I was thinking about ways to make space stations more than just refueling stations. Imagine if you could dock with a space station made for science, transfer all of the physical data (Mainly surface samples) to a "lab" and have them run experiments on the things you have collected. It would take HUGE amounts of power to start and run these experiments though, so you would need the large solar panels along with the large batteries. The "Science Lab" could require 4 kerbals to do the experimenting, 8 of the largest solar panels to run the experiments, and maybe a 20,000 electrical charge (5 of the largest batteries) to start the lab. Reasons may be for later in development though. Like you discover technology, kind of like what has been done on the International Space Station in real life, to help civilian kerbals that will give you a credit/science boost in career mode. Fun optional part: Of course there has to be a down side or a risk. There would be a 20% chance to damage the experiment, so you would lose most of the science that came with it. A 10% chance to lose the experiment along with all of the science that would have been made from the sample. Finally we are talking about kerbals here a 5% chance to blow up random parts of the space station, and lose the kerbals in the lab.
