Cassini Observes the Active South Pole of Enceladus
TLDR
The shape of Enceladus suggests a possible intense heating epoch in the past by capture into a 1:4 secondary spin/orbit resonance. Expand
Cassini Imaging of Jupiter's Atmosphere, Satellites, and Rings
TLDR
Findings on Jupiter's zonal winds, convective storms, low-latitude upper troposphere, polar stratosphere, and northern aurora are reported, including previously unseen emissions arising from Io and Europa in eclipse, and a giant volcanic plume over Io's north pole are described. Expand
Enceladus's measured physical libration requires a global subsurface ocean
Abstract Several planetary satellites apparently have subsurface seas that are of great interest for, among other reasons, their possible habitability. The geologically diverse saturnian satelliteExpand
Shapes of the saturnian icy satellites and their significance
The sizes and shapes of six icy saturnian satellites have been measured from Cassini Imaging Science Subsystem (ISS) data, employing limb coordinates and stereogrammetric control points. Mimas,Expand
Eruptions arising from tidally controlled periodic openings of rifts on Enceladus
TLDR
A mechanism in which temporal variations in tidal stress open and close the tiger-stripe rifts, governing the timing of eruptions is reported, implying that Enceladus’ icy shell behaves as a thin elastic layer, perhaps only a few tens of kilometres thick. Expand
Galileo Encounter with 951 Gaspra: First Pictures of an Asteroid
TLDR
Galileo images of Gaspra reveal it to be an irregularly shaped object that appears to have been created by a catastrophic collisional disruption of a precursor parent body. Expand
Observation of moist convection in Jupiter's atmosphere
TLDR
It is concluded that moist convection—similar to large clusters of thunderstorm cells on the Earth—is a dominant factor in converting heat flow into kinetic energy in the jovian atmosphere. Expand
Physical characterization of asteroid surfaces from photometric analysis
The feasibility of using photometric models like Hapke's (1981, 1984, 1986) equation for deriving physical properties of asteroids from photometric observations is discussed. Using data for Ceres andExpand
Cassini Imaging Science: Initial Results on Saturn's Rings and Small Satellites
TLDR
Images acquired of Saturn's rings and small moons by the Cassini Imaging Science Subsystem have produced many new findings, including new saturnian moons; refined orbits of new and previously known moons; ring particle albedos in select ring regions; and never-before-seen phenomena within the rings. Expand
Cassini Imaging Science: Initial Results on Phoebe and Iapetus
The Cassini Imaging Science Subsystem acquired high-resolution imaging data on the outer Saturnian moon, Phoebe, during Cassini's close flyby on 11 June 2004 and on Iapetus during a flyby on 31Expand
