Science Summary of Kaguya Mission

Abstract

The Kaguya mission completed by collision of the Kaguya spacecraft on targeted place of the Moon on June 12, 2009. The Kaguya science team makes endeavors to archive data for data opening to public, and to study using the Kaguya data. Although data analysis and science study are ongoing, scientific achievements obtained so far are summarized concerning with the origin and evolution of the Moon as a ultimate science target of Kaguya mission: Ubiquitous identification of pure anorthosite in outcrops of central peaks of large craters by MI and SP, discovery of multi reflectors of radio waves under large mares and ocean in the nearside by LRS, confirmation of free-air gravity anomaly in the whole Moon and identification of farside anomaly different from nearside one of mass concentration by RSAT, confirmation of lunar global topography by LALT, re-estimation of crustal thickness by Kaguya data of gravity and topography, re-estimation of formation ages of farside mares by crater counting using high resolution images of TC, confirmation of magnetic anomalies and mini-magnetosphere by LMAG and PACE, reconfirmation of global distribution of radioactive elements K, U and Th by GRS, and discovery of solar wind proton reflection and access into lunar wake by PACE.
