The International Astronautical Congress (IAC) is an annual meeting of the actors in the discipline of space science. It is hosted by one of the national society members of the International Astronautical Federation (IAF), with the support of the International Academy of Astronautics (IAA) and the International Institute of Space Law (IISL). It consists of plenary sessions, lectures and meetings. The IAC is attended by the agency heads and senior executives of the world's space agencies. As the Second World War came to an end, the United States and the Soviet Union held different and competing political worldviews. As the Cold War began to take shape, communication between the two countries became less frequent. Both countries turned their focus to achieving military superiority over the other. Six years after the Iron Curtain fell, the IAF was formed by scientists from all over Europe in the field of space research in order to collaborate once more. During the years of the Space Race, the IAF was one of the few forums where members of both East and West Europe could meet during the annual IAC.

Locations of past and future International Astronautical Congresses (IAC)
