I've always been fascinated with space and space travel and want to see humanity advance in that area. I've always thought the best way for me to contribute is to work in research and development for propulsion systems (which I'm interested in), however, my main passion in physics is astrophysics/cosmology. I'm trying to choose between: Doing a research BSc. (or PhB) in plasma physics. Doing a dual engineering/physics BSc. These two will obviously be much more applicable to propulsion systems. Or: Doing a research BSc. in astrophysics. Which won't be applicable to propulsion but is where my main interests in physics lie. I really would like to have a career in propulsion, but I'm not quite as interested in plasma/ion physics (though definitely not uninterested) as astrophysics. Does it really matter at this stage? Any advice would be greatly appreciated.
