The year 1953 saw the rockoon join the stable of sounding rockets capable of reaching beyond the 100 kilometres (62 mi) boundary of space (as defined by the World Air Sports Federation).[1] Employed by both the University of Iowa and the Naval Research Laboratory, 22 total were launched from the decks of the USS Staten Island and the USCGC Eastwind this year. All branches of the United States military continued their program of Aerobee sounding rocket launches, a total of 23 were launched throughout 1953. The Soviet Union launched no sounding rockets in 1953; however, the Soviet Union did conduct several series of missile test launches.
Both the United States and the Union of Soviet Socialist Republics continued their development of ballistic missiles: the United States Air Force with its Atlas ICBM, the United States Army with its Redstone SRBM, the Soviet OKB-1 with its R-5 IRBM, and Soviet Factory 586 with its R-12 IRBM. None entered active service during 1953.
The first meeting of the Comité Speciale de l'Année Géophysique Internationale (CSAGI), a special committee of the International Council of Scientific Unions (ICSU), began preliminary coordination of the International Geophysical Year (IGY), scheduled for 1957–58.
