Cosmic dust measurement has been one of the fundamental investigations of the Solar System exploration and sample returns from low Earth orbit have substituted knowledge gaps of the terrestrial collection of astromaterials. Exo-planetary system studies now demand deeper understanding of the Solar System dust structure and compositions as templates for all other planetary systems in the Universe. Sample return technologies and operations have been extended to asteroids and comets, cosmic dust parent bodies, and advanced toward more challenging destinations such as Jupiter Trojans and icy satellite plumes. These achievements inevitably created the new research field of microgravity geology. After a quarter century of scientific and engineering advancements, Japan now has original dust detectors, collectors, and sample return instruments supported by ground hypervelocity impact and microgravity experimental facilities.
