'''IN SITU RESOURCE UTILIZATION (ISRU)'''
   −
ISRU is focused on identifying sources of needed elements and materials from one’s immediate surroundings. For example, while the Martian surface is barren and desolate, its carbon dioxide atmosphere provides a source of carbon and oxygen while subsurface water ice provides a source of oxygen and hydrogen. Using electrocatalysis powered by solar panels, these two sources allow for the formation of breathable O2, methane for fueling rocket engines, and carbon monoxide for syngas. Meanwhile, Martian soil can be used as an aggregate base for concrete as well as a source for sulfur and basaltic minerals, whose significance is described in the featured projects below, Mars Bricks and Tractor.
