Sputniks,explorers and propaganda: The discovery of the earth's radiation belts 1

Abstract

The most important scientific discovery of the early space era ‐ the 1958 discovery of the radiation belts of the Earth ‐ was made in the context of Cold War rivalry between the USSR and the USA. The paper uses previously unavailable archival records to reconstruct the relative contributions of American and Soviet researchers and their interations during the process of discovery. The former discovered what is now known as the inner radiation belt, while the latter observed the outer radiation belt and gradually came to realize the existence of two distinctively different zones of radiation. The uses of science for the purposes of Cold War political propaganda affected the behavior of scientists and led to the misrepresentation of the events in mass media.
