What is Swarm?
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.
Mission Operations News
We would like to inform Swarm users that from 12 December 2018, at 13:34:56 UTC and 18 December 2018, at 12:43:30 UTC, the attitude information of the Star Tracker instruments on board the Swarm Alpha and Charlie satellites, respectively, are provided at 2 Hz rate, instead of the previous 1 Hz.
The ESA Swarm Dissemination Server is now also hosting a mirror of the CASSIOPE/e-POP full data archive (past and current observations) in native format. These products are freely available under the /#CASSIOPE_e-POP directory by FTP/HTTPS anonymous browsing. Read a full description of the e-POP data set.
Mission Scientific Highlights
08 February 2019
Since it was first measured in 1831, we have known that the magnetic north is constantly on the move. However, its tendency to slowly roam has stepped up a pace recently – so much so that the World Magnetic Model has had to be updated urgently with the pole's new location, vital for navigation on smartphones, for example. ESA's magnetic field Swarm mission has been key for this update.

A team of researchers, supported under ESA's Basic Activities, has recently investigated a resourceful new method of monitoring space weather. They utilised the data from the Swarm and GOCE Earth Explorer missions, and from LISA Pathfinder to investigate whether platform magnetometer data could also be used for space weather diagnostics.

Swarm DISC has just released two new Invitations To Tender for the generation of new data products supporting the exploitation of the Swarm mission. Please visit the Swarm DISC ITT website for further information.

On 22 November 2018 the Swarm mission celebrated its 5th birthday. Our mission is still in good health and continues to collect ground-breaking data on the various components of the magnetic field and on the near-Earth environment and their dynamics.
