I’d like to be an astronaut too and I’m going into AeroE. I am very interested in aerospace and love learning about it - I’ve done rocketry and I love reading books about astronauts and spaceflight. Of course I know that being an astronaut is a lofty (and largely unlikely) goal, but I want to work in the aerospace (emphasis on the SPACE) industry in some capacity, so I figure I’ll major in AeroE and specialize in spaceflight-related courses as much as possible.
I’m not naturally a tinkerer either, but I doubt every engineer builds their own cars and things like that.
Also, aerospace engineering is a part of mechanical, just a more specific part. That’s what I’ve heard anyway.
