A group of participants from several U.S. agencies took part in a first-of-its-kind exercise that tested their preparedness for a severe solar storm, revealing major cracks in scientists’ ability to forecast space weather—which could put crucial systems at risk.
The Space Weather Operations, Research, and Mitigation (SWORM) task force, an inter-agency group that includes the National Ocean and Atmospheric Administration (NOAA) and the Department of Homeland Security (DHS), organized a space weather exercise aimed at better understanding the U.S. government’s preparedness for an impending solar storm. The results were recently published in a report, which highlighted significant limitations in space weather forecasting.
The exercise was held from May 8 to 9, 2024, at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and at a Federal Emergency Management Agency (FEMA) site in Denver, Colorado. The space weather scenario was organized into four modules involving a series of solar events that resulted in adverse effects on our systems on Earth and in space. The effects included radio communication blackout, loss of GPS functionality, power outages, intense radiation exposure for astronauts and satellites, and an inability to track and communicate with orbiting satellites.
