Evidence of Space Weathering on the CI1-Chondrite Asteroid 162173 Ryugu [#1040]
A 6 nm shift in the 2.7-micron band positoin between returned samples and the surface materials of asteroid Ryugu indicates space weathering by solar wind.

8:35 AM

Hallatt D.* Wozniakiewicz P. J. Burchell M. J. Leroux H.

How do Ryugu-Inspired Phyllosilicates Respond to Micro-Mechanical Impact? [#2084]
Phyllosilicates have been shot with micrometer-scale projectiles at <6 km/s. We report on the morphology of the resultant craters.

8:45 AM

Melendez L. E.* Thompson M. S. Keller L. P. Snead C. J.

Characterizing Space Weathering Features in Grains from Asteroid Ryugu [#2069]
Winds of yesterday / The smallest meteorites / Remnants of times past.

8:55 AM

Laczniak D. L.* Thompson M. S.

Space Weathering Effects Revealed Through In Situ Ion Irradiation and Heating of the Murchison Meteorite in the Transmission Electron Microscope [#1176]
In situ H+ and He+ irradiation and subsequent rapid heating of Murchison dust reveals the combined effects of solar wind and micrometeoroid space weathering.

Panel Q&A

9:25 AM

Cartwright R. J.* DeColibus D. R. Castillo-Rogez J. C. Beddingfield C. B. Grundy W. M. et al.

Are Nitrogen-Bearing Species Present on Uranus' Moon Umbriel? [#1268]
We analyzed the near-infrared spectral properties of the uranian moon Umbriel to investigate whether ammonia and other nitrogen-bearing species are present.

9:35 AM

Hibbitts C. A.* Stockstill-Cahill K. Lloyd E.

Spectral Effects of Electron Irradiation on Cryogenic Hydrated Minerals and Brines Relevant to Europa [#2667]
Space weathering of cryogenic salts and brines by high-energy electrons results in coloring in the visible but does not affect the infrared.

9:45 AM

Schriver D.* Jia X. Domingue D.

Mapping Particle Precipitation on Tethys' Surface to Understand Space Weathering of Its Regolith [#1729]
The precipitation of saturnian magnetospheric particles onto Tethys’ surface is examined to explore space weathering of the moon’s icy regolith.

9:55 AM

Kling A. M.* Greer J. Thompson M. S. Heck P. R. Isheim D. et al.

Solar Wind-Sourced Water Stored in Nanoscale Reservoirs in Lunar Soil Grains [#1710]
Moon water from Sun / Is not so ephemeral / It’s trapped in small voids.

Panel Q&A

10:25 AM

Cymes B. A.* Burgess K. D. Stroud R. M. ANGSA Science Team 

Comparison of Space Weathered Lunar Olivines of Varying Maturity, Recent Exposure, and Curation Temperature [#2599]
Lunar olivine may have a characteristic “style” of solar wind-driven space weathering controlled by its crystal structure.

10:35 AM

Sorokin E. M.* Yakovlev O. I. Slyuta E. N. Gerasimov M. V. Zaitsev M. A. et al.

Chemical Composition of the Nanophase Iron (NpFe0) Obtained in the Laser Experiment [#2156]
In our experiment, large npFe0 spherules (up to 5 μm) were obtained in basalt glass and olivine, their chemical properties were measured using a SEM.

Cahill J. T. S.* Cahill K. R. S. Hibbitts C. A. Livi K. Waller C. D. et al.

Implications for Interpreting LRO LAMP Observations from an Examination of Apollo 16 Highlands Soils in the FUV Through MIR [#2867]
Space weather changes / Light reflects in VIS-IR / But UV tells more!

10:55 AM

Wöhler C. Bhatt M. Arnaut M.*

Localized Polarization Behavior and Inferred Grain Size Distribution at the Lunar Swirl Reiner Gamma in Comparison to Crater Rays and Ejecta Blankets [#1599]
This study examines the regolith grain size distribution at the lunar swirl Reiner Gamma and nearby locations based on new telescopic polarimetric imaging data.
