We discuss the charter and activities of the International Lunar Exploration Working Group (ILEWG), and give an
update from the related ILEWG task groups. We discuss the different rationale and technology roadmap for Moon
exploration, as debated in previous ILEWG conferences. The Technology rationale includes:
1) The advancement of instrumentation:
2) Technologies in robotic and human exploration
3) Moon-Mars Exploration can inspire solutions to global Earth sustained development.
We finally discuss a possible roadmap for development of technologies necessary for Moon and Mars exploration.
