Swarm

ESA's magnetic field mission Swarm. A European Space Agency mission to investigate the Earth's magnetic field in unprecedented detail is due to be launched later this year. Without our planets protective magnetic field, life on our planet would struggle to survive. The Swarm mission consisting of three identical satellites will be used to study all aspects of the Earth's magnetic field and assess whether it is weakening. This report outlines the science of the mission and includes interviews with a project scientist and project manager.

Swarm is a European Space Agency (ESA) mission to study the Earth's magnetic field. High-precision and high-resolution measurements of the strength, direction and variations of the Earth's magnetic field, complemented by precise navigation, accelerometer and electric field measurements, will provide data essential for modelling the geomagnetic field and its interaction with other physical aspects of the Earth system. The results will offer a unique view of the inside of the Earth from space, enabling the composition and processes of the interior to be studied in detail and increase our knowledge of atmospheric processes and ocean circulation patterns that affect climate and weather.
