  2. Subgroups • Analysis • Excavation and Delivery • Concepts • Public Relations

  3. Constraints The rover will land in a shadowed crater containing water ice. Max mass= 50kg Max power= 100W Mission will remain active on moon for one month. *Information obtained from: http://www.fsgc.engr.ucf.edu/isru/what.html Tasks Excavator arm must collect regolith up to one meter below surface. Must move regolith from arm to reaction chamber. Collect up to 100kg by end of mission. System must gather data on regolith such as shear, yield, compaction. Design Requirements

  5. SG5-UT Arm & Accessories • Sensors • Grip • Possible add-ons • CrustCrawler • 5-axis design • Programmable electronics

  6. A Basic Introduction to Molten Silicate Electrolysis • Advantages: • high concentration of silicates in the lunar regolith (~45%) • relatively high efficiency • ease of separation of oxygen from byproducts (just melt it, and then electrolyze it!) • Disadvantages: • high temperatures (power) required for reaction to take place

  7. General analysis procedure outline • Sifting • Conductivity separation chamber • Reaction chamber • Oxygen Separation • Oxygen Analyzer • Oxygen collection chamber

  8. Conductivity separation chamber The idea behind it: • O2 soil • ~700oC to increase conductivity • Due to heating, gases – mostly H2, H2O, CF4 (from solar wind, etc) that are in lunar soil are liberated

  9. Reaction chamber / Insulation The idea behind it: • Process • Insulation • Heat loss

  10. Oxygen separation chamber The idea behind it: • Along with O2, other gases escape our reaction chamber • It uses membranes that are selectively permeable to O2 Cerametic Inc. Ion Transport Membrane Cost: $10,000

  11. Gas analyzers The idea behind it: • Efficiency • Percent O2 • Possible loss of O2

  12. CONCEPTS • Modes • Transit • Calibration • Acquiring Regolith • Analysis • Standby • Timeline • Scenarios • The Glue

  13. Public Relations • Outreach • Published Articles • Presentations • Video • Website http://www.astro.fit.edu/isru/index.html
