Fact Sheet

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.

Cluster's 20 years of studying Earth's magnetosphere
7 August 2020

Despite a nominal lifetime of two years, ESA's Cluster is now entering its third decade in space. This four-spacecraft mission has been revealing the secrets of Earth's magnetic environment since 2000 and, with 20 years of observations under its belt, is still enabling new discoveries as it explores our planet's relationship with the Sun.

Auroral substorms triggered by 'short circuiting' of plasma flows
31 July 2020

New research using data from multiple spacecraft, including ESA's Cluster mission, has revealed the cause behind the sudden brightening of the auroral oval before it breaks up into a substorm.

Iron is everywhere in Earth's vicinity, suggest two decades of Cluster data
19 March 2020

Using over 18 years of data from ESA's Cluster mission, scientists have mapped the heavy metals in the space surrounding Earth, finding an unexpected distribution and prevalence of iron and shedding light on the composition of our cosmic environment.

Earth's magnetic song recorded for the first time during a solar storm
18 November 2019

Data from ESA's Cluster mission has provided a recording of the eerie 'song' that Earth sings when it is hit by a solar storm.

Cluster and XMM-Newton pave the way for SMILE
27 August 2019The Solar wind-Magnetosphere-Ionosphere Link Explorer (SMILE) mission is still four years away from launch, but scientists are already using existing ESA satellites, such as the XMM-Newton X-ray observatory and the Cluster mission studying Earth's magnetosphere, to pave the way for this pioneering venture.
Windy with a chance of magnetic storms – space weather science with Cluster
8 November 2018Space weather is no abstract concept – it may happen in space, but its effects on Earth can be significant. To help better forecast these effects, ESA's Cluster mission, a quartet of spacecraft that was launched in 2000, is currently working to understand how our planet is connected to its magnetic environment, and unravelling the complex...
Understanding Earth: what the Cluster mission has taught us so far
8 February 2018As inhabitants of the third rock from the Sun, we have a vested interest in understanding our home planet and its environment. Among the flotilla of spacecraft that have been sent to investigate Earth from space are the four spacecraft of the Cluster mission.

Space missions return to science
2 April 2020

After a brief shutdown of science instruments and a period in 'safe standby', ESA's planetary missions are getting back to what they do best, gathering science data from around the Solar System.

ESA scales down science mission operations amid pandemic
24 March 2020

In response to the escalating coronavirus pandemic, ESA has decided to further reduce on-site personnel at its mission control centre in Darmstadt, Germany. The new adjustments require temporarily stopping instrument operation and data gathering on four Solar System missions: Cluster, ExoMars TGO, Mars Express and Solar Orbiter.
