Wooo, update: I have a ride to Barcelona with three other guys from ISU on 2 September. And there is a small amount of funding available if I present our ISU team project paper at the International Astronautical Congress in Valencia. Getting to Spain was a huge hurdle, and staying in Spain—without running out of money—during September was a second hurdle that immediately followed that one. Other issues remain such as where I'm going to stay in Barcelona and Valencia, but hey—things tend to turn out well in the end if you put enough sensible effort into preparation.
