A simple illustration of a possible future resources ecosystem is shown in Figure 2. As can be seen at bottom left, several types of vehicles are engaged in (multi-staged) geological exploration. The second phase, recovery, shows vehicles associated with open-pit mining on Earth (providing an incorrect but tangible image). Recovered ore is processed into useful products (e.g. water, oxygen, fuel) in a third stage at a refinery facility, which also has attendant infrastructure needs (here, power is shown). Next, the final product is transported - perhaps to a point of sale directly, e.g. a lunar base. Alternatively it may be launched, and go through another stage of in-space transport. It may be delivered to a facility (e.g a space station) or tug vehicle, before being used to refuel satellites.
