LGIO moon rocket

Despite its single-stage design, this rocket can in fact land on Luna, if you use the fuel efficiently. The 4 G-1 engines are very powerful and can yeild TWRs above 20 even over Droo when the fuel starts running low, so very low throttle is required to not just rocket away from the moon at high velocities. Also, I didn't include the interior, because doing so would set the CoM off balance and the SAS would refuse to provide pitch stability. The cargo bay just below the window can open to allow Grace to go out for a moonwalk.

Bear terminators not included (hopefully).
