    Yep, they are in Low Earth Orbit. A place that has a very, very small amount of air, so the satellites experience drag, lose speed, eventually the propellant tanks run dry, and they burn up in the atmosphere. The ISS experiences the same thing, which is why its altitude slowly falls, then you see a sharp increase as they push to a slightly higher orbit.

    At the altitude the SpaceX satellites are at, they only passively stay up for a few years. With the onboard propulsion giving them each another few years.

    Complaining about Kressler Syndrome

    Complaining about Starlink

    Pick one, asshole. As shitty as Musk is, Starlink is in too low of an orbit to cause Kressler Syndrome

      The only worry about low earth orbit is something survives reentry enough to become a bomb. these are enough to destroy a house if that happens - my undertanding is this can’t happen but if they did

        Starlink satellites aren’t large enough to survive the heat of reentry. A more likely concern is the various materials vaporizing and dispersing into the atmosphere, as was mentioned in the article.

        That being said, calling them “heavy metals” like the interviewee did is rather dubious. We’re not talking about lead, as what most readers imagine when they hear that term. It’s mainly aluminum and copper. The person interviewed is picking their words to overexaggerate their claims

    Half the size of a pickup truck… a Mazda compact, or a jacked up GMC Hemi half ton?

    Even just saying Ford F150 gives a lot of leeway.

    Yeah that’s what happens to absolutely everything in Low Earth Orbit in just a few years. Well, unless you keep pushing them back up like we do to the International Space Station.

    These satellites are doing exactly what they’re intended to do. These are actually pretty small satellites overall, there are a lot up there quite a bit larger that deorbit and burn up on re-entry just fine as well.

    That’s part of the reason things are sent to LEO specifically, because their orbits naturally degrade and they naturally deorbit themselves without needing any assistance or fuel. It also means if a satellite in LEO fails quicker than planned, is put in an incorrect orbit due to a launch issue, or just failed prematurely, it will fail-safe and deorbit without any assistance.
