To be fair, though, all of these are solved problems that are easily overcome with budget and outsourcing. Ex. you can buy quality carbon fiber tubes in whatever diameter and thickness you want from multiple suppliers, contract out the nozzle based on existing designs to a CNC milling or titanium SLS printing company, purchase aerospace-rated avionics packages, etc. The impressive part here is that the students seem to be doing a good chunk of these things mostly in-house and with less money than it would normally take.
Sure you can contract out the work, but paying for someone else to make a rocket you launch doesn't really qualify you to say that you did anything. It also doesn't teach you anything, so what's the point?
Most of what you work on in college is solved problems, because college is about learning and not about original research.
