Session Introduction

8:25 AM

Bottke W. F.* Vokrouhlicky D. Marschall R. Nesvorny D. Morbidelli A. et al.

Exploring the Missing Early History of the Giant Planet Satellites [#1581]
We show most satellites have ancient surface ages yet have lost the first ~100 million years of their histories via massive early impacts that caused global erasure.

8:35 AM

Ferguson S. N.* Rhoden A. R. Kirchoff M. R.

Satellite Bookends: Utilizing the Cratering Histories of Mimas and Rhea to Examine the Formation Ages of the Saturn System [#2858]
We analyze the impact crater populations for circular and elliptical craters on Saturn’s moons Mimas and Rhea in an effort to examine their formation ages.

8:45 AM

Bierson C. J.* Fortney J. J. Trinh K. T. Kreslavsky M.

The Effect of Jupiter’s Early Luminosity on the Galilean Satellites [#2263]
After its formation, Jupiter was ten-thousand times more luminous than it is today. We explore the implications of this heating on the Jovian satellites.

8:55 AM

Kegerreis J. A.* Teodoro L. F. A. Cuk M. Cuzzi J. N. Eke V. R. et al.

A Recent Impact Origin of Saturn's Rings and Mid-Sized Moons [#2658]
Saturn’s young rings and mid-sized moons could form after an impact between precursor moons sends debris as far as the Roche limit, high-res simulations show.

9:05 AM

Panel Q&A

9:25 AM

Zhang Z.* Bolton S. J. Brown S. Bonnefoy L. E. Ermakov A. et al.

Juno Microwave Radiometer Observations of Europa's Ice Shell [#2314]
Preliminary results from Juno’s Microwave Radiometer observations of Europa will be presented along with a comparison to MWR measurements obtained at Ganymede.

9:35 AM

Soderlund K. M.* Lemasquerier D. Bierson C. J.

Europa's Ocean Translates Interior Tidal Heating Patterns to the Ice-Ocean Boundary [#2731]
We show that ocean convection largely transposes the tidal heating pattern at the seafloor to the ice-ocean boundary.

9:45 AM

Dawson H. G.* Byrne P. K. Klimczak C. Regensburger P. V. Vance S. D. et al.

The Tectonic State of Europa's Seafloor Limits Potential Water-Rock Interactions There [#2822]
Modeling of the seafloor strength of Europa indicates that tidal and contractional stresses cannot cause faulting, limiting water-rock interactions.

9:55 AM

Tomlinson T. C.* Buffo J. J. Meyer C. R.

Testing Permeability-Porosity Relationships for Modeling Icy Shells [#1998]
Understanding permeability-porosity relationships in a two-phase model is imperative for accurate modeling of icy satellite shells.

10:05 AM

Panel Q&A

10:25 AM

Kang W.* Jansen M. F.

Different Ice Shell Geometries on Europa and Enceladus Due to Their Different Sizes: Impacts of Ocean Heat Transport [#1028]
We use geostrophic turbulence theory to predict the amount of heat transport in icy moon oceans and thereby the equilibrium ice thickness gradients.

10:35 AM

Berne A.* Simons M. Keane J. Park R.

Using Tidally Driven Elastic Strains to Infer Regional Crustal Thickness and Ocean Salinity at Enceladus [#1899]
Tides that deform crust / Betray the crustal thickness / Salinity too.

10:45 AM

Castillo-Rogez J. C.* Weiss B. P. Beddingfield C. B. Biersteker J. B. Cartwright R. J. et al.

Preservation of Deep Oceans in the Uranian Moons, Predicted Compositions, and Physical Characteristics [#1808]
They might have oceans / Those Uranus moons are cool / Let us explore them!

10:55 AM

Rhoden A. R.* Rudolph M. L. Manga M.

The Challenge of Ocean-Sourced Cryovolcanism on Charon [#2941]
Cracks and canyons form / But not cryovolcanism / From Charon’s deep freeze.
