, emergency response and other industrial sectors.
There are many problems with this proposal, including impacts these satellites will have on human health and safety, as well as on astronomy and the low-Earth environment.
Flashes during mirror repointing could disrupt pilots and drivers. The light could also disrupt circadian rhythms of plants, animals and humans. Sensitive detectors in research telescopes, as well as star-tracking cameras on lower altitude satellites, could be overloaded and fried.
The FCC said that the “risks of harm raised on the record regarding Reflect Orbital’s solar reflector are unrelated to the Commission’s role in authorizing use of radiofrequency spectrum.”
