Good afternoon, everyone

I have a master's degree of an M.S. in Aeronautics specializing in Space Operations and trying my best to go for the Aerospace/ Defense Industry (Space) but hitting into a difficult time in my life in that I may not have enough skills I need to get into the companies like Boeing, Lockheed Martin, Northrop Grumman and the like. I do want to end up with NASA's Artemis program, but I can do other space programs and the defense I am open to that. (I don't want to go for the airlines nor commercial, they don't interest me).

I want to return back to the University because I am lacking some engineering skills I need, and some of the positions I want to go for say engineering. Also, I got hit by the engineering bug later in my life and I am almost in my 40s and its scaring me, and the fact universities are expensive considering I am a recent graduate of Embry-Riddle and ERAU is not an affordable university. So is there a university I can go to for engineering that is not going to break the bank or regardless of it will break the bank but one that will lead me to it.

I also heard of internships, and I seemed to miss the boat at the time when I enrolled but it was during COVID, and things were lockdown. Any advice is helpful.
