In May 2024, state and local government officials gathered at the Johns Hopkins University Applied Physics Laboratory (APL) in Maryland and FEMA headquarters in Denver, Colorado. Their mission? To assess the nation’s preparedness for a worst-case scenario solar superstorm—an event that could cause widespread disruption to critical infrastructure.
The two-day simulation included a visualization of a powerful solar event: a series of coronal mass ejections (CMEs) hurtling toward Earth. CMEs are massive bursts of magnetized plasma from the Sun’s corona that can reach our planet in a matter of days. When they do occur, they can severely disrupt Earth’s magnetic field, damage satellites, knock out power grids, disrupt GPS and radio communications, and even affect aviation and emergency services.
The results of the exercise, published in a new federal report, reveal a disturbing truth: The United States remains unprepared for such a large-scale space weather event.
🌐 Why this matters:
Modern society depends on vulnerable technologies: power grids, satellites, navigation systems, and communications can all fail.
High-risk sectors include aviation, emergency response, financial systems, and even water supplies.
Historical precedent: The Carrington Event of 1859, the most powerful solar storm on record, disrupted telegraph systems worldwide. A modern version could cause trillions in damage.
🧩 What's being done:
While progress continues — through better forecasting, stronger infrastructure, and interagency cooperation — experts say much more is needed. Public awareness and government investment must increase to reduce disaster risk.
