Dead satellites are filling space with trash. That could affect Earth’s magnetic field | Sierra Solter

Our ozone is pennies thick – and soon we’ll put at least an Eiffel Tower’s worth of metallic ash into the ionosphere every year

Opinion piece by Sierra Solter, “a plasma physicist, engineer, and inventor who studies the intersection of heliophysics and aerospace”. Relevant quote:

Upon investigating just how much dust in the form of satellite and rocket debris the space industry has dumped into the ionosphere during re-entry, I was alarmed to find that it is currently multiple Eiffel Tower’s worth of metallic ash. I wouldn’t have even been able to calculate that at all without a scientist’s personally run website. Our ozone is mere pennies thick, and soon we will be putting at least an Eiffel Tower’s worth of metallic ash a year directly into the ionosphere. And all of that will stay there, indefinitely.

How could we possibly think that burning trash in our atmosphere 24/7 is going to be fine?

    Meteorites carry plenty of metals, including aluminium and other highly conductive materials. Also, aluminium does not get anywhere near superconductive in space temps, which the author claims happens. That alone should tell you how much credence to give the rest of their claims.
