Friend of mine gave me the idea from a ski trip they had to the Alps. Little cabins that are there for people to use in an emergency. Well it gave me the idea for the moon. What happens when you crash, or have a major meltdown and your further from base than your air supply will take you. These things would have oxygen supplies, food, water, power, emergency radios, a homing beacon and pretty much everything you need to survive for a week while help comes. These have extra shielding to protect you from radiation exposure. These things will never fly again, so why not make something useful out of them. 1/1000 scale.
