   @KimSJ @justafrog @mikeolson @floatybirb Their planned satellite lifetimes are 5 years, they're planning to burn up the whole freaking fleet of them and send up new ones (adding tons of metals to the upper atmosphere every day). And with each launch they add uncontrolled debris, and orbit gets denser.

   Deorbit times at 550km are something like decades (depending on how circular orbits are).
