Isotopic Compositions of Noble Gases and Nitrogen in the Ryugu Samples Returned by Hayabusa2

open access: yes, 2022
In December 2014, the hayabusa2 spacecraft launched to visit the C-type asteroid (162173) Ryugu to bring back surface and subsurface materials to the Earth.

Noble gases and nitrogen in material from asteroid Bennu

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Hayabusa2 Surface and Shock Layer Radiation from the Australian Airborne Observation [PDF]

open access: yes
Characterization of the radiating flowfield around a spacecraft during its atmospheric entry is of significant value for heat shield design. The reentry of the Hayabusa2 sample return capsule (SRC) was observed from an airborne platform by the Australian

Spectral Type and Geometric Albedo of (98943) 2001 CC21, the Hayabusa2# Mission Target

open access: yes, 2023
We conducted optical polarimetry and near-infrared spectroscopy of JAXA's Hayabusa2# mission target, (98943) 2001 CC21, in early 2023. Our new observations indicated that this asteroid has a polarimetric inversion angle of ~21 deg, absorption bands ...

Sample collection from asteroid (162173) Ryugu by Hayabusa2: Implications for surface evolution [PDF]

open access: yes, 2020
The near-Earth asteroid (162173) Ryugu is thought to be a primitive carbonaceous object that contains hydrated minerals and organic molecules. We report sample collection from Ryugu’s surface by the Hayabusa2 spacecraft on 21 February 2019.

Visible, near‐, and thermal infrared spectra of asteroid Bennu samples: Relationship to and implications for remote sensing of carbonaceous asteroids

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Remote spectroscopy is used to characterize the mineralogy and infer the history of planetary bodies. Carbonaceous asteroids, such as B‐type (101955) Bennu, represent the earliest stages of planet formation. B types have a blue (negative) spectral slope and comprise <5% of asteroids.

The role of composition in the spectral evolution of carbonaceous asteroids as informed by Bennu sample return

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Near‐Earth rubble‐pile asteroids Bennu and Ryugu are part of the carbonaceous taxonomic complex (C‐complex), and samples returned from both bodies resemble the most aqueously altered carbonaceous chondrites. However, telescopic and spacecraft visible–near infrared (VIS–NIR) reflectance spectra of Ryugu exhibit a red (positive) spectral slope ...
