ISRU O2 Production and Construction
Major Results of Test Campaign
Dust to Thrust Successful: Demonstrate hardware and operations in all steps in ISRU from finding resources to utilizing in power and propulsion applications

Integration of Surface/Transportation Elements Successful: Integrate ISRU, Power, Fluid Management, and Propulsion modules to 'Close the Loop' for better understanding of interfaces and design impacts

  • Extracted oxygen from local tephra (28 gms or 9.6% ave. yield) using advanced processing and regolith transfer hardware in end-to-end configuration
  • Electrolyzed water from tephra and fuel cell, transferred oxygen to cryogenic cart for liquefaction, and performed 17 LO2/CH4 thruster firings; "Dust to Thrust"
  • Sintered two surface pads with two different methods and performed thruster firings with high speed camera to understand plume effects on unmodified and modified surfaces
  • Integrated NASA and CSA/Canadian hardware in multiple critical applications
  • Operated RESOLVE remotely from KSC and Solar Collector, Carbothermal Reactor, and Water Electrolysis systems remotely from JSC
  • Tested SMD FSAT and MMAMA instruments for site/mineral characterization and support oxygen extraction process evaluation
  • Completed field geology training with NASA and CSA managers and a CSA astronaut
