Given that seismic exploration is one of the most successful approach to study the internal structure of planetary bodies, it has been proposed to various planetary missions. Starting from Passive Seismic Experiment on Apollo missions, various seismic experiments were proposed over the next 50 years. Recently, several such proposals have been approved and thus we are entering a new active era of planetary seismology. In early 2019, the NASA InSight Lander successfully deployed the first seismometer on the surface of Mars and detected the first Marsquakes. In addition, recent global interest in lunar exploration has rekindled interest in a new seismic network on the Moon. In-situ resource utilization is being intensively discussed and seismic exploration has been investigated as an approach to search for subsurface water/ice. Finally, the Dragonfly mission was selected as NASA's next New Frontiers mission and a set of short period seismometers is being considered for its payload. With such a diversity of on-going and future missions, the next decade should see significant advances planetary seismology. The aim of this session will be to discuss the latest planetary seismology discoveries and possible future exploration and developments in this field. In terms of recent discoveries, the focus will be on analyses of InSight seismic data from Mars as well as results from other missions. The session will also include discussion on future missions, both selected and proposed. These include the active seismic experiment on the Japanese Lunar Resource Prospector mission and the seismic experiment on NASA's Dragonfly. Though planetary seismology has a long history dating back to the Apollo era, the associated research community is relatively immature due to the nearly 50-years gap in new data. We propose this session to provide opportunity to bring together scientist working on related topics and encourage discussion and collaboration for future development of this theme.
