What is a good job if you like outer-space?

sounds like you are on the right track. Make sure you study really hard and take as much math that you can especially advanced courses also important are chemistry, physics, biology, engineering, and computer sciences of all kinds. to be an astronaut you should first become a pilot. If thats the direction you are headed than along with all the other stuff you should look into the air force space program (it is even bigger than NASA) good luck
