In-Situ Resource Utilization for Lunar and Mars Exploration

Abstract

In-Situ Resource Utilization is the collection, processing, storing and use of materials encountered in the course of human or robotic space exploration that replace materials that would otherwise be brought from Earth to accomplish a mission critical need at reduced overall cost and risk. For the first time, a mainstream ISRU technology development program has been established by NASA to incorporate this approach into extended duration exploration of the moon and Mars. The program includes the development of capabilities to perform excavation and collection of lunar regolith, including imbedded volatile materials, and the production of oxygen to supply propulsion and life support consumables during the extended human missions currently planned to begin in the early 2020’s.
