Peaceful nuclear explosion that was used to measure and then help model global circulations in the atmosphere by following the movements of fallout aerosols. After the Van Allen Belts surrounding Earth were published about in 1958, James Van Allen suggested that a nuclear detonation would be one way of probing the magnetic phenomenon, data obtained from the August 1958 Project Argus test shots, a high-altitude nuclear explosion investigation, were vital to the early understanding of Earth's magnetosphere. Soviet nuclear physicist and Nobel peace prize recipient Andrei Sakharov also proposed the idea that earthquakes could be mitigated and particle accelerators could be made by
