  1. Project Xpedition Spacecraft Senior Design – Spring 2009 http://eng.purdue.edu/jump/25cc30

  2. Motivation: Commercial Lunar Missions Small Payload Resupply Lunar Base

  3. Project Xpedition Requirements • Land on the Moon • Move 500 meters • Transmit HD pictures and video to Earth • Survive the Lunar Night • Minimize cost with 90% reliability Project Xpedition

  4. Payloads • 100 g • 10 kg • 1700 kg

  5. Mission Phases • Earth Launch • Lunar Transfer • Lunar Descent • Locomotion 500 m

  6. Earth Launch 180 ft 160 ft 110 ft Falcon - 9 Dnepr-1

  7. Earth Launch • Site: BaikonurCosmodrome, Kazakhstan • Cost: $5M 250 Mile Parking Orbit

  8. Orbital Transfer Vehicle Lunar Lander

  9. Attitude Control Solar Arrays unfold 8’ Hall Thruster produces 80 mN of thrust Internal View 880 lbs in Low Earth Orbit

  10. Lunar Transfer Attitude Star Sensor Sun Sensor Communication Reaction Wheels Chemical Thrusters S-Band Antenna Power 2 Solar Arrays Lithium-Ion Battery

  11. Lander is self sufficient • 160 kg Lander mass • Half of mass is propellant • 25 km parking orbit • 2 hour orbital period

  12. Solar Panel Communication Antenna and Motor Camera H2O2 Tank Space Balls Housing Attitude Control Thrusters Radial Flow Hybrid Engine 3 ft. Helium Tank CPU Radiator Attitude Sensors

  13. Apollo 12 Surveyor 3 40km Landing Site: Mare Cognitum

  14. Mission Requirements Land on Moon Move Payload 500 m Take Picture

  15. New lander picture, Size, (scaled) location, same for locomotion, text boxes/ what text do I use, balls behind leg?,

  16. New lander picture, Size, (scaled) location, same for locomotion, text boxes/ what text do I use, balls behind leg?, Dust Removal Vibration Motor Camera Battery Main Axel and Motor Housing CPU Communications Transceiver Lexan Shell 100g Payload Performing system analysis

  17. Minimum Turning Radius: 2.5 in Mission Requirements Land on Moon Move 500m Take Picture Taking Photo of Lander Removing Dust All Systems Are GO! Avoiding Obstacle Cruise Speed: 3.2 mph

  18. 10 kg Payload 10 kg Lunar Lander Mission Requirements 230 lbs Lander 270 lbs Propellant 500 lbs Total Land on Moon Move 500m Take Picture Survive Night Hop Engine Thrust: 45 lbs Burn Time: 135 sec

  19. Mission Requirements Land on Moon Move 500m Take Picture Survive Night Record Video 500m

  20. Completed lunar descent • Full stop • Begin locomotion Large Payload 300 ft Attitude Thrusters • 16 ft Main Engine Avg. Thrust: 230 lbs Burn time: 60 s • 6 ft

  21. Mission Requirements: Move 500 meters Land on moon Resupply base

  22. Cost Per Kilogram Mission Cost $271Million $223 Million 92% Success $30 Million 72% Success $27 Million 72% Success $3 Million $130k $27M Cost - $22M Purse = $5M Net Mission Cost

  23. Results Recommendations: Balance reliability and cost Electric Propulsion for Lunar transfer Soft land on Lunar surface Google Lunar X PRIZE: $27M mission accomplished for $5M Many viable locomotion methods Potential to open commercial market
