We performed cratering experiments on targets composed of glass beads with a power-law size distribution that simulated the surface of rubble-pile asteroids, and we improved the previously studied reduction factor on the crater size scaling relati...
Radiation phenomena are usually observed during fracture of quartz-bearing rocks. Since quartz is a piezoelectric material, the associated electrical processes such as the electrification of fracture surface and the flight of electrons between fra...

The Hayabusa2 spacecraft investigated the C-type (carbonaceous) asteroid (162173) Ryugu. The mission performed two landing operations to collect samples of surface and subsurface material, the latter exposed by an artificial impact. We present ima...
We have developed a method to investigate the whole mass-velocity distribution of impact fragments generated by catastrophic disruption of simulated planetesimals. Flash X-ray radiography including 12 iron particles for tracers was used to visuali...
