Mission Description Cluster is the first constellation of four scientific spacecraft to study the Earth-Sun connection in three dimensions. Cluster offers unique opportunities to investigate physical processes in near-Earth space. Those processes are essential to study and understand the effects of the Sun on the vast Earth’s environment that is a highly varying system both in time and space. The four Cluster spacecraft in a polar orbit are unique in their ability to obtain a three-dimensional picture of medium and large-scale plasma structures. The varying Cluster spacecraft formation from 3 km to a few tens of thousands kilometres along the orbit enables multi-point local measurements of different regions at different scales that cannot be done with any other space mission.
