The national aeronautics and space administration (NASA) is responsible for formulating and implementing the American space program and conducting aviation science and space science research. NASA is mainly engaged in the following four aspects:

1, aerodynamics: turbulence, airfoil, supersonic flight, etc.

2. Propulsion technology: combustion and fuel, noise and its propagation, computational fluid dynamics, research on turbine mechanical parts.

3. Materials and structures: composite materials, high-temperature materials, dynamic loads and aeroelasticity, structural analysis, etc.

4. Avionics and human factor engineering: guidance and navigation, avionics, flight management and simulation technology.

1 958101October1day, NASA was formally established to replace its predecessor, the National Aviation Advisory Committee. Major projects of NASA include Apollo moon landing program, Skylab space station, and later the space shuttle. NASA has successfully carried out many space missions, but the first thing people think of is "Apollo 1 1".

This mission sent humans to the moon for the first time in 1969. The astronauts on the mission were commander neil armstrong and lunar module pilot buzz aldrin. Armstrong became "the first man to land on the moon". After he set foot on the moon, he said, "This is a small step for individuals, but a big step for mankind", which has since become a well-known saying.

In the past 60 years, in addition to conquering the moon, NASA has also completed a "preliminary understanding" of the solar system, using space tools to visit all the planets and many dwarf planets, satellites, asteroids and comets in the solar system. Voyager 1 spacecraft has entered interstellar space, and Voyager 2 is heading for interstellar space. Spacecraft such as Cassini, Hubble and Kepler telescope also sent back a large number of pictures to the earth.

These exploration activities and photos have changed people's understanding of the universe and its formation. NASA will continue to explore the solar system in depth. At present, it is planned to explore Europa, and a series of new generation telescopes are under construction, including the James Webb space telescope, which will be launched as early as 202 1.
