ILEWG Report and Introduction to EPSC session on Lunar Science and Exploration B. Foing ESA/ESTEC & ILEWG, postbus 299, 2200 AG Noordwijk, NL (Bernard.Foing@esa.int) Abstract We shall introduce the TP4 session on Lunar Science and Exploration and present a status report of ILEWG/COSPAR International Lunar Exploration Working Group to EPSC 2015. 1. Lunar session description This TP4 session will highlight latest lunar science and exploration results, and recent missions. It will address key questions on lunar geochemistry, geophysics, evolution, environment, volatiles relevant for planetary research. We plan overview talks, contributed oral or poster presentations and workshop discussions. In the last decade, an international fleet of orbiters (SMANRT-1, Kaguya, Chang'E1 & 2, Chandrayaan- 1, LRO/LCROSS, Artemis, LADEE, GRAIL ) has unveiled new faces of the Moon with new discoveries and questions. The Chang’e 3 lander and rover have opened a new lunar decade of surface activities towards a lunar robotic village with strong opportunities for science and exploration, and preparation for humans. We shall discuss EPSC community inputs developing ILEWG/COSPAR, ISECG and other global roadmaps for robotic/human exploration. How can the community support and prepare for upcoming lunar landers or orbital missions? The workshop will include the discussion of strategic measurements needed for exploration, and of possible science, instruments, terrestrial field work and simulation preparations. 2. ILEWG report The International Lunar Exploration Working Group (ILEWG) was established in April 1995 at a meeting in Hamburg, Germany. As established in its charter, this working group reports to COSPAR and is charged with developing an international strategy for the exploration of the Moon. It discusses coordination between missions, and a road map for future international lunar exploration and utilisation. It fosters information exchange or potential and real future lunar robotic and human missions, as well as for new scientific and exploration information about the Moon. We refer to COSPAR and ILEWG ICEUM and lunar conferences and declarations [1-19], present the GLUC/ICEUM11 declaration and give a report on ongoing relevant ILEWG community activities. We discuss how lunar missions SMART-1, Kaguya, Chang'E1&2, Chandrayaan-1, LCROSS, LRO, GRAIL, LADEE, Chang'E3 and upcoming missions contribute to lunar exploration objectives & roadmap.
