  1. AAE 450 - Senior Design Alec Spencer Pressurized Rover Preliminary Design Review 13 Feb 01

  2. Science • Long Range Exploration Strategy • Long Range Pressurized Rover • Capabilities • Redundancy • Greenhouse Concepts

  3. Long Range Exploration • Initially focus on scouting (6 months) • Scout geology • Chart water table • Focus on key sites (6 months) • Scientist discretion

  4. Rover Capabilities • Design Specifications • Range: 1000+ km • Crew: 2 (4 in emergency) • Duration: 10 days (30 in emergency)

  5. Rover Capabilities • Clearance: 0.85 m • Maximum speed: 40 kph • Maximum slope: 60o * • Maximum side-hill angle: 45o • Turning radius: 10 m

  6. Features • Control • Joystick • Modular Electronic design • Remote control capabilities • Science • Meteorology (autonomous) • Sonar or radar mapping (autonomous) • Drilling or core samples

  7. Features • External roll cage • 4 x 6 drive • 3 computer stations • Shower and chemical toilet

  8. System Redundancy • Propulsion • Main methanol engine • Methanol and O2 diesel cycle • CO2 buffer • Main source of heating • Electric • Emergency power to return to HAB • Acts as generator when not in use

  9. System Redundancy • Power systems • Generator powered by engine • Electric engine as generator • (Fuel Cell) • Batteries

  10. System Redundancy • Airlock • Emergency shelter in case of hull breach • Doubles as toilet and shower • Suit design

  11. Greenhouse • Weight • Lightweight if inflatable • Shielding • UV levels too high for plant life • Shielding for a large structure would be prohibitive
