I was just coming here to talk about this. I hate garbage. I know there is a pretty small chance that I will smash into a discarded fuel tank, but it really bothers me seeing it swing around the planet in its ugly misshapen orbit. So far I have only manage to put satellites in orbit cleanly, with out anything left over, but a Mun landing with the current parts is just not possible. As far as I can tell. What I have been trying to do lately. 1. No junk floating in space or left on the surface of the Mun. 2. Land safely on the Mun, place a probe on the surface. 3. Place a satellite in orbit around the Mun. 4. Return crew home. Not needing to be done in any order, but all needing to be done in a single flight. So far I can get three out of four of these most of the time, but until we get docking I do not see how I could manage all four with the current parts. My computer isn\'t great, and starts to stall out after adding my 12th-14th booster so I have not been able to build any titans to carry up a LEM type craft with more than than a single engine. Once we can leave a rocket in lunar orbit to fly back to Apollo style re-dock and have it carry us home we will be set. I keep thinking about flying a whole space station to Mars. or... what would you kall a kerbal Mars? Kars? Are we all going to fly to Kars?
