We have a bright future full of endless "space-junk". As the price to orbit drops, people will inevitably send up more and more satellites that have questionable value. In 100 years will the sky at night just be a massive grid of dots moving across the sky?
Who will create the first advertisement in space using satellites as pixels to create their company logo? Maybe they can add some color and animations for kicks.
Edit: Another note on space junk is the effect on our atmosphere with all the "burning-up" of various materials. Apparently they don't just completely vaporize, but instead leave behind micro particles that float around for a long time. People are studying this and hopefully raising appropriate alarms (Making the case for wood satellites).
Hank Green did a video recently advocating for an "orbit value tax" -- like a Georgist Land Value Tax, but for orbits. This tax would, among other things, help fund orbital cleanup and internalize the externality of polluting orbital shells. It's an idea that deserves more discourse IMO.
Here is the video: https://www.youtube.com/watch?v=VLjW6zuYmos
And who does the tax get paid to? Some mythical Global Government that will totally work this time?
The Dutch figured out how to do collective dike maintenance a millennium ago without inventing mythical super government. Collective rules worked just fine.
I encourage you to reflect on this bias. I suspect you're taking the American state as a template, and extrapolating its incompetence. The history is filled with different ideas - some of them far older than America itself.
Hell, I'd call America a place so naturally rich, it's practically the case study how much dysfunction can be papered over with money instead of statecraft.

My new startup, SPECTRE.
It's a new SaaS play - Satellites As A Service. That is, your satellite gets to stay in orbit as long as you pay me.
Otherwise my satellite killer eats them.

The video discusses this directly.
Any company removing space debris from orbit. Like a carbon capture price to offset your launch.

Ugh. People already trying to find ways to gate keep space by raising the financial barrier to entry before we've even been able to capitalize on cheap space flights. I'm sure SpaceX and others will be against this until suddenly, they're not, when they realize they're one of the few that can even afford to pay it.
Like when Amazon finally had warehouses in all fifty states and suddenly quit campaigning against online sales tax.
One of the arguments Hank makes in the video is that SpaceX is (via starlink) rapidly occupying large portions of useful LEO shells, which crowds out future competitors or users of that orbit (i.e. you can't put more satellites into the orbit without risking collisions, especially satellites that aren't part of the existing constellation), and that the natural consequence of not regulating orbital space in some way would be to lock in the first movers in an orbital shell as the only organizations that have access to that orbit.

How else are the entrenched interests who control most of what happens on Earth to guarantee their continued dominance off world? And yes, it’s exactly like the creep of taxation, copyright police[1], and censorship into the Internet when they realized people were going there in part to avoid those.
[1] I’m not really mourning the loss of Napster, but rather rolling my eyes at the way YouTube has made having more than 6 seconds of any song a death sentence for the video, killing fair use dead, since demonetization directly halts distribution of a video.
I mean, presumably, the tax would apply per-spacecraft with a price adjustment for orbit lifetime and how busy a particular orbit is, so a small constellation of 5-10 short lived microsatellites wouldn't have a huge entry barrier.
> People already trying to find ways to gate keep space by raising the financial barrier to entry before we've even been able to capitalize on cheap space flights.
Space flight is a typical "tragedy of the commons" scenario. Like radio waves (especially on HF), space orbits are a finite resource... and not just problematic for other satellites, because ground-based space observation gets more and more impeded by satellites.
Do you think Russia will be willing to pay a tax on their new Rassvet constellation?
Seize a few shadow fleet tankers to pay for it.
(This is already happening, today, for other bits of their misbehavior!)
> orbit value tax
How about No?
LEO satellites are the size of a car and are spaced apart by the size of a state. They also all are in slowly decaying orbits and will fall out of the sky on their own accord in 10 years or less (they are designed with intentional structural weak points to break apart and burn up on entry). The concerns you have are valid and very real, and shared by the people designing these things.
This is on a similar scale to complaining about there being too many tennis balls on the surface of the earth.
Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.
Nah, it's more akin to complaining about the number of bullets crossing your path. They don't occupy much space, but the fact they're moving at 17,500mpg means you want to ensure you avoid them, and ideally for there to be fewer of them fired at more predictable intervals.
I feel like LEO is a convenient speed to know if you are someone who often asks "how fast is that". At Mach 23 it's a lot faster than sound, and on the slow side of "how fast space stuff moves".
Of course it's still 3 orders of magnitude slower than galaxy collisions, which themselves are colliding at roughly 1% of the speed of light.
There is a legitimate concern with space junk hitting useful stuff or even manned spacecraft but I think space is big and the sky won't appear bright soon. Not all satellites are that reflective and they need to reflect the sun, they don't just glow visibly.
At present, I don't believe there are industry standards / codes mandating minimization of reflectivity. My understanding is that SpaceX has engineered for this from their own internal requirements and "goodness of their hearts" (which may be related to avoidance of public pushback). As we anticipate a major scale-up of LEO in the future, it follows that "cost pressures" may (mal)incentivize players to skip this concern.

I hate this cynicism in everything. People didnt work there 10 years ago to be millionaires in a far away IPO, they worked there because they are Team Space.

In practice the lower cost of access to space had made it viable to star requiring people to at least deorbit their upper stages, something that was long a no-go, with the excuse being that the extra fuel and redundancy would eat too much into the payload mass.
Nowadays it is generally frowned upon if you leave upper stages in orbit or if your satellite fragment spontaneously. There are of course exceptions (like some chinese launches leaving massive core stages in orbit that ten randomly fall back a couple months later) but AFAIK the situations seems to be actually improving due to the added robustness, that was only made possible by cheaper access to space.
A major plot point in the Red Dwarf books is about Coca-Cola sending a fleet of space ships out to blow up stars so they can spell "Enjoy Coca-Cola" in the sky.
One of those ships crashes and the boys from the Dwarf find the service mechanoid, which is how they get Kryten.
Oh great the NIMBYs are coming for space now.
Not Above My Back Yard - NAMBY?
On the positive side, clearing out all this space junk could end up being a meaningful contributor to global GDP. See also Planetes [1]
[1] https://en.wikipedia.org/wiki/Planetes
I wish clearing out all the CO2 from the atmosphere became a meaningful contributor to global GNP.
Thanks for reminding me, I started watching this and forgot about it!
Not a grid of dots, a ring! https://earthsky.org/human-world/kessler-syndrome-colliding-...
It's a tragedy of the commons situation. And given how well we are able to regulate those kind of situations globally, I'm rooting for the ring.
Satellite broadband stonks in shambles after the inevitable Kessler syndrome
It's already a massive grid of moving dots. You can see it from the ground in certain dark-enough areas, but in order to see it in space you have to get outside LEO, like Artemis did. They don't have lights but they are shiny and they catch the sun, making them easily visible from certain angles, which the Artemis photos illustrated.

That map makes it look extremely crowded. Actual relative satellite size is many magnitudes smaller than each of those 1-pixel representations.
Dark night skies will probably be one of the main selling points for the off world colonies. I can see the Bladerunner-esque ads now.
Junk yes, but think of the new science and industry it will enable as well. Microgravity experiments, new space stations, space tourism, new types of manufacturing in space, asteroid mining. Any technology is a double edged sword, but the benefits surely outweigh the drawbacks here.
It’s already starting to be like that. If you get far enough out into the bush away from light pollution and watch the stars for a bit, you can see the grid of satellites orbiting. It’s kind of cool but also kind of depressing.
"Unobstructed view of the stars" will soon be how space tourism companies upsell their customers to higher orbits.
Incredible how the first instinct is just to complain about progress these days. The degrowth mindset is really taking hold.
There is a huge amount of "space" available even in low orbital shells. Which also naturally decay.
There's a reason most of the western world isn't capable of building anything these days.
Yeah. And on the other hand, Chinese culture tends to embrace and optimize progress. I blame the French for infecting western universities with the de-growth mindset.
>but instead leave behind micro particles that float around for a long time. People are studying this and hopefully raising appropriate alarms
The number of satellites required to create a measurable number of particles in the planet's atmosphere would be impossibly large. How much mass to orbit do you think is required to create a 1 PPM increase in earth's atmosphere of these "micro particles"?
I find it extremely disheartening how much anti-technology, anti-science, and anti-progress sentiment I read about lately.
People are not worried about the mass increase in the entire atmosphere, but very selective layers of the atmosphere (mesosphere and stratosphere). These are delicate layers that are highly affected by nano particles created from satellite burn-up.
