help please?

ask NASA

It depends. Astronauts are more specialized now. You can be a pilot, doctor, physicist, geologist (Moon and mars coming up) , structural engineer or any one of a hundred other disciplines. Whatever field you choose, you need to apply yourself to it and become the best. Then you can talk to Nasa about working up top.

Astronauts are scientists. All sorts of scientists can be astronauts, but they are all scientists, so take science classes. Also, most astronauts have some military background, so physical fitness is a must.

Physics, biology, chemistry and the most advanced math you can find. Good luck!
