| Research Abstract |
We analyzed Apollo retrieved samples to study their 3D grain properties and spectrographic properties. Together with the remote sensing data obtained in the Kaguya project, the results were used to compute lunar global maps on maturity and magnesium contents. We also studied the effect of lunar surface condition on the spectrographic properties. Moreover we performed the grain-scale numerical simulations using the obtained grain properties, which helps to evaluate the mechanical properties of lunar soil (bulk density, compressibility and shear strength) from its maturity index. Based on these results, we proposed some future missions on lunar exploration by JAXA
