Tiny satellite could give us 3 hours of solar storm warning

AI Insight

A UK-built miniature magnetometer called MAGIC will be deployed in deep space as part of ESA's HENON CubeSat mission to provide early warnings of solar storms. The instrument aims to extend the current warning time from approximately 15 minutes to 3 hours before geomagnetic disturbances reach Earth. The mission is scheduled to launch in early 2027.


Extended warning times for solar storms would provide critical additional time for power grid operators, satellite operators, and aviation authorities to implement protective measures against potentially damaging space weather events. This could help prevent widespread technological disruptions and reduce economic losses associated with geomagnetic storms.

Space weather warnings could be received hours before Earth is hit rather than minutes with the help of a miniature UK-built instrument soon to be stationed in deep space. MAGIC (MAGnetometer from Imperial College) is part of the European Space Agency’s Heliospheric Pioneer for Solar and Interplanetary Threats Defense (HENON) CubeSat mission, which is scheduled for launch in early 2027.
