Why is underwater training such an important aspect of astronaut training? I have heard that NASA astronauts actually train inside a 40-feet deep pool. How does it help when they go on space missions, as there is no such huge water bodies in space.

My son is 16. He is very interested in science especially physics. In fact he has consistently scored high in science. I wanted to encourage him and have him pursue his ambition with more focus and drive. He wants to take up space studies when he grows up. However, I don’t know if the tuitions and science exhibitions he has been to are helping him reach that advanced level. Any ideas on how to channelize his interest to an advanced level?
