Cluster Helps Solve Mysteries of Geomagnetic Storms

In a powerful example of combining multi-mission satellite data with computer simulations, scientists have used ESA's Cluster mission to reveal details about how electrons interact with waves in Earth's magnetic environment. This research helps explain the behaviour of particles during geomagnetic storms and has significant implications for our understanding of space weather, which is in turn necessary to help protect space technology from the potentially harmful effects of energetic particles generated during such storms.
