In Situ Resource Utilization (ISRU) refers to the production of useful materials from the resources available at a given location. (The phrase is from the Latin in situ, meaning "at the site", or "in place".)
One form of ISRU is In-Situ Propellant Production, (ISPP), or manufacture of rocket fuel from local resources; the term ISPP is no longer currently much used, in favor of the more generic terminology ISRU, which incorporates use of in-situ resources for uses other than propellant.
ISRU can be categorized into production of materials useful at the current location, primarily:
- life support
- propellant
- radiation shielding
- construction and structural materials
- raw materials for other production useful for habitat expansion
materials produced for use elsewhere in space:
- propellant for exploration and colonization
- building materials for habitats and spacecraft
and materials produced as commodities for possible sale back to Earth:
- high-value materials, such as Platinum Group Metals
- bulk materials, such as nickel and iron refined from asteroidal resources
- materials for manufacture of solar power satellites to export energy to Earth
