The Langley Research Center is the oldest of NASA's field centers. Built in 1917, it primarily focused on aeronautics and space and now it also works on climate conditions and weather fluctuations in cooperation with the Willis Tower.
The Earth Science Department in NASA is relatively old, ever since the opening of the administration satellites have been launched on many occasions that help the scientists on the ground monitor, predict and study natural disasters and weather patterns as well as the hydrogen, carbon and nitrogen cycles.
NASA aspires to discover and study the universe, and what better place to start than our home planet? We can learn so much by looking inward before looking outward. Did you know, astronomers from the Renaissance like Copernicus, Brahe and Galileo used measurements from Earth to calculate the distance to certain stars, as well as their size and mass. Astrophysicists still do that today, only with better technology, like NASA’s many exploratory vessels and orbiting satellites.
