NASA:- National Aeronautic and Space Administration
NASA stands for National Aeronautics and Space Administration. It is an independent agency of the US government which is responsible for the civilian space program, aeronautics, and aerospace research. It was formed on July 29, 1958, with headquarters in Washington DC. It was established by President Dwight D Eisen however with a distinctly civilian orientation encouraging peaceful applications in space science. Most of US space exploration efforts, including the Apollo Moon landing missions, the Skylab space station and later the Space Shuttle, have been led by NASA. It supports the International Space Shuttle and oversees the development of the Orion Multi-purpose Crew Vehicles, Space Launch System and Commercial Crew Vehicles. It is also responsible for the Launch Services Program which oversees the launch operations and counts down management for unmanned NASA launches. A few of the major NASA directives are to land people on the moon, build space shuttles and to build a large space station. These were intervened by the science advisory, political, funding, and public interest and synergized into various waves often heavily swayed by technical, funding and worldwide events.
