Greetings to everyone who happens to stumble upon this thread. I come to you with a problem today: I need to get to Duna in career mode (0.23) and I can't seem to design a ship good enough for it. I've been to Mun, Minmus and around Kerbol many times, and I can get there pretty easily. I want to go to Duna before I go to Eve because of Eve's very high gravity, and so I think that Duna will probably be easier. Let me just put my tech tree here so you guys can see what science I have unlocked. I'd say I have a decent number of things unlocked, and, from what I've seen, should be enough to get me to Duna. Unfortunately, I am not that great of a ship builder (I suck) and cannot get a good design. My lander isn't bad, but the rest of the ship... Anyways, there are a couple things that I would like to be able to have/do with this ship. This is a list of things I would like from most important to least important: 1) Must be able to get to Duna and back to Kerbin 2) If possible, I would like it to be manned with a crew of 1 or 2 kerbals 3) While I do have docking ports unlocked, I have not messed around with them yet, so I would probably mess something up if I try and dock two ships together in orbit 4) Reasonable room for errors, I'm an okay pilot, but I can't get to Mun and Minmus with only the Start science node. 5) As you can see, I don't have the amazingly efficient nuclear engines, but I can probably unlock them if necessary. 6) Any science tools I can bring along are very welcome. If you have a ship that meets at least a few of these requirements, I would be delighted to see them, if only to get some ideas. Thanks for reading -Chronin
