The Orange

The Orange is a skycrane system meant to land payload on the Moon and then return itself to lunar orbit to be refueled and reused for further payloads. It has a limited capacity, but is sufficient for supply modules or small crew facilities. Its core structure consists of a tall toroidal oxygen tank around a toroidal methane tank. Its engines and RCS thrusters are on extendable arms to mitigate damage to payloads when the engines ignite for landing. Payloads will have to supply their own landing legs.
