I'm fairly new to this game and still learning some basic stuff like how to orbit. It's tough to understand all the little details. Anyway, I want to plan something somewhat ambitious for my first "big" project in-game. Obviously it's something that will require me to understand the finer details of orbiting and docking, so I won't be able to put it into practice for quite some time, but I want to put a station in orbit around Kerbin. What I'd like to do is basically make it a fueling outpost for inter-planetary trips. My idea was to put a station with several Jumbo-64s in orbit so I could launch lighter vehicles, have them dock with the fuel tanks, undock the tanks from the station and then use that to fuel the journey. It'd also require replacement tanks. Feel free to tell me that my idea is incredibly stupid and pointless and overly ambitious. I'm open to any and all criticism you may have considering I'm still at the point where I have trouble launching a rocket that doesn't fall apart in flight. Anyway, I'd like to build a station and I do want it to be more than just some orbiting fuel tanks. To build said station I'd like to have a heavy lift vehicle, especially since said HLV would come in handy at other times. All of my attempts so far have been unsuccessful. Does anyone have any suggestions for how to go about building one?
