31/01/1958 First U.S. Satellite Discovers Van Allen Belt

A Van Allen radiation belt is a zone of energetic charged particles, which are captured by and held around a planet by that planet's magnetic field. Existence of such belt was suggested before the Space Age. But the proof came with American satellites Explorer 1 and Explorer 3 and the team of James Van Allen at the University of Iowa.
