Session Introduction

8:25 AM

Lawrence D. J.* Stockstill-Cahill K. R. Jozwiak L. M. Peplowski P. N. Wilson J. T.

Enhanced Thorium Abundances at Lunar Irregular Mare Patches [#2284]
Moderately enhanced thorium abundances (3 to 8 ppm) are observed in the areas around lunar irregular mare patches.

8:35 AM

Byron B. D.* Elder C. M. Glotch T. D. Hayne P. O. Pigue L. M. et al.

Observations of Rock-Poor Material at Lunar Red Spots: Insights from Thermal Infrared and Radar Data Sets [#2650]
We analyze lunar red spots with thermal IR and radar data. They are generally rock-poor with low thermal inertia and low CPR, due in part to pyroclastics.

8:45 AM

Rajasekhar R. P.* Bhattacharya S. Pathak S. Naik S. S. Bhiravarasu S. S. et al.

Evidence for Young Lunar Volcanism in Mare Vaporum Region from Multi-Wavelength Remote Sensing Observations [#2249]
synergistic study of two domes located in the Mare Vaporum region was carried out using CH-2 TMC and complimentary remote sensing data sets from recent missions.

8:55 AM

Morgan G. M.* Campbell B. A. Weitz C. Jawin E. R. Berman D. et al.

Volcanic History of Mare Crisium: A Multiwavelength Radar Perspective [#2847]
We will discuss the results of integrating Earth-based and Mini-RF bistatic data to map out volcanic deposits/structures within Mare Crisium.

9:05 AM

Panel Q&A

9:25 AM

Cuevas-Quiñones S.* Bramson A. M. Rubanenko L.

Automated Crater Morphology Characterization on the Moon Using an Unsupervised Neural Network [#2468]
We test the use of an autoencoder for systematic characterization of crater morphology and find it can distinguish well-defined crater rims from degraded rims.

9:35 AM

Ghent R. R.* Costello E. S. Parker A. H.

Characteristics of the Moon's Young Crater Population: Caught Between a Rock and a Rayed Place [#2690]
Many lunar rays at equator / Are they born there faster? / Or do they die faster elsewhere? / We try to find the answer / (Rocks don’t seem to care).

9:45 AM

Liu T.* Michael G. Wünnemann K.

The Timeline of Early Lunar Bombardment Constrained by the Evolving Compositions of Differently-Aged Melt [#1249]
The impact rate function of early lunar bombardment more likely has an exponential tail-off.

9:55 AM

Chakraborty T.* Putrevu D. Bhiravarasu S. S. Das A. Pandey D. K. et al.

Investigating the Effect of Crater Evolution Process on the Radar Scattering Behaviour of the Lunar Craters Using Chandrayaan-2 Dual-Frequency SAR Data [#2006]
The abstract reveals dominance of crater degradation process on change in the physical nature of various impact craters leading to radar scattering variability.

10:05 AM

Panel Q&A

10:25 AM

Powell T. M.* Williams J.-P. Greenhagen B. T. Hayne P. O. Paige D. A.

Discovery of a Lunar Cold Spot at the Apollo 16 South Ray Crater [#2780]
We identify a cold spot around the Apollo 16 South Ray crater. Astronaut footprint depths and thermal modeling indicate a decrease in regolith density.

10:35 AM

Frizzell E. S.* Hartzell C. M.

Material Property and Particle Distribution Effects on Unconfined Inertial Dilation [#2737]
Simulations investigating the expression of surface dilation as the result of granular shocks with the motivation of understanding lunar cold spot formation.

10:45 AM

Weirich J. R.* Domingue D. L. Chuang F. C. Sickafoose A. A. Richardson M. D. et al.

Reiner Gamma Swirl: Bright Albedo Features Trend Lower than Surrounding Topography [#1271]
We find the bright on-swirl units are 4 meters lower than the dark off-swirl units at Reiner Gamma. Perhaps elevation plays a role during swirl formation.

10:55 AM

Bürger J.* Blum J. Gundlach B. Hayne P. O. Läuter M. et al.

Derivation of Lunar Regolith Properties from LRO/Diviner Data and Thermophysical Modeling [#1185]
We present a microphysical thermal model for the lunar regolith and derived regolith properties, such as grain radius and stratification properties.
