NASA is the United States National Aeronautics and Space Administration. It is the agency responsible for the nation's civilian space program and for aeronautics and aerospace research. NASA was established in 1958, following the launch of the Soviet Union's Sputnik satellite, which marked the beginning of the space race between the two superpowers.
NASA has a number of key objectives, including exploring the solar system, studying Earth from space, and conducting research to advance the state of aerospace technology. The agency has achieved a number of notable milestones, including the first manned moon landing in 1969, and the development of the International Space Station, which has been continuously inhabited by astronauts since 2000. NASA also conducts a number of research projects, including the study of dark energy and the search for exoplanets.
