Aerospace Engineer Aerospace engineering is the main field of engineering that deals with air crafts and spacecraft. There are tow main types of aerospace engineering aeronautical and astronautical. Many aerospace engineers design air crafts, spacecrafts, satellites, and missiles. They also test prototypes to make sure they are functioning right. Most of the engineers work in manufacturing industries or the government. Few get to work at the International Space Station. Astronaut There are two main types of astronauts mission specialists and pilot. Mission specialists work with the pilots to launch satellites, maintain equipment, and conduct experiments. Their background must be in one of the following engineering, science, or medicine. Mission specialists can also act as educators to teach students who are considering joining the U.S. space program. Pilot astronauts are in charge of the crew, mission success, and the safety of the flight. Astronomer Astronomers use the law of physics and mathematics to learn about matter and energy in the universe, which includes sun, moon, stars, and galaxies. They use their knowledge to to solve problems dealing with navigation, spaceflight, and satellite communications. Most astronomers work at universities where they study or teach astronomy. Some are employed by companies like U.S. Naval Observatory, National Aeronautics, and NASA. Astronomers gather the data that comes from satellites and observatories to use to make a hypothesis or add to current ones. Astrophysicist An astrophysicist's job is to discover how the universe works, began, and evolved. They also search for life on other planets around other stars. Their current mission in NASA isncludes three of the Great Observations which were originally planned in the 1980s. The Great Observations include the Hubble Space Telescope, Fermi Gamma-ray Space Telescope, Chandra X-ray Observatory, and Spitzer Space Telescope. Meteorologist Meteorologists study the earth's atmosphere and objects that originate from the sky. They use scientific observations to explain and forecast the weather. Radars are used to send radio waves to bounce off particles from the atmosphere and a computer processes the dimensions of the cloud, precipitation, and the speed and direction the clouds are moving.
