A large replicate to create “sunlight on demand” used to be simply authorized via the US Federal Communications Fee (FCC), regardless of opposition from astronomers and the general public, and actual protection considerations.
The FCC authorized the corporate Mirror Orbital to check one satellite tv for pc, named Earendil-1, as a method of reflecting the solar’s rays again to Earth for added solar power and wide-area lighting fixtures. The sunshine is anticipated to hide a space about 5 kilometres huge, and would require repointing each 4 mins.
And that is just the beginning. Mirror Orbital plans to have greater than 50,000 satellites in motion via 2035, which they declare will probably be used throughout agricultural, emergency reaction and different commercial sectors.
There are lots of issues of this proposal, together with affects those satellites could have on human well being and protection, in addition to on astronomy and the low-Earth atmosphere.
Flashes all over replicate repointing may disrupt pilots and drivers. The sunshine may additionally disrupt circadian rhythms of crops, animals and people. Delicate detectors in analysis telescopes, in addition to star-tracking cameras on decrease altitude satellites, might be overloaded and fried.
The FCC mentioned 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.”
Mirror orbital manufacturers itself as, ‘the sunlight company.’

‘Weird space stuff’
Satellite tv for pc proposals for “emergent space activities” in low-Earth orbit are turning into an increasing number of outlandish. The proposals have grow to be so bizarre, in truth, that the FCC just lately revealed a file known as “Spectrum Abundance for Weird Space Stuff.”
“Once the province of science fiction,” this file states, “American companies are now upgrading, relocating and servicing satellites; manufacturing pharmaceuticals in space; building private inhabitable spacecraft; and conducting private robotic missions to the surface of the Moon.”
Thousands and thousands of orbital AI knowledge centres also are deliberate. Companies appear to be scrambling to release the rest that would possibly convince buyers throw cash at them: area promoting, motels for billionaires, synthetic meteor showers, area burials for cremated stays, solar-powered infrared beams to energy knowledge centres and numerous orbital missiles.
The word “weird space stuff” is refreshingly honest. So, how did we get right here?
SpaceX controls orbit
There are just about 11,000 SpaceX Starlink satellites these days in orbit above our heads. Somebody who desires to release into low-Earth orbit wishes to scrupulously imagine SpaceX operations, or immediately co-ordinate with them.
Differently they chance collisions, just like the near-miss between a Starlink and Chinese language satellite tv for pc in December 2025.
Even the Artemis I release in 2022 and Artemis II release in 2026 had small “cutout” home windows of their release timing to keep away from satellites, together with the ones belonging to Starlink.
Co-ordination is excellent. Forcing it as a result of one company has successfully occupied low-Earth orbit isn’t. Certainly, the 1967 Outer House Treaty, which used to be signed via greater than 100 nations together with the US, China and Russia, states that, “outer space is not subject to national appropriation by claim of sovereignty, by means of use or occupation.”
Whether or not SpaceX’s in depth use of Earth orbits violates this theory is now being examined in actual time.
Copycat megaconstellations
In February, SpaceX filed with the FCC for 1,000,000 extra satellites, for “AI data centers.”
A million. This is 40 occasions as many satellites as have ever been introduced — for a unmarried megaconstellation consisting of utterly untested generation that won’t even paintings in area.

Now not handiest did the FCC settle for SpaceX’s submitting, however they did so at ludicrous velocity. Scientists international then had simply 30 days to type the consequences with woefully incomplete knowledge on plenty, sizes, compositions and orbital distributions.
On the time of writing, 4 different copycat AI knowledge centre proposals were filed via rival firms, for tens of hundreds of satellites every. And SpaceX simply proposed any other 100,000 satellites to interface with the million AI knowledge centres that it already requested for.
Solar power from area
The U.S. Federal Communications Fee used to be at the beginning set as much as keep an eye on radio declares. However it’s now being requested to guage many non-radio results, together with orbital protection, which it won’t have the specified experience for. It could make sense to transport a few of this analysis to the U.S. Place of business of House Trade. Then again, fresh price range cuts make that infeasible.
Because of this, the FCC will quickly be requested to pass judgement on a frightening vary of satellite tv for pc proposals. They come with a cluster of proposals to assemble solar power from area.
One thought is to ship solar energy all the way down to earth thru prime power beams. Those may trade atmospheric chemistry and kill birds and different flora and fauna that stray into the beam.
They’d additionally require no-fly zones round receiving stations for airplanes and in addition satellites on decrease altitude orbits (such because the orbits SpaceX simply asked for 100,000 extra Starlink satellites).
Environmental prices
Whilst many of those initiatives declare to unravel environmental issues via growing blank power or taking pictures it in area, they serve as as a type of greenwashing.
The solar power generated is handiest blank for those who forget about the environmental prices of creating, launching, keeping up and burning satellites up in Earth’s surroundings. The day by day operations of a majority of these proposed methods could have large environmental penalties.
The objective of many ‘weird’ area initiatives is beaming the solar to Earth at night time to energy photo voltaic farms.

There are firms that experience examined plans for eliminating area particles from orbit. That is useful for fending off Kessler Syndrome — a runaway chain response of collisions. However the place will the particles move as soon as got rid of from orbit?
It’s going to fall into Earth’s surroundings, the place it is going to deposit steel and most likely have an effect on Earth’s floor. It’s unclear who’s answerable for any ensuing harm or deaths.
For all humankind
The vast majority of satellites in orbit lately are American, and the principle federal company regulating satellites isn’t arrange to do this neatly. We at the moment are seeing the results.
Whilst outer area is successfully limitless, low-Earth orbit maximum indisputably isn’t. Satellites orbit the Earth round as soon as each 90 mins. This implies the collision doable between two items in orbit is huge.
The numerous satellites and rocket our bodies that experience burned up in Earth’s surroundings over the previous couple of years have already measurably altered it. Initial research display that the use of Earth’s surroundings as a crematorium for tens of hundreds of satellites could have devastating results on ozone and different atmospheric chemistry.
Astronomy may be below risk from one of the most “weirder” concepts like area mirrors, photo voltaic sails and diffuse sky brightening from orbital particles.
An innovation problem
We aren’t right here to argue in opposition to satellites. Certainly, they supply quite a lot of recommended services and products to science and society. However every satellite tv for pc comes with a value that should be taken into consideration.
In the long run, that is an innovation problem. Unfettered expansion and exploitation of any atmosphere comes with severe penalties, together with to the long-term sustainability of the operations that rely on that atmosphere.
Doing extra with much less is the engineering problem that must be met if we need to proceed to make use of satellites in orbit.
