  1. ISRU Technologies / Processes

  2. Atmospheric CO2 Compression • Process description: compression of Martian atmosphere (mostly CO2) • Scaling values (based on NASA Mars DRM 1.0): • 3 kg equipment / kg CO2 per day • System is assumed to include thermal control equipment • 15 We / kg CO2 per day • Volume requirement?

  3. Buffer Gas Extraction • Process description? • Scaling values (based on NASA Mars DRM 1.0): • 3 kg equipment / kg N2 per day • System is assumed to include thermal control equipment • 15 We / kg N2 per day • Volume requirement?

  4. Sabatier Process • Chemical reaction: • CO2 + 4 H2 CH4 + 2 H2O • Scaling values (based on NASA Mars DRM 1.0): • 22 kg equipment / kg H2O per day • System is assumed to include thermal control equipment • 50 We / kg H2O per day • Volume requirement?

  5. Reverse Water Gas Shift • Chemical reaction: • CO2 + H2 H2O + CO • Scaling values?

  6. CO2 Electrolysis • Chemical reaction: • CO2 O2 + CO • Scaling values (based on NASA Mars DRM 1.0): • 40 kg equipment / kg O2 per day • System is assumed to include thermal control equipment • 1190 We / kg O2 per day • Volume requirement?

  7. H2O Electrolysis • Chemical reaction: • 2 H2O  O2 + 2 H2 • Scaling values (based on NASA Mars DRM 1.0): • ? kg equipment / kg H2O per day • System is assumed to include thermal control equipment • ? We / kg H2O per day • Volume requirement?

  8. Ethylene Synthesis • Chemical reaction: • 2 CO + 4 H2 C2H4 + 2 H2O • RWGS as precursor reaction • Scaling values?

  9. Soil Water Extraction • Process description: • Transparent tent is used as greenhouse to heat surface soil to evaporate water in soil • Water is condensed at cold plate in tent and collected • Soil water content of 3% (by mass) assumed • Scaling values: • 1 kg equipment / kg H2O per day (based on Case for Mars, Ch 7) • System is assumed to include thermal control equipment • 500 We / kg H2O per day (this is an estimate) • Volume requirement?
