Description

ESA’s Swarm mission is dedicated to identifying and measuring precisely the different magnetic signals that make up Earth’s magnetic field. Generated largely from deep within the planet, the magnetic field can be thought of as a huge bubble, protecting us from cosmic radiation and charged particles that bombard Earth in solar winds.
