The purpose of this paper will be showing the Ruth Gall activities to promote the space physics and cosmic rays research through the formation of physicsts, and centers as Outer Space Department. She had the idea of developing the scientific research and technology in Mexico.

Brazil's nuclear program from 1945 to 1955 was characterized by an initial rapprochement with the United States, Later, Brazil tried to diversify its technology exchange agreements by reaching out to France and West Germany. Alvaro Alberto was the responsible for the implementation of the Brazilian Nuclear Program in the 1940s and 1950s, included Nuclear Physics in the Curriculum of the Brazilian Naval Academy, where he was a professor. In 1951, as president of the National Research Council, he traveled to France.

That year, France was developing a program to locate its uranium deposits in its overseas territories. The French Atomic Energy Commission offered Álvaro Alberto to train Brazilian uranium engineers and prospectors.
In 1954, Brazil and West Germany worked together to develop a plan for electrification with nuclear energy, considering needs and possibilities, but this did not materialize.
