That is correct, however there isn't enough stuff in those orbits for Kessler Syndrome. Meanwhile the satellites they are referring to in the article are SSO observation satellites and Starlink. All of which are in sub 600km orbit. And for the near future we have SpaceX announcing Starsheild, which is Starlink satellite busses used for military purposes, and that will link into the Starlink network forcing it into a similar height.
Sub 600km is the only place with the necessary density, but also the safest place to have it happen.

Not all military satellites are in very low orbits. And you don't have to go full Kessler to make a real mess for decades if not centuries.
Plus, once you have your first space war, that changes the dynamic of space entirely. There's no guarantee that you can go back to the honeymoon period of space utilization that we enjoy right now. Denial could become the long term strategy.
The notion of proliferating the militarization of space is pure insanity. It has a logic to it but is still insane nonetheless. And to do it unilaterally and, to some extent, by choice, makes the US the baddies.

The only orbit with enough satellites in it for Kessler is LEO, and thats do to starlink. Simply put the other orbits are not at risk, and will remain that way for the mid future. Also you specifically said locking us out of LEO in your first comment.

There was never a period if time space wasn't militarized. The very first thing we did was develop spy and communication satellites. The fact is the second a serious face war started ASATs were hitting ever military bird they could, and the only counter to that is hitting early warning satellites could be seen as the opening to a preemptive nuclear strike.
And to call the US the badies when every other country that can is doing the same is just a dumb America Bad argument. Or did you forget OneWeb is owned in part by the British government?

Kessler is a red herring. The debris from a space war is enough. And when you consider the first space war might just end the peaceful exploitation of space, that by itself should be enough to give you pause.
No one is militarizing space to the extent that the US is. Prior to the Space Force, the US had a qualitative and quantitative lead in space militarization. With Space Force escalating and proliferating militarization, that lead is only going to increase along with the tensions that come with all that saber rattling and proliferation and escalation.
And a US military space hegemony threatens everyone else's early warning systems as much or more than it protects ours. Which is a significant destabilizing factor making nuclear war and/or a space war to end that hegemony all that much more likely.
Regarding OneWeb, last I checked, the Brits aren't constantly talking about proliferating space militarization and "battles of attrition" in space. And I don't recall them creating a whole new branch of the MIC dedicated to space war.
If you're the little guy in the space military race, maybe it makes sense to rattle a bunch of sabers and talk about proliferation and coyly hint about all your fancy new space weapons.
But if you're already the top dog by a large margin and you do all that stuff, dramatically destabilizing the balance of power in space and escalating towards the first space war, that's what makes you the baddie.

Kessler isn't a red hearing as that is what locks us out of space. Either a war generates enough debris to cause Kessler Syndrome, or it doesn't. First case locks us out of that orbit, second case does not.

Regardless of them talking about it or not, One Web satellites serve military purposes for the British military. Furthermore the fact they did do this shows they want more space assets as they could continue to rely on US assets as they current do.

How? That doesn't even make logical sense. Observation sats can not threaten other countries early warning systems. It would take actual armed spacecraft to do it, and in that case The USSR had a Cannon on a space station years ago. Meanwhile the US hasn't had anything.

I get it, you are worried about the outcome of space getting militarized, but we past that bridge in the 60s, and pandoras box is open. But you are just blaming all of it on the US rather then accepting every country would do the exact same if they could. Atleast with the US maintaining dominance the situation remains stable, and thats the best you can hope for.

And a simple debris cascade is enough to lock us out due to debris for as long as it takes the debris to deorbit which could be decades or centuries.

You literally told me Kessler syndrome doesn't matter earlier, the you say this which is literally Kessler syndrome. At this point I have enough proof to say you don't know what you are talking about.
BUT
one more time. The orbital altitudes that have enough shit in them to have Kessler syndrome or a debris cascade or whatever you want to to call it are low enough that they will self clear inside of 5 years. Outside that low orbit any debris created will stay for much longer, but there isn't enough satellites to have a chain reaction that locks us out of them.
>And the destabilization that comes with the US aggressively asserting its space hegemony puts the US and the world at large in as much danger as the "defense" capabilities the Space Force brings to the table.

These are both very dangerous to the continuation of the peaceful exploitation and exploration of space. This is what makes the US the baddie here. :(

Kessler doesn't matter because you don't need a full on Kessler to deny access to space. A run of the mill space war or minor debris cascade will do just fine.

All stuff we already had. The balance of power isn't changing. The US military has operated on the concept of full spectrum dominance for the last 30 years, and space is part of that. The US dominating the orbitals is nothing new, and US upgrading to newer tech as it becomes feasible is exactly how its always worked. As I already have said repeatedly, we have already seen China use a micro satellite that rendezvous with others. Then we have the X-37B and Chinas copy. Or the Space shuttle having giant wings to let it literally steal a Soviet satellite then land with it before completing a full orbit.
You are acting like this is new shit. Its not.
>Kessler doesn't matter because you don't need a full on Kessler to deny access to space. A run of the mill space war or minor debris cascade will do just fine.
That is still Kessler syndrome. Kessler syndrome is simply getting enough satellites and debris up that it degrades the operational lifetime of satellites in that orbit, and it can accelerate. It never actually required the orbit to be unusabale.

That combined with the military utility and competitive advantage granted by space assets such as Starlink really ups the chances that the next big US war will start in space. Or some other war will bleed over into space to deny the US or its allies the use of those competitive advantages.

simcoder t1_iyzagem wrote
I guess we have to do this one thing at a time.
The point is you don't need a Kessler. That's the worst case scenario. An ordinary space war generating debris fields with century long decay times is good enough. Or a midling debris cascade that doesn't go full Kessler.
What part of that aren't you getting????
Doggydog123579 t1_iyzbu8p wrote
LEO can't have century long debris fields, and its where all these mega constellations exist, so other orbits don't really matter. furthermore all of the current ASAT weapons can't hit higher then high LEO anyways, so any other area is irrelevant. And a midling debris cascade is still Kessler syndrome. Kessler syndrome is a spectrum. It just means you have a debris cascade that is negatively effecting satellite lifespans. That can be anywhere from removing weeks to removing us from the satellites operating life. Making it impossible to use them was never a prerequisite for it to be Kessler syndrome.
simcoder t1_iyzdkow wrote
Well you're wrong on a number of points there. Let me try to explain a couple of them to you.
LEO very much does contain century long decay orbits. LEO extends out to 1000 miles or so. Technically, at the extreme, that could go all the way to thousand year decay. Maybe more.
I think most of the military stuff is a bit lower than that. But, if you're right and ASAT weapons are limited to lower LEO orbits that seems like that would be a pretty decent incentive to put your important stuff up there out of range of the easy ASAT kill.
Kessler is the long term debris cascade that runs away on itself...over the long term. If your theory that the debris clears in a few years and is nothing to worry about, then, it's not Kessler. Because it's over in just a few years and doesn't run away on itself. It's just a middling debris cascade that creates a little bit more debris and then decays.
The point being that you can have a debris cascade that eventually peters out. Technically, if some debris hits just one other satellite creating more debris that would qualify as a "debris cascade (of 1)".
And a debris cascade that eventually peters out is by definition NOT KESSLER. All debris probably contributes in some way to the long term runaway Kessler. But not all debris cascades are Kessler.

The vast majority of satellites are sub 600km, so while true its effectively irrelevant.

Good plan, except those satellites don't work at the higher altitudes.

You are so focused on the theory of it you are missing the forest for the trees. Kessler syndrome was based in the idea of a debris belt forming in orbit from a chain reaction of debris hitting satellites and other debris. It doesn't need to be growing or sustaining itself to still be Kessler Syndrome, it just needs to exist. VLEO experiencing such will still be clear within 5 years do to the low altitude. But that is still Kessler syndrome as a cascade generated a debris ring.
Or in simpler terms you have it backwords. ALL debris cascades are Kessler Syndrome, But Kessler syndrome can include other things
To quote the original source
As the number of artifical satellites in earth orbit increases, the probability of collisions between satellites increases. Satellite collisions would produce orbiting fragments, each of which would increase the probability of future collisions, leading to the growth of a belt of debris around the earth. This debris flux in such an earth orbiting belt could exceed the natural meteorite flux, affecting future spacecraft design.
Oh look, nothing about it making space unusable or being permanent.
simcoder t1_iyzg6if wrote
Not all debris cascades runaway. To be Kessler, they need to runaway. Your pet theory of decay in a couple years and everything's fine is not Kessler. No matter how much you try to shoehorn it in there. I'm kind of shocked you're still trying while so obviously being wrong.
And I just want to make sure we're clear that you can have decade or century long decay times in LEO. And that we don't know if the military has stuff higher than VLEO. Particularly, if you are correct and going higher gives you some immunity to cheap ASATs.

The reality is that a space war could very well lead to long duration debris fields that will impact space operations for the duration. And, as I mentioned earlier, the first space war could change the way everyone operates in space for the foreseeable future. Particularly given how much cheaper it is to deny space than it is to "defend" it.
Right now it's an "everyone's-land". After the first space war, it could turn into a no-mans-land. And to the extent the US escalation in space plays a part in that potential future, that makes the US the baddie in space right now.

We actually do know the orbit of every military satellite, because you can't hide that from a telescope. Pick any satellite and I will tell you its exact orbit. The vast majority are under 600km because of their missions. Which puts them in range of ASAT.

While you are correct in your statement that you don't need a full kessler to affect LEO, you are vastly overestimating the amount of debris that would be needed to create a kessler of significant enough size to stifle spaceflight on any level. The volume of upper LEO is so vast that there simply aren't enough satellites there to create a debris field big enough in the first place, not even mentioning how difficult it would be to create the debris initially, considering pracitcal studies conducted by the US military have shown that current ASATs are impractical at best, entirely useless at worst.

Very often, you'll hear from the fanbase that could happen but it wouldn't be a big deal because it will all deorbit in 5 years.
But it actually would be a very big deal for everyone involved in space. Anything between the upper shells and the ground would likely be very negatively affected up to and including getting destroyed.
A lot of people would likely end up being very very unhappy that the hubris of a 30k constellation caused the world to have to put their space ambitions on hold for 5 years and sacrifice whatever got in the way of the carnage.
What you're doing here is very similar.
A space war generating a bunch of debris would be very bad for space business and could cause either a partial or complete shutdown of space while everything clears out. Any debris higher than VLEO would likely have knock-on effects for years or decades down the road.
And the very fact we had the first space war resulting in a bunch of space assets getting blown up would likely have a significant cooling of people's space ambitions in general. And could result in earth orbit becoming a military no man's land if the military tensions continue.

Ugh. Not this shit again. I'll go through it real quick because I can't be bothered arguing with people who ignore common sense specifically when it come to starlink.
1- Starlink satellites cannot and will not collide. Spacex keeps them at different altitudes and monitors them constantly, with redirections taking place if they are on course for a collision. Spacex will never allow a collision to occur as it hurts them more than anyone else.
2- Any debris from a starlink collision will burn up in the upper atmosphere within 90 days, it is physically impossible for it to stay in orbit. The 5 year number is with constant firing of their ion engines, not without them.
3- I have explained this time and time again. There is not enough potential debris his high LEO to stifle spaceflight. LEO has more than enough but it will all burn up within a small time frame.
4- If you're going so be this whataboutist over this, war in space would be a war on the ground too. It would go nuclear, and humanity would be wiped out. Therefore, there is not point in even considering a kessler beyond that.

I didn't realize that you were so naive...
And a space war is almost certain to happen eventually. Same with a nuclear war. That's what humans do. It's a shame but that's reality for you.
To ignore that sad reality of humanity just makes it that much more likely when go around aggressively militarizing space.
