Swarm: to unravel Earth’s inner secrets

Swarm is a constellation of three satellites to measure precisely the magnetic signals that stem from Earth’s core, mantle, crust and oceans, as well as its ionosphere and magnetosphere. The geomagnetic field models resulting from the mission will provide new insights into Earth’s interior. These data along with measurements of atmospheric conditions around the orbiting satellites will further studies into Earth’s weakening magnetic shield, space weather and radiation hazards.
