PARIS (ESA PR) — It’s the first mission of its kind, set to monitor our active and unpredictable Sun and help protect us from its violent outbursts – and it has a new name.

Once known as “Lagrange,” ESA’s upcoming space weather mission needed a new name that would reflect its vital role: helping to protect Earth’s infrastructure, satellites, inhabitants and space explorers from unpredictable but violent solar events like solar flares and ‘coronal mass ejections’.

Swarm and Cluster Get to the Bottom of Geomagnetic Storms
The magnetic field and electric currents in and around Earth generate complex forces that have immeasurable impact on every day life. The field can be thought of as a huge bubble, protecting us from cosmic radiation and charged particles that bombard Earth in solar winds. (Credit: ESA/ATG medialab)

PARIS (ESA PR) — The notion of living in a bubble is usually associated with negative connotations, but all life on Earth is dependent on the safe bubble created by our magnetic field. Understanding how the field is generated, how it protects us and how it sometimes gives way to charged particles from the solar wind is not just a matter of scientific interest, but also a matter of safety. Using information from ESA’s Cluster and Swarm missions along with measurements from the ground, scientists have, for the first time, been able to confirm that curiously named bursty bulk flows are directly connected to abrupt changes in the magnetic field near Earth’s surface, which can cause damage to pipelines and electrical power lines.
