Go to a school with a student satellite team (Score 1)

I'm a PhD student in Aerspace at Cornell, where I also did my undergrad (and somewhere you should definitely check out, especially if you're in the area). At Cornell, we've very successfully competed in the university nanosat competitions (NANOSAT-4 with CUSat and NANOSAT-6 with Violet). Nearly everyone from these teams goes on to work in the space industry. In fact, SpaceX, Boeing, and others come to campus specifically to recruit from within CUSat and Violet.
