NASA - National Aeronautics and Space Administration

NASA Headquarters, in Washington, provides overall guidance and direction to the agency, under the leadership of the Administrator. Ten field centers and a variety of installations around the country conduct the day-to-day work in laboratories, on air fields, in wind tunnels, and in control rooms. Together, this skilled, diverse group of scientists, engineers, managers, and support personnel share the Vision, Mission, and Values that are NASA.

To implement NASA’s Mission, NASA Headquarters is organized into three principal organizations called Mission Directorates:

Aeronautics: Pioneers and proves new flight technologies that improve our ability to explore and which have practical applications on Earth.

Human Exploration and Operations: Focuses on International Space Station operations and human exploration beyond low Earth orbit.

Science: Explores the Earth, moon, Mars, and beyond; charts the best route of discovery; and reaps the benefits of Earth and space exploration for society.
