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

S. Tachibana, +108 more
- 10 Feb 2022 - 
TL;DR: Tachibana et al. as discussed by the authors analyzed the morphological properties of small pebbles on the asteroid and concluded that they are representative samples of the asteroid's surface and subsurface.
Journal ArticleDOI

Samples returned from the asteroid Ryugu are similar to Ivuna-type carbonaceous meteorites

Tetsuya Yokoyama, +148 more
- 09 Jun 2022 - 
TL;DR: The authors measured the mineralogy and bulk chemical and isotopic compositions of Ryugu samples and concluded that the samples mainly consist of secondary materials that were formed by aqueous alteration in a parent body, from which Ryugu later formed.
Journal ArticleDOI

Formation and evolution of carbonaceous asteroid Ryugu: Direct evidence from returned samples

T. Nakamura, +217 more
- 22 Sep 2022 - 
TL;DR: In this article , the authors analyzed 17 samples of the carbonaceous asteroid Ryugu and found that carbon dioxide-bearing water inclusions are present within a pyrrhotite crystal, indicating that Ryugu's parent asteroid formed in the outer Solar System.
Journal ArticleDOI

On the origin and evolution of the asteroid Ryugu: A comprehensive geochemical perspective

TL;DR: In this paper , a comprehensive analysis of 16 representative particles returned from the C-type asteroid Ryugu by the Hayabusa2 mission is presented, which is consistent with multi-scale H-C-N isotopic compositions that are compatible with an origin for Ryugu organic matter within both the protosolar nebula and the interstellar medium.
Journal ArticleDOI

A pristine record of outer Solar System materials from asteroid Ryugu’s returned sample

Motoo Ito, +101 more
- 15 Aug 2022 - 
TL;DR: In this article , the results of a detailed bulk and micro-analytical study of pristine Ryugu particles, brought to Earth by the Hayabusa2 spacecraft, were presented, showing an intricate spatial relationship between aliphatic-rich organics and phyllosilicates.
