Convection in ice I shells and mantles with self-consistent grain size
[1] The viscosity of ice I is grain size dependent for temperature and stress conditions appropriate for ice I shells and mantles of large and midsized icy satellites. Satellite thermal evolution, heat flux, critical shell thickness for convection, brittle/ductile transition temperature, and potential for surface deformation are therefore grain size dependent. Using measured grain sizes from te...
متن کاملReorientation of icy satellites by impact basins
[1] Large impact basins are present on many of the icy satellites of the outer solar system. Assuming that their present-day topography is uncompensated, such basins can cause significant poleward reorientations for slow-rotating satellites. This reorientation may have been accompanied by transient large-amplitude wobble. The largest basins on Tethys, Rhea and Titania are predicted to have caus...
متن کاملTectonics of the outer planet satellites
Tectonic features on the satellites of the outer planets range from the familiar, such as clearly recognizable graben on many satellites, to the bizarre, such as the ubiquitous double ridges on Europa, the twisting sets of ridges on Triton, or the isolated giant mountains rising from Io’s surface. All of the large and middle-sized outer planet satellites except Io are dominated by water ice nea...
متن کاملSeas under Ice: Stability of Liquid-water Oceans within Icy Worlds
Introduction: The possible existence of internal oceans in some icy bodies of the outer Solar System has been suggested through the last years in a joint of observations that cover a wide range of evidences: magnetic fields in Europa and Callisto [1,2], and possibly Ganymede [3], induced by Jupiter’s plasma environment in an electricity-conducting layer near the surface of these satellites, lik...
متن کاملViscous Relaxation of Impact Craters on Icy Planetary Surfaces: Determination of Viscosity Variation with Depth
Spacecraft images show that the icy Galilean satellites have surfaces with very low topographic relief. Impact craters on Ganymede and Call&o are anomalously shallow and are characterized by sharp well-defined rims and domed floors. These morphological characteristics can be explained by viscous relaxation of topography on an icy crust in which the viscosity is uniform or decreases with depth. ...
