Document signed: "J. A. Van Allen", 1 page, 6¼x9¼. Document titled "Explorer-I and Jupiter-C: the First United States Satellite and Space Launch Vehicle", issued by the Department of Astrophysics, National Air and Space Museum, Smithsonian Institution. James Van Allen (1914-2006) isbest known for his work in magnetospheric physics. He developed proposals for the launch of a scientific satellite as part of the research program conducted during the International Geophysical Year of 1957-1958. The idea for the IGY, in fact, emerged from a discussion in his living room in 1950. His Explorer spacecraft, launched in 1958, returned important scientific data about the radiation belts circling the Earth, named the Van Allen Belts in his honor. Van Allen chaired the group of space scientists who recommended in 1958 that the US commit itself to a manned landing on the moon within ten years. Later, however, he came to feel that unmanned spacecraft could acquire more scientific information at a lower cost. Fine condition.
