Well, just sent Bill to the Mun in a Ion hybrid lander, and 4 more crew in a Dragon replica will join him (Once I do Trans-Munar Injection) I used a Nautilus-X replica recently. It got into Mun orbit, but the Nuclear Motor overheated. The spacecraft was an Ore Carrier, and was part count heavy. The centrifuge was taking up space too. It had two drop-pods, one of which I had used to return a Kerbal I rescued. I got Barra Kerman (Engineer) and she hit the weak-spot (Some reaction wheels) and knocked off the whole Ore stack. She survived. The drop-pod didn't. However, the maneuver saved around 150 parts. Now the crew needs to be rescued. Just a small story. The base is doing fine.
