Soluble organic molecules in samples of the carbonaceous asteroid (162173) Ryugu

Science, 2023
The Hayabusa2 spacecraft collected samples from the surface of the carbonaceous near-Earth asteroid (162173) Ryugu and brought them to Earth. The samples were expected to contain organic molecules, which record processes that occurred in the early Solar ...

Macromolecular organic matter in samples of the asteroid (162173) Ryugu

Science, 2023
Samples of the carbonaceous asteroid (162173) Ryugu were collected and brought to Earth by the Hayabusa2 spacecraft. We investigated the macromolecular organic matter in Ryugu samples and found that it contains aromatic and aliphatic carbon, ketone, and ...

Ryugu Asteroid

2022
(162173) Ryugu is a near-Earth C-type (i.e., carbonaceous) asteroid. It has been, after Itokawa, the second target for an asteroidal sample return, thanks to the JAXA Hayabusa2 mission (Watanabe et al. 2019). Most interestingly, Ryugu in situ observations in 2018–2019 have confirmed, as expected from its classification, the presence of significant ...

Hayabusa 2 returned samples reveal a weak to null magnetic field during aqueous alteration of Ryugu's parent body

Earth and Planetary Science Letters
The JAXA Hayabusa 2 mission returned 5.4 g of material from the C-type asteroid Ryugu. The Mn-Cr ages of dolomite in the returned samples indicate that Ryugu ’ s parent body experienced aqueous alteration sometimes between < 1.8 and 6.8 Myr after CAI ...
