  • This was thoroughly torn apart in another thread.

    Some of the top results:

    “Meteors only contain trace amounts of highly conductive metals” Solter-Hunt said. “Satellites, on the other hand, are basically entirely made of superconductive metals.” 7% of meteorites that strike Earth are either entirely metal or partially metal. Additionally, the metallic ones are usually larger than the stony ones. I’m sure a PHD knows this, so I’m guessing the author of the article didn’t include some context.


    The link in that passage says that the newer, bigger Starlink satellites are only 800 kg in total mass. I’m not entirely sure how an 800kg object leaves 1300+ kg of “charged dust” upon re-entry.


    “Satellites are mostly made of aluminum and aluminum is a superconductor,” Solter-Hunt said. "Superconductors are used for blocking, distorting or shielding of magnetic fields.

    “Though 100 Kelvin is still pretty chilly – that’s about -280 degrees Fahrenheit – this is an enormous increase compared to bulk aluminum metal, which turns superconductive only near 1 Kelvin (-457 degrees Fahrenheit)”

    It doesn’t get that cold in LEO or GEO, so I’m not sure why the author of the paper is bringing that up. This paper and its author are looking more suspect by the minute.
