Seismic data obtained over a broad frequency range are very useful in investigation of the internal structures of the Earth and other planetary bodies. However, planetary seismic data acquired through the NASA Apollo and Viking programs were obtai...
Information on the lunar central core; size, current state and composition; are key parameters to understand the origin and evolution of the Moon. Recent studies have indicated that possible seismic energies of core-reflected phases can be identif...

We developed a seismometer system for a hard landing "penetrator" probe in the course of the former Japanese LUNAR-A project to deploy new seismic stations on the Moon. The penetrator seismometer system (PSS) consists of two short-period sensor co...
Further study for the planning of the post SELENE mission has been discussed by a dedicated working group. As the extension of the SELENE-B study [Okada, T., Sasaki, S., Sugihara, T., et al. Lander and rover exploration on the lunar surface: a stu...
