Pebbles and sand on asteroid (162173) Ryugu: In situ observation and particles returned to Earth

Science, 2022
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.
