My wish is to be an astronaut when I grow up. Because astronauts can go to the universe, explore the mysteries of the universe and know what other planets are in space. Now I know the names of some planets, such as Earth, Moon, Sun, Mercury, Mars and Venus. ...
I want to be an astronaut because the teacher said in class that there are still many unsolved mysteries about the sun and the moon waiting for us to explore. I am interested in some questions mentioned in the article, such as: Is the moon older or younger than the earth? Is the volcanic activity of the moon later or earlier than that of the earth? Is the dust on the moon really bactericidal ... I think, when I grow up, I must explore the answers to these questions, and I will explore all the secrets of the universe. I think this is what astronauts should do. In addition, I also want to write some articles about the mysteries of the universe for children, so that the next generation of children are also interested in the universe, become astronauts, explore the secrets we have not discovered, and let them be passed down from generation to generation.
Now I will study hard and try to make my wish come true as soon as possible.
