Giulio Costanzi (1875–1965), Officer of the ITAF Engineers Corps, was a pioneer of space studies in Italy. In 1914 he wrote a paper on space navigation and nuclear propulsion that is regarded as the first Italian contribution to space flights on record.
Costanzi started his career as a civil engineer, then entered the Army in the Artillery Corps. From 1911 he served as an officer in the Specialized Engineers Corps, the first nucleus of the future Italian Air Force. The Corps manned aerostatic balloons and airships and was equipped with a range of laboratories planned by Gaetano Arturo Crocco, plus a wind tunnel. In WW I Costanzi headed a squadron of reconnaissance aircraft and in 1923 was put in charge of an experimental section of the Italian Air Force. In 1928 he left the service as a General, was named member of the State Council and from 1938 to 1945 served as president of the Italian Air Registry, the equivalent of the US Federal Aviation Agency.
The first Italian contribution to Space Exploration
In 1914, in a specialized magazine, Costanzi published an article on navigation in space suggesting nuclear propulsion to propel spaceships. It is the first scientific contribution by an Italian to space flight, anticipating many problems related to exploration of outer space. “After the conquest of the air through aircraft, it is high time to abandon Earth and found new colonies in space” he writes, and then expounds the problem of powering spaceships in the void, without any support from the atmosphere, as in the case of airplanes. He advocates space travel on the basis of action-reaction dynamics, plans a flight Earth-Moon and to overcome the force of gravity he postulates the need for a new source of power. He identifies this source with radio and its yet unknown characteristics. In his article, Costanzi describes what would be the dangers and sensations experienced by an astronaut, such as suffering extreme heat, poisonous radiations, G-acceleration and weightlessness, the latter resulting in a feeling of falling. He concludes affirming hopefully that ‘the obstacles to this last dream are not beyond human reasoning, for the time being we are bound only by the lack of appropriate technology”.
