Session Introduction

8:25 AM

Ren J.* Hesse M. A. Melwani Daswani M.

Permeability Limited Compaction of Ceres' Rocky Core [#1803]
With consideration of Darcy’s flow, compaction of Ceres’ core is also limited by permeability, resulting a porous core at the final stage.

8:35 AM

Pamerleau I. F.* Sori M. M. Scully J. E. C.

An Ice-Rich Crust with Unrelaxed Craters on Ceres Reflects an Ancient Frozen Ocean [#1359]
A top-down frozen ocean on Ceres yields an ice-rich crust that explains crater relaxation and morphology and matches gravity inversions and thermal models.

8:45 AM

Reynoso L. R.* Robinson K. J. Root R. A. Williams L. B. Castillo-Rogez J. et al.

Positive Glycine Incorporation in Ceres Analogue Minerals [#1321]
Europa, Enceladus, Ceres Brines Laboratory Studies Glycine in salt confirmed!

8:55 AM

Rizos J. L.* Sunshine J. M. Farnham T. L. Kloos J. Daly R. T. et al.

Unusual Subsurface Deposits Exposed at the Yalode-Urvara Basins on Ceres [#1656]
We report unusual subsurface deposits exposed at the Yalode-Urvara basin, compatible with the presence of carbonates, which may also contain organics.

Panel Q&A

9:25 AM

Sizemore H. G.* Crown D. A. Scully J. E. C. Berman D. C. Neesemann A. et al.

High-Resolution Geologic Mapping of Urvara Crater, Ceres: Unit Definitions, Crater Densities and Feature Correlations [#2629]
We detail the process of geocontact mapping in the interior of Urvara Crater, Ceres, and evaluate the possible cryovolcanic origin of crater floor materials.

9:35 AM

Bickham D. A.* Schenk P. M.

Geologic Mapping of Smooth Plains on Dione: Insights into Resurfacing Processes on Icy Bodies [#2930]
Geologic mapping of Dione to determine origin of resurfaced plains and to better understand geologic processes on icy bodies as a whole.

9:45 AM

Beddingfield C. B.* Cartwright R. J.

Uranus’ Moon Miranda Exhibits a Thick Regolith from an Unknown Source [#1274]
We investigated Miranda’s “muted” craters and scarps and found that they are consistent with a thick mantling regolith from an unknown source.

9:55 AM

Strom C. A.* Nordheim T. A. Patthoff D. A.

Constraining Ocean and Ice Shell Thickness on Miranda from Surface Geological Structures and Stress Modeling [#1207]
Miranda’s unusual surface geology may be the result of a subsurface ocean ~25 km thick based on the results of this study.

Panel Q&A

10:25 AM

Parekh R.* Pappalardo R. Scully J. E. C. Cameron M. E.

Small-Scale Mass Movements on Europa, Callisto and Ganymede [#1876]
In this study, I identified and report various small-scale mass movements on the surface of Europa, Callisto and Ganymede in order to understand the surface regolith dynamics.

10:35 AM

White O. L.* Singer K. N. Williams D. A. Moore J. M. Lopes R. M. C.

Is True Polar Wander Recorded in Pluto's Ancient Geology? [#1286]
The configuration of geological units in the oldest terrains of Pluto may record an orientation of Pluto’s spin axis that is different from its current one.

10:45 AM

Mishra I.* Buratti B. J. Dhingra R.

How Widespread are the Bladed Terrains on Pluto? [#1787]
We are comparing the photometric properties of the bladed terrains on Pluto with the poorly imaged regions that have been hypothesized to be similar.

10:55 AM

Denton C. A.* Gosselin G. J. Freed A. M. Johnson B. C.

The Formation and Evolution of the Sputnik Basin, Pluto, Prior to Nitrogen Ice Fill [#1076]
We simulate Sputnik Planitia, Pluto’s largest impact basin, from formation through cooling and relaxation prior to loading of the basin with nitrogen ice.
