Team A, Power Group Presentation Patrick Kennedy 1 / 16 / 01
Power Considerations HAB in transit to Mars HAB on surface of Mars Backup power HAB on surface of Mars Rovers on Mars Communication
HAB in Transit NASA plan: 30 kWe Sources considered Nuclear Fission Solar Arrays Fuel Cells Batteries Radioisotope Thermoelectric Generators (RTGs)
HAB in Transit (cont.) Primary selection: Solar Power Good power level Proven concept Backup selection: Regenerative Fuel Cells (RFC)
HAB on Surface NASA plan: 160 kWe Same sources considered as in transit Primary selection: Nuclear fission Great power level Good weight, size Backup selection: Solar Array/RFC Same system used in transit Less reliance on sunny day
Rovers 2 Rovers considered Sources considered Distance rover for multi-day trips Local rover for 1-day trips Sources considered Methane Engine Solar Arrays Fuel Cells Batteries Radioisotope Thermoelectric Generators (RTGs)
Rovers (cont.) Distance Rover NASA plan: 10 kWe Source: Methane Engine Good power Good weight, size Local Rover Lunar Rover: 1 kWe Source: RFCs Good size, weight Recharge from HAB power
Communication Antenna on main craft Source: Use power from HAB’s power source Antenna on separate craft Source: Solar Power Proven design
