Asteroids are the remnants of the process by which planets formed from the protoplanetary disk. Laboratory analyses of materials originating from asteroids give us the unique opportunity to reveal the formation history of our Solar System about 4.6 billion years ago. To obtain surface regolith in the low-gravity and vacuum environment, a gas-driven...
