Phillips C. B.* Ireland S. M.

A Search for Changes on Europa Between the Galileo and Juno Observations [#2719]
Europa’s surface was viewed / By Galileo, then waiting ensued / Then 20 years later / Juno said “Hey there!” / We’ll see what changed, in truth.

2:30 PM

Becker H. N.* Florence M. M. Lunine J. I. Schenk P. M. Hansen C. J. et al.

Complex Features on Europa's Surface Revealed by Juno's Stellar Reference Unit [#1179]
High-resolution imagery of Europa’s surface by Juno’s low-light Stellar Reference Unit has revealed a complex region of the surface between ~0 and 6°N and 43.5 and 51°W.

2:40 PM

Thelen A. E.* de Kleer K. Camarca M. Butler B. de Pater I. et al.

Mapping Europa's Thermal Properties with ALMA [#2884]
Antennas combine / To map Europa’s surface / And the ice beneath.

2:50 PM

Hammond N. P.* Collins G. C. Goodman J. C. Walker C. Chivers C. et al.

Assessing the Relationship Between Fault Morphology and Shear Heating on Europa [#1866]
Shear heating’s an interesting theory / But how can we test such a query? / When fault slip is quicker / Do ridges grow thicker? / The answers are making us leery.

Piecing Together the Chaos Puzzle: A Machine Learning Model for Chaos Block Identification on Europa [#2295]
The chaos puzzle / Is solved through machine learning? / Train it well and see.

3:30 PM

Baby N. R.* Kenkmann T. Stephan K. Wagner R. J.

Polygonal Impact Craters on Ganymede [#1460]
The straight rim segments of PICs and their relationship with adjacent lineaments or fractures could tell us about Ganymede’s tectonic history.

3:40 PM

Bland M. T.* Bray V. J.

Large Shallow Craters on Callisto and Ganymede as an Inevitable Result of Viscous Relaxation [#2104]
An icy crater / Reacts to internal warmth / Depth diminishes.

Panel Q&A

4:20 PM

Cashion M. D.* Johnson B. C. Sori M. M. Gibson H. Turtle E. P.

Double Ridges on Europa Produced by Ice Wedging [#2007]
We use analytical edge dislocations and FEM models to simulate growth of ice wedges in Europa’s shell that causes surface uplift consistent with double ridges.

4:30 PM

Jabaud B.* Artoni R. Tobie G. Le Menn E. Richard P.

Cohesive Properties of Fresh Deposits Analogues on Enceladus and Europa [#2002]
Experimental study on ice powders as analogues of icy regoliths through a rotating drum device, at temperatures close to the surface of Enceladus and Europa.

4:40 PM

Green A. P.* Cooper C. M.

Dripping to Destruction: Exploring Salt-Driven Viscous Surface Convergence in Europa's Icy Shell [#1148]
The presence of salt in Europa’s ice shell may drive convergent tectonics, recycle surface ice, and encourage material exchange between the ice shell and ocean.

4:50 PM

Lien R. R.* Craft K. L. Walker M. E. Patterson G. W. Rhoden A. R.

Static and Time-Dependent Analyses of Tidally Induced Faulting Within Europa’s Ice Shell: Implications for Subsurface Communication Development [#2614]
