A cutaway picture of Explorer-1 [Prime], which at 10 cm x 10 cm x 10 cm (4 1/2 inches), and only 1 kg (2.2 lbs.), is  1/40th the volume of the original Explorer 1 and 1/14th the total weight.

            The Van Allen Radiation belts were discovered by the Explorer 1 spacecraft. They are belts of radiation that are found in intervals around the earth. They can change depending upon the sun's activity and the sunspot cycle, and are related to the Aurora Borealis.
