Rüsch O.* Patzek M.

Intense Fracturing but No Flaking on CM-Like Asteroids Due to Thermal Fatigue — Implications for Bennu [#1992]
More than 2000 hours of thermal cycling on meteorites performed in the lab reveal which, and how, meteorites crack and flake.

2:30 PM

Durda D. D.*

Impact Experiments into Bennu- and Ryugu-Like Regolith Simmulants I: Boulder Fracture Progression [#1170]
Laboratory impact experiments into blocks and coarse regolith simulant for interpretation of observed boulder and impact crater morphologies on Bennu and Ryugu.

2:40 PM

Ciceri F.* Hildebrand A. R. Hanton L. T. J.

Mechanical and Elastic Properties of Chondrite Litholgies [#2967]
Static mechanical and elastic properties of meteorite lithologies show significant variation reflecting their mineralogy, porosity, and parent body history.

2:50 PM

Nagaashi Y.* Nakamura A. M.

Weak and Size-Independent Cohesive Force of Meteorite Fragments: Implications for Mobility of Particles on a Small Body [#1023]
We show that the cohesive force of meteorite fragments is weak and size-independent, which is likely related to the high mobility of asteroid particles.

Ultraviolet to Near-Infrared Spectral and Photometric Measurements of 162173 Ryugu Powders [#2784]
We present photometric and reflectance spectroscopy analysis of Ryugu powders from grain C0002 reproducing common observation geometries performed by Hayabusa2.

3:40 PM

Pilorget C.* Okada T. Bibring J.-P. Brunetto R. Hamm V. et al.

A Global Characterization of Pristine Ryugu Samples with the NIR Hyperspectral Microscope MicrOmega Within the ISAS Curation Center and Perspectives for the Bennu Samples [#2510]
We present the results of MicrOmega extensive observations of the Ryugu samples (bulks, small bulks and > 400-mm-sized grains) in their pristine condition.

3:50 PM

Hamm M.* Hamilton V. E. Goodrich C. A.

Mid-IR Spectrum of Ryugu Sample C0137 Compared to In-Situ Data and Carbonaceous Chondrites [#2221]
The MIR spectrum of Ryugu sample C0137, taken from the second sampling site close to an artificial crater is compared to in-situ measurements of MARA from Ryugu.
