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.

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.
“You guys know we could basically live in a Star Trek style utopia if we get this right, right?”
“The DATA cenTERS are STEALING the water and breaking Taleckshual ProPerty LERRS!”
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.
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.
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%.
Why don’t “we” just build more cell towers?
Another episode of arrogant fantasy in the ponyworld.
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.
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.
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.
More regulations would just have the result of cementing a monopoly for Spacex.
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 wish I was joking.
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.
Source?
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.
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.
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.
> For the SpaceX satellite mega-constellation, he found that dozens of trails would appear in each image taken two hours into the night with ESO’s Very Large Telescope (VLT) at Paranal Observatory in Chile
Not to mention the satellites of Reflect Orbital whose sole purpose is reflecting sun light into night areas
there are already several starlink competitors and even other countries planning to launch their own 1000-10,000 node networks
