    Earth's magnetosphere

    Date: 11 Mar 2010
    Satellite: Cluster

    Illustration of the Earth's magnetosphere (shown in blue). The Van Allen outer and inner radiation belts are located within the magnetosphere. They have been represented as two tori around Earth (coloured in orange). The Van Allen radiation belts were discovered as a result of an experiment designed by James Van Allen that was carried onboard the first US satellite, Explorer 1, launched in 1958.
