Click for larger image The joint ESA-NASA Cluster II mission is to study, in three dimensions, the small-scale structures of the Earth's plasma environment. While the original Cluster mission was lost on June 4, 1996, due to an expolsion of the Ariane-5 test flight, the ESA's Science Program Committee approved on April 5, 1997 the reflight of the full mission by mid-2000.

The Cluster II mission consists of four identical spacecraft flying in formation between 19000 and 119000 km above the Earth. There, they will study the plasmas and fields of the magnetosphere and the solar wind in three dimensions. (From the ESA Cluster II site.)
