Spectral and photometric characterization of (98943) Torifune in preparation for the Hayabusa2# spacecraft flyby

Astronomy & Astrophysics
After a successful sample-return mission to the asteroid (162173) Ryugu, the Hayabusa2 spacecraft is currently on its way to encounter two near-Earth asteroids: (98943) Torifune (formerly known as 2001 CC21) and 1998 KY26.

Hayabusa2 Surface and Shock Layer Radiation from the Australian Airborne Observation

Journal of Spacecraft and Rockets
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

Development of preparation methods of polished sections of returned samples from asteroid Ryugu by the Hayabusa2 spacecraft

Meteoritics & Planetary Science, 2023
Preparation procedures of polished sections of the Ryugu samples returned by the Hayabusa2 spacecraft were established through tests using CI and CM chondrites as analog materials of the Ryugu samples and processing of the Ryugu samples.

Observation of Diffuse Galactic Light Near the Galactic Center with ONC-T on Board Hayabusa2

Astrophysical Journal
Diffuse Galactic light (DGL) is starlight scattered by interstellar dust. In visible wavelengths, earlier studies observed DGL toward regions of low optical depth in high Galactic latitude, and show marginal consistency with a theoretical model assuming ...

Photometry of (162173) Ryugu and its artificial crater as inferred by Hayabusa2/ONC images

Monthly notices of the Royal Astronomical Society
The JAXA/Hayabusa2 rendezvoused with the (162 173) Ryugu asteroid from June 2018 to November 2019, performing an artificial impact experiment on 5th April 2019. The goal of this work is to study the photometric properties’ variation of the target area

Hayabusa2’s Final Target is 3 Times Smaller Than We Thought

EOS
It also spins twice as fast as previous estimates suggested. A spacecraft touchdown will be challenging, but not impossible.

Size, albedo, and rotational period of the Hayabusa2# target (98943) 2001 CC21

Astronomy & Astrophysics
This study aims to determine the size, albedo, and rotational period of (98943) 2001 CC21, a target of the Hayabusa2 extended mission, using thermal data from the Spitzer Space telescope and ground-based observations.

Asteroidal Organics from the Sample Return Mission Hayabusa2 and their Implication for Understanding our Origins

Elements
The C-type asteroid Ryugu samples returned by the Hayabusa2 spacecraft are the chemically most pristine material in the Solar System, as they have not been exposed to terrestrial environments.
