And there's a guy with 86.55 and doing mx/space.... weird eh?
Space is nice if you feel like doing some fun stuff, and the assignments aren't terribly stressful, at least for the space-specific subjects. Salah (the space head dude) pretty much does exam-less subjects, with emphasis on doing stuff by yourself. They're actually really good courses because you can diverge in a lot of different ways and still get good marks for them.
Doing stuff that is aeronautical specific instead of space is kinda boring - you do a lot more fluid dynamics, a lot more design, and a lot more structural analysis.
The other side of the coin is doing mechatronics or mechatronics/space. These focus more on control theory and programming, rather than structural analysis and fluids. Personally I think these subjects are more interesting, because you're not using just 5 formulae all semester for a certain subject. Adding space on top ot if gets you out of things like materials, and puts you into stuff like flight mechanics or building a satellite. Admittedly the satellite was a bit stressful the day it was due, but it was fun nonetheless.
Breakdown of space-eng subs (that I've been through):
first year: gay course with KC. Waste of time, but means to an end.
second year: this time it was mixed with flight mechanics - the flight mechanics bit sucked, but the space bit was kinda cool
third year: the fun shit..... we built two cubesats - 100mm x 100mm x 100mm satellites.
fourth year: doing shit with GPS & INS... pretty laid back course, nice change for 4th year...
