    they already have anti-satellite missiles, they just need to build alot of them. or have jamming satellites of thier own,.

    Yay! but the Ukraine war effort Boo! but less space junk! Yay! but all those just… normal Starlink customers who need internet Boo! but fuck Musk! Yay!

    I’m gonna need a drink.

      Low Earth orbit means that the debris will get dragged down by the atmosphere before it becomes a cascading problem. Thankfully.

        So we can directly pollute the upper atmosphere with heavy metals? I’m sure that’s a good thing. /s

          Orbits are elipses, which are loops. So after the explosion gives an object more energy it’s in a new orbit right? That orbit has LOOP. Which means it has to come back to a similar point it’s at now. Therefore if an object passes through low orbit, no one explosion can make it be in a high orbit. At best it’ll be an ellipse with a point in high orbit and a point in low orbit.

          Any amount in low orbit means a decaying orbit due to drag with eventual falling out of the sky.

          If you get to the high orbit point and you get a SECOND explosion that’s perfectly timed you could theoretically enter a new high orbit that’s stable over the long term and contribute to Kessler syndrome.

            Blowing up a low orbit satellites can lead to many particles reaching high altitudes, if only temporary as you say, where they can cause cascades. Unstable orbits make the probability of collisions smaller, but they need to shatter only one satellite to end up with a mess in stable orbits.

        GPS is comically higher than starlink.

        I’d be much more worried about a direct attack.

          Yes, but a screen of tiny reflective particles spread through orbit between the Earth and the GPS satellites might cause communication problems.

          Yea but you still have to get the GPS satellites up there safely. I see though that it might actually not be that big of an issue of GPS.

    That is inevitable. The sky will be filled with the trash of struck down satellites and nothing can leave earth for a while. Before starlink, China had already demonstrated that they can shoot down satellites. No investigation needed.

      Even the worst Kessler syndrome scenarios don’t stop new satellites from being launched through the debris-containing altitudes to reach clear orbits.

    We already have the technology if memory serves. Since civilians are the last to know, there have probably been satellite killers in orbit for years.

    It’s fun for Musk to get fucked, but I believe Ukraine uses Starlink to defend itself

    According to the authors of the concept, if the resilience of a satellite constellation is ensured by its sheer number, then the response should be a weapon cheap enough to destroy satellites faster than SpaceX can launch new ones.

    Smells of the good old forgeting that the target wont just sit by

    At least they arent putting everything in one basket this time with physical destruction being the last option

    Whats a satellite constallation destroyer but a anti ICBM weapon under a diffrent name?
