Swarm trio becomes a quartet

Quote
With the aim of making the best possible use of existing satellites, ESA and Canada have made a deal that turns Swarm into a four-satellite mission to shed even more light on space weather and features such as the aurora borealis.

In orbit since 2013, ESA’s three identical Swarm satellites have been returning a wealth of information about how our magnetic field is generated and how it protects us from dangerous electrically charged atomic particles in the solar wind.

Canada’s Cassiope satellite carries three instrument packages, one of which is e-POP.  It delivers information on space weather which complements that provided by Swarm. Therefore, the mission teams began looking into how they could work together to make the most of the two missions.

To make life easier, it also just so happens that Cassiope’s orbit is ideal to improve Swarm’s readings.

And now, thanks to this international cooperation and formalised through ESA’s Third Party Mission programme, e-POP has effectively become a fourth element of the Swarm mission. It joins Swarm’s Alpha, Bravo and Charlie satellites as Echo.

Magnetic north on the move

Driven largely by the churning of fluid in Earth’s core, which generates the magnetic field, the magnetic north pole has always drifted. Around 50 years ago, the pole was ambling along at around 15 km a year, but now it is charging ahead at around 55 km a year, leaving the Canadian Arctic heading towards Siberia.
