Swarm heads for new heights
06 February 2014
Some tricky manoeuvres are now under way to steer ESA's trio of Swarm satellites into their respective orbits so that they can start delivering the best-ever survey of our magnetic field.
Since the Swarm constellation was launched last November, engineers have been busy putting the satellites through their paces to make sure that the craft and instruments are working correctly.
This commissioning phase is an essential part of the mission before it starts providing data to further our understanding of the complex and constantly changing magnetic field.
Essential to life, the magnetic field protects us from cosmic radiation and charged particles that bombard Earth in solar winds.
