      There are but it’s difficult to match the power of a nuke’s EMP if set off 200km above the surface. It deforms the Earth’s magnetic field, resulting in a very quick induced current from the initial deformation, and a slower one that wrecks power stations at the ends of long power lines as it slowly returns to equilibrium. There’s another surge mixed in there, too, though I don’t recall the specific mechanism that causes it, though it’s similar to a lightning strike’s effect on electronics and could be prevented with a surge protector, if the first one hadn’t already destroyed it.

      That’s what I think this is really about. Not disabling satellites (though some would be), but EMPing the entire hemisphere when the grid is absolutely not capable of handling that. Imagine one of those going off Jan 6 2025. Even if government buildings are hardened against EMP (could go either way I suppose), video of what goes on would only get out if a coup fails, and even then only after the fact once the grid has been re-established and who knows what happens in every single city when the trucks can’t bring food in because their electronics are all fried.

        I dunno, what you are talking about doesn’t sound new. Just put a nuke on a regular satellite. They already fly in that space. Would it even give off enough radiation to be detected?
