I am trying to design the rover but it's hard to add mining drills and a detection module while keeping the whole thing compact AND look realistic. So, for recap, you want some kind of spacecraft with: a Propulsion system, a Module capable of staying in a stable Duna orbit and detect Kethane on the surface, a Lander with refining Kethane ability, a Rover with mining drills, empty tanks for Kethane and a detection module I usually do not put mining stuff on my rovers, but only on landers. So, I started to recycle an old idea I had for a drop pod. I could add a Kethane detector on it, if you like the idea to have your rovers detect Kethane and do science, before sending the big drills and their crews via landers. Tell me what you think.
