Stratified Evolution of Ryugu’s Regolith Revealed by Spectroscopic Analyses of Two Hayabusa2 Collected Particles

The Astrophysical Journal
We present Fourier transform infrared (FTIR) and Raman spectroscopic analyses of two particles (A0226 and C0242) returned from the C-type asteroid Ryugu by the Hayabusa2 mission.

Chemistry in Retrieved Ryugu Asteroid Samples Revealed by Non-Invasive X-ray Microanalyses: Pink-Beam Fluorescence CT and Tender-Energy Absorption Spectroscopy

Geosciences
The Hayabusa2 space mission recently retrieved 5.4 g of material from asteroid Ryugu, providing the first direct access to pristine material from a carbonaceous asteroid. This study employs a novel combination of non-invasive synchrotron X-ray techniques

Sodium-rich Particle as Evidence of Recent and Intense Micrometeoroid Bombardment on Asteroid Ryugu

The Astrophysical Journal Letters
The Hayabusa2 spacecraft returned regolith particles of the near-Earth asteroid Ryugu. We investigated two of these particles and found differences in space weathering by-products, including chemical abundance, redox state, and surface morphology.

H+ irradiation of ordinary chondrites supporting observations of Torifune by Hayabusa2#

Astronomy & Astrophysics
Context. The Hayabusa2# mission has performed a flyby of the S-type asteroid Torifune, and thanks to the NIRS3 instrument, it has collected infrared spectra in the 3 μm region for the first time on such a small dry body. Aims.

Keck and Gemini Characterization of Hayabusa2# Rendezvous Target 1998 KY26

The Astronomical Journal
Near-Earth object (NEO) 1998 KY _26 is a target of the Hayabusa2# spacecraft, which it will rendezvous with in 2031 July. The asteroid has been noted to rotate rapidly and has a large out-of-plane nongravitational acceleration.

Radiation Forces and Trajectory of Hayabusa2♯ Target 1998 KY26

The Astrophysical Journal Letters
Small near-Earth asteroid 1998 KY _26 has recently become an object of interest because it is the target of the Hayabusa2 ♯ mission and because challenges in fitting its astrometric data have led to classifying it as a dark comet.
