When the R&D System came out, I made an unmanned probe to Duna that has a lander on its belly. The Lander got onto Duna safely, but I found one design flaw; no Drill. That's when I come here. I suggest that a drilling probe be added to the game in the next update, so that unmanned lander's can take in Soil samples and analyze them without Kerbal's doing it instead.
