Swarm trio becomes a quartet
22 February 2018
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.

Measurements of atmospheric ozone from the Copernicus Sentinel-5P satellite are now being used in daily forecasts of air quality.
Launched in October 2017, Copernicus Sentinel-5P – short for Sentinel-5 Precursor – is the first Copernicus satellite dedicated to monitoring our atmosphere.
