In June 2018, the Hayabusa 2 spacecraft arrived at the target asteroid Ryugu after three and half years journey. In addition, another spacecraft, OSIRIS-REx will soon arrive at its destination Bennu. With these arrivals, the solar system research is about to enter a new era. We have organized this small bodies session since 2012 and had a broad range of discussions from viewpoints of laboratory experiments, observations, space explorations, theoretical modeling, and sample analyses. In particular, this time, we aim to hold this session to bring the latest research on solar system small bodies, focusing on the initial results of Hayabusa 2 and OSIRIS-REx. Presentations in the related fields other than these two asteroidal missions are also welcomed.
