Gregory's Server@sundogplanets @firn To me, it seems the environmental cost of launching the satellites into orbit and the waste associated with all the booster rockets and such far outweigh whatever environmental impact of the satellites themselves burning up.

 @djuuss @mikemccaffrey @firn Just a quick reminder: I am studying this, I actually know what the numbers are. The pollution from planned reentries is indeed worse than the pollution from launches. And it's already being measured: https://www.pnas.org/doi/full/10.1073/pnas.2313374120 @sundogplanets @mikemccaffrey @firn What's the 'oh my gosh' tl;dr? i'm not a scientist reader @sundogplanets @mikemccaffrey @firn so far i'm getting: there's a thin mist of metal in the upper atmosphere already that is precipitating slowly like a snowglobe. Lead wise, don't worry about it, because the US is still pumping out 700 tonnes of lead from chimneys a year (???!What?) And you're expecting the metal clouds to descend on the poles with.. unknown effects. |
@mikemccaffrey @sundogplanets @firn depends what it's doing to the ozone layer. It could be very concerning indeed, theoretically much worse.
