    This is completely factually inaccurate. 2 minutes on Google will help you learn but seeing as how you’ve been spewing crap all over this thread I don’t think it’s worth my time to even bother helping you understand.

        Shortest answer is that even if all Starlink satellites suddently exploded at the same time for no reason, they’d fall back to Earth in a matter of weeks. They’re waaaay lower than the other satellites you’re thinking of (see discussion on geo-stationary satellites for why), so they need to be actively pushed every few days just to stay up. They’re so low they’re still subject to atmospheric drag.

            They’d burn up / vapourize. This is partly why it took them so long to get their space lasers to work (for satellite to satellite communications); these things usually are usually based on a crystal that wouldn’t burn and could hurt someone when the satellite falls.

                Man, you really are looking for any excuse to hate on SpaceX, right?

                If you’re that worried about pollution, just look up the mass of a starlink satellite vs the mass a coal plant burns every hour… Even if the satellite ends up vapourizing as 100% pollution, I’m pretty sure it’s orders of magnitude below other industries like coal power or aviation.

                  Sure asking questions is making excuses to hate SpaceX.

                  Is it polluting or not? I actually expected you’d show it wasnt at all. I literally don’t know either way but if you aren’t comfortable explaining your position on it thats fine.

                    Just asking questions”… It’s just a bit suspicious that as soon as the safety aspect was proven to not be an issue, you immediately switched to another angle.

                    But to answer your question, yes, vapourizing someting made of metal and plastics in the upper atmosphere could certainly count as pollution, and we don’t really know the effects it might have on it because no studies have yet been done.

                    What has been done, though, is a study of how many meteors fall on the earth every hear: early estimates in the 60s were of about 100,000 tons per year, but further studies (1) showed this was grossly underestimated and more accurate values would be about triple that.

                    Starlink has launched 6,054 satellites in orbit (2) that total about 3,838,042 kg or a bit below 4000 tons. Even if they all fell in the atmosphere tomorrow, it’d only amount to less than 2% of this years’ “stuff” that burns up in the atmosphere (the rest coming from natural sources). Honestly I don’t think that’s significant, but I’ll concede that we don’t really know for sure. I just think that there are other more immediate, much worse sources of pollution that people should direct their anger towards.

        Search the web for “star link Kessler syndrome”. It’s well documented. It’s also discussed elsewhere in this thread.
