@larsmb@mastodon.online @jwildeboer@social.wildeboer.net @davidgerard@circumstances.run EMP propagation obeys an inverse-square law, and satellites operate in a high radiation environment. Much more efficient to just dump a cloud of iron filings in a reciprocal orbit. (at 15.6km/s closing velocity, each grain has a rifle-bullet-adjacent amount of kinetic energy.)
