This the presentation for the internship project I conducted at CTAE in Barcelona, Spain as part of my master\'s curriculum at the International Space University

1. Preliminary Mission Analysis for the Barcelona Moon Team Rover 8/26/2010 1 Mike Safyan – ISU/CTAE

2. Project Goals Primary Goals Define an initial set of mission requirements Create a set of design spreadsheets Secondary Goals Provide some initial design recommendations 2 8/26/2010 Mike Safyan – ISU/CTAE

3. Google Lunar X-Prize International competition for private teams Safely land and operate a robot on the lunar surface Must be 90% privately funded (10% government) 21 teams participating (and 2 withdrawn) $30K registration, $30M prize purse 3 8/26/2010 Mike Safyan – ISU/CTAE

4. Barcelona Moon Team First Spain-based team Headed by Galactic Suite Moonrace Want to bring together Catalan (and Spanish) entrepreneurial, industrial and academic capabilities Want as much of the project as possible to come from local industry Want to be creative and fun 4 8/26/2010 Mike Safyan – ISU/CTAE

5. Previous Work Conducted Boris Maitre, UPC Master’s Thesis: Transfer trajectory – Hohmann Landing site – Luna 17/Lunokhod 1 Mass at launch: 0.5 to 8.5 tons (LEO) 0.3 to 3 tons (GTO) Launch Vehicle – Ariane 5 5 8/26/2010 Mike Safyan – ISU/CTAE

6. Cost Estimate 6 8/26/2010 Mike Safyan – ISU/CTAE

7. GLXP Rules for the Rover Travel a minimum of 500 meters from initial landing site. Transmit from the surface an “Arrival Mooncast” and a “Mission Complete Mooncast”. Contains a set of defined images, video, and data Approximately 500Mb 7 8/26/2010 Mike Safyan – ISU/CTAE

10. Lunar Terrain - General 10 8/26/2010 Mike Safyan – ISU/CTAE Lunar Mare relatively flat and smooth Lunar Highlands relatively rough, heavily cratered

11. Lunar Terrain – Rock Distribution 11 8/26/2010 Mike Safyan – ISU/CTAE Rock size and distribution is greater near “fresh” craters

12. Lunar Terrain – Lighting 12 8/26/2010 Mike Safyan – ISU/CTAE Assuming minimum 20° sun angle is needed for the Solar Arrays, that only gives 10 Earth days of lunar operation per lunar day

13. Summary of Rover Requirements Rover mass no greater than 80 kg. Traverse obstacles up to 20 cm in height. Maintain a ground contact pressure less than 7 to 10 kPa at all times. Traverse slopes, both up and down, of a minimum 20°. Minimum roving speed of 10 cm/s Complete the surface GLXP mission requirements within 10 Earth days. 13 8/26/2010 Mike Safyan – ISU/CTAE

16. Process 8/26/2010 Mike Safyan – ISU/CTAE 16 Analysis Trade-offs Recommendations Discussion Future Work

17. Rover Mobility 17 8/26/2010 Mike Safyan – ISU/CTAE

18. Power System Architecture 8/26/2010 Mike Safyan – ISU/CTAE 18

19. Rover Power 19 8/26/2010 Mike Safyan – ISU/CTAE

20. Communication System Architecture 8/26/2010 Mike Safyan – ISU/CTAE 20 High rate, UHF Ground Station Rover Lander Low rate, S-band Low rate, S-band High rate, X-band Low rate, S-band

21. Rover Communications 21 8/26/2010 Mike Safyan – ISU/CTAE

22. Rover Mass and Power Budgets 22 8/26/2010 Mike Safyan – ISU/CTAE

23. Rover Link Budget 8/26/2010 Mike Safyan – ISU/CTAE 23

24. Summary of Recommendations Design for low mass, cost and complexity rover design, landing site, path selection Choose mission unique aspects with minimal impact on rover design Use GLXP preferred partners where feasible Put any complex payloads on the lander Sell acquired data, such as mobility performance results 24 8/26/2010 Mike Safyan – ISU/CTAE

25. Moonbase Alpha/GLXP Proposal 8/26/2010 Mike Safyan – ISU/CTAE 25

26. Summary Initial set of mission requirements created Gained a better understanding of lunar conditions for mobile robotics Created spreadsheets for evaluating mission design options/feasibility Provided initial values for rover mass, power and link budgets 26 8/26/2010 Mike Safyan – ISU/CTAE
