Presentation Transcript

  1. Lunar/Mars Exploration and Base Construction Power Systems

  2. Energy • Solar • Wind • Nuclear • In-situ propellant (methane) • Steam

  3. Solar • 5-30% efficiency • Mars receives 44% as much solar energy as Earth • Tracking/Non-tracking solar array • Dust?

  4. Solar

  5. Wind • Typical wind speed: .03-200 kph (67-125 mph) • Max speeds: 500-600 kph (300-375 mph) • Lower pressure reduces wind effects/100 mph wind on Mars=11 mph wind on Earth • Enough to turn wind turbines? • Constructing wind turbines • 30% efficiency

  6. Wind

  7. Nuclear • Size of a coffee can • 15+ year life expectancy • Dangers • Contamination of crew • Contamination of Mars/moon • Possible extra exposure to radiation

  8. Nuclear • Multi-mission Radioisotope Thermoelectric Generator

  9. In-situ Propellant (Methane) • In-situ propellant • Use Sabatier reaction to produce methane • Good for rover and CRV (Crew Return Vehicle) • Generators?

  10. In-situ Propellant (Methane) • Sabatier Reaction CO2 +4H2  CH4+2H2O • Water Electrolysis 2H2O 2H2+O2

  11. Steam • The possibility of drilling into the Martian core to utilize thermodynamic energy
