Solar Storm Blackout Could Cost the US $42 Billion Per Day

We live under a thick, protective atmosphere that is shielded by a powerful magnetic shield, called the magnetosphere — solar radiation isn’t a daily concern unless you’re an astronaut in orbit taking a spacewalk. But should the perfect (solar) storm hit, we could be looking at a lot of dead satellites and, potentially, vast power outages across nations or even continents.

Now, in a new study focusing on this economic fallout, researchers have put the financial cost on a severe solar storm should it knock out a large portion of the US power grid, and it turns out that most of the financial impact will be felt well beyond the blackout zone.
