NASA's History & Work

Pankajnath Tiwari :-
NASA, the National Aeronautics and Space Administration, is the United States government agency responsible for the nation’s civilian space program and for aeronautics and aerospace research. Here’s an overview of NASA’s history and its work:


NASA was established on July 29, 1958, as a response to the Soviet Union’s successful launch of the satellite Sputnik, which triggered the Space Race between the US and the USSR during the Cold War.

The agency was created through the National Aeronautics and Space Act, signed by President Dwight D. Eisenhower.

NASA’s predecessor was the National Advisory Committee for Aeronautics (NACA), which conducted aeronautical research from 1915 to 1958.

NASA’s first major achievement was the successful launch of the first American satellite, Explorer 1, in January 1958.

In 1961, NASA initiated the Apollo program with the goal of landing humans on the Moon. This culminated in the historic Apollo 11 mission in 1969, when Neil Armstrong and Buzz Aldrin became the first two humans to walk on the lunar surface.

After the Moon landings, NASA shifted its focus to the development of the Space Shuttle, a reusable spacecraft that operated from 1981 to 2011.

Over the years, NASA has been involved in numerous robotic missions, including the exploration of other planets, the study of Earth, and the observation of distant galaxies through space telescopes like the Hubble Space Telescope and the James Webb Space Telescope (set to launch in 2021).
