So here is the story, I have the kethane mod installed so I sent up 2 rockets a satelite kethane scanner that runs on an ion engine, and a miner. The miner I landed successfully but the pilot is still stuck up there and I want to get him back. But since trying this Challenge every lunar lander I have made to try to rescue him has failed miserably. The miner could return to earth it has a chute and enough fuel, but I want it to stay there. The rockets I tend to make end up heavy and take 3 hours to turn from retro to pro-grade. And on landing I just end up running out of fuel and crashing to my dismay. Any tips or designs that you have found helped you with this task? The lander. The Miner. Satellite.
