I'm planning on getting a PhD in Aerospace Engineering and was wondering what kind of companies do research for space exploration/colonization. I need to know this so I know which university to go to so my career will be literally outside waiting for me. I heard the location with the most aerospace companies is in California. I was planning on going to University of Illinois at Urbana-Champagne. I want to make a career out of researching new ways to go into space more efficiently and effectively.
