I think we should wait to see how the first satellite data centre works out. It seems fairly unlikely that it could be practical. It seems kind of nuts...
>Reflect Orbital, a US start-up, aims to launch a constellation of very large mirror-like satellites to provide sunlight at night, with reflected beams that span at least five kilometres on Earth's surface.
Straight up nuts with no practical value, even if it did work out.
I strongly suspect that what'll happen is SpaceX does launch satellites with onboard GPUs, so the SpaceX hypemen can go "the skeptics said it couldn't be done!" and take off before the actual, more crucial question of "does it make _financial_ sense?" is answered in the extreme negative
Are they worth the cost/tradeoffs? I don’t know. But there is practical value to lighting up the night.
No. Lighting up the night is an abomination. Reflect Orbital can go fuck themselves.
Hell NO!!
Ubiquitous on-the-ground lighting is already disrupting plant, animal, and insect life cycles.
Adding a blanketing sun reflector illuminating five-plus square kilometers at a time will obliterate critical signals to everything living there, and won't do any good for the humans.
And nevrermind the astronomy.
It is an abomination and nothing but a scheme by amoral people to separate other fools from their money.
More regulations would just have the result of cementing a monopoly for Spacex.
I'm still checking the maths on how bright a million satellites in a terminator-following SSO would be. I'm getting very big numbers. But then, the (vague and aspirational) suggestions I'm seeing right now for SpaceX are in the 120 kW range, which is huge, and lining up a million of those is enough for a contiguous ring just under 10 meters wide (how much under is "just under" depends both on how efficient the PV is and how high in LEO you go).
Regardless of if they're all in one orbit or spread over in multiple orbits at different shells that are all terminator-following SSO, from the ground you're getting a train of things with somewhat higher brightness than the ISS, with a fairly small apparent separation that (I tentatively think) becomes less than your eyes can resolve at at least one point in the sky (if there's say 50 shells, where those 50 get close to crossing).
But stuff like mitigating the constant threat of big enough objects showing up on a collision course with earth should not be paused until those eye-catchers fall out of the sky. If there is something coming at us that can wipe out more than the stock price of one particularly space-enthusiastic company, we should like to know within a time period appropriate for our current planetary defense capabilities. Which will surely improve, over time - so maybe we can pollute the sky, later.
I don't really think this is a serious risk. This is a once-in-a-million-years kind of event.
Also, asteroid detection is not seriously affected by satellites. We can easily tell the difference between a moving satellite and a moving asteroid because of their speed.
Not to mention that’s not how it works. We regret burning so much fossil fuel but those who make huge profits from it prevent as much change as they can.
You can bet Amazon and SpaceX will do the same no matter how the rest of us regrets it
Do we put up long-distance power lines and wind farms even though they ruin the views? Do you tear down a forest to put up farmlands and suburbs? Do you build a dam to provide water for irrigation, even though it kills the fish and floods a valley?
Satellites are actually easier than most of those tradeoffs, because nothing lives in space and there's no nature to destroy. It only affects us.
The purpose of most of these satellites is internet access where we already have less limited possibilities with less maintenance costs like constant replacement
And asteroids are an extremely rare threat in the first place. It's literally a once-in-a-million-years kind of event.
City killers? That size hits more often
> Asteroids with a diameter more than 30–50 metres (100–150ft) are large enough to make it through our atmosphere intact, however, and the chance of this happening is estimated to be around once in every 100 years.

https://www.skyatnightmagazine.com/space-science/chances-ast...
Luckily, the majority of the earth's surface is unpopulated. Most of these rocks hit the ocean or Siberia and cause few or no casualties. The odds of it hitting a major city are quite low.

The article
I wish I was joking.
But there is the rest of the world, and if I'm told that the Africans should not have access to high-speed satellite Internet[0] so that the Europeans can use one specific method of looking at the stars, I don't find that convincing. In time, as we expand, space-based observation will become fairly feasible for everyone. And the satellites we have will decay to the Earth should we fail to keep them up there.
We will build Earth orbital structures and swarms, and we will build Sun orbital structures and swarms, and we will go to the stars, and it will be better for humanity as a whole.
0: https://www.economist.com/middle-east-and-africa/2026/07/02/...
The article makes mention of specific endeavours, like the night-time mirror satellites, which are particularly disruptive to astronomy, and the general risks of high numbers of satellites.
The ability to do Earth based astronomy is something that is of value to all the peoples of Earth, and is mainly funded by the western nations because of their current position as the people with more money.
Commercial satellites are getting bigger and heavier. Launch that can put big and heavy in LEO can put big and slightly less heavy higher up. Add to that things like in-orbit propellant transfer and there is a good chance astronomy sees a golden age in the coming decades (in countries with space access).
I’m not dismissing the problem. Just this analysis as meriting any conclusions. It’s a start. But it’s only part of a full model of how these changes would affect astronomy.
Some sort of modular telescope array that could be launched in pieces and self-assemble in orbit. Something that improves in capacity as more pieces are added.
Everything seems to have stalled in this field, as if it's just waiting for a Starship which may never come.
Most of them launched on the Falcon 9. They just point down to the Earth by default. ;-)
And there are other cubesats testing stuff for x-ray astronomy or gamma ray burst detection, such as:
We’re only starting to truly mass manufacture satellites. A world with millions of satellites means one with lots of satellite production and design economies of scale. (Same for all manner of sensors and optics.)
> as if it's just waiting for a Starship which may never come
Or it may. We’ll know in a couple years. Building a scaling production system for Falcon right now would be silly.
And if Starship never works out, we probably don’t see millions of satellites. It’s a fundamentally tied problem, which is why I say the analysis is incomplete.
I’d love to see an estimate of what a JWST-class telescope would cost to design, build and launch in a world maintaining a million-satellite fleet. My guess is less than $2bn.
Not just the complexity of design, but also cost and complexity of cryo-vacuum testing hundreds of deployment mechanisms any one of whose failure critcially endangers the project. The mirror could also be conventionally manufactured versus requiring gold-plated beryllium [1].
Designing it to not fail at the start & then work without any help for decades must have also made it much more expensive.
Here's a visual to consider the implications of things you can do with actually one million satellites of the kind of size scale being discussed:
https://raw.githubusercontent.com/BenWheatley/blog/refs/head...
Satellites don’t orbit on the ground, which makes the 40m spacing nonsense. And nobody proposes putting a million 120 kW satellites in a single orbit.
They really would never be that closely spaced. To approach those densities in a single orbital shell you’d need hundreds of billions of birds in orbit. Spread across all of LEO (and only LEO) we’re talking orders of magnitudes more satellites (like, quadrillions).
Hence why the horizontal scale bar says "40 m to 43 m": Going to 500 km doesn't add much to the orbit's circumference.
> And nobody proposes putting a million 120 kW satellites in a single orbit.
One of my tentative conclusions is that it would be an improvement if they did. But also, there's better contiguous structures to build if you could put that much up.
It's in my blog post because I'm considering all possible arrangements of ways to do this. Current list:
• Spread them out by altitude while still keeping them in sun-synchronous low earth orbit like SpaceX plan
• Put them all of them in a single sun-synchronous low earth orbit so none of them can hit each other
• Spread them out like Starlink currently is
• Have swarms, where each group has many satellites significantly closer to each other than the usual safety separation, like Google's Project Suncatcher
• Have fewer, bigger satellites, like Starcloud
Matters less than I expected when I started writing. How much so depends on what I end up adding by treating gaps in "full" (up to the safety margin) orbits as the thing of interest and seeing if someone's done a version of this on spherical geometry and also add a time component: https://math.stackexchange.com/questions/270937/how-can-you-...
(That I'm researching such questions should explain both why I'm at 7k words and why I've not published it yet).
(One big surprise to me while researching this: along-track, cross-track, and radial positional error per unit time are all much higher than I would have guessed: https://digitalcommons.usu.edu/smallsat/2015/all2015/58/).
Correct. I wasn’t proposing a realistic configuration. Just showing why OP’s visual doesn’t work for the numbers it gives. (It 1D space fills. I expand that to 2 and 3D.)
Millions of satellites is currently accepted as the maximum carrying capacity of LEO before collisions becomes a PITA.
However, this was not the point of the illustration, which is more "if you can do this at all, you can do better".
I also suspect that to be the case but in order to be more objective I wonder. What's the theoretical maximum bandwidth per square meter (or other unit area) that it can deliver?
The rough hierarchy is: fixed fiber/cable > Wi-Fi > cellular > LEO satellite > traditional GEO satellite. Starlink is a huge improvement over old satellite internet, but it is still fundamentally a satellite system, not dense terrestrial infrastructure.
As a rough illustration, suppose one Starlink beam covers about 63 square miles and has 6 Gbps of usable downlink. At New York City density, that footprint contains about 1.85 million people. That works out to roughly 3 kbps per person. For comparison, network planners typically budget on the order of Mbps per person to comfortably support peak demand in dense urban environments.
You can improve that with more satellites, more beams, more spectrum, and better hardware. But even a 100x improvement only gets you to about 300 kbps/person. Additionally, this all adds cost... that isn't needed for the vast majority of time or space that the sattelites will be over. If the sattelites orbiting over New York also orbit over the Sahara Desert - every $ spent improving NY capacity is also improving the Sahara... but with no return.
The reason fiber, cable, Wi-Fi, and cellular work so well in cities is spatial reuse. Capacity can be reused block by block, building by building, apartment by apartment, tower by tower, and access point by access point. A beam from hundreds of kilometers overhead covers a much larger area.
So Starlink is excellent for rural areas, ships, aircraft, remote sites, disaster recovery, and backup connectivity. But it is not a replacement for terrestrial broadband in dense cities. It solves coverage much better than it solves urban capacity.
Is that the actual figure though?
> even a 100x improvement only gets you to about 300 kbps/person.
TBF even that would be quite useful for lots of things seeing as it's faster than the DSL service I once had. However agreed that it isn't going to replace fiber service and overbuilding to such an extent for outliers would be absurd.
Still, that's quite decent considering it's an estimate of a near worst case scenario.
(that we currently have no way to remove)
is actually 32,000 not just 14,000
what we need is the investment for "space roombas" that go around bumping things out of orbit that are dead or did not de-orbit properly
the problem is all that atmospheric burnup creates a lot of toxic pollution
* https://www.bloomberg.com/graphics/2025-space-orbit-satellit...
Nature takes care of this for us in LEO. I’ve seen no serious plans to put millions of anything anywhere else.
I don't think blocking the view of the night sky is necessary for "human flourishing", actually. Your attitude reminds me of the Victorians, who saw their coal-smoke filled skies as a sign of virtuous progress.
More reasonable minds prevailed, in the end, and now most people have a more balanced view - with the understanding that progress and industry must be balanced with the ecosystem we live in and depend upon for life.
To be able to live well now with much less of that may not have been possible without the sacrifices that came before.

Like, I thought we were for piracy, and against capital colonizing the space of creative ideas? But I guess what a lot of people were fond of was feeling important.
Of course they are. Pre-Green revolution humanity probably couldn’t make a utopia. Currently, I’d argue we need way more energy to make utopia-like conditions available to all.
Technology isn’t sufficient. But I wouldn’t go so far as to say it’s unnecessary, unless one’s utopia permits dying horribly of infection due to minor cuts and abrasions.
Post-Green revolution humanity hasn’t pulled it off either.

What is happening now is we have all our existing structure, and the existing requirement to earn money to live within this structure, and the human creative output we want in our eventual utopia is used to train automata with the express goal to replace humans in those creative endeavors, removing the ability for humans to earn money by being creative themselves.
It is not hard to see things from this perspective when a significant portion of writing is becoming obvious slop, and your liberal friends are having a hard time getting hired or landing writing deals or selling artwork. I would feel less important too; I'm already feeling this way when I review a PR with obvious LLM-generated descriptions and comments that reference the prompt.
Ideally, feeling important wouldn't be pejorative. Ideally, we'd have a way for artists to have food and shelter and continue to produce art. The hopes that AI will cause this to happen are equivalent to hoping WWIII will come along and wipe out 2/3 of humanity so we can start over with United Earth and warp drives and replicators.
Perhaps we could try to destroy those power structures without having a giant war lol, just saying.
> What is happening now is we have all our existing structure, and the existing requirement to earn money to live within this structure, and the human creative output we want in our eventual utopia is used to train automata with the express goal to replace humans in those creative endeavors, removing the ability for humans to earn money by being creative themselves.
Right, I get the frustration, but how many "creators" were doing truly creative and expressive work writing ad copy or making up logos for shoe companies or whatever. The problem people have is capitalism, not the robots and it's short sighted of people to be angry at software tools rather than the system that has forced them to trade their time and skills for the right to exist.
I've literally lost my career before. The one thing that getting deathly ill has taught me is that "all things will come to an end." Someday, that will include me, but hopefully not today, and thanks to modern medicine, hopefully not any time soon. The idea that the only way an artist should be able to justify their right to survive is by shitting out jpgs on fiverr or whatever is as absurd as the idea that that was somehow meaningful work. If you're having a hard time getting hired, pivot. Adapt. Overcome. That's been my life for the last decade since I first got sick - and I'm not saying it's great, but you have to be able to adapt to new istuations. The world ain't going back. Do we become the Luddites and lose in the long run? Or do we "seize the means of computation and build something that strives for utopia?"
> Ideally, feeling important wouldn't be pejorative. Ideally, we'd have a way for artists to have food and shelter and continue to produce art.
I think food and shelter should be available for anyone on earth without any sort of need to justify it. But I do think that feeling really important should be a bit pejorative.
> The hopes that AI will cause this to happen are equivalent to hoping WWIII will come along and wipe out 2/3 of humanity so we can start over with United Earth and warp drives and replicators.
That's a false equivalency. Like, not even on the same planet.
Exactly. The "creative" wankery is just people who got college degrees but don't want to work in offices and/or do things with numbers.
Sorry, jobs that are fun and desireable aren't in big supply. Do something difficult, boring, disgusting, unsexy and perhaps dangerous and you are set.
I had a career in something I loved that was "fun" and even desirable. It was great. I got sick and couldn't do it anymore. I have (begrudgingly, and at times angrily) moved on. I pivoted. I adapted. I did what I had to do to survive and moved forward. I'm not saying I want other people to have to experience that, but I'd say it's given me a sense of clarity about the world that I otherwise wouldn't have.
If you cannot be flexible and adjust under pressure you're going to have a bad time. I think that a lot of people are unwilling to accept change and move forward.
Like, you can also choose to enjoy other things. You can choose to do things that are meaningful that other people don't want to do. Or just... you know, do your own thing. Figure it out. Adapt and do something different. Keep throwing shit against the wall until some of it sticks!
AI adoption is a leadership failure more than a tech one right now. If you make people feel empowered with it, it can liberate work-free lives that humanity benefits from. If you use it to destroy people's livelihoods with no options it's not going to survive a revolution.
The world was already heading towards a dystopian landscape without AI. So many people on this planet live in a horrific dystopia right now, and here comes along something that might help them. Might give us what we need to stop global warming. I'd rather choose something with a 1% chance of working out than what we had before, 0%.
AI is a useful tool, but tools aren't always used to improve lives.
If you really believe this (and I’m not saying I don’t, I just don’t have confidence in it), blocking domestic. datacenters doesn’t preserve that labour value. It just ensures whoever builds those datacenters controls production from afar.
Like, if AI really replaces human labour, does Africa and Europe having few AI datacenters protect it from America and China? Of course not. Not outside a symbolic level that even then would have to exist with the implied consent of the powers who produce.
xAI’s datacenters aren’t currently measurably replacing labour. So no, we’re not. If AI becomes economically competitive with broad sections of human labor, those who control it do have the power to replace humans.
But banning domestic datacenters doesn’t stop them from existing; it just stops them from existing here. If that precondition arises, that’s just a recipe for domestic deindustrialisation.
If you believe AI will replace human labor, blocking datacenters is silly. You want labor (or the public) to build and control them. I’m not convinced AI will replace labor, so I’m not yet at that step.
Oh, absolutely agree. But the datacentre in Memphis is within its jurisdiction. If Nashville decides to stick it with a tax to fund a UBI, they can. Sacramento and Columbus don't have that option.
To be clear, I am not arguing for more datacenters being built the way they are being built. But if you believe AI will replace labour, you want to control those datacenters. Blocking them explicitly cedes that control.
In the 80s, Rupert Murdoch built, in secret, a new fully computerised printing plant built in Wapping.
The workers went on strike, so he fired them. Didn't even lose a single day of output*:
https://en.wikipedia.org/wiki/Wapping_dispute
That is what you should fear from AI. Not the data centres themselves, that we could all be fired and the rich lose nothing as a result.
* [citation needed] :P
Sure. But what would have been better for the Fleet Street workers. The UK banning computerised printing? Or the union owning one?
If AI is going to be to jobs in general as computerised printing was to newspaper printing, just blocking it doesn't make sense. That's my argument.
> Sure. But what would have been better for the Fleet Street workers. The UK banning computerised printing? Or the union owning one?
Oh, definitely the latter.
The only way I see e.g. UBI working long-term is democratic* governments owning the means of production, and in the case of AI futures that means owning the compute, and the power supply for the compute.
Right now, the UK power supply is… privatised.
* small-d, not The Dems, I'm not an American
Like, worker ownership of the means of production and the assets in general is idea. But I'm speaking as an Alaskan who is quite fond of the PFD and think it doesn't go far enough.
We may get that, but only if the ruling class want what the Victorians called a "folly": https://en.wikipedia.org/wiki/Folly
AI is wildly, wildly divergent in the possible futures it brings. It's really important to influence what happens, but don't limit the potential downside to only as bad as feudalism (neither neo-feudalist nor re-enacted): much worse monsters exist than the typical feudal lord.
(Was going to say "among those rulers who needed us alive to fight their wars and grow their food", but then I remembered Cambodia and Pol Pot).
Universal health care? Okay, that's not a new idea, and I'm not necessarily against it. But beyond that it's like... tax the rich. Okay, then what? Get rid of Trump! Okay, fine by me, but it's not like that'll bring us utopia.
Keep going and pretty soon you hit ranting, grievances, nostalgia, and vibes.
They don't have any ideas.
Not that this is unique to the left. The far right is equally rooted in complaining, nostalgia, and vibes. "Woke bad." "Masculinity good." "Trad good." "Why can't we build stuff like (insert random cathedral image) anymore?" Most of them, like most pop leftists, are just full of resentment and have no idea what they want.
I think we give too much air time to critics. It's easy to criticize. It's infinitely harder to build and solve problems.
Once you ignore the complaining, criticism, and hand-wavey vibe-based nostalgia bullshit, you're left with a very quiet room.
Neck beard, well maybe, I am taking the day off and I haven't shaved, though, I rarely shave anyway.
But if you think I developed these views of the world because of a lack of experience in it, you'd be wrong. I've seen life and death and many many things in between. I've written poetry and cried at sunsets. I've seen good men die and bad men win. I've seen justice too. And injustice. I've lived and struggled and fought and made art and raised a family and written code and built things and suffered and read literature in other tongues and loved and laughed and protested and been tear gassed and done things I regret and done things I've been proud of. I've seen the northern lights from the arctic in winter. I've seen salmon streams so think it looked as if you could cross them on foot. I know words in dying languages and worked to preserve them. You know nothing of me.
You think you can understand me because I yearn for a world that's not based on the transactional need to produce economically useful output. You think you can understand the totality of me because I'd like us to strive for an utopic vision of the world. You think you know me because a science fiction show gives me some hope for us building a better world? You know nothing of me.
But seriously, like, what is your optimal view of the world? What would you have if you were allowed to set policy or chart the course of human events or some other such thing?
Personally, I want to see everyone fed, sheltered, and comfortably able to spend their days doing what they want and not having to churn out crap to justify their right to survive. If you disagree with that, then that's your right, but I would be surprised if you disagreed with that.
(God, the fedora.)
I frequently hang out in my driveway in the early evenings shooting basketball and listening to podcasts. I'll see easily several dozen satellites over the course of the hour or two that I typically stay out there. and I don't even live out in the country or anything. I think mostly people are just not aware (yet?) of how rapidly the number of satellites have grown in the last couple years.
Also, what about planes? Those also cause similar light streaks. Another understanding I currently hold is that there is already a method for removing these artifacts
A similar thread that links your examples together is how we all want to be the last person up the ladder. The last person to move into some neighborhood or into the last apartment complex. Or into a country. The last person to have internet access. Now we want to freeze how it is. Everyone after us threatens our experience.
An American with access to good internet for decades is annoyed that their stargazing session isn't what it used to be now that the city is growing and creating more light or that other people are getting to tech up.

By all means, build what you like, but you don't get to dump your externalizations on everyone else. There is no 'We' in your projects, you don't speak for us.
Why don’t “we” just build more cell towers?
Why is littering our landscape with cell towers and power and fiber lines inherently better than putting this stuff in space?
Second, the situation is already so bad that current satellites in LEO already require active collision avoidance systems in order to avoid becoming sources of debris themselves. Starlink alone reports over 1,600 close encounters each week.
What I said applies to space, too, outside GEO, for the number of satellites anyone is currently talking about launching.
> the situation is already so bad that current satellites in LEO already require active collision avoidance systems in order to avoid becoming sources of debris themselves
They require collision avoidance to avoid being lost. There is no risk of a Kessler cascade in LEO right now and nobody who can do orbital mechanics is claiming as much.
We’d need millions more satellites than we have right now to start approaching the point where atmospheric clearance falls below the rate of new-debris production. And even then, you’re talking about a problem in specific orbits for months, maybe years. In the meantime, you get to allow nature to reclaim huge amounts of land from cell towers and conduit.
Who is doing this allocation? Who is going to tell Pyongyang, Beijing or Moscow they can’t launch anymore?
No UN body can command a nuclear sovereign. They ultimately continually consent to oversight.
Why not, though? If any country violates their limit, just issue a concern. If they ignore it, upgrade it to a grave concern. Then they will surely have to obey, I mean, it's grave concern we're talking about, what else they could do?
If I had to trace it to one source it would probably be the Club of Rome and Limits to Growth. Paul Erlich would be a close second with The Population Bomb.
Here’s a great podcast on the latter:

This stuff sounds right because obviously you can’t have infinite growth in population or resource use on a finite planet. That means it won’t happen. The question is “how will it not happen?” The answer right now looks like “as people get wealthier they have fewer kids.” There are other possible answers like dematerialization of the economy which is also a thing.
Before the 70s this stuff would have been called far right and identified with ideologies like authoritarian eugenics and fascism. The 70s is when a lot of “volkisch” proto-fascist and crypto-fascist ideas got a lefty hippie makeover. The other big one is the idea that “natural” is inherently good.
I finally see this stuff getting some challenge from all across the political spectrum, even from the left. In previous decades you only ever saw it get challenged from the right or from what were once called libertarians.
This kind of attitude has for millenia been a dampener on human flourishing. My observation has been that those without empathy or foresight tend to attach themselves to these initiatives to obliterate our shared human heritage to satisfy their own ridiculous misconception of progress. Anti-intellectual, anti-curious, anti-social and so on because they've reached a local maxima in their ability to give a damn about what it means to live a good life and have chosen to spend their life in self-satisfied ignorance.
When the average African live like the average American we'll be truly fucked, probably even before that. We should raise the bottom for sure but we definitely need to cure the degeneracy of the top too
Technosolutionism is a cult. We either put the caps on ourself or nature will hard cap us anyways, in a much harsher way.
And physics lets me get a lot further than "8 billion Americans."
So we can’t see the stars from Munich anymore? Yes, that’s depressing, but we’re not trying to reduce light smog in Munich right now, are we? Because all the buildings that have been build, all the streets and trains, also make it hard to see the stars.
More light is one of the things progress has always brought, and eventually we will just have to accept that we started building in the sky, too.
We should introduce a global agreement that commercial satellites must fall out of the sky within a few years to reduce debris. It should be an agreeable term since the debris hinders everyone doing business up there. Every nation is going to partially ignore it anyway, for military purposes for example. But that’s a different demand than a cap on the total number of satellites.
we aren't?
Bavarian Regulation on Light Pollution, Federal Nature Conservation Act, etc
Municipal lighting is regulated with light pollution in mind and allegedly you get fined over bright commercial lights at night
We talk about satellites as connectivity infrastructure, but I had not considered the impact to the night sky. I wonder if there are solutions like satellites posted further away around the moon with fewer relay satellites shared around the earth?
It seems preposterous that building a data center and
launching it into space would be more practical than building a data center terrestrially. Every problem gets 10 to 100 times harder (Cooling, energy, how are you going to do maintenance on the thing, it's in space?)
The only thing that's easier is you don't have to do any local community engagement.
If a grid connection is the constraint on your project, building an islanded data center with a buttload of solar and batteries seems a lot more feasible than launching it into space. Then you have the option to build a grid connection later and monitize those resourcess.

Not to mention the satellites of Reflect Orbital whose sole purpose is reflecting sun light into night areas
The great observatories are marvels of engineering - a focused effort on technical mitigations to the satellite problem would likely push the problem out for decades into the future.
Two possible paths forward: 1. inserting a shutter into the beam path while a satellite is transiting the field of view of the telescope, or 2. (somewhat worse from an SNR perspective) terminating an exposure right before it's corrupted by a transiting satellite and starting a new exposure once the satellite has passed.
I for one would much rather see effort put into advancing telescope design than blocking advances of our use of space!
I agree with this and I'm not an astronomer btw.
What kind of astronomy knowledge is required to launch a satellite?
there are already several starlink competitors and even other countries planning to launch their own 1000-10,000 node networks
99.9% of species that have existed on earth are already extinct. Climate change happens constantly over long periods. Our CO2 emissions will be background noise on a million year timescale.
Time to ignore the whingers and the NIMBYs and colonize the universe.
