Hey guys, I've progressed quite a bit in the tech tree, but I just can't seem to get soil samples from the Mun back to Kerbin. Here's a screenshot from my techtree: I've tried several different designs, all of them rockets. SSTO's can't refuel anywhere yet so mine can't get to the Mun yet. Here's my ultimate goal: have a lander which can bring back several different samples from the Mun to Kerbin. If anyone could help me with pointers or a design that'd be great . Best, Stealth
