This critical operation, performed on February 22, 2019, constituted the most complex and risky part of the ISAS/JAXA Japanese mission: it required to bring the entire spacecraft in contact with the surface of Ryugu, entirely covered with boulders of all sizes. Its success demonstrates and translates an extraordinary and unique control of space operations by ISAS/JAXA engineers. A second sample collection could be performed in a few months, prior to the return to Earth: Hayabusa2 should leave Ryugu in December 2019, to land on Earth a year later. Our laboratories should thus get in 2021 samples collected at the very surface of one of the most ancient solar system objects, rich in particular of organics which might have played a major role in the evolution towards life on Earth.
