Reflecting on Radiation Belt Discoveries, 60 Years After First U.S. Satellite Launched into Space

NASA/Van Allen Probes/Goddard Space Flight Center
Two giant swaths of radiation, known as the Van Allen Belts, surrounding Earth were discovered in 1958. The radiation is shown here in yellow, with green representing the spaces between the belts.

60 years ago this week, the first U.S. satellite, Explorer One, launched into space. An instrument on the satellite, designed and built by University of Iowa physicist James Van Allen, discovered radiation belts around the Earth, a stunning discovery that made headlines worldwide.

On this River to River segment, Ben Kieffer talks with University of Iowa astrophysicist Allison Jaynes about how Van Allen’s discovery helps scientists today discover the dangerous areas for satellites and astronauts traveling in the near-Earth environment.

Other interviews during this segment include a conversation with IPR statehouse correspondent Joyce Russell and AP correspondent, Ryan Foley.
