NASA is an independent US government agency established in 1958 to research, develop spacecraft, conduct space exploration activities inside and outside the Earth's atmosphere, and NASA is an abbreviation to the National Aeronautics and Space Administration. It is founded as a reaction to the Soviet Union's launch of Sputnik in 1957.
During its first years of existence, NASA remained under the administration of President John F. Kennedy who suggested that the United States should send a man to the moon by the end of the sixties, and that is why Apollo program was designed, becoming the American astronaut Neil Armstrong the first man landed on the moon.

NASA has four main working offices to achieve its goals, as following:
- Aviation Science Research Office: This department specializes in research and development to provide safe and reliable aviation vehicles and systems.
- Office of Exploration Systems: These systems help develop techniques to support human exploration and robots for space.
- Office of Science: The work of this office is dedicated to exploring the Earth, the sun, the solar system and the universe through the missions proposed by NASA scientists in both the agency and the NASA Academy.
- Office of Space Operations: This office manages the launch of spacecraft, communications operations of all spacecraft in and out of the Earth's orbit.

NASA has begun work on human space travel programs such as Apollo, Mercury and NASA's Gemini have helped understand how to fly into space, resulting in the first human landing on the moon in 1969.
Satellites provided vast amounts of data on the Earth, which led to important information, useful to humans such as better understanding of weather. It is reported that NASA has helped develop and test a variety of advanced aircraft.
NASA's tests also helped engineers improve air transport, and their technology contributed to many activities used in everyday life, such as smoke exploration and even medical tests.
