REVEALS research in ISRU: Transport of gases at Lunar conditions and concentrating solar utilization on the Moon

In-Situ Resource Utilization (ISRU) will be required for a sustainable, economical Lunar base. ISRU is an immense engineering challenge, characterized by low Technology Readiness Levels (TRL). First, in this presentation, an experimental study on gas transport at lunar conditions will be explained. Gas transport at lunar conditions is relevant to the sampling and extraction of volatiles, a key part of Lunar ISRU. Experimental results were coupled to physical models, and key properties were evaluated to assess the transport model fit. Key parameters necessary to define the gas transport rate are the porosity, tortuosity, pore diameter of the regolith medium, and the gas slip parameter. Second in this presentation, the ISRU research plans of Solar FTL and REVEALS will be previewed. A study to couple concentrating solar technology with ISRU processing technology is proposed. Concentrated solar technology has high potential for use in the lunar environment. Solar resource utilization will be a critical component to realized Lunar ISRU.

Garrett Schieber
Garrett is a PhD student in the Woodruff School of Mechanical Engineering and a Graduate Research Assistant in the Solar Fuels and Technologies Laboratory, and also a member of the REVEALS team. He received a BS in Mechanical Engineering from Iowa State University in 2015 and a MS in Mechanical Engineering from Georgia Tech in 2017. Garrett currently specializes in H2O transport within regolith and concentrating solar utilization on the moon. Garrett’s first experience with regolith was in undergrad as the President of the Iowa State Lunabotics Club, which participates in NASA Lunabotics mining Competition. Outside of work, Garrett enjoys cooking and baking, and watching Kansas City and Iowa State football.
