Two papers on samples from the asteroid Ryugu brought back to Earth by the asteroid probe Hayabusa2(※1) have been published in the major British online journal Nature Astronomy(※2) on December 21, 2021 (Japan time).
These papers are based on the initial description of the returned by Hayabusa2 samples of Ryugu conducted at the curation facility(※4) of the JAXA(※3). The returned by Hayabusa2 samples show the overall characteristics of the asteroid as known from field observations, and it is clear that Ryugu is a primitive asteroid rich in water and organic matter.
