  8. Budget breakdown: Approx 2,8 million Euros Hardware 30 % Launch 30 % Operation 30% Various 10 % 15th December 2008

  9. Euroluna • European Lunar Exploration Association, registered in Denmark. • Euroluna Ltd, registered in Switzerland • Volunteer based, shoe-string budget

  10. Team name: Euroluna • President: Palle Haastrup • Craft Name: ROMIT • Main web site: www.euroluna.org • Euroluna email: info@euroluna.dk • News at www.twitter.com/euroluna • Blog: on GLXP site

  11. Collaborators • Clyde Space Inc. • Langtved Data • Micro Aerospace Solutions, Inc  • University of Toronto • Preliminary contacts with: Jamesburg disc

  12. Key team members • Palle: Team leader • Tor: Software • Soeren: Mechanical design • Sten: Trajectory • Signe: Press • Erik: Software operator • Mogens: Embedded software • Jesper: Video processing chain • Tom: Revisor • Kertu: kontor • + many others

  13. Mission • Put a remote operated vehicle on the moon • Participate in the GLXP challenge

  14. Google Lunar X prize • 20 million $ 1st prize • 5 million $ 2nd prize • 5 x 1 million $ prize

  15. To win • Be the first team • Private funding • Get to the moon • Drive/move 500 m • Send back “video”

  16. GLXP mission requirements

  17. Euroluna technical solution • One integrated craft • Small rover • Bi prob rocket motor • Solar powered • Minimum design of space component.

  18. Key mission parameters • Departure from LEO (800 km) • Trajectory: Weak Stability Boundary • Design: no redundancy • Time planning: launch opportunity end 2009

  19. Romit Subsystems • PROPULSION • POWER • ATTITUDE CONTROL • ONBOARD CPU • WHEELS AND MOTORS • GPS • CAMERAS • COMMUNICATION • STRUCTURAL CONNECTIONS

  20. Thermal Analysis • Design temperature in space: -20 - +50 ° C • Design temperature on the moon: +30 - +50 ° C • This leads to an acceptable α/ε of between 0.65 and 0.88 • The outer coating: shade of grey and heat conducting

  21. Other specs • HAL specs (linux) • Connections: USB • Operation (out of rocket, attitude control, burn 3100 m/s, wait 4 month, turn around, break, land..) • Link budget: large disc needed.

  22. Mechanical and vibration analysis • Mechanical issues on connection between the two tanks. • Vibration analysis not made yet, but assumed to be no serious problem…

  23. Link budget

  24. Solar cell navigation (!) • By measuring the solar input to the 6 solar cells, we get a rough direction/orientation of the spacecraft. • Power measurement can handle this ?

  25. System Consumption/Production in Watt Motors 10 W for normal operation, 5 w/motor for exceptions Camera 3 W Motor for turning camera 1 W Computer 1.5 W Radio Transmitter 3 W Production with 3 layer solar cells, max 17 W Power consumption

  26. Trajectory design • Weak Stability boundary route • Advantages: all launches can be used • Disadvantage: time to moon, precision

  27. Mission plan outline

  28. Mission plan

  29. Moon operation mission plan

  30. Discussion • Main conceptual design frozen • Mechanical design still evolving • Offer for launch end of 2009 – but maybe Geo Transfer orbit in 2010 • We need to go commercial off the shelf, rather than custom designed.
