Minimize What is Swarm?
Web Content Image

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

The objective 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.

Yaw manoeuvre on Swarm Bravo

28 March 2017

We inform the Swarm users that a 20 degrees yaw manoeuvre was performed on Swarm Bravo from 20 March 08:01:02 UTC to 27 March 18:55:03 UTC. The purpose of the test was to increase the EFI TII temperature and consequently the outgassing rate of contaminants that cause TII image anomalies.

Swarm MAGx_LR_1B dataset (version 0501) has been extended

27 March 2017

With reference to the news published on 05 January 2017 we inform the Swarm users that the Swarm MAGx_LR_1B version 0501 has been extended for all Swarm spacecraft.

Issues in the Swarm Faceplate dataset at 16 Hz

15 March 2017

We inform the Swarm users that the Faceplate dataset at 16 Hz has the following caveats:

  • due to an initial misevaluation of the Faceplate area, an offset exists on the density. Users shall take into account that: Ne_true = 0.8 * Ne_data
  • due to a bug in computation, coordinates in the dataset are not correct. Users interested in precise geolocation are suggested to use the coordinates stored in the "Experimental 2 Hz product" and interpolate to 16 Hz.

Supersonic plasma jets discovered

23 March 2017

Information from ESA's magnetic field Swarm mission has led to the discovery of supersonic plasma jets high up in our atmosphere that can push temperatures up to almost 10,000°C.

Swarm detects asymmetry

22 March 2017

Strong electric currents in the upper atmosphere are known to vary according to the season, but ESA's Swarm mission has discovered that this seasonal variation is not the same in the north and south polar regions.
