Starlink satellites are designed to completely burn up upon reentry, but every few months there are news reports about space debris impacting Earth.

      These satellites are designed to last about five years. A 550-pound satellite will release about 66 pounds of aluminum oxide nanoparticles during reentry. Starlink’s satellites have grown heavier over time, with the latest version weighing in at about 2,760 pounds.

      The aluminum will mostly be released between 30 and 50 miles above the Earth’s surface but will then drift down to the ozone layer, which would take about 30 years. We’re already seeing these effects – satellites burning up in 2022 caused a 29.5% increase of aluminum in the atmosphere above the natural level – but the researchers said it will only get worse.

      mmm, gross.

      From what I read about the whole thing back when I was sort of interested, all the satellites have to be inserted into a VERY low earth orbit to be operable. So, barring numbers, they’ll be falling through the sky constantly simply because the design is short-lived by its very nature. Makes sense why Elon would be into it so much. If he can get governments to invest in it, it would be a constant revenue stream. A money pit, if you will.

      It’s US media. Even the puff pieces need to have a China bad line here and there.
