The National Aeronautics and Space Administration is America’s civil space program and the global leader in space exploration. The agency has a diverse workforce of just under 18,000 civil servants, and works with many more U.S. contractors, academia, and international and commercial partners to explore, discover, and expand knowledge for the benefit of humanity. With an annual budget of $23.2 billion in Fiscal Year 2021, which is less than 0.5% of the overall U.S. federal budget, NASA supports more than 312,000 jobs across the United States, generating more than $64.3 billion in total economic output (Fiscal Year 2019).
NASA was created largely in response to the Soviet launching of Sputnik in 1957. It was organized around the National Advisory Committee for Aeronautics (NACA), which had been created by Congress in 1915. NASA’s organization was well under way by the early years of Pres. John F. Kennedy’s administration when he proposed that the United States put a man on the Moon by the end of the 1960s. To that end, the Apollo program was designed, and in 1969 the U.S. astronaut Neil Armstrong became the first person on the Moon.Later, uncrewed programs—such as Viking, Mariner, Voyager, and Galileo—explored other bodies of the solar system.
NASA uses rockets to launch satellites and to send probes to other worlds. These rockets include the Atlas V, the Delta II, the Pegasus and Taurus. NASA also uses smaller "sounding rockets" for scientific research. These rockets go up and come back down, instead of flying into orbit.
Here are some famous rockets that NASA launched.
NASA’s Space Launch System will be the most powerful rocket we’ve ever built. When completed, SLS will enable astronauts to begin their journey to explore destinations far into the solar system.It replaced the Ares I and Ares V launch vehicles, which were cancelled along with the rest of the Constellation program.
The Saturn V was a rocket NASA built to send people to the moon. A Heavy Lift Vehicle, it was the most powerful rocket that had ever flown successfully.The Saturn V was used in the Apollo program in the 1960s and 1970s and was also used to launch the Skylab space station.The Saturn V rocket was 363 feet tall, about the height of a 36-story building, and 60 feet taller than the Statue of Liberty.
The Space Shuttle was a partially reusable low Earth orbital spacecraft system operated from 1981 to 2011 by the U.S. National Aeronautics and Space Administration (NASA) as part of the Space Shuttle program. Its official program name was Space Transportation System (STS), taken from a 1969 plan for a system of reusable spacecraft where it was the only item funded for development
