The Space Act of 1958 is a U.S. law that established the National Aeronautics and Space Administration (NASA) and outlined its purpose to engage in civilian space exploration and research. This act was a direct response to the Soviet Union's successful launch of Sputnik, marking the beginning of a competitive space race between the two superpowers. The act aimed to ensure that the United States would be a leader in space technology and science, fostering advancements in research, satellite development, and aerospace technology.
