CLUSTER II
Short Description:
ESA's Cluster II mission consisted of four identical spacecraft flying in a tetrahedral (triangular pyramid) formation between 25000 and 125000 km above the Earth. They studied the planet's magnetic field and electric surroundings in three dimensions. In particular, they looked at the effects of the solar wind, which buffets Earth's protective magnetosphere.
Each of the Cluster II spacecraft carried an identical set of 11 instruments. These are sensitive to electric and magnetic fields, various electric and magnetic waves, and to electrons and charged atoms.
The mission is a direct repeat of the original Cluster project lost during the explosion of the Ariane-5 demonstration flight in June 1996. Cluster II is based on the original mission, even using some of the original spare parts. Its scientific objectives also remain unchanged.
The names of the four: Rumba, Salsa, Samba and Tango.
