ESA Swarm satellites map earth core
AFBytes Brief
Three ESA Swarm satellites launched in 2013 continue to collect data on variations in Earth's magnetic field generated by the outer core. The measurements provide new constraints on core dynamics and flow patterns.
Why this matters
Improved understanding of Earth's magnetic field supports navigation systems and infrastructure protection from geomagnetic storms.
