OMG this is ridiculous! I have an expedition stranded in orbit around Ike, with no fuel, and only about 11t of rocketparts for building something to save the day. The problem is that the large kethane mining rig landed on a slope and fell on it's side, rendering it useless, so now the only way to get kethane for refining fuel and printing rocketparts is to build a kethane miner that weighs less than 11t. So I build a small rover and a small miner in Ike orbit, and sent the rover down to search for a flat area in the kethane field. Then, with lots of mechjeb assistance, I landed the miner right next to it and, thinking that nothing more could possibly go wrong, I deployed the drill. It was too low. Epic disappointment. So now, as I type, I have a tiny kethane miner hovering in low gravity on a small engine half a meter above the terrain, held stationary by the translatron, mining kethane and converting it to fuel on the fly.
