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.

12 October 2016

With reference to the news published on 07 October 2016, we'd like to inform users that the Level 1B data of Swarm Charlie for 02/10/2016 and of Swarm Alpha for 03/10/2016 have been regenerated.

Problems with Swarm data production on 2 and 3 October 2016

07 October 2016

Due to a technical problem in the production chain, Level 1B data from Swarm Charlie for 2 October 2016 are currently not available, and Level 1B data from Swarm Alpha for 3 October 2016 are truncated from approximately 16:00 UTC. The gaps will be recovered as soon as possible.

Collision avoidance manoeuvre on Swarm Bravo on 23 August 2016

30 August 2016

An orbit collision manoeuvre of Swarm Bravo started on 23 August 2016 12:04:12z for a duration of 95s equivalent to 2cm/s. This manoeuvre has raised the orbit and therefore has been preceded and followed by a 180 degree slew.

Magnetic oceans and electric Earth

04 October 2016

Oceans might not be thought of as magnetic, but they make a tiny contribution to our planet's protective magnetic shield. Remarkably, ESA's Swarm satellites have not only measured this extremely faint field, but have also led to new discoveries about the electrical nature of inner Earth.
