Reorientation 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 کاملCartographic and Topographic Mapping of the Icy Satellites of the Outer Solar System
Cartographic and topographic mapping of the major satellites of the Outer Solar System has been in progress since the late 1980’s, beginning with Voyager image data, and incorporating Galileo and recently Cassini imaging data as released to the public. Global image mosaics, based on cartographic control nets, have been produced for all these satellites. In addition, digital topographic maps hav...
متن کاملRed, Gray, and Blue: Near Infrared Spectrophotometryof Faint Moons of Uranus and Neptune
Using the CoCo Cold Coronagraph at NASA’s Infrared Telescope Facility on Mauna Kea, we observed the uranian satellites Miranda, Puck, Portia, and Rosalind and the neptunian satellite Proteus in the near infrared (JHK) to determine the albedos of those faint satellites. In V-J, all of Puck, Portia, Rosalind, and Proteus are very blue, similar to the colors of many icy satellites and of water ice...
متن کاملThermal- and Plasma-Induced Molecular Redistribution on the Icy Satellites
The molecular transport of condensed gas species across the surfaces of the icy satellites of Jupiter and Saturn is examined with the view of describing, in part, certain gross visual features associated with these bodies. Molecular redistribution induced by thermal sublimation and magnetospheric plasma-ion impact on satellites with negligible atmospheres is calculated by assuming that the mole...
متن کاملCan There Be Dissipation without Heat? Constraints on Tidal Dissipation in the Medium-sized Saturnian Satellites
Introduction: Much can be learned about tidal dissipation in icy bodies by studying the medium-sized Saturnian satellites. They have densities that range between 960 kg/m3 (Tethys) and ~1460 kg/m3 (Dione) [1]. They accreted very cold (e.g., [2]). Thermal models governed by the decay of long-lived radionuclides yield freezing of the smallest satellites, in a few hundred million years. A Maxwell-...
