NASA stands for National Aeronautics and Space Administration. It is the United States government agency responsible for space exploration, aeronautics, and scientific research.

NASA (National Aeronautics and Space Administration) is an independent agency of the U.S. federal government responsible for civilian space exploration, aeronautics, and aerospace research. It was established on July 29, 1958, by the National Aeronautics and Space Act, replacing its predecessor, the National Advisory Committee for Aeronautics (NACA).
