Functional Chemistry of the Hayabusa2 “Interstellar Twinkie” Revealed by Cold-Stage, Monochromated Electron Energy Loss Spectroscopy
[#6461]
The abundant aromatic and ketone carbon functional group ingredients of an "interstellar twinkie" from the Hayabusa2 collection are revealed by cold stage, monochromated electron energy loss spectroscopy.

NIR Features Reflecting the Space Weathering Effects on Asteroid Ryugu
[#6247]
This study examined how space weathering affects the spectral characteristics of asteroid 162173 Ryugu through sample analysis. The findings reveal clear trends in the 2.0 µm slope and the 2.7 µm band. And, a mechanism for these changes is suggested.

Interaction Between Clay Minerals and Organics in Asteroid Ryugu
[#6404]
We show evidence of organics trapped within the interlayer space of smectite in Ryugu. No such organics are found in the Orgueil CI meteorite, probably due to its oxidation on Earth. These might be responsible for the NH signature in Ryugu particles.

The Elemental Composition and Variability of Ryugu Samples, CI Chondrites, and Kainsaz Assessed by ICP-MS
[#6069]
In order to assess their elemental compositions and representative sample masses, ICP-MS data was obtained for ~3 mg Ryugu and Kainsaz and for ~50 mg powder samples from the CI chondrites Ivuna (2 x), Orgueil (3 x) and Y-980115.

Shock Metamorphic Effects in the Ryugu Carbonates
[#6384]
Our TEM observations demonstrate a variability in shock metamorphic effects among carbonates in the Ryugu samples, indicating that not all carbonates were affected by the mild shock metamorphism.
