Far Greater Population of Flow Deposits Around Mercurian Impact Craters than Previously Known [#2322]
Global survey of flow features around craters on Mercury, identifing at least 39 examples. Distribution, characteristics, and potential origins considered.

Distal Flows Associated with Some of the Best-Preserved Craters on Mars: Implications for Extensive Impact-Related Landscape Modification (an Update) [#1593]
Updated analysis of impact craters on Mars with expansive distal flow deposits (DFDs): Consistent flow phenomena within several distal ejecta zones is reported.

Neish C. D.* Virkki A. K.

The Unusual Surface Texture of Venusian Impact Ejecta [#1052]
Melt flows like lava / Smooths venusian ejecta / Botox for craters.

Alexander A. M.* Grimm R. E. Kirchoff M. R.

Formation of Layered-Ejecta Craters During Martian Glaciations: Insights from Numerical Modeling [#2795]
We model impacts with iSALE 2D to asses the minimum thickness of surface ice needed to form layered-ejecta craters on Mars.

A Drone-Based Thermophysical Investigation of Barringer Meteorite Impact Crater Ejecta [#2479]
Meteor Crater / Drone-based thermal inertia / What can it tell us?

3:30 PM

Prieur N. C.* Amaro B. Gonzalez E. Rubanenko L. Xiao Z. et al.

Distribution of Impact-Generated Boulders on Planetary Surfaces: Influence of Target Fracturation and Lithology [#2903]
A CNN is used to detect boulders around fresh impact craters. This database helps us understand the effect of target properties on crater ejection mechanisms.

3:40 PM

Extensive Secondary Cratering in the ExoMars Landing Site at Oxia Planum [#1113]
Small craters abound / Perhaps most from Mojave / ExoMars can test.

3:50 PM

Chertok M. A.* Lucey P. G. Costello E. S. Ireland S. M.

Mare Protolith Properties and Secondary Impacts Inferred from Rocky Crater Populations [#1339]
We identify controls on rock abundance in crater ejecta by inspecting the size-frequency distributions of rocky crater populations across the lunar maria.

Miklavcic P. M.* Lee M. Tokar E. Askari H.

Examining Froude Number as a Scaling Factor for Granular Media in Changing Gravity Using Dynamic Resistive Force Theory [#2863]
Dynamic Resistive Force Theory is modified to study Froude number scaling for oblique granular impacts in varying gravity. Discrete simulations verify findings.

4:30 PM

Yamaguchi Y.* Nakamura A. M.

Laboratory Experiments on Effect of Target Properties on Impact Ejecta Escaping from Martian Surface [#1304]
We performed impact experiments to study the size-velocity-ejection angle relationship for ejecta faster than kilometers per second and its dependence on target properties.
