Decided I would design a Mun rover (still quite early in my KSP career). Built the rover, slotted it into one of my rocket designs that I know can reach the Mun with one exception, using an unmanned command module. Got the rocket in LKO, slingshotted (correct terminology?) to the Mun, altered course so I was in the Mun's orbit and BAM. Out of electricity The only solar panels that were installed on the entire ship was on the rover, which had a nose cone covering it (yes I know it doesn't do anything except add mass but I like everything looking nice haha). Time to start again!
