Swarm is the fifth Earth Explorer mission approved in ESA's Living Planet Programme, and was successfully launched on 22 November 2013.

As part of the Third Party Missions programme, the e-POP instrument of the Canadian Space Agency's CASSIOPE mission joined the constellation in February 2018.

The research objectives of the Swarm mission is to provide the best-ever survey of the geomagnetic field and its temporal evolution as well as the electric field in the atmosphere using a constellation of 3 identical satellites carrying sophisticated magnetometers and electric field instruments.

Tug-of-war drives magnetic north sprint

15 May 2019

As far as we know, Earth's magnetic north has always wandered, but it has recently gained new momentum and is making a dash towards Siberia at a pace not seen before. While this has some practical implications, scientists believe that this sprint is being caused by tussling magnetic blobs deep below our feet.

Happy 6th birthday Swarm

22 November 2019

On 22 November 2013 the three ESA Swarm spacecraft were launched, and started their mission to deepen our understanding of Earth's magnetic field from the Core to the Sun. After 6 years and more than 30,000 revolutions around our planet, the Swarm triplets are in excellent health providing groundbreaking new insight into Earth's magnetic field and near-Earth space environment helping us find answers to fundamental questions about our planet.
