In 1952, several branches of the United States' military, often in partnership with civilian organizations, continued their programs of sounding rocket research beyond the 100 kilometres (62 mi) boundary of space (as defined by the World Air Sports Federation)[1] using the Aerobee rocket. The University of Iowa launched its first series of rockoon flights, demonstrating the validity of the balloon-launched rocket, a comparatively inexpensive way to explore the upper atmosphere. The launch of Viking 9 at the end of the year to an altitude of 135 mi (217 km), by the Naval Research Laboratory team under the management of Milton Rosen, represented the pinnacle of contemporary operational rocket design.
The same year, groundwork was laid for the launch of the first artificial satellite when, in October, the General Assembly of the International Council of Scientific Unions (ICSU) scheduled the International Geophysical Year for 1957–58. This scientific endeavor would involve 67 nations in a global investigation of physical phenomena, on the ground and in space.
No new models of ballistic missile were added to the arsenals of either the United States or the Soviet Union in 1952. However, work continued on large rocket development, particularly the US Army's Redstone and the Soviet R-5 missile. Both the R-1 and R-2 missiles had operational test runs during the year.
