The mission

Cluster is a constellation of four spacecraft investigating the interaction between the Sun and Earth’s magnetosphere in unparalleled detail. The magnetosphere is our shield against the charged gas that carries particles and magnetic fields outwards from the Sun.

Launch: 16 July and 9 August 2000
Observes: solar wind, magnetosphere
Orbit: elliptical around Earth’s poles, a few hundred to 125 000 km altitude
Spacecraft names: Rumba, Salsa, Samba and Tango

11 instruments
4 spacecraft
2 decades of operation
