Threats from space aren’t always obvious, but statistically its only a matter of time before one of them happens. One of the most concerning for many space experts is a massive solar storm, like the one that literally lit telegraph paper on fire when it hit back in 1859. In the last 150 years our technology has improved by leaps and bounds, but that also means it's much more susceptible to damage if another event like the “Carrington Event”, as the storm in 1859 is called. Estimates for potential damage range into the trillions of dollars, with full economic recovery taking well over a decade if something isn’t done to mitigate the damage beforehand. As part of that preparedness, the European Space Agency (ESA) has started requiring the operational crew of new satellites, which would be on the frontlines of any solar storm catastrophe, to simulate how they would handle such an event, as described in a recent press release focused on one of those simulations.
