How Much Do Rockets Pollute? Are They Bad For Our Air?

Great question and I suspect you are correct regarding the impact being small (Tim Dodd the everyday astronaut, made a great youtube video about rocket launch pollution, check that out for sure [this video] ). He concluded that even with increased launch rates, the pollution remains small compared to other industries such as the airline industry. Not the same thing, but I'd argue the impact from satellites and debris burning up is less than the rocket it took to get up there in the first place. All that being said, we at Turion Space don't want to build a sustainable future in space at the cost of polluting Earth. For the first missions, we will drag the debris down to burn up in Earth's atmosphere, but long term, we plan to utilize reusable launch vehicle upper stages (think Starship, Relativity, and others) to bring stuff back down for us. It's a bit of an essay for a simple question, but regardless of how polluting it may be, with fully reusable launch vehicles coming online in the same time frame we are looking at performing missions, we will use those to bring stuff back down.
