About

Tatsuaki Okada is a leading figure in planetary science and space exploration, with a career defined by pioneering contributions to lunar and asteroid missions. His research focuses on the geophysical and geochemical characterization of small bodies, particularly through in-situ lander and rover operations. Okada’s major contributions include his foundational work on the SELENE-B mission, where he explored lander and rover strategies for lunar surface exploration (22 citations), and his leadership in defining the science objectives for the post-SELENE lunar mission (16 citations). He is also the driving force behind the MITSuME project, a multicolor imaging telescope system designed to detect and monitor explosive cosmic events (18 citations). More recently, Okada has been instrumental in the Hayabusa2 mission, where he contributed to mission planning and achievements (10 citations) and developed advanced noble gas mass spectrometry techniques for analyzing returned asteroid samples (4 citations). His work has directly enabled the analysis of extraterrestrial materials, bridging robotic exploration and laboratory science. Okada’s impact is evident in the enduring relevance of his research, which continues to shape the future of planetary exploration and sample return missions.
