    falling from the the sky and burning is a good thing, bigger concern is them staying up there for too long

        communication satellites are low earth orbit to reduce latency, that means +25000 km/h velocity to sustain orbit, and would also have a very shallow entry angle, that combination means total vaporization

          i mean, with that many satellites what are the odds (i have the smoked 2 joints stupids) something fucks up and it doesn’t come in at that shallow entry angle?

            Most of the energy from the rocket that launched the satellite went into pushing it fast sideways. If you wanted to slow it down enough to drop straight down, you’d just about need a second rocket to stop it.

          Low earth orbit is most survivable reentry trajectory… coming in at a higher angle significantly increases the heating.

    As was always the plan for these satellites.

    The article raises a vague concern about Kessler syndrome. This is exactly why these satellites are designed to deorbit once their useful lifespan is finished. I don’t see what the point of this article is at all.

      Part of the plan, sure, but that doesn’t mean it’s a good plan. They don’t have control of where the debris lands, and Starlink doesn’t take responsibility for cleanup when it lands on others’ property.

          Per the article, sometimes they burn up, sometimes they don’t.

          The big culprit I was remembering isn’t Starlink, but SpaceX, with the debris being potentially lethal (over 6 feet, too heavy for one person to move.)

          From the same professor: https://wlos.com/news/local/professor-spacexs-lack-of-accountability-for-space-debris-frustrating-nasa-samantha-lawlwer-university-of-regina-saskatchewan-canada

          Musk’s companies are notorious for lack of responsibility. At least Cards Against Humanity held they’re get to the fire for a minute.

            SpaceX has made changes in the past so the dishes break up better. That could have been one of the earlier dishes, but maybe it was also one of the ones that failed to properly insert into orbit which changed the re-entry characteristics?

            The big things like you mentioned wouldn’t be starlink. That’d be from something larger like a 2nd stage that came back down and didnt fully burn up. Thats a risk with everyone, mega constellation or not.

            Luckily, starship will be fully reusable which will prevent that, but the trade off is, if starship is successful, a failure during re entry is going to risk having a vehicle designed not to burn up, land somewhere it shouldn’t.

            Similar risks to the shuttle if it blew up, but these will be flying much more frequently

          I ran into this dramatization for media hits before, with the complaint about rocket launches and their contribution to pollution. People were all about getting out the pitchforks, especially since it was mainly about Elon Musk, but when the actual numbers were mentioned (very small), suddenly, I was the bad guy. No one likes real facts.

          Now, should we be launching so many things that are designed to fall back down so soon? Probably not, that’s the mark of a disposable society in high gear. But how we’re doing things, and why, should be the focus, not a headline that makes it sound like things are falling out of the sky to hit people.

        Having spent some time doing licensing work for an orbital vehicle, the reason the reentries are uncontrolled is pretty stupid bureaucratic bullshit. Because of the way the licensing process works, its much easier to get an uncontrolled reentry license than a controlled reentry license. The FAA claims to prefer controlled reentry so the debris comes down in some uninhabited part of the ocean, but because they make it way easier to get a license for an uncontrolled reentry thats what everyone does. Being the FAA it takes forever to change anything, so maybe they’ll change the rules shortly after its too late to matter.

          Nah, I just wasn’t looking close enough, it’s just a simple paste of one image on top of another from the same angle. If you follow the line where the truck ends upwards, you can see a similar line on the roof of the building and the tree in the background doesn’t quite line up perfectly (but it’s close enough that our brains assume it’s fine).

          That might have even been done in paint rather than gimp or ps.

            There is some line on the roof, but the roof still strangely lines up. The tree in the background nor the sky have a visible line.

            Furthermore the text on the tire is garbled, and the whole image has this “covered in vaseline” feeling to it.

              You’re right about the sky, though I think the tree does have a line but the blur hides it (I can see it when I include the line in the roof but not when I block it). I’d say that it is more sophisticated than paint, but that an image editor was used to take the cloud from only one of the images.

              I disagree that the tire text is garbled. https://www.bfgoodrich.ca/en/auto/garage/articles/making-of-the-ko3-tire here’s a picture of a similar tire with the same text. AI might have been used for some of the editing of that transition, but I don’t think the source images were genAI.

      It’s impossible to regulate space. Even if your government put restrictions on putting things in orbit, the company could just launch under the flag of somewhere else. Blanket banning of commercial space programs would require a universal treaty or would lead to an act of war. Im not saying the US shouldn’t try and do something about space trash, but it’s not as simple as “just ban corporations from space”

          SpaceX bought a retired oil platform at one point to try and use as a launch point. It didnt work, but if you told them they couldn’t launch from land they’d probably figure a way out.

            Doesn’t matter, authorities in the jurisdiction where they are based and also where there clients are can just fine them into oblivion. This government won’t but they could, if they wanted to. That’s the whole point of the law, regulators “just” have to write it down for it to become what everybody must follow, or have terrible consequences. They don’t have to be physically blocked. It’s not a technical problem.

              That’s a bigger thing than just closing the spaceports to private companies as OP was suggesting.

              That would likely be politically more difficult to pull off than closing existing ports.

              edit: Just to clarify, one is saying, sorry you can’t use our public resources. The other is saying, sorry you can’t build your own resources either.

        Space is extremely regulated, SpaceX just gets permits approved to do anything they want because they’re extremely cooperative with the US military and CIA.

        Rocket Lab is a private rocket company that launches from New Zealand, but part of the company is in the US so they still have to get an FAA license to launch from any country. No matter where SpaceX goes they would need FAA and FCC licensing.

    Their hastily built escape rockets coming face to face with chunks of debris travelling at orbital velocity, would truly be poetic justice.
