In Situ Resource Utilization 2008 Field Campaign
What is Lunar In-Situ Resource Utilization (ISRU)? ISRU involves any hardware or operation that harnesses and utilizes ‘in-situ’ resources to create products and services for robotic and human exploration In-Situ Lunar Resources § ‘Natural’ Lunar Resources § Discarded Materials Lunar ISRU Products and Services § Excavation, Site Preparation, and Outpost Deployment/Emplacement § Mission Consumable Production § Outpost Growth and Self-Sufficiency Benefits of ISRU § Increased science and exploration hardware (instead of consumables) § Increased safety, crew exploration time, and self-sufficiency § Technology spin-in/spin-offs help recycling on Earth & space economy

ISRU Development Strategy Develop ISRU Technology and Systems in 4 Phases (2 -4 years each phase) • Phase I: Demonstrate Feasibility • Phase II: Technology and systems evolution optimized vs key performance parameters • Phase III: Modify and test for lunar environment applicability • Reach TRL 6 by Lunar Surface System (LSS) PDR (2014) Coordinate development of ISRU Technologies & Systems with Other LSS Elements • Identify common requirements, processes, hardware, and operations • Coordinate development of hardware to align project schedule Utilize Laboratory and Analog Site Demonstrations to: • Demonstrate capabilities and operations • Demonstrate evolution and incremental growth in technologies and systems • Perform joint hardware and operation tests with other Surface Element Projects • Develop partnerships and relationships across NASA and other US government agencies, and with International Partners, Industry, and Academia Be Prepared to Participate in Robotic Precursor Missions • Site characterization and resource mapping • Subscale ISRU demonstrations for subsequent mission risk reduction • Outpost ‘dress rehearsal’ mission including other LSS elements
2008 Field Test Background • Hardware developed by the ISRU project needed to move from the laboratory to more challenging conditions • Tests in a lunar analog were desired • Partnered with PISCES via a NASA Innovative Partnerships Proposal to develop a test site to meet our needs – Appropriate soil, limited vegetation, site accessibility, infrastructure to support the test team
ISRU Analog and Field Test Site Requirements • Minimum vegetation (including ability to remove vegetation) • ‘Good’ Weather – Minimum rain and wind – Lots of sunlight – Reasonable temperatures (unless specifically needed for test objectives) • Open and relatively flat areas for ‘Outpost-like’ operations • Varied terrain and rock features for resource prospecting and science operations • Local material with similar physical characteristics to the Moon for excavation and site preparation • Local material with similar mineral characteristics to the Moon for resource prospecting, oxygen extraction, and processing • Local material that can be modified, processed, and permanently altered for site preparation and construction
Analog and Field Test Site Infrastructure Needs • Access – Easy access by all participants and hardware by government, industry, academia, and international space agencies – Access and operations day and night if required – Access to site for ~14 days per test program – Security to control access of non-participants and secure hardware • Personnel Support – Lodging and food near test site for test personnel to minimize travel time and logistics to/from test site – Personal hygiene facilities and refreshment/food capability at test sites or within reasonable distance so testing is not impacted – On-site medical support for first aid & emergencies with rapid access to near-by hospital if required (< 1 hour) – Meeting areas for planning and post-test debrief – Parking • Test Operation Support – Shelters & tents for personnel, in-site assembly/maintenance, and weather protection – On-site power (10’s of KW) and battery recharging capability – Gases and cryogenic fluids for test activities (oxygen, nitrogen, argon, helium, methane, etc. )
Analog and Field Test Site Infrastructure Needs • Test Setup Support – Reasonably close to airport for shipment of hardware – Ability to ship and store hardware to site before personnel travel to analog site – Access to workshop for test article storage, assembly, and maintenance (tools and floor space) – Support equipment to move test hardware from assembly area to test site and back; possibly on daily basis if hardware can not be left out overnight or fails to operate properly. – Wireless communication capability and satellite communication capability to run hardware remotely, interact with remote operation centers, and daily e-mail communication – Environmental and cultural compliance and approval
PISCES Field Test Preparations • Worked With NASA Perform Site Selection – Process Completed in Jan/Feb • NASA worked iteratively with PISCES to develop a Site Requirements Document – Finalized in July • Site Layout Visit and Logistics Inspection Conducted in August • Weekly Telecons Held To Work Out Details – Equipment Transportation, Consumables, Emergency Medical Plan, Accommodations, Communications, Food, Water, Shelter…. – Last Telecon held one week before execution

Why Perform Analog Field Tests? Concrete Benefits of Field/Analog Testing • Mature Technology – Forces design decisions to be made and gets hardware out of the laboratory – Develops technologies and systems at relevant scale and initiates the systems engineering & integration of multiple elements • Evaluate Lunar Architecture Concepts Under Applicable Conditions – Demonstrate feasibility for ISRU to provide Outpost with oxygen at relevant processing rates/scales – Demonstrates use of modular units for interconnection and growth – Demonstrates feasibility of multiple science instruments on mobile platform for RLEP 2 -type mission • Evaluate Operations & Procedures – Evaluate operations, controls, and interactions required for end-to-end oxygen extraction – Evaluate operations, controls, and interactions required for mobile science and ISRU precursor – Evaluate remote operations and communications impacts on hardware and performance – Evaluate science vs. engineering aspect to instrument data and operations • Integrate and Test Hardware from Multiple Organizations
Why Perform Analog Field Tests? Indirect Benefits of Field/Analog Testing • Develop Teamwork and Trust Early – Multiple Centers and Organizations Learn To Work Together • Develop New Partnerships – Informal discussions of each other’s work leads to ideas for future partnerships • Develop Data Exchange & Interactions with International Partners (ITAR) – An important barrier that is frequently ignored until field tests force the issue • Outreach and Public Education – Inspiring the next generation – Building ground roots support with the public
Outreach Activities • Visited local schools to talk about exploration, over 700 children attended • Planning a demonstration day at the Imiloa Center in Hilo on Saturday, 11/15

ROxygen Setup
Test Results (more to come) • PILOT – Significant water generated from regolith on every process run – First two runs conducted without water clean up, so a significantly acidic water was generated – Run three used water vapor scrubber and water was visibly cleaner – If analysis proves that water scrubber is working, water electrolysis operations will begin Tuesday. THAT MEANS OXYGEN WILL HAVE BEEN PRODUCED FROM HAWAII VOLCANIC SOIL WHICH IS SIMILAR TO THE MOON!!! • RESOLVE has Drilled 4 core samples – Regolith Volatiles Characterization experiment noted CO 2, H 2, O 2 and water during heating – Regolith Oxygen Extraction generated water, as expected, during one hour reduction process • ROxygen Operations begin today (Hurricane Delays)
