Hello Alltogether. This is my Attempt in Playing Caveman (on Normal difficulty) to Fly Jeb To duna and bring him back Savely to Kerbin. To Achieve this a lot of work has flown into it, including mastering the Art of Docking without Monoprop, Building explicitely useful crafts (lift more than 2tons to Orbit 200km of Kerbit) and planning and assembling a Ship in Orbit that is capable to savely Fly jeb to and Back to Duna. It took me 5 Days for Planning and 2 Days for the mission itself.
