Grabbed a class B using the probe at the bottom of the screen, got it in a 500k Kerbin orbit, tossed a habitation module onto it (top, with the docking port backwards... oops), then changed my mind and parked it at 200k over the Mun. Next I flew up 2400 liters of fuel (the cross-y module on the left) with one of the large RCS tanks and a bunch of solar panels, a mobile processing lab (doing this all in career mode), and a tanker with another 1200 liters of fuel and some badly needed lights. My Munar lander is docked with the central fuel tanks at the moment as well; I've been working through every Munar biome and bringing back surface samples, materials studies, and mystery goo canisters from each one, then dumping them all in the lab.
