I built a Rover and a lander to bring it to the Mun, but forgot to put RCS thrusters on any part of the craft, even when I had multiple mono-propellant tanks! It rotated like a tank, but I was able to get to the Mun. When I was tried to land, the craft had too much horizontal movement and it shattered into pieces! Luckily, the Rover remained intact, but with most of the Solar Panels broken (There were still enough for it to move around).
