2. Power Considerations HAB in transit to Mars HAB on surface of Mars
Backup power
HAB on surface of Mars
Rovers on Mars
Communication

3. HAB in Transit NASA plan: 30 kWe Sources considered Nuclear Fission
Solar Arrays
Fuel Cells
Batteries
Radioisotope Thermoelectric Generators (RTGs)

4. HAB in Transit (cont.) Primary selection: Solar Power
Good power level
Proven concept
Backup selection: Regenerative Fuel Cells (RFC)

5. 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

6. 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)

7. 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

8. Communication Antenna on main craft
Source: Use power from HAB’s power source
Antenna on separate craft
Source: Solar Power
Proven design
