What Does an Astronaut Do?
Did you know that the word "astronaut" comes from a Greek word meaning "space sailor?" Astronauts are scientists who are trained to travel into outer space in spacecrafts.
Astronauts help other scientists by gathering information about the environment in space and on other planets, and by observing the earth from a great distance. They study the Sun and how it affects Earth, and work with satellites in space to help to predict earthquakes and tsunamis.
An astronaut’s salary ranges between $40,000 and $80,000 per year
