I seem to be stuck in a catch-22, in that I need to obtain more science to unlock more ways of obtaining science. I've almost completely used up the available science for Crew reports, goo, and materials lab, at least through low-orbit. I've seen a lot of people claiming to be able to get tons of science through landers, rovers, mun soil samples, etc, but I don't have the parts (or the science points) required. Any tips? (the more details, the better)
