Lunar gravity and geodesy mapping by KAGUYA mission and the origin of lunar dichotomy

In JAXA KAGUYA(SELENE) mission, using two subsatellites and VLBI observations by VERA 4 stations and international 4 stations, the first global accurate gravitational field of the Moon including the far-side was obtained. The first global accurate lunar topography was also obtained by a laser altimeter. Multi-frequency differential VLBI was proven to be the powerful technique for orbital determination(less than 1cm, 1mm in principle). Global distribution of lunar crust was obtained from gravity and topography data. The thinnest crust was beneath Mare Moscoviences on the far-side. 500-1000km scale far-side highland impact structures are supported mostly by the crust which would have been cooled faster than near-side crust.
