NASA (the National Aeronautics and Space Administration),
established in 1958, is the United States agency of scientific
research, technological development, and exploration in space. Its
vision since its inception has been 'to reach for new heights and
reveal the unknown so that what we do and learn will benefit all
humankind.' Responsible not only for landing the first men on the
moon in 1969, NASA's technological research has led to the
development of the first weather and communications satellites,
moer than 130 flights within 30 years of space shuttle missions,
the landing of rovers on the Mars surface, as well as the
establishment with 16 other nations of an International Space
Station in 2000.
Since the retirement of the space shuttle missions in 2011, NASA has continued its scientific research with several aims, most notably to land humans on Mars and to launch the Next Generation Air Transportation System by 2025, a program to design aircrafts that are more fuel-efficient and environmentally responsible.
