NACA+and+NASA

NACA was started in 1915 as the National Advisory Committee for Aeronautics. In 1958, President Dwight D. Eisenhower put this program in charge of non-military space exploration. They then changed their name to NASA (National Aeronautics and Space Administration). NASA took charge of NACA's labs and the missile development complex in Huntsville, Alabama. They also built astronaut training facilities and flight control centers in Houston. On January 31, 1958, NASA launched the first American satellite. Its name was Explorer 1.

Then we started Project Mercury, to see if humans could survive in space. After Project Mercury, We started Project Gemini, to land people on the moon. On July 20, 1969, Neil Armstrong and Buzz Aldrin became the first men to walk on the moon. Since then, 10 other men have walked on the moon.

After The moon, NASA continued scientific research. They invented the space shuttle. A space shuttle can be used again and again. In 1997, NASA sent the Mars Pathfinder to explore Mars. In 2000, the International Space Station was established. This means that there will be permanent human existence in space.
