On July 29, 1958, the National Aeronautics and Space Administration (NASA) was created by President Dwight Eisenhower. NASA was created largely as a response to Sputnik, a satellite successfully launched by the Soviet Union in 1957. Sputnik and NASA launched the “Space Race,” in which the United States and the Soviet Union competed to send the first and most satellites and people into outer space.

Today, NASA has four directorates: Aeronautics research, whose mission is to “enable a safer, more secure, efficient, and environmentally friendly air transportation system;” human exploration and operation, whose mission is to “operate the International Space Station and prepare for human exploration beyond low Earth orbit;” science, whose mission is to explore “the Earth-Sun system, our own solar system, and the universe beyond;” and space technology, whose mission is to “develop the crosscutting, advanced and pioneering new technologies needed for current and future missions, benefiting the aerospace industry and other agencies, and addressing national needs.”
