Project Xpedition Spacecraft Senior Design – Spring 2009 http://eng.purdue.edu/jump/25cc30
Motivation: Commercial Lunar Missions Small Payload Resupply Lunar Base
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
Payloads • 100 g • 10 kg • 1700 kg
Mission Phases • Earth Launch • Lunar Transfer • Lunar Descent • Locomotion 500 m
Earth Launch 180 ft 160 ft 110 ft Falcon - 9 Dnepr-1
Earth Launch • Site: BaikonurCosmodrome, Kazakhstan • Cost: $5M 250 Mile Parking Orbit
Orbital Transfer Vehicle Lunar Lander
Attitude Control Solar Arrays unfold 8’ Hall Thruster produces 80 mN of thrust Internal View 880 lbs in Low Earth Orbit
Lunar Transfer Attitude Star Sensor Sun Sensor Communication Reaction Wheels Chemical Thrusters S-Band Antenna Power 2 Solar Arrays Lithium-Ion Battery
Lander is self sufficient • 160 kg Lander mass • Half of mass is propellant • 25 km parking orbit • 2 hour orbital period
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
Apollo 12 Surveyor 3 40km Landing Site: Mare Cognitum

Mission Requirements Land on Moon Move 500m Take Picture Survive Night Record Video 500m
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
Mission Requirements: Move 500 meters Land on moon Resupply base
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
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
