Mission overview & Operations timeline - Cluster Science Archive
Cluster is the first constellation of four spacecraft flying in formation around Earth.
Since 2000, they relay the most detailed information about how the solar wind affects our planet in three dimensions. The solar wind (the perpetual stream of subatomic particles expelled by the Sun) can damage communications satellites and power stations on Earth.
Science output from Cluster is a leap forward in our knowledge of space plasma physics, science behind space weather and the Sun-Earth connection. It has been key in improving the modelling of the magnetosphere and understanding its various physical processes.

Timeline of the regions crossed
Various separations of the Cluster satellites constellation have been performed to target the numerous scientific objectives of the mission. Please find below a timeline of these separations together with their main targeted space regions (see also http://sci.esa.int/cluster/23160-constellation-geometry-over-time/).
