O marks the spot for magnetic reconnection 10 April 2017 ESA's Cluster mission is challenging the current view of magnetic reconnection – the breaking and immediate rearrangement of magnetic field lines in the collision of two plasma flows. Read more
Cluster is currently investigating the Earth's magnetic environment and its interaction with the solar wind in three dimensions. Science output from Cluster greatly advances our knowledge of space plasma physics, space weather and the Sun-Earth connection and has been key in improving the modeling of the magnetosphere and understanding its various physical processes.
Two-year extensions confirmed for ESA's science missions 22 November 2016 ESA's Science Programme Committee (SPC) has today confirmed two-year mission extensions for nine scientific missions in which the Agency is participating. This secures their operations until the end of 2018. Read more
The curious case of Earth's leaking atmosphere 07 July 2016 Earth's atmosphere is leaking. Every day, around 90 tonnes of material escapes from our planet's upper atmosphere and streams out into space. Although missions such as ESA's Cluster fleet have long been investigating this leakage, there are still many open questions. Read more
Cluster solves the mystery of equatorial noise 14 July 2015 ESA's Cluster mission has solved a mystery which puzzled scientists for almost half a century. Data sent back by two of the spacecraft have revealed for the first time the physical mechanism behind the generation of "noisy" waves in near-Earth space. Read more
Seven ESA satellites team up to explore Earth's magnetic field 01 July 2015 Cluster and Swarm find evidence of strikingly similar phenomena at different altitudes for the first time, showing a link between Earth's ionosphere and magnetosphere. Read more
