Discussion of space resources often starts with the material that sounds most valuable. A more practical opening question is what a mission needs done.

NASA describes in-situ resource utilization as a connected set of activities, including acquisition, processing and use of local material. Its lunar technology work also includes excavation and site preparation. This suggests a useful way to think about an early resource economy: a sequence of services that make other activities possible, rather than a single dramatic extraction machine.
