Internal structures of the Galilean satellites

Icarus, 1981
New models for the interiors of Io, Ganymede, and Callisto are proposed. The model of Io consists of a thin, high-rigidity outer layer separated from a solid interior by a thin, molten or partially molten shell. The modulus of rigidity of the outer layer must be at least 100 times larger than that of the underlying partially molten shell.

Strength of the lithosphere of the Galilean satellites

Icarus, 2006
Abstract Several approaches have been used to estimate the ice shell thickness on Callisto, Ganymede, and Europa. Here we develop a method for placing a strict lower bound on the thickness of the strong part of the shell (lithosphere) using measurements of topography.

Galilean satellite mission concepts

Astrodynamics Conference, 1982
Post-Galileo mission concepts considered possible for satellite-intensive investigations are presented, with consideration given to single and multiple target scenarios using orbiter and lander deployments. Candidate missions that satisfy the selected science objectives are identified, and specific scenario/target combinations which fall within ...

Perturbation of an orbiter of a Galilean satellite by the other satellites

Acta Astronautica, 1983
In this paper the perturbation of an orbiter of one of the Galilean satellites by the other Galilean satellites of Jupiter is investigated. The attraction of a perturbing satellite is averaged over one revolution assuming a circular orbit. The perturbation can then easily be represented by elliptic integrals.

Problems on the Galilean satellites of Jupiter

Celestial Mechanics, 1975
The purpose of this paper is to present a critical review of some problems concerning the dynamics of Jupiter's Galilean system of satellites. Theory, ephemeris and observation are considered.

The Atmospheres of Titan and the Galilean Satellites

Journal of the Atmospheric Sciences, 1974
The stability of various atmospheres on Titan and the Galilean satellites is examined relative to escape. One method consists of the comparison of exospheric temperature and a blow-off temperature defined for the various constituents. Another method consists of the evaluation of outflow based on a polytropic model. Hydrogen, methane, nitrogen, and neon

Spin Orientation of the Galilean Satellites

The four Galilean satellites (Io, Europa, Ganymede, and Callisto) are locked in a 1:1 spin-orbit resonance. Their rotation axis is assumed to be in a Cassini state, meaning that the rotation axis follows the long-term precession of the orbit normal. The obliquity of the satellites, which is the angular separation between the rotation axis and the orbit
