Mechanical or Aerospace? Good minors? (My Plan)

Hi folks! I’m currently a community college student, and I have three great schools (also one military academy) for engineering here. Ever since I was young I was fascinated with space and wanted to do astronomy and also become an astronaut (I still kinda want to lol like that will ever happen). Since astronomy majors sadly don’t make a lot of money, I decided to do engineering. I already have experience with engineering, and I was able to do some aerospace stuff back in August with a sounding rocket project.

I really want to specialize in astronautical engineering, working on spacecraft. This first university has a great aerospace program, I plan to major in aerospace engineering specializing in astronautics and spacecraft design, but also minor in either astrophysics or planetary science (likely the latter since it doesn’t require any extra physics classes and is more relevant this day and age). Alternatively, I can do mechanical engineering instead. I do plan to go to grad school as well.

Another school I’ve been eyeing with a great reputation doesn’t offer an aerospace degree, but instead a mechanical or electrical engineering degree with a minor in “space sciences” which combines astronautical engineering and astronomy (their aerospace minor is aeronautics).

A third school in state is similar, but I am not sure if they have an astronomy minor, nor am I entirely sure if I want to go there. I plan to do more research.

I know mechanical might be altogether better for aerospace, but should I still do aerospace if I know thats what I want to do and also go to grad school? Is my choice in minor good for grad school?

Thank you!
