Here's a thought.. any craft with science modules or kerbals (status reports) on it will give an amount of science points that will be removed again if the craft is removed/destroyed/reclaimed. The amount of science points depends on its location. Removing these points can let your total go down below 0, and having multiple stations in the same place gives reduced results just like normal science does. It requires at least one antenna for transmission, any number of science-capable parts, and any one part that has produced power in the orbit you leave the craft at, when you go back to the space center. It also requires a drone or manned capsule of some sort. Of course, stations could also give additional permanent science points up to a certain maximum per location, for being there for a long time. I'd love to see some telescopes, by the way. And more science tools of any kind. Give us a bunch of random crap to haul over to the whole galaxy, and give less points for each item. Maybe make some of them really big, so you just take them up into space to scrape together those last few points.
