Crustal thickness of the Moon
Updated : 2011.03.28
Observation date :

 Based on the latest SELENE lunar gravity and topography model obtained by KAGUYA mission, the lunar crustal thickness map was revealed. The thickest crust is located in the southern rim of the Dirichlet-Jackson basin and the thinnest crust at the Moscovience basin. The thickest crust corresponds to the highest topography and is consistent with Airy isostasy. The thinnest crust is due to an abnormally large mantle plug.

 This new crustal model provides improved views of the farside basin structures over previous models, and suggests that the differences of type-I and type- II basins are probably due to difference of the ratio between the pre-impact crustal thickness (Moho depth) and impact scale.

 The above-mentioned result was published in Geophysical Research Letters.

 The data was processed by the RSAT/VRAD and LALT team.
