The National Aeronautics and Space Administration is an independent agency of the U.S. federal government responsible for the United States' civil space program, as well as research in aeronautics and space. Headquartered in Washington, D.C., NASA operates ten field centers across the US and is organized into three mission directorates: Human Spaceflight, Research and Technology, and Science. Established in 1958 amid the Space Race, NASA succeeded the National Advisory Committee for Aeronautics to give the US space program a distinct civilian orientation focused on peaceful applications. Since then, it has led most American spaceflight programs, including Project Mercury, Project Gemini, the Apollo program, Skylab, the Space Shuttle, the International Space Station, and the ongoing multinational Artemis program. NASA maintains extensive ground and communications infrastructure, including the Deep Space Network and the Near Earth Network.
