      Well, this was actually fkning concerning. Ofk is not like other Company aren’t playing to launch thousand of satellites too. There should be a serious regulation and some heavy changes in the metal alloy used at very least. I’m sure that Trump already has a plan about it…

      … ofk i’m fking kidding. Vote [everyone else] x president .

        So we’re starting to look at aluminum debris in the upper atmosphere, when are we going to look at carbon fibre debris? Or rocket fuel in the upper atmosphere? We dont know what any of that shit does. Im going to hazard a guess that it does nothing good.

        If you were to light ten thousand Starlink satellites on fire in a bonfire on the ground people would put you in jail. When it happens in the upper atmosphere its called progress.

          Completely stopping the launch of new satellites will simply not happen. The only realistic response is to face the problem and improve the technology.

            Just like they’re doing with the climate catastrophe.

            Reasoned, sensible change, carried out quickly and paid for by the companies responsible.

              Well, it did work for the ozone hole.

              It should work for the current climate catastrophe and the aluminium thing too, if about 50% of the electorate, 90% of its representatives, and 99% of the people in charge of big companies weren’t mentally handicapped imbeciles, too (if we count being a psychopath as a mental handicap).

        Type of metal doesn’t matter, it’s any particle that leftover CFCs from the 1970s can stick to and make it more likely for them to react and destroy ozone. The ozone hole is over Antarctica and changes size seasonally because high altitude ice clouds do the same thing, smoke from forest fires also does it.

      You can criticise them for that while being glad they are a reliable astronaut transport, unlike Boeing. The world is not black and white.

        I am glad of that, but this is what I responded to:

        SpaceX is nailing it. I just hope that the future will remember the terrific work that Gwynne Shotwell and many others did while “someone else” where busy tossing money away.

      Aluminum is a major element of the 5200 tons of stardust per year. Sadly found no numbers.

      Ehhh needs more study. Aluminum oxides in the atmosphere actually provide a cooling effect. That being said, we don’t know much about the health implications yet.

        If you read the article the hazard is the Aluminum Oxide could deplete the Ozone layer. So a disruption to a different ecological process rather than the Greenhouse effect.

        Right on. The “cooling effect” will hopefully offset all the kerosene and methane they’re injecting into the upper atmosphere and oceans.

          They’re injecting water vapor and carbon dioxide, as well as soot (not kerosene or methane). I don’t mean to imply that it’s not an issue, but that more study is warranted (the article says the same thing).

            Do you know what those clouds are that come out of the engine at cut off and start up are? Not water vapour or carbon dioxide.

              If we’re talking Falcon 9, the ignition is using TEA-TEB, a fairly nasty hypergolic. It burns to water vapor and carbon dioxide, plus some boron oxides.

              Starship doesn’t use a chemical igniter, so yes, there’s probably a small amount of methane that escapes during ignition. Generally though the combustion for Starship is incredibly clean, with something like a 99.5% efficiency.

                Theres nothing to ignite unless the pumps are running full speed. The pumps keep running after after the fire goes out. What are those pumps pumping?

          Oh boy, you’d better not look at the cattle industry then.

          Every rocket launch ever done in history doesn’t make even a blip on the graph for human-related carbon emissions.

            I love that “drop in the bucket” justification. In the 1900’s car exhaust was a huge innovation because it did away with the mountains of horse shit produced by carriages.
