In-Situ Resource Utilization


Homestead Database

In-situ resource utilization (ISRU) is just a fancy way of saying that we want to use the resources that are available at the Homesteading site. This is critical to any space settlement because it costs way too much to send everything from Earth. Our Homesteaders are going to have to be as self-sufficient as possible if Lunar settlement is going to be a reality.

ISRU focuses mainly on mining. Collecting energy is covered on the Energy page. There’s no indigenous biological resources so that’s not a consideration (biological resources are covered on the Food page). And using the SPORE technique requires all Homesteads to engage in mining anyway.
