The National Aeronautics and Space Administration (NASA) is an agency of the United States federal government responsible for the civilian space program as well as aeronautics and aerospace research. NASA’s mission is to pioneer the future in space exploration, scientific discovery and aeronautics research.

NASA was established in 1958. Since that time it has conducted many manned and unmanned spaceflight programs, including the Apollo moon-landing missions, the Skylab space station, and later the Space Shuttle. Currently, NASA is supporting the International Space Station and is overseeing the development of the Orion Multi-Purpose Crew Vehicle, the Space Launch System and Commercial Crew vehicles. The agency is also responsible for the Launch Services Program (LSP), which provides oversight of launch operations and countdown management for unmanned NASA launches.
