The mission

ESA’s three-satellite Swarm mission is dedicated to unravelling one of the most mysterious aspects of our planet: the magnetic field. Although invisible, the magnetic field and electric currents in and around Earth generate complex forces that have immeasurable impact on everyday life. By analysing the different characteristics of the observed field, Swarm will lead to new insight into many natural processes, from those occurring deep inside the planet to weather in space caused by solar activity.

The launch

Date: 22 November 2013
Site: Plesetsk Cosmodrome, Russia
Launcher: Rockot
