A research article in the 9 June 2022 issue of Science reports analytical results from the samples returned from the Hayabusa2 mission to the asteroid Ryugu. Kudos to Science for making the article available for free. The craft rendezvoused with the asteroid 27 June 2018 and returned 2 samples with a successful landing in Australia on 6 December 2020. The authors report that they were allotted ~125 mg and used 95 mg of sample for the work in the article.
The article, by over 140 coauthors, is a densely written chemical/mineral/isotopic abundance paper for specialists in cosmochemistry (which is definitely not me). The article concludes that the samples resemble C1 Chondrites absent “sulfates, ferrihydrite, and interlayer water”. According to the article, C1 Chondrites bear a close resemblance in elemental composition to the solar photosphere.
